Maybe it is just a very specific human trait to feel the need to shout out our existence to the universe. The majority of other species might just favor silence and hiding. Camouflage is very common among various species on our planet.
if you always camouflage there is resources of knowledge and other resources that you cannot obtain and after a while you will be behind the others so you have to take the risk to see what others are up to do
It’s a haunting hypothesis to wonder whether millions of other civilisations might be thinking exactly the same thing - all locked in 🔒 by the laws of relativity and the speed of light.
A very real possibility. If we develop the tech to see "life signatures" way the hell out there then that question will be confirmed...all we can do is wave to each other from a distance...heck, we might not even be able to see each other waving...ever.
@@byronlemay2166 Did you see the latest research on whether aliens would be able to see the Earth transiting the sun? It was really interesting. I interviewed the researcher and she mentioned how tough it might be for us even to notice one another. “Ships in the night” was the phrase she used.
@@BadBoyofScience tbh seeing earth, technologically speaking, is going to be really hard - they basically have to be within 100 light years of us, or it might as well be looking at us during the dark ages. however, if they can keep an eye on our star, they could potentially tell that there's oxyen in the air when the earth is between our star and them - and oxygen in the air, given how reactive it is, means there's something there generating said oxygen.
@@leeman27534 Yep - but they have to be looking for us. They have to have the right alignment with respect to us. They have to have the correct technology to see us and we have to have not wiped ourselves out by then ;) It’s tough! Come on. I just want aliens 👽 in my lifetime ;)
Sorry to burst your bubble but you’ll die long before we find aliens. They are so far away our technology isnt yet capable of finding life. Maybe in 100 years.
well it goes both ways : because without intelligence what do you have ?! some species unaware of their own existance just sitting there for a few million years on a piece of rock waiting to be hit by an asteroid or to be wiped out by some other exctincion level event . also fermi paradox is not really a paradox , considering how vast is our galaxy alone and how primitive and brief our attempts for interstellar communication have been . even if there is only 1 civilization per 100 galaxies , there still must be a lot of them . and we can´t even leave our solar system yet . another thing to consider is what makes us think that type 2 or 3 civilization even wants to communicate with us , if we are like monkeys to them intelligent wise .
Why are people so self loathing on social media? It's quite interesting to see the difference in psyche between someone on UA-cam or other platforms for a major portion of their day opposed to people that go out and do things with their day that are productive.
@@jmgonzales7701 if there are perfect conditions for life for us, then in a infinite constantly expanding universe there is bound to be life outside of our own
@@toxiflexx04 Possibility is non as well. Also why do we want life other than we? those civilizations could be the end of us. better not getting in contact with them
What we consider intelligence can be equivalent to what an alien species would consider to be a sensory characteristic like sight. Their intelligence could be unfathomable to us.
Still intelligence, an organism capable of processing, storing and analizing a large number of sensory imputs beyond instinct behavior, I know that is a very large gap from an ant but still recognizable. I don´t believe in that analogy of humans beeing like ants to aliens, we don´t feel the same way about ants than dogs or dolphins, or monkeys. And we don´t treat them the same. Buuuut.... when you think of clashing cultures you could be more scared of Aliens thinking of humans as dogs than ants, you barely notice ants, and they live better that way! hahahahah :P
@@oraculox I agree with what you are saying, let's take it a step farther, compare the technology we have in 2021 and compare it to the technology we had in 1971 (that is 50 years' time) which is NOTHING compared to human history. If you travel back in time to 1971 with an iPhone and walked into NASA their heads would explode. So imagine an Alien civilization that might be 500-1,000 years ahead of us in technology to them we would seem like toddlers playing with leggos. The history here on Earth has shown us that every time an "Advanced Civilization" has encountered a less advanced civilization it has not turned out good for the less advanced civilization. Europeans coming to North America, the Spanish going to South America, The Romans moving throughout Europe, the list goes on and on. Intelligence might be our undoing because we might actually use our technology to reveal our location to a much more advanced civilization and they come here and do to us what more advanced civilizations do to less advanced civilizations. BAD THINGS MAN,,, BAD THINGS,,,LOL
@@tbirum Of course. But there is stagnation between leaps of evolution. On our level of cognitive response and reasoning is kind of fair to say we won´t have another leap for quite some time. We can speculate on tecnological achievement, but we are aproaching a valley in the learning curve regarding quantum phisics. In that valley of "need" we could see an evolution of the brain, or watch entropy at it´s best hhahhah
That’s as inaccurate as the Drake equation. Intelligence means what it means. Ability to advance throughout the lifespan of the species. A monkey gets lucky and uses a stick to do some things but isn’t intelligent enough to pick out a good stick and work it and keep it for that task
That's because it's not a paradox. Threw me too. It should be called Fermi's quip, since he was just joking. A paradox is two logical statements that contradict each other. This does not.
@@-Subtle- I thought it was called a paradox because we don’t see any aliens or life any where else but the evidence says that there should be life other than us.
Just mathematically there has to be a lot of intelligent life in the Universe. The problem is that where ever they are, they are stuck where they are at just like us. The tremendous challenges of long duration space travel are too prohibitive to overcome. Biological life forms are too fragile for long duration space travel.
Why does it have to be long duration? Traveling at near light speed would seem to be a short trip to the person making it, and we already know of one way to bypass the light speed barrier that isn't in violation of the laws of physics as we understand them. Who's to say that another species hasn't cracked the how of doing it, or have some other science we simply haven't discovered yet. For all of our advances, there is still so much we don't yet understand.
@@JoeSilverhand The reason it has to be long duration is the distance to the nearest star. Even at the speed of light it would take years to get there. If you are traveling to a star system that is 100 light years away, that is 100 years of travel. The propulsion system and fuel required are just the fist extreme challenge to overcome. Please share with NASA your solutions to Interplanetary, Interstellar and Intergalactic travel. They will hire you and pay extremely well.
The fact that we haven’t yet discovered life speaks to how small and isolated we are and how big our universe and space is. Surely other life exists but the sheer size of the “playing field “ is incomprehensible.
I think we're surrounded by intelligent life who are having the same conversation. They know we're out there but realize they might not ever get to make contact much less visit.
I personally don't believe humans have reached the 'Great Filter' yet and there are other species out there at least as advanced as us. That said, humans will likely destroy the planet before we get to a level of technology where we could conceivably send humans to another star system. The distances in space are just that great.
Can't wait to find another intelligent alien species, and they turned out to be monotheistic, believing THEY are made in image of their God; and they declares inferior because we don't like like them(who are made at image of God), and declare every religion in Earth as pagan/heretics and they do to us the same Christians and Muslims have done to themselves in history because of holy wars.
I think the answer is that evolution of intelligent self-awareness is highly circumstantial. Prokaryotic life may exist everywhere you find liquid water. But here on Earth, three key random instances caused it to evolve further. First: The Great Oxidation event likely changed the chemical composition of Earths oceans, causing a microbial mass extinction allowing for the evolution of Eukaryotes. Second: The Cryogenian glaciation may have initiated the evolution of multicellularity. And thirdly and most notablly, the asteroid impact which wiped out the dumb Dinosaurs allowing for the proliferation of mammals that ultimately allowed us to evolve. Now consider that this random succession of important occurrences never happened on other goldilocks worlds and you have your explanation of the Fermi paradox. Earth may be an example of a relatively unique and rare phenomenon where the evolutionary dominos fell in just the right order to allow for the emergence of technological intelligence.
Or we could just be first. Earth 5 billion years old, universe 13.5 billion. We are just a baby. Maybe the universe will be filled with life when it hits 50 billion years old.
There's absolutely nothing to indicate that dinosaurs were any less intelligent than modern animals, that's a very common misconception. For all we know if the K-T extinction had never happened then a space faring civilization might have developed on Earth several million years earlier. It's pure speculation.
To your last point, we can never know the number of combinations of events that could occur that could cause life to form. For instance, imagine there was a dead planet orbiting a star that passed close to a black hole. The immense gravity changed the orbit of the planet into a more favorable position, and somehow kickstarted tectonic movement of the plates of the planet. This caused geological activity, which when combined with the new orbit warmed the planet enough to allow chemical compounds to form that can support silica*based life (because theoretically Carbon isn't the only elementt that can form the chemicals of a primordial soup.), And now life of an entirely different order exists from some extremely unlikely circumstances, just like ours. Considering how big the universe is and how many combinations of events can take place, it seems more an eventuality than a possibility. I would tend to believe that the great filter is the formation of the eukaryotic cell. The circumstances of their existence are to specific and strange that it boggles the mind. According to the most widely held belief, a cell attempted to consume another cell, however the prey cell was not consumed, and instead somehow ended up both producing energy for the predator cell (forming the mitochondria) and interfacing with it's DNA in a way that caused the predator cell to build a copy of the prey cell within itself that fulfilled the same purpose. While the hand waving answer of "we're talking about a billion or more years, it was bound of happen eventually", is applicable, I counter it with the notion that in the several billion years following, it was not observed to happen again, nor anything tantamount to it. That occurrence, I believe, is about as unique as the order of a deck of cards, improbable to where it will never be seen again.
If you think there is no, or can’t be life elsewhere...in a universe tens of billions of years YOUNG, with trillions of suns, you’re a lot like flat earthers.
It's funny how we want to find alien civilizations in the universe when at the same time we can't even get along with each other in our own civilization.
I saw this story of an alien who really wanted to visit earth so he traveled 3.7 billion light years just to get here. And when he finally arrived, he stepped out of his craft, and the earth was basically a dystopia with no life at all. The amount of time it would take to get here is genuinely that staggering that honestly if you think abt it, it’s pretty believable. I mean, it takes about 9.5 years to get to Pluto. And we’ve obviously been observing(somehow)planets even farther away so it’s not hard to believe that if there was anyone out there, by the time they get here, no one reading this comment would be alive to see it. Which means we’re basically alone. And if there is other life similar to us(not fantasy aliens with super high tech) they would feel the same, alone. Bc it’s seemingly impossible to get that contact before either one of us went extinct. Now it Kinda sounds like multiverses to me so I’m gonna stop
with infinite energy you could technically get anywhere in 5 minutes. The acceleration of an object is always proportional to the force applied to it and inversely proportional to its mass. So as long as you have energy you can accelerate infinitely. But there is a catch. No matter how fast you go, as soon as you turn on a light in front of you, it will go 300 000 km/s in front of you... and also go at 300 000km/s for an observer on your native planet. So for you it might take 5 mins, but for your people it will still take billions of years for you to take that trip. So your story still makes sens. Not as it takes to much time for the alien to come here, but in how will the state of their own civilization will have changed by the time they come home from their trip.
With our current technology, humans finding another intelligent life form would be the equivalent of me taking you to the beach where I have hid one special grain of sand and I ask you to find it.
We are emitting radio waves regularly since 121 years, so the radio waves must reached a diameter of a little less than 242 light years.. i really doubt that advanced aliens cannot detect primitive commucation like radio waves.
@@grimjowjaggerjak Even if the aliens received the radio waves(242 ly is really small area to be sure that is inhabited by intelligent life), you are assuming that aliens would want anything to do with us.
@@DarkoTrpevski or could even understand what the radio waves are even saying. They say the further the waves go out, the very little about of information is left on that radio wave.
@@grimjowjaggerjak Many of those are probably garbled by the ionosphere. Even those that aren't (like Earth-space communications), by the time they're 100 light-years away, are so attenuated and weak that they're basically undetectable anyway.
Either concept is terrifying and amazing in its own right. If the universe is infinite and we are alone then we would never have to worry about hostile alien species as well had have endless room for expansion. If we are not alone then statistically there would be both hostile and non hostile as well as inconceivably advanced and primitive species. The learning and advancement would be incredible.
why would we ever conflcit with another species, for all we know they could have very different living environments (ones that would be hostile to humans). Also, there are so many planets, hundreds of which are habitable or could be made habitable (probably a lot more than that). So why would we fight if there is so much space? The more advanced a civlization becomes, the more peaceful it becomes, war was much more brutal and common 300 years ago than it is now.
I often think about if we did find extraterrestrial life, how would we communicate with them. What if we have no possible way of translating our thoughts to them. Their way of life would probably be so unimaginably different compared to ours that we wouldn’t even be able to comprehend it.
This is exactly how I feel. We naively place our own perception of reality on extraterrestrial life while it may actually be something we can't even comprehend
We see by absorbing photons with wavelengths between 400 and 700 nanometers (what we call color). Imagine a being that could see other photon wavelengths like radio waves or X-ray waves. The implications. And radiation is just one of many natural phenomena.
How can we plainly say mathematics is the language of the universe when humans are clearly the only species we know that use math? We cant assume that alien life form will understand math because we clearly dont even know how they’ll look. Even the most intelligent species on earth cant speak mathematically, only humans do
@@blessingnations7289 True, we are the only species that has mathematics that we know of. But it is reasonable to speculate that an intelligent species will be able to witness correlation and causation within the laws of the universe and possess their own tools for making sense of it. While the symbols, coefficients and operators would be different, the implications and applications would be universal.
There are plenty of perfectly reasonable answers to the Fermi Paradox. One is that interstellar travel may just not be possible, or at least tangible. Another is that, given the age of the the universe and even the Milkway, few if any intelligent species have co-existed at an advanced enough level of civilization that they could have ever crossed paths. Or maybe other intelligent life just couldn't be bothered to attempt interstellar travel. Just because we think it's a great idea doesn't mean everybody does. It is also possible that an intelligent species did develop interstellar travel, got close enough to earth to pick up our radio transmissions, and said, "Those people are crazy! I'm not going down there."
if there're really intelligent life forms other than us, then they probably wont just show themselves before studying us, and probably they said "nope" after studying us.
So, we have no idea what technology they would be using for faster than light travel. It's likely a limited resource. It could be as simple as not having enough gas in the tank. They could be on the other side of the milky way colonizing a dozen planets at distances apart that we can only dream about.
Imagine wanting to have an answer to the question "where are all the aliens", a decade before the first human being put in low earth orbit and half a century before the first exoplanet being confirmed to exist. And this becoming a "gospel" for mainstream science, while we still can't answer the question of "if there's alien life in our solar system". When we interpret our complete ignorance as a universal "paradox"...
You do know if we can send satellites outside the galaxy we can travel just as far if not farther. Space force isn’t new either. Chances are we’ve already made contact. Most likely decades ago.
Like Brian Cox said. Both outcomes are deeply fascinating. There is intelligent life out there somewhere or we are extremely remarkable in the sense that we are the only ones.
I always like to imagine that there is a civilization that is looking into the vast space just counting the amount of stars, planets, galaxies, exoplanets and so on, just wondering "Where is everybody", just like us and that one of the exoplanets, Earth, could have life on them. Even if they would be "just" a few light years away from us, colonizing their solar system and still not encountering anyone else just deepens the thought that they might be alone in the universe and just as special as we think we are.
There could be an entire planet with billions of "citizens" that fits in the palm of your hand, or a planet so large that earth would not even be a grain of sand in comparison 🤯
@@tomgunnz007 wow I have never thought about this considering how there’s no limit to size on a cosmic levels…the stars we call the biggest are just the biggest WE HAVE/CAN SEEN….things go get so big and still have a whole replicate that’s very microscopic… wow man you just blew my mind
@@tomgunnz007 If this were the case, and not saying it's impossible because just about anything is possible, then their physical characteristics would be vastly different from ours. Imagine a tiny Earth, it would have very little gravity and life there would either have to live underground or have a large mass in ratio to their size in order to not drift away. On the other hand, a massive earth would have huge gravity force and life would have to be very stout and strong in order to move about.
I like to imigine that we are being watched but the Aliens are just thinking "not arsed going there the people that live on that planet are just the worst"
My dad said something to me once that always stuck with me. If/when humans come into contact with intelligent alien lifeforms the timeline of human history will reflect it. Probably we won't use the terms BC and AD anymore. Maybe instead we'll use BC and AC where BC = before contact and AC = after contact.
Vesuvius, your dad was completely right ! "AC" and "BC" refer to Someone who let us a message that has been written in the Bible : Jesus Christ This message predicts "the Apocalypse" which is not the end of the World, but its ethymological meaning is "Revelation". In the end we will be facing a revelation of the truth which is not what we all think about. Just wait and see !
"Just because we find it hard to do in a laboratory, doesn't mean nature has found it hard to do as well. AND the idea that it is hard for nature to do because we haven't figured out how to do it yet is itself an inexcusable expression of human ego"
I think the fact that many creatures on earth past and present gave enough time could possibly evolve to the intelligence level of man speaks volumes to the possibility of intelligent life out there. I think we will find out that we are one of the first intelligent species in our galaxy or that space travel is only possible the slow route "sub-light speed colony ship style".
Especially if you take into account that life started on the Earth as soon as it cooled down. There is research on how life dissipates energy and thus increases entropy far better than chemical molecules, so it might be bound to happen.
We don't have to be alone to be effectively alone. Even if there is technological life on Andromeda, we would not know it with present tech, and if reality is essentially as science has currently modeled it (yes, our models are incomplete, but perhaps not drastically so), we will not likely ever know it. It's kind of depressing to think that FTL travel might actually be impossible, but it could also be reality.
True. But I think they've intervened in human civilization for millennia and continue to be involved. Sumerian, Egyptian and Babylonian tablets show and describe gifts, intelligence, knowledge and language passed down from the Gods to mankind. Pretty confident all these Gods, angels, demons, "beings from the heavens" were misinterpretations by very primitive and ignorant early humans.
Maybe intelligence is “the great filter”. Think of all the species that survived longest here on earth.Cockroaches, crocodiles, sharks,insects…..”maybe intelligence is just the thing you need to render a species extinct”. Makes you think .
You've never been in the ocean or watched a fly spider for very long if you think these things arent intelligent. If the goal of life is survival, I'd say they are the most intelligent species.
I think its because those lifeforms live along in balance with nature while intelligence has caused humans to leave natures balance and in fact throw it into chaos.
I know life as we know it needs water. But I'm 100% convinced there are all kinds of life we could never comprehend! Everything in the universe shares this extraordinary gift of being born. Growing old and dying. Even planets and the sun's do this. Planet's and Sun's are born, and they get old, and they die. Heck, even galaxies do this. We know so very little of what is really going on in the universe. Its just so big for us to ever comprehend. Will we learn more as we all die and pass on? All we can do is understand our planet and the creatures on Earth. Any scientist who tells you there's nothing living inside Jupiter is flat out lying to you. They have no idea what can be created outside of what is too far beyond their reach.
@@lagodifuoco313 i really wish some civilization figures out Interstellar travel but the scale of the universe, the distances and such make me believe otherwise.

It’s actually statistically impossible by all reasonable notions that we are alone in the universe, now contacting and living with Sentient Xeno life would be impossible within a generation for us unless drastically advanced jumps in our technology were made and I say drastic by means of we can freely travel between stars in weeks to a month at a minimum depending on distance. This is currently not feasible but still a good dream to strive for, however if there is intelligent life out there and it is not on one of the moons of Jupiter or on Mars we will never see any true intelligent alien life within at least the next 4-5 Generations and that’s with rapid Technological advancements. Remember not all infinities are the same but we can’t see it all anyways let’s seek out what’s most likely in the endlessly recycling Void.
The two questions I always go back to regarding this is 1) is technology capable of allowing humans or a human-like species to colonize interstellar space even possible? Lightspeed in the real world isn't as "fast' as it is in Star Wars. 2) Is that level of technological advancement before or after the 'Great Filter'?
Current technology? no, current theoretical technology? no, can this change within 5 years? of course. As long as we keep advancing we'll find solutions... Stagnation or maddness is what will destroy us.
@@charlie-obrien The mast and sail was possible without breaking the laws of physics. So was getting to the moon. Getting across the galaxy within a human lifetime...that's going to take technology that is as advanced to us as our rockets would be to the generation of humans that invented the mast and sail.
@@bchristian85 You missed my point... No one could imagine the mast and sail, until one day they did. Until then it was a completely unthought and impossibly foreign idea And it wasn't just one localized discovery. It happened in several places all over the world during different eras of history. Your comment shows that kind of thinking because you mention our known physics as holding the answer, when it is also something that will come from a completely new vision of how that type of travel or transition could happen.
In cosmic scale, we have been here for 1 second. To "find" other intelligent life forms by observing the sky with our current technology, they would need to be in the exact correct location within that second. And we can only see our galaxy, and only small parts of it. The Universe is too big for us right now to observe. Let's see a thousand years from now how far we are then.
Naw, radio waves exist and if there are other sentient species out there, they SHOULD be emitting those radio waves which we can detect. The absence of those radio waves, even from past dead civilizations suggest that either there is no intelligent life, or that if it does exist, it doesn't get passed a certain point before going extinct.
@@beezusHrist Radio waves become background noise after certain distance and we can no longer detect them. You completely fail to understand the scale of the Universe. Our own radio waves in the 100 or so years haven't gone even 1% through our own Galaxy, and there are at least 100 billion of Galaxies in the Universe. Anything coming from another Galaxy gets lost among the background noise of the Universe. Also, intelligent life isn't just life which sends radio waves. There is definitely intelligent life out there, everywhere.
@@MegaPieru3000 And we are talking about the type of intelligent life that can send out radio waves and your point about radio waves proves my point exactly. Just because those radio waves become indistinguishable (not undetectable) from CBR after a certain amount of time, does not mean intelligent species, like our own, are not able to extract meaningful information from CBR especially if those intelligent species have the right equipment and know how that can extract such data, and as of now, we have the equipment to extract meaningful data from CBR if we recognize abnormalities. From what we've seen so far, there have been no abnormal CBR readings we can further extrapolate information from. Now as for intelligent life being out there who can't contact us, who cares. They, like us, are on a timescale toward extinction and if they do not find a way off of their respective planets before they go extinct, does it really matter (to us) if they ever existed at all? Not to me. I only care about sentient life that we may someday be able to contact. Not in my lifetime of course, but someday. I also care about humans being around long enough to make the technological progress to be able to contact such life. And Radio waves move at the speed of light so we've been broadcasting for more than 100 years which means our broadcasts have spread out in all directions going the speed of light. Are there habitable planets 100 light years away from us? Why yes there are, so where are all the aliens? Probably dead due to climate change and climate devastation. But, only time will tell. Maybe after going the speed of light for 200 years we will finally make contact with a sentient species. Who knows.
@@beezusHrist We can't detect anything that has gotten lost among the background noise. Most certainly not deliberate messages. Our technology isn't there yet. Our own galaxy is 100,000+ light years wide, so 100 light years is nothing. And of course, there's the time needed for any close detectable messages to come back from them.
@John Barber lol , I agree our intelligence is so misdirected and destructively utilized hastening our extinction . Despite being at the top of the pecking order ,our intelligence still has much to be desired, unable to evolve because of very short lifespan . If the death sentence of aging is conquered maybe our intelligence will find know no bounds.
Dr. Tyson, like so many contemporary scientists, tremendously confident in knowing what is unknowable presently. This is the intersection of philosophy, science and Logic. I’ve never heard, seen or read any scientist explain to me, a reasonably intelligent person with a graduate law degree [not an appeal to authority folks], how Life in general began for any organism, how the Universe began, how something can come from nothing and on and on. These questions have been pondered from time immemorial, but I’ve never heard a good answer, mostly because we humans are limited in our ability to know, but sometimes affect the contrary, if only to beg more questions. Basically, I’m content to know that I don’t know and that perhaps things may be revealed to me at some point, or not at all. But, can we just agree that as humans we cannot possibly know the presently unknowable? Any scientist who is comfortable in their knowledge of the cosmos is not a true scientist.
@Science Revolution you are so poorly misinformed I don't even know where to begin. I suggest you research quantum physics and particle physics, along with astrophysics in order to gain a realistic grasp on the subject as your understanding of it is vastly different from the scientific research.
@Science Revolution nevermind I looked at your channel, nothing but insane conspiracy theory nonsense such as 'why I know the ISS is fake' It boggles my mind that there are people that are so willfully ignorant and just choose to ignore what is plainly presented in real life for you to see for yourself. Yet people will see the ISS literally fly by overhead in the night sky...and still deny if exists....wtf.... I see no point in trying to get you to see reality and science for what it is, as your mind is already made up. Please don't spread misinformation. It is extremely destructive to our society. Good thing your subscriber count is abysmal. Good luck with whatever it is you believe you're trying to achieve I guess.

I feel like the definition of life is too old, because we know that creatures can adapt to their surroundings due to natural selection, they evolve in so many different ways depending on the surroundings and these creatures may not even survive in our planets condition and have their own necessities to live, like maybe they are in areas with constant snow. Look at viruses, some people don't consider them as living, and I understand why they would think that but they do things to keep them alive. What I am saying is life could just mean things could reproduce in any way, I know this is the most general thing but could you really expect to go to a different planet see creatures exactly like humans, pretty unlikely.
thats why i believe that aliens exist. I wrote a paper about how adaptive life on earth is, and it turns out that life on earth adapt very well in extreme conditions. Which makes me think that there is no way that life as we know it is the only life in the universe.
not really... u need to support unlikely and likely.. otherwise its I DONT KNOW... butt first we have to get past the part of if life on earth is just a utter anomaly rather then highly likely given the size of the universe.. we literally know what chemicals and reactions are need for life.. yet we still cant START A NEW LIFE.. so this begs to question .. if there are billions of earth like planets with all the same and similar chemicals reactions as such happening.. there is no evidence that whatever CAUSED life happened there too... what we're doing is 100% lookin only at life on earth with NOTHING to compare it too then projecting EARTH LIFE onto other planets in the universe.. what if earth life hypothetically is the WORST and least likely method for life ..? a freak accident that was so unlikely that it takes billions of mulitiverse just to even have a chance and we just happened to happened..? how do we know it doesnt take billions of multiverse to act on each other to create a single universe capbible of life? to me.. "the universe is so BIG there has to be life" is like saying "the universe is so BIG therefore god" its like "i dont know so therefore god" = "our math breaks down therefore infinity" yes "infinite" is what we say when MATH no longer works... and from my understanding thats HUMAN ERROR... we jst dont have the know how to solves certain issues yet so we say INFINITE..
Thank you for that lecture walkthrough. I’ve been wondering this question myself and I’ve never been able to figure it out. Nonetheless, I found this video interesting and hope to learn more.
The other thing to consider is that there may be concepts we haven't even come up with to do with issues of being an even more advanced species, limits we can't even conceptualise at this stage of our development. Thankfully there may also be solutions we cannot consider at this stage as well and therin lies the optimism. We got this far, lets see how far we can get together.
I've actually watched another video that said our position in space is actually a pretty big void, which could be the reason we don't see colonies of other species, and why they don't see us.
The thing is, we are making a lot of assumptions about aliens and their development. And currently the only example of a technological species we have is ourselves. A species on another planet may develop technology along a different path than we humans have. Depending on their own evolution, environmental factors, or perhaps even their position in the galaxy. An interesting example of an alien race is from the Andy Weir novel, Project Hail Mary, (Minor spoiler warning) there is an alien species that evolved on a world closer to their sun than ours. They have a higher gravity field, and a much denser atmosphere. So the surface of their world was pitch black and very hot. Their species did not evolve eyes, but used sound and a form of echo location. Their language was more like musical tones. Their bodies evolved on a world with a higher atmospheric pressure. So because of their planets condition, they had no concept of radiation. They had not even developed computers or radio. There had been no need to. The long and short of it is, its not that Aliens are not out there to hear our messages. We may just be sending the wrong messages. They may have no ability to hear our radio signals at all. They are not us, so assuming a similar developmental path is asinine at best.
Wow, very profound. Our environment dictates our evolution which dictates the way we interpret and experience reality via our senses which in turn dictates our technological path
Maybe the question isnt where is the all the life...maybe the question is when? We could be the first, or we could be millions of years late. They could be so many light years away that we wont even see them for several thousand or million years
Or maybe we just aren’t interesting enough for them to bother? There are a hundred ant hills in my yard, and I’ve never done anything but pass them by.
I get the feeling we are late not early. our solar system formed 7 billion years after the first stars came into existence who knows what has already happened. for all we know there have already been a galaxy spanning war 6 billion years ago where all intelligent races were exterminated.
@@ocirontariocryptidinvestig8010 actually it took many supernovae in order to produce higher elements in the Universe so no, there could be no other life 6 billion years ago because it most likely would not be able to form from hydrogen. But if the universe is older and much larger than the observable universe then it might be true.
@@ToDie4r I would have assumed that elements would degrade in number as stars died and were reformed into new solar systems. I don't really believe we have the ability to know what was contained within stars across this galaxy 5-10 billion years ago.
@@ocirontariocryptidinvestig8010 that is a fact, with respect to standard model and Big Bang. It's necessary for a star to be enormously big in order to make enough pressure and heat at it's core to make higher elements. Especially gold for which i think it's produced only in supernova explosions, as every higher element. That's just the way physics is my friend :) Follow Dr. Physics on youtube he has wonderful content. Best regards.
I think life as we know it is probably rare when compared to how many planets and star systems there are. If we’re looking for aliens “like us” we will probably be looking for a very long time. And then you have to think about how far apart we are, separated by not just space but time as well. We would have to literally stumble across aliens in a moment of sheer blind luck. The universe is an absolutely huge place.
How about this... We Are Not Alone, We've Never Been Alone. The rest of the universe has had a multi-million year head start on Earth. Earth and humanity is EXTREMELY late to the game - ok. Aliens and more correctly put, Advanced Beings, have been visiting this Earth for many millennia. and aiding humanity on multiple levels throughout our civilization. The saying goes "If you want to believe, the truth is out there. If you don't believe, no amount of actual evidence will ever suffice." HTH
Here's how I think of it: Imagine if we take Earth, flatten it out and stretch it proportionately to the size of the observable universe. Now consider how far apart you would be from the closest person you are nearest to now.
We think that our world is huge, but we seem to forget that the Earth is just a tiny speck in comparison to this galaxy, and this galaxy is just a speck in the universe. Even if there were another civilization we could communicate with, I couldn't even imagine how far they could be.
@@tommiezturner6554 I'm saying even if there are as many living organisms in the universe as there are people on Earth, the likelihood that any one of them would be remotely close enough to us to find, much less communicate with, is so close to zero, it might as well be zero.
One of the more likely answers is that we are one of the early first wave of advance species thus why we have yet to meet any other life as they are at a similar stage as us. The second is that advanced life likely does not wish to make it self known to us and let us advance naturally to a point. Think of it is like the prime directive from star trek.
it may be the case that industrialized civilizations only rise in a third generation solar sytems. As you would not have large deposits of iron on first or second generation stars.
or, FTL is simply not possible, so they couldn't even visit us even if they wanted to...of course, interstellar communication is still possible, but we need to talk the same "language".
Fuck all y'all, In the beginning God created. The end. Makes me wonder, if space is infinite, does that mean God is still creating shit and will need to forever since space has no end?
Life is infinite. Imagine all those realities. It's endless. Enjoy the journey. We create all of this plus more. Imagination is everything. Truly. Love and Light
Dr. David Kipping on the Cool Worlds YT channel is good too. Talks about the rare Earth theory and how earth like planets with complex life may be the exception not the rule.
Vast, mind boggling cosmic distances between worlds is what keeps us from finding anything. Advanced alien civilizations may have technology to overcome these distances, but they would be so advanced that we could not yet comprehend their technology.
@@ANTIStraussian Or they may be at places like S4, Most people just laugh at very credible vetted military personnel who try to relay their eyewitness accounts.

"Intelligence is just the right thing to have to render yourself extinct." Wow, that's a depressing notion, but seems likely true. It's probably not intelligence itself, but it's the transition between low intelligence to high intelligence. A civilization has to cross that precarious void of learning how to harness vast amounts of energy, AI, nanotechnology, etc. without destroying itself or overconsuming resources. It's a pretty good possible answer to the Fermi Paradox: it's just extremely hard to stay alive for very long in this universe.
8:31 "Inteligence is just the right thing to have to render yourself extinct." ..... I have never thought of it like this and it amazes me how true it actually is.
I'd just like to say the visuals in your video are immensely satisfying to the eye. I'm curious, do you have your own graphics department, do you outsource the visuals, do you use royalty-free graphics?
Given how we haven't really been able to get very detailed information outside of our own solar system, it's probably just a matter of we're too primitive to find intelligent life. And given how we're fast-tracking our own extinction, it looks like intelligence didn't really do too much for us.
Given how knowledge is a self-propagating and exponential process, there is unfortunately no particular reason to believe that any other intelligent species early in its evolution would find themselves in a significantly different position than we face now. Any one of them would almost certainly face a point where they learned to split and fuse atoms, and develop industries and technologies that they understood poorly and used unwisely. Right now technology itself looks like the most dangerous Great Filter to any intelligent species.
We have had some rough patches. We will have more. However, we are still here. Still learning. Still expanding. Our first radio signals, by now, and crossed 10s of thousands of planets and it is still going. A bit of faith and even more patience. We'll get there. If the phrase about "if you tell me you dont think you can do something or you tell me you cant - they are both right. (it is something along those lines) If we focus on self destruction, we might have to prove ourselves right. Better to not go that route.
NdGT said something brilliant years ago, it was something along the lines of intelligence is not a requirement for life. Even if life does have intelligence, like humans, look at how they squander it away.

I sent this to SETI: I realize that folks in the science community don't like suggestions but I feel like this one is super pertinent to SETI's plight. So please hear me out, it's short. Sure communication through space is seemingly unobstructed when you think about objects near/within our solar system, but I'd argue the effects from orbiting bodies, scintillation, and the inverse square law will not allow signal acquisition from entities light years away. And thus Fermi's Paradox is flawed because it assumes specifically the acquisition of signals from distant orbiting bodies. Any where past light days, the signal is spread out through the cosmos instead of being tightly packed which all but ensures the data can never be decompiled/processed. At first I thought the issue for the broadcasting entity could be remedied by utilizing a spacecraft and performing a Homan transfer to align your velocity vector with the target planet. But I fear that alone won't be enough to mitigate the sun's gravitational effects (on the signal), even with the Delta-V. Instead I suggest that if you want to transmit a signal to a solar system light years away you need to have the spacecraft Homan transfer to the velocity vector of our sun targeted on a system in that direction. Then radiate our loudest/powerful signal. In addition I believe scintillation effects are too compounded if the transmitting entity is targeting a solar system that is edge on to us. So I believe you must target solar systems that are aligned with our celestial plane. Further, I believe that if you want to listen, you'd point your antennas to star systems in the neg in-track of the sun. And once again those systems should be aligned with our orbital plane. Talking to Voyager is not easy and that signal and our ground systems that acquire it are dealing with very low signal strengths and super high signal to noise ratios. And that's just 5 ish hours of light speed away. Instead of asking why isn't anyone broadcasting, we should ask why can't we hear them? I think this is why. I believe I've laid out a good angle for a revitalized concept of operations for you all. I hope you all pass this along to the proper folks. I believe it's imperative. Ty ty for all y'all's hard work! The work you all do is extremely important to humanity.
@@outtaideas6974 overpopulation is not a problem with the earth right now, infact it's actually decreasing. The problem with earth right now is that we can't get along. That's the main problem. All others would likely be solved if we worked in harmony. Edit: Birthrate is decreasing not population
@@anthonyw9129 I totally agree with you. I lost all respect for Neil after seeing an in-studio interview where he tells a news team, in regards to the then-recent release of the Navy UFO videos, after being asked "what are they??" he responds, "I don't care what they are - they're UFO's". Seriously?? A "scientist", upon learning that the military freely admits that real, solid objects are flying circles around, and are the size of, our fastest fighter jets, can go from outer space to a foot above the ocean in less than a second, then into the ocean without a splash, where there is radar, infrared, satellite, sonar, visual contact and other telemetry, yet he has absolutely no interest as to what they are??? I call BS. Either he knows something already, or he's a fool and should renounce his credentials as a scientist of anything.
3.5billion years is still about 1/4 of our universe age. It feels like our universe is actually pretty young because that must include the time it takes for planets to cool down and be ready to have life.. I think it is very legitimate to think that we are some of the first apparition of intelligent life in our universe.
If aliens are well above us theyd know better than to interact with our species while we're young and undeveloped, they're also be smart to jam any sort of communication efforts coming from us to insure we don't reach out before we are ready, they could be literally watching over us like babysitters
I honestly feel like there may be a couple other planets with life but also we may be the first , and it’s our great duty to inhabit other parts of the universe so we don’t become extinct. Because as long as we can outlast we will accomplish great things
We are like a stranded crew marooned on an island, hoping for rescue and doing everything we can to get the attention of passer-by's. If we don't destroy ourselves, we will achieve amazing things. Until then, we need to keep it together.
How conceited we all are that every discovery, every scientific achievement should be in our lifetime. Dr Neil is a stalwart of our time, but who's to say a hundred years henceforth, all our questions are answered?
We will not get there as earthlings are too busy at destructive pursuits , also are BIODEGRADED to last that long . This racial hostility is causing DECAYED gene pool . Racism is a form of INBREEDING , preventing biodiversity. What do you think of my perspective? Lol
I always remember that all of our science, etc., is based on physics and things as understood by humans. There could be a ton of things we couldn't even comprehend because it is beyond our mental capacity. Maybe we are the aliens on the Earth.
We have examined our own physical and dna heritage and have managed to draw a pretty detailed lineage back over the course of billions of years at this point, so, no - right now we can be pretty confident that we grew up here.
@@Vastin you are thinking of humans as we are in our current form. The seeding of Earth with the building blocks of life is what would make us alien. I think the building blocks of life are common. The environment needed to support life may not be but we know for a fact that it is possible because we are here. I don't think life in general is all that rare. Intelligent life probably has occurred, exists elsewhere now, and certainly will in the infinite future.
@@marcus1282 It is certainly possible that life on Earth was initially seeded from a non-terrestrial source, or influenced by one if it were early enough to do so before we could really detect those change in the fossil record - but if that's the case, that 'extra-terrestrial' life would have been here for literally billions of years - not really even legitimate to call it 'alien' at that point. The distinction would be essentially meaningless, it would still just be 'life as we know it' in any meaningful sense of the term.
@@Vastin I don't really see it that way. It doesn't matter if it were yesterday or 4 billion years ago. If true, it would be important to understand. People want to know what circumstances started life here as it may help us better understand where it may be elsewhere. Of course, if true it doesn't mean that our circumstances have to be present in the exact same way elsewhere for life to occur. There may be infinite possibilities and I suppose that is what makes thinking about all of this so much fun!
No. It shows you don't understand.. There is a reason that math is a universal language. We use certain symbols to communicate. The phenomenon those symbols represent are fact. For instance, if you use the law of identity, something is what it is and never what it is not. A rock is a rock and never not a rock. Even if you don't use the label rock. Physics is the same. Doesn't matter what we use, the phenomenon is apart of reality. An advanced species would understand math 1+1=2. Period.
Rather than looking for a job, This is my very important subject for me as a 3D designer “from symbolic to complex “ and I think I go the structure that’s connecting every mesh in models as “tree leaf logo”! Gravitationall wave function!
Something I don’t understand is if it’s true that life got going relatively quickly and easily in the Earths life then shouldn’t we expect to see it happening more than once, with several separate trees of life with their own independent genetic lineage rather than the single one we have?
Maybe very, very early on there might have been several false starts, or attempts at different types of self replicating chemical processes that might have competed with each other for a time - but its likely during the very primitive era that only a few approaches were remotely viable, and that number probably got whittled down to one - which would have been the ultimate pre-cellular ancestor of what become the RNA/DNA strands at the core of all living things on Earth today. Once those early protein strands managed to become decently established and began to develop and diversify, its unlikely that any other new process would be able to competitively establish itself in the tide-pools and chemical morass of the early environment on Earth, locking the biosphere into a single general course for a long time until these little guys became robust enough to develop into more and more specialized environments, becoming the general branches of life that we recognize today.
We might be the last intelligence that we've been looking for, that's why its taking like forever for us to find new life somewhere in the cosmic. And in my opinion the signals that we received, just arrive in our direction after a thousand of years that passed.
Very interesting, I would say that that due to the sheer size of space (endless) that we are simply hidden within the universe from other forms of intelligent life. (Toothpick in a haystack)
But intelligent life is rare. Neil said it himself. Millions of species on earth in the last 4 billion years have developed eyes, and mouths, and ears, and hair, etc.. But in 4 billion years, on a planet thats abundant with life, intelligence has happened only once.Thats proof beyond all doubt that intelligent life is extremely rare and possibly even unique to us.
@@joshualee7709 just my humble opinion but maybe intelligence has happened, but it has never passed further. Perhaps this is the edge. Any further and its only void. We built things and put them in space but our progress is minuscule compared to the unfathomable expanse of the universe. Just like someone said, " we're just a grain of sand in the sahara desert ". Just my morbid prediction but once the james webb space telescope launched, if it cannot detect something awe-inspiring like an actual civilization in its images then human intelligence will have little to look forward to. After that, there will only be squabbles and quarrels happening in earth. To rephrase life will be cold and bare, just waiting for the inevitable.
@@jadedjay7861 I highly doubt that. I think that if anything, we MAY be seeing unmanned probes from other civilizations launched hundreds or thousands of years ago. Much like how we send out probes but on a bigger scale. That said, I doubt even that.
@Jayo Delaware *fun opinion. With all current acquired knowledge of the universe we have, we still can’t prove or disprove there being intelligent life elsewhere. Only theories..
@@lonki369 but we could of popped up from the most rarest of circumstances. A bunch of events leading to things leading to us. We don’t know how common or rare life is in the universe
@@ryure4268 i believe in the evolution so for me we didnt just pop up, and you know there is trilion and billion of planets in the universe so i know there is a huge possibility of life, but maybe not intelligent
Maybe this is a strange thing to think about but I love the idea that maybe one day we can make contact with an alien civilization and learn their language and be able to communicate with them and make some alien friends. And maybe they can in turn learn some of our Human languages. Maybe it's because already as it is, I have a huge fascination with learning other languages than my own, and the idea of communication and talking to people in general. I feel like it would be so cool to learn another life form's language. Who knows maybe there's an alien civilization out there that's like us humans here on Earth, where they have different languages and appearances and cultures depending on the region of their planet they were raised. I think it would also be cool to use slang in an alien language. It already can be difficult learning a new language, let alone learning the proper way of speaking it vs the more common slang used by native speakers especially the youth. It does make me a bit sad to know other life forms may be avoiding us if they are out there and know of us, but I don't blame them either. All though we have so many amazing people on our planet, the way our species tends to behave, we can pose a potential threat, and on the chance they've raised beyond that, they probably don't want to start some kind of unnecessary war. So maybe it's for the best we never make contact with other life forms. Our species tends to take anything foreign or unexplainable as a threat, and it would be very likely for us to attack, causing mass destruction and a shit ton of suffering, on our side and their side. I wish this wasn't the case, because imagine all the nice and wonderful people you could meet. You could hear stories from them about what their home planet is like and where they grew up. Maybe learn about the types of plants they have, animals, the weather. Maybe their days and nights are far different from hours. Like for example, maybe a day could be like 48 hours for them on their planet or maybe even a bit longer. I wonder what their homes would look like and if they have forms of education and places like schools to serve the education. Who knows maybe they'll be nothing like us in anyway. And maybe that's what truly keeps them far, far away from us. Because we're so different and unpredictable that they don't even want to risk trusting us. But again, I don't blame them. I would be afraid at first if aliens came into contact with us too, even though it is very cool in retrospect.
And don't forget: We have sampled TWO planets for life and have found evidence for life on BOTH of them (Earth and Mars) SO far the chance of life on a planet is 100% according to our sampling. AND we have discovered THOUSANDS of extra-solar planets. It would be illogical to assume no life on them.
@@AFreeThinkingDawg09 I was thinking more in the present and accounted for sense. Yeah, we've sent probes further. But really, we've only done the equivalent of leave the house and walk to the sidewide and peak down the street.
@@littlebabyhoho6750we haven’t even made it out of the house yet much less the sidewalk, AND all the lights are off so we’re feeling our way around the dark for the light switch still.

A very aggressive mouse lol
Or maybe they're all miniaturized cybernetic life forms who've learned to live so efficiently and have so much going on in their virtual realm that they've lost all motivation to care about the physical realm.
That almost sounds like some of my friends. Cybernetic. They live through their Phone and computer. Live efficient. They have an income without doing almost nothing and they get food etc. They live in a virtual realm. They live 85% in their games, and 15% in the real world.🤣
It certainly seems to be one of the more realistic solutions to the Fermi Paradox - and the lightspeed barrier. Our current physics strongly hint that it's much easier and more efficient to build *inwards* than *outwards* in terms of increasing the scope and scale of our civilization.
If the closest extraterestrial civilisation able to radio transmissions is just 300 parsecs away and is transmitting for 2 centuries we need more then a century from NOW till we pick something up...
300 parsecs = 978LY. Assuming a transmission lifetime of 200 years, that would correlate to a 400LY radius with the transmission energy decreasing by a factor of 4 as the distance is doubled according to the inverse square law. So you would need at least another 275 years to listen.
Sometimes, you have to go beyond knowing everything and know nothing to find what you are looking for. There are riddles in your own backyard that are avoided (publicly) that will lead you to your answers. Somethings are stranger than fiction and the ones who continue with the strange will find life beyond what you "know". Be brave.
@@_Breakdown That humans are originally freeform Light Beings that are stuck in a gateway. Earth is a petrified gateway. We are time travelers that have forgotten our way home after thousands of years trapped here.

To young to explore the world to old to explore the stars this is a reality I’ve been struggling with for sometime I hope my children or grandchildren will know the answer
You know what surprises me is the fact that we have this life long question about how we are alone in the universe or not. I think the fact that we even believe that we are alone in the universe is the most arrogant statement an intelligent species could possible say because the universe is vast and even if a intelligent species had the ability to travel through space faster than the speed of light which is nessary to get anywhere in the universe in a reasonable time period. what makes you think that they would seek us out we have only been technologically advanced for the last 100 to 200 years on the human time scale and even then we have barely scratched the surface of interstellar technology so do I think life is out there yes absolutely but do I think it's likely we will ever find other intelligent life not so much.
It's almost like its anti-arrogance. When people ask 'Where are all the aliens? ', I just think... look at the popular culture, it's corny but think about it... crop circles, stealing cows, kidnapping people, experiments... I ask "Why haven't we been doing that?" Going to other planets, stealing THEIR cows, kidnapping THEIR people... drawing crop circles on THEIR land... It's because we don't have the technology. If WE don't, what makes us think that THEY do? They're likely trapped on their worlds just like we are on ours. It's super-arrogant to think we're the pinnacle of life in the cosmos, but it's anti-arrogant to think if there IS other life, they are all more superior than us.
@@gettps very true a fact that most people don't know is that traveling at light speed is not only not possible currently but its not even efficient enough to be Plausible for space travel so unless we find how to use worm holes which unlikely that they even exist we will permanently be stuck and limited to our own solar system.

To get technological intelligence your animal must have 3 characteristics: 1) A need for fire and the ability to make and control it, for without fire you cannot manipulate materials. 2) Be a social creature, not solitary, since no individual can develop technology on their own. 3) A sufficiently long life span to develop skills and pass them on Take the octopus. A good candidate for intelligence. It demonstrates complex thinking and has the dexterity to make tools. However, they live in water so will never need nor make fire. They are solitary, so do not share and pass on knowledge. They live for only a few years so only have time to reproduce and die, no time to tinker. I suspect that getting life that has those three characteristics, and then develops them to high levels without destroying their selves, is extremely rare in the universe.
It’s a possibility that aliens don’t have the technology for interstellar travel because it’s simply impossible. Imagine the power source needed to move solid matter at relativistic speeds. What happens if you hit a speck of space dust traveling at 99% of light speed? Maybe it’s just not possible.
We observe MANY things in the universe that are "Impossible" according to current physics. FTL will be possible. Thinking it is NOT possible while we are literally in the infancy of "Technology" is being arrogant.
@@stuartgray5877 we would need *at least* one Dyson sphere to even search our galaxy. So several to explore galaxies. It would require the power of a Dyson sphere to even create one. So interstellar travel is essentially impossible. Check out kurzegsagt (sp?lul) they've got lots of cool space vids
It is interesting to note that there is no record or evidence of more than one occurrence of the origin of life on earth. If it is so probable, why is this? Did life only arise once under these supposedly ideal conditions?
The planets in our solar system were formed by the same clusters of space debris so given the right habitat conditions the chance of finding evidence of life somewhere in the milky way is probably very likely. Also early mars was very similar to earth. If life was able to develop in the first 200 million habital years on Earth then there is a good chance the same thing happened on mars and/or any other habital place in the milky way.
@@rileyxbell our likelihood of finding any life is slim to none. The universe is just far too vast. Our electromagnetic and radio signal frequencies have reached about 200-240 light years in all directions after transmitting for 126 years. If we continued transmitting for the next 10,000 years we would only reach 1/5 of 1/2 the Milky Way. Then we would have to wait for them to transmit back. It’s incredibly likely we will never find life outside of our own planet
@@rileyxbell trying to find living, intelligent life in just our galaxy alone would be like trying to find one special ant on the all of earth. Nearly impossible and that’s just our galaxy.
Assuming we are not alone, we have two insurmountable obstacles to overcome before we can make contact: 1) the sheer, unimaginable distance and 2) time, because we are but a blip in history. Give or take a million years makes a big difference as to whether we observe life on another planet, even if it's next door - we could either be early or late in our observations and the chances of us coexisting with alien life that we can actually reach is really zero (this is often confused with the concept that there is/was/will be a high probably of alien life out there, which I'm not disputing). We may one day have to accept that we are, for practical purposes at least, alone.
Maybe it is just a very specific human trait to feel the need to shout out our existence to the universe. The majority of other species might just favor silence and hiding. Camouflage is very common among various species on our planet.
This is really smart and true. Well said!
if you always camouflage there is resources of knowledge and other resources that you cannot obtain and after a while you will be behind the others so you have to take the risk to see what others are up to do
Hiding from who?? May be technologically sound species would be well aware of the consequences of confrontations with one another.

@@BadBoyofScience tbh seeing earth, technologically speaking, is going to be really hard - they basically have to be within 100 light years of us, or it might as well be looking at us during the dark ages.
however, if they can keep an eye on our star, they could potentially tell that there's oxyen in the air when the earth is between our star and them - and oxygen in the air, given how reactive it is, means there's something there generating said oxygen.
@@leeman27534 Yep - but they have to be looking for us. They have to have the right alignment with respect to us. They have to have the correct technology to see us and we have to have not wiped ourselves out by then ;)

Yes the universe does not produce one singular example of anything.
What we consider intelligence can be equivalent to what an alien species would consider to be a sensory characteristic like sight. Their intelligence could be unfathomable to us.
Still intelligence, an organism capable of processing, storing and analizing a large number of sensory imputs beyond instinct behavior, I know that is a very large gap from an ant but still recognizable. I don´t believe in that analogy of humans beeing like ants to aliens, we don´t feel the same way about ants than dogs or dolphins, or monkeys. And we don´t treat them the same. Buuuut.... when you think of clashing cultures you could be more scared of Aliens thinking of humans as dogs than ants, you barely notice ants, and they live better that way! hahahahah :P
@@oraculox I agree with what you are saying, let's take it a step farther, compare the technology we have in 2021 and compare it to the technology we had in 1971 (that is 50 years' time) which is NOTHING compared to human history. If you travel back in time to 1971 with an iPhone and walked into NASA their heads would explode. So imagine an Alien civilization that might be 500-1,000 years ahead of us in technology to them we would seem like toddlers playing with leggos. The history here on Earth has shown us that every time an "Advanced Civilization" has encountered a less advanced civilization it has not turned out good for the less advanced civilization.
Europeans coming to North America, the Spanish going to South America, The Romans moving throughout Europe, the list goes on and on. Intelligence might be our undoing because we might actually use our technology to reveal our location to a much more advanced civilization and they come here and do to us what more advanced civilizations do to less advanced civilizations. BAD THINGS MAN,,, BAD THINGS,,,LOL
@@tbirum Of course. But there is stagnation between leaps of evolution. On our level of cognitive response and reasoning is kind of fair to say we won´t have another leap for quite some time.

In that valley of "need" we could see an evolution of the brain, or watch entropy at it´s best hhahhah
for all we know, a type 2 or 3 civilization could already be analyzing us lol
That’s as inaccurate as the Drake equation. Intelligence means what it means. Ability to advance throughout the lifespan of the species. A monkey gets lucky and uses a stick to do some things but isn’t intelligent enough to pick out a good stick and work it and keep it for that task

That's because it's not a paradox. Threw me too.
It should be called Fermi's quip, since he was just joking.
A paradox is two logical statements that contradict each other. This does not.
@@-Subtle- I thought it was called a paradox because we don’t see any aliens or life any where else but the evidence says that there should be life other than us.
Just mathematically there has to be a lot of intelligent life in the Universe. The problem is that where ever they are, they are stuck where they are at just like us. The tremendous challenges of long duration space travel are too prohibitive to overcome. Biological life forms are too fragile for long duration space travel.
Depends on their history. You take away things from ours like the fall of Rome and we might have already colonized Mars.
Why does it have to be long duration? Traveling at near light speed would seem to be a short trip to the person making it, and we already know of one way to bypass the light speed barrier that isn't in violation of the laws of physics as we understand them. Who's to say that another species hasn't cracked the how of doing it, or have some other science we simply haven't discovered yet. For all of our advances, there is still so much we don't yet understand.
@@JoeSilverhand The reason it has to be long duration is the distance to the nearest star. Even at the speed of light it would take years to get there. If you are traveling to a star system that is 100 light years away, that is 100 years of travel. The propulsion system and fuel required are just the fist extreme challenge to overcome. Please share with NASA your solutions to Interplanetary, Interstellar and Intergalactic travel. They will hire you and pay extremely well.
@Pony Package OK
That point of view assumes human biological issues and societal issues when postulating the idea of deep space travel.
The fact that we haven’t yet discovered life speaks to how small and isolated we are and how big our universe and space is. Surely other life exists but the sheer size of the “playing field “ is incomprehensible.

I think we're surrounded by intelligent life who are having the same conversation.
They know we're out there but realize they might not ever get to make contact much less visit.
I personally don't believe humans have reached the 'Great Filter' yet and there are other species out there at least as advanced as us. That said, humans will likely destroy the planet before we get to a level of technology where we could conceivably send humans to another star system. The distances in space are just that great.
Can't wait to find another intelligent alien species, and they turned out to be monotheistic, believing THEY are made in image of their God; and they declares inferior because we don't like like them(who are made at image of God), and declare every religion in Earth as pagan/heretics and they do to us the same Christians and Muslims have done to themselves in history because of holy wars.

I think the answer is that evolution of intelligent self-awareness is highly circumstantial. Prokaryotic life may exist everywhere you find liquid water. But here on Earth, three key random instances caused it to evolve further. First: The Great Oxidation event likely changed the chemical composition of Earths oceans, causing a microbial mass extinction allowing for the evolution of Eukaryotes. Second: The Cryogenian glaciation may have initiated the evolution of multicellularity. And thirdly and most notablly, the asteroid impact which wiped out the dumb Dinosaurs allowing for the proliferation of mammals that ultimately allowed us to evolve. Now consider that this random succession of important occurrences never happened on other goldilocks worlds and you have your explanation of the Fermi paradox. Earth may be an example of a relatively unique and rare phenomenon where the evolutionary dominos fell in just the right order to allow for the emergence of technological intelligence.
Or we could just be first. Earth 5 billion years old, universe 13.5 billion. We are just a baby. Maybe the universe will be filled with life when it hits 50 billion years old.
@@ANTIStraussian My suspicion is that the Universe is far larger than the portion we can observe and thus it's age is unattainable.
There's absolutely nothing to indicate that dinosaurs were any less intelligent than modern animals, that's a very common misconception. For all we know if the K-T extinction had never happened then a space faring civilization might have developed on Earth several million years earlier. It's pure speculation.
To your last point, we can never know the number of combinations of events that could occur that could cause life to form. For instance, imagine there was a dead planet orbiting a star that passed close to a black hole. The immense gravity changed the orbit of the planet into a more favorable position, and somehow kickstarted tectonic movement of the plates of the planet. This caused geological activity, which when combined with the new orbit warmed the planet enough to allow chemical compounds to form that can support silica*based life (because theoretically Carbon isn't the only elementt that can form the chemicals of a primordial soup.), And now life of an entirely different order exists from some extremely unlikely circumstances, just like ours. Considering how big the universe is and how many combinations of events can take place, it seems more an eventuality than a possibility.
I would tend to believe that the great filter is the formation of the eukaryotic cell. The circumstances of their existence are to specific and strange that it boggles the mind. According to the most widely held belief, a cell attempted to consume another cell, however the prey cell was not consumed, and instead somehow ended up both producing energy for the predator cell (forming the mitochondria) and interfacing with it's DNA in a way that caused the predator cell to build a copy of the prey cell within itself that fulfilled the same purpose. While the hand waving answer of "we're talking about a billion or more years, it was bound of happen eventually", is applicable, I counter it with the notion that in the several billion years following, it was not observed to happen again, nor anything tantamount to it. That occurrence, I believe, is about as unique as the order of a deck of cards, improbable to where it will never be seen again.
If you think there is no, or can’t be life elsewhere...in a universe tens of billions of years YOUNG, with trillions of suns, you’re a lot like flat earthers.
It's funny how we want to find alien civilizations in the universe when at the same time we can't even get along with each other in our own civilization.
i do not want to find other life, if they dislike us we are f'ed
I saw this story of an alien who really wanted to visit earth so he traveled 3.7 billion light years just to get here. And when he finally arrived, he stepped out of his craft, and the earth was basically a dystopia with no life at all. The amount of time it would take to get here is genuinely that staggering that honestly if you think abt it, it’s pretty believable.
I mean, it takes about 9.5 years to get to Pluto. And we’ve obviously been observing(somehow)planets even farther away so it’s not hard to believe that if there was anyone out there, by the time they get here, no one reading this comment would be alive to see it.
Which means we’re basically alone. And if there is other life similar to us(not fantasy aliens with super high tech) they would feel the same, alone. Bc it’s seemingly impossible to get that contact before either one of us went extinct.
Now it Kinda sounds like multiverses to me so I’m gonna stop
with infinite energy you could technically get anywhere in 5 minutes. The acceleration of an object is always proportional to the force applied to it and inversely proportional to its mass. So as long as you have energy you can accelerate infinitely. But there is a catch. No matter how fast you go, as soon as you turn on a light in front of you, it will go 300 000 km/s in front of you... and also go at 300 000km/s for an observer on your native planet. So for you it might take 5 mins, but for your people it will still take billions of years for you to take that trip.
So your story still makes sens. Not as it takes to much time for the alien to come here, but in how will the state of their own civilization will have changed by the time they come home from their trip.

We are emitting radio waves regularly since 121 years, so the radio waves must reached a diameter of a little less than 242 light years.. i really doubt that advanced aliens cannot detect primitive commucation like radio waves.

@@DarkoTrpevski or could even understand what the radio waves are even saying. They say the further the waves go out, the very little about of information is left on that radio wave.
@@grimjowjaggerjak Many of those are probably garbled by the ionosphere. Even those that aren't (like Earth-space communications), by the time they're 100 light-years away, are so attenuated and weak that they're basically undetectable anyway.
Either concept is terrifying and amazing in its own right. If the universe is infinite and we are alone then we would never have to worry about hostile alien species as well had have endless room for expansion. If we are not alone then statistically there would be both hostile and non hostile as well as inconceivably advanced and primitive species. The learning and advancement would be incredible.
Humans can barely coexist together. Aliens are our last threat to end humankind.
if it's infinite then definitely there is another life, mathematically speaking.
why would we ever conflcit with another species, for all we know they could have very different living environments (ones that would be hostile to humans). Also, there are so many planets, hundreds of which are habitable or could be made habitable (probably a lot more than that). So why would we fight if there is so much space? The more advanced a civlization becomes, the more peaceful it becomes, war was much more brutal and common 300 years ago than it is now.
We have enough with the Democrats politicians who are trying to control the planet.
If it's infinite, then it is certain that there are aliens.
I often think about if we did find extraterrestrial life, how would we communicate with them. What if we have no possible way of translating our thoughts to them. Their way of life would probably be so unimaginably different compared to ours that we wouldn’t even be able to comprehend it.
We can’t communicate with insects and we share genetic history with them. Imagine an organism that evolved outside our evolutionary tree
This is exactly how I feel. We naively place our own perception of reality on extraterrestrial life while it may actually be something we can't even comprehend
We see by absorbing photons with wavelengths between 400 and 700 nanometers (what we call color). Imagine a being that could see other photon wavelengths like radio waves or X-ray waves. The implications. And radiation is just one of many natural phenomena.
How can we plainly say mathematics is the language of the universe when humans are clearly the only species we know that use math? We cant assume that alien life form will understand math because we clearly dont even know how they’ll look. Even the most intelligent species on earth cant speak mathematically, only humans do
@@blessingnations7289 True, we are the only species that has mathematics that we know of.

@@cj5787 Well said.
@@nikmontecristo3683 Intelligence can be both.
There are plenty of perfectly reasonable answers to the Fermi Paradox. One is that interstellar travel may just not be possible, or at least tangible. Another is that, given the age of the the universe and even the Milkway, few if any intelligent species have co-existed at an advanced enough level of civilization that they could have ever crossed paths. Or maybe other intelligent life just couldn't be bothered to attempt interstellar travel. Just because we think it's a great idea doesn't mean everybody does. It is also possible that an intelligent species did develop interstellar travel, got close enough to earth to pick up our radio transmissions, and said, "Those people are crazy! I'm not going down there."
My bet is you get roughly 1 intelligent species per galactic super cluster. So with the distances involved we might as well be alone.
@@ANTIStraussian yeah. Ppl don’t understand how big (and dangerous) the universe actually is. Hmm 1 per supercluster, quite possible.
if there're really intelligent life forms other than us, then they probably wont just show themselves before studying us, and probably they said "nope" after studying us.
So, we have no idea what technology they would be using for faster than light travel. It's likely a limited resource. It could be as simple as not having enough gas in the tank. They could be on the other side of the milky way colonizing a dozen planets at distances apart that we can only dream about.
That, or we are the first to evolve intelligence in the galaxy. Someone has to be first, I don't see why it can't be us.
Imagine wanting to have an answer to the question "where are all the aliens", a decade before the first human being put in low earth orbit and half a century before the first exoplanet being confirmed to exist.
And this becoming a "gospel" for mainstream science, while we still can't answer the question of "if there's alien life in our solar system".
When we interpret our complete ignorance as a universal "paradox"...
👽👍👍👍
You do know if we can send satellites outside the galaxy we can travel just as far if not farther. Space force isn’t new either. Chances are we’ve already made contact. Most likely decades ago.

Like Brian Cox said. Both outcomes are deeply fascinating. There is intelligent life out there somewhere or we are extremely remarkable in the sense that we are the only ones.
I always like to imagine that there is a civilization that is looking into the vast space just counting the amount of stars, planets, galaxies, exoplanets and so on, just wondering "Where is everybody", just like us and that one of the exoplanets, Earth, could have life on them. Even if they would be "just" a few light years away from us, colonizing their solar system and still not encountering anyone else just deepens the thought that they might be alone in the universe and just as special as we think we are.

@@tomgunnz007 If this were the case, and not saying it's impossible because just about anything is possible, then their physical characteristics would be vastly different from ours.

On the other hand, a massive earth would have huge gravity force and life would have to be very stout and strong in order to move about.

"Just because we find it hard to do in a laboratory, doesn't mean nature has found it hard to do as well. AND the idea that it is hard for nature to do because we haven't figured out how to do it yet is itself an inexcusable expression of human ego"
I think the fact that many creatures on earth past and present gave enough time could possibly evolve to the intelligence level of man speaks volumes to the possibility of intelligent life out there. I think we will find out that we are one of the first intelligent species in our galaxy or that space travel is only possible the slow route "sub-light speed colony ship style".
The universe is like an ocean, it’s teaming with life, just because we’re so primitive with our technology doesn’t mean we’re alone

Especially if you take into account that life started on the Earth as soon as it cooled down. There is research on how life dissipates energy and thus increases entropy far better than chemical molecules, so it might be bound to happen.
We don't have to be alone to be effectively alone. Even if there is technological life on Andromeda, we would not know it with present tech, and if reality is essentially as science has currently modeled it (yes, our models are incomplete, but perhaps not drastically so), we will not likely ever know it. It's kind of depressing to think that FTL travel might actually be impossible, but it could also be reality.
Ridiculous. You have absolutely zero evidence. Your belief is nothing more than a religion.
True. But I think they've intervened in human civilization for millennia and continue to be involved. Sumerian, Egyptian and Babylonian tablets show and describe gifts, intelligence, knowledge and language passed down from the Gods to mankind. Pretty confident all these Gods, angels, demons, "beings from the heavens" were misinterpretations by very primitive and ignorant early humans.

It’s actually statistically impossible by all reasonable notions that we are alone in the universe, now contacting and living with Sentient Xeno life would be impossible within a generation for us unless drastically advanced jumps in our technology were made and I say drastic by means of we can freely travel between stars in weeks to a month at a minimum depending on distance. This is currently not feasible but still a good dream to strive for, however if there is intelligent life out there and it is not on one of the moons of Jupiter or on Mars we will never see any true intelligent alien life within at least the next 4-5 Generations and that’s with rapid Technological advancements.
Remember not all infinities are the same but we can’t see it all anyways let’s seek out what’s most likely in the endlessly recycling Void.
The two questions I always go back to regarding this is 1) is technology capable of allowing humans or a human-like species to colonize interstellar space even possible? Lightspeed in the real world isn't as "fast' as it is in Star Wars. 2) Is that level of technological advancement before or after the 'Great Filter'?
Current technology? no, current theoretical technology? no, can this change within 5 years? of course. As long as we keep advancing we'll find solutions... Stagnation or maddness is what will destroy us.

Your comment shows that kind of thinking because you mention our known physics as holding the answer, when it is also something that will come from a completely new vision of how that type of travel or transition could happen.
In cosmic scale, we have been here for 1 second. To "find" other intelligent life forms by observing the sky with our current technology, they would need to be in the exact correct location within that second. And we can only see our galaxy, and only small parts of it. The Universe is too big for us right now to observe. Let's see a thousand years from now how far we are then.
Naw, radio waves exist and if there are other sentient species out there, they SHOULD be emitting those radio waves which we can detect. The absence of those radio waves, even from past dead civilizations suggest that either there is no intelligent life, or that if it does exist, it doesn't get passed a certain point before going extinct.
@@beezusHrist Radio waves become background noise after certain distance and we can no longer detect them. You completely fail to understand the scale of the Universe.

Just because those radio waves become indistinguishable (not undetectable) from CBR after a certain amount of time, does not mean intelligent species, like our own, are not able to extract meaningful information from CBR especially if those intelligent species have the right equipment and know how that can extract such data, and as of now, we have the equipment to extract meaningful data from CBR if we recognize abnormalities. From what we've seen so far, there have been no abnormal CBR readings we can further extrapolate information from.
Now as for intelligent life being out there who can't contact us, who cares. They, like us, are on a timescale toward extinction and if they do not find a way off of their respective planets before they go extinct, does it really matter (to us) if they ever existed at all? Not to me. I only care about sentient life that we may someday be able to contact. Not in my lifetime of course, but someday. I also care about humans being around long enough to make the technological progress to be able to contact such life.
And Radio waves move at the speed of light so we've been broadcasting for more than 100 years which means our broadcasts have spread out in all directions going the speed of light. Are there habitable planets 100 light years away from us? Why yes there are, so where are all the aliens? Probably dead due to climate change and climate devastation. But, only time will tell. Maybe after going the speed of light for 200 years we will finally make contact with a sentient species. Who knows.
@@beezusHrist We can't detect anything that has gotten lost among the background noise. Most certainly not deliberate messages. Our technology isn't there yet. Our own galaxy is 100,000+ light years wide, so 100 light years is nothing. And of course, there's the time needed for any close detectable messages to come back from them.
@John Barber lol , I agree our intelligence is so misdirected and destructively utilized hastening our extinction . Despite being at the top of the pecking order ,our intelligence still has much to be desired, unable to evolve because of very short lifespan . If the death sentence of aging is conquered maybe our intelligence will find know no bounds.
Dr. Tyson, like so many contemporary scientists, tremendously confident in knowing what is unknowable presently. This is the intersection of philosophy, science and Logic. I’ve never heard, seen or read any scientist explain to me, a reasonably intelligent person with a graduate law degree [not an appeal to authority folks], how Life in general began for any organism, how the Universe began, how something can come from nothing and on and on. These questions have been pondered from time immemorial, but I’ve never heard a good answer, mostly because we humans are limited in our ability to know, but sometimes affect the contrary, if only to beg more questions. Basically, I’m content to know that I don’t know and that perhaps things may be revealed to me at some point, or not at all. But, can we just agree that as humans we cannot possibly know the presently unknowable? Any scientist who is comfortable in their knowledge of the cosmos is not a true scientist.

@Science Revolution you are so poorly misinformed I don't even know where to begin. I suggest you research quantum physics and particle physics, along with astrophysics in order to gain a realistic grasp on the subject as your understanding of it is vastly different from the scientific research.
@Science Revolution nevermind I looked at your channel, nothing but insane conspiracy theory nonsense such as 'why I know the ISS is fake'
It boggles my mind that there are people that are so willfully ignorant and just choose to ignore what is plainly presented in real life for you to see for yourself.
Yet people will see the ISS literally fly by overhead in the night sky...and still deny if exists....wtf....
I see no point in trying to get you to see reality and science for what it is, as your mind is already made up. Please don't spread misinformation. It is extremely destructive to our society.
Good thing your subscriber count is abysmal. Good luck with whatever it is you believe you're trying to achieve I guess.
@Science Revolution lmfao you gotta be a troll account, your theories are laughably just waay out there and people's responses on your videos are absolute gold. Everyone calls you out on your bullshit and you still delude yourself. You need help my dude.
I feel like the definition of life is too old, because we know that creatures can adapt to their surroundings due to natural selection, they evolve in so many different ways depending on the surroundings and these creatures may not even survive in our planets condition and have their own necessities to live, like maybe they are in areas with constant snow. Look at viruses, some people don't consider them as living, and I understand why they would think that but they do things to keep them alive. What I am saying is life could just mean things could reproduce in any way, I know this is the most general thing but could you really expect to go to a different planet see creatures exactly like humans, pretty unlikely.
👽👍👍
Remember that clay crystals do that.
thats why i believe that aliens exist. I wrote a paper about how adaptive life on earth is, and it turns out that life on earth adapt very well in extreme conditions. Which makes me think that there is no way that life as we know it is the only life in the universe.
Im 2 hi for this lol
not really... u need to support unlikely and likely.. otherwise its I DONT KNOW...
butt first we have to get past the part of if life on earth is just a utter anomaly rather then highly likely given the size of the universe..
we literally know what chemicals and reactions are need for life.. yet we still cant START A NEW LIFE.. so this begs to question .. if there are billions of earth like planets with all the same and similar chemicals reactions as such happening.. there is no evidence that whatever CAUSED life happened there too...
what we're doing is 100% lookin only at life on earth with NOTHING to compare it too then projecting EARTH LIFE onto other planets in the universe..
what if earth life hypothetically is the WORST and least likely method for life ..? a freak accident that was so unlikely that it takes billions of mulitiverse just to even have a chance and we just happened to happened..?
how do we know it doesnt take billions of multiverse to act on each other to create a single universe capbible of life?
to me.. "the universe is so BIG there has to be life" is like saying "the universe is so BIG therefore god"
its like "i dont know so therefore god" = "our math breaks down therefore infinity"
yes "infinite" is what we say when MATH no longer works... and from my understanding thats HUMAN ERROR... we jst dont have the know how to solves certain issues yet so we say INFINITE..

The other thing to consider is that there may be concepts we haven't even come up with to do with issues of being an even more advanced species, limits we can't even conceptualise at this stage of our development.
Thankfully there may also be solutions we cannot consider at this stage as well and therin lies the optimism. We got this far, lets see how far we can get together.
I've actually watched another video that said our position in space is actually a pretty big void, which could be the reason we don't see colonies of other species, and why they don't see us.
Yes. We are in the suburbs of the Milky Way.
Do you know which video that is
The thing is, we are making a lot of assumptions about aliens and their development. And currently the only example of a technological species we have is ourselves. A species on another planet may develop technology along a different path than we humans have. Depending on their own evolution, environmental factors, or perhaps even their position in the galaxy.
An interesting example of an alien race is from the Andy Weir novel, Project Hail Mary, (Minor spoiler warning) there is an alien species that evolved on a world closer to their sun than ours. They have a higher gravity field, and a much denser atmosphere. So the surface of their world was pitch black and very hot. Their species did not evolve eyes, but used sound and a form of echo location. Their language was more like musical tones. Their bodies evolved on a world with a higher atmospheric pressure. So because of their planets condition, they had no concept of radiation. They had not even developed computers or radio. There had been no need to.
The long and short of it is, its not that Aliens are not out there to hear our messages. We may just be sending the wrong messages. They may have no ability to hear our radio signals at all. They are not us, so assuming a similar developmental path is asinine at best.
Wow, very profound. Our environment dictates our evolution which dictates the way we interpret and experience reality via our senses which in turn dictates our technological path
I'm learning more from 10 min yt vids than from my 10 years of public school.
Yes, public school
Maybe the question isnt where is the all the life...maybe the question is when?
We could be the first, or we could be millions of years late. They could be so many light years away that we wont even see them for several thousand or million years
Or maybe we just aren’t interesting enough for them to bother? There are a hundred ant hills in my yard, and I’ve never done anything but pass them by.
I get the feeling we are late not early. our solar system formed 7 billion years after the first stars came into existence who knows what has already happened. for all we know there have already been a galaxy spanning war 6 billion years ago where all intelligent races were exterminated.
@@ocirontariocryptidinvestig8010 actually it took many supernovae in order to produce higher elements in the Universe so no, there could be no other life 6 billion years ago because it most likely would not be able to form from hydrogen.
But if the universe is older and much larger than the observable universe then it might be true.
@@ToDie4r I would have assumed that elements would degrade in number as stars died and were reformed into new solar systems. I don't really believe we have the ability to know what was contained within stars across this galaxy 5-10 billion years ago.
@@ocirontariocryptidinvestig8010 that is a fact, with respect to standard model and Big Bang. It's necessary for a star to be enormously big in order to make enough pressure and heat at it's core to make higher elements. Especially gold for which i think it's produced only in supernova explosions, as every higher element. That's just the way physics is my friend :) Follow Dr. Physics on youtube he has wonderful content.
Best regards.
I think life as we know it is probably rare when compared to how many planets and star systems there are. If we’re looking for aliens “like us” we will probably be looking for a very long time. And then you have to think about how far apart we are, separated by not just space but time as well. We would have to literally stumble across aliens in a moment of sheer blind luck. The universe is an absolutely huge place.
Like being lost at the Atlanta Airport.
Scouring Terminal 1 for your lost luggage, when all the time it is rotating on a conveyor in Terminal 3.
How about this... We Are Not Alone, We've Never Been Alone. The rest of the universe has had a multi-million year head start on Earth. Earth and humanity is EXTREMELY late to the game - ok. Aliens and more correctly put, Advanced Beings, have been visiting this Earth for many millennia. and aiding humanity on multiple levels throughout our civilization. The saying goes "If you want to believe, the truth is out there. If you don't believe, no amount of actual evidence will ever suffice." HTH
Here's how I think of it: Imagine if we take Earth, flatten it out and stretch it proportionately to the size of the observable universe. Now consider how far apart you would be from the closest person you are nearest to now.
What….?
We think that our world is huge, but we seem to forget that the Earth is just a tiny speck in comparison to this galaxy, and this galaxy is just a speck in the universe. Even if there were another civilization we could communicate with, I couldn't even imagine how far they could be.
@@tommiezturner6554 I'm saying even if there are as many living organisms in the universe as there are people on Earth, the likelihood that any one of them would be remotely close enough to us to find, much less communicate with, is so close to zero, it might as well be zero.
Great expression
@@DannyLou03 by time their signals reach us they could have been dead for millions of years or vice versa
One of the more likely answers is that we are one of the early first wave of advance species thus why we have yet to meet any other life as they are at a similar stage as us. The second is that advanced life likely does not wish to make it self known to us and let us advance naturally to a point. Think of it is like the prime directive from star trek.
@@yourdaddy.956 I know right! Just like the lizard overlords living in the hollow earth.

"Intelligence is just the right thing to have to render yourself extinct." Wow, that's a depressing notion, but seems likely true. It's probably not intelligence itself, but it's the transition between low intelligence to high intelligence. A civilization has to cross that precarious void of learning how to harness vast amounts of energy, AI, nanotechnology, etc. without destroying itself or overconsuming resources. It's a pretty good possible answer to the Fermi Paradox: it's just extremely hard to stay alive for very long in this universe.
8:31 "Inteligence is just the right thing to have to render yourself extinct." ..... I have never thought of it like this and it amazes me how true it actually is.
I'd just like to say the visuals in your video are immensely satisfying to the eye. I'm curious, do you have your own graphics department, do you outsource the visuals, do you use royalty-free graphics?
Given how we haven't really been able to get very detailed information outside of our own solar system, it's probably just a matter of we're too primitive to find intelligent life. And given how we're fast-tracking our own extinction, it looks like intelligence didn't really do too much for us.
Given how knowledge is a self-propagating and exponential process, there is unfortunately no particular reason to believe that any other intelligent species early in its evolution would find themselves in a significantly different position than we face now. Any one of them would almost certainly face a point where they learned to split and fuse atoms, and develop industries and technologies that they understood poorly and used unwisely. Right now technology itself looks like the most dangerous Great Filter to any intelligent species.
We have had some rough patches. We will have more. However, we are still here. Still learning. Still expanding. Our first radio signals, by now, and crossed 10s of thousands of planets and it is still going. A bit of faith and even more patience. We'll get there.
If the phrase about "if you tell me you dont think you can do something or you tell me you cant - they are both right. (it is something along those lines) If we focus on self destruction, we might have to prove ourselves right. Better to not go that route.

I sent this to SETI:
I realize that folks in the science community don't like suggestions but I feel like this one is super pertinent to SETI's plight. So please hear me out, it's short.
Sure communication through space is seemingly unobstructed when you think about objects near/within our solar system, but I'd argue the effects from orbiting bodies, scintillation, and the inverse square law will not allow signal acquisition from entities light years away. And thus Fermi's Paradox is flawed because it assumes specifically the acquisition of signals from distant orbiting bodies. Any where past light days, the signal is spread out through the cosmos instead of being tightly packed which all but ensures the data can never be decompiled/processed.
At first I thought the issue for the broadcasting entity could be remedied by utilizing a spacecraft and performing a Homan transfer to align your velocity vector with the target planet. But I fear that alone won't be enough to mitigate the sun's gravitational effects (on the signal), even with the Delta-V.
Instead I suggest that if you want to transmit a signal to a solar system light years away you need to have the spacecraft Homan transfer to the velocity vector of our sun targeted on a system in that direction. Then radiate our loudest/powerful signal. In addition I believe scintillation effects are too compounded if the transmitting entity is targeting a solar system that is edge on to us. So I believe you must target solar systems that are aligned with our celestial plane. Further, I believe that if you want to listen, you'd point your antennas to star systems in the neg in-track of the sun. And once again those systems should be aligned with our orbital plane.
Talking to Voyager is not easy and that signal and our ground systems that acquire it are dealing with very low signal strengths and super high signal to noise ratios. And that's just 5 ish hours of light speed away. Instead of asking why isn't anyone broadcasting, we should ask why can't we hear them? I think this is why.
I believe I've laid out a good angle for a revitalized concept of operations for you all. I hope you all pass this along to the proper folks. I believe it's imperative. Ty ty for all y'all's hard work! The work you all do is extremely important to humanity.

@@stevencoardvenice good one
3.5billion years is still about 1/4 of our universe age. It feels like our universe is actually pretty young because that must include the time it takes for planets to cool down and be ready to have life.. I think it is very legitimate to think that we are some of the first apparition of intelligent life in our universe.
If aliens are well above us theyd know better than to interact with our species while we're young and undeveloped, they're also be smart to jam any sort of communication efforts coming from us to insure we don't reach out before we are ready, they could be literally watching over us like babysitters

We have examined our own physical and dna heritage and have managed to draw a pretty detailed lineage back over the course of billions of years at this point, so, no - right now we can be pretty confident that we grew up here.
@@Vastin you are thinking of humans as we are in our current form. The seeding of Earth with the building blocks of life is what would make us alien. I think the building blocks of life are common. The environment needed to support life may not be but we know for a fact that it is possible because we are here. I don't think life in general is all that rare. Intelligent life probably has occurred, exists elsewhere now, and certainly will in the infinite future.
@@marcus1282 It is certainly possible that life on Earth was initially seeded from a non-terrestrial source, or influenced by one if it were early enough to do so before we could really detect those change in the fossil record - but if that's the case, that 'extra-terrestrial' life would have been here for literally billions of years - not really even legitimate to call it 'alien' at that point. The distinction would be essentially meaningless, it would still just be 'life as we know it' in any meaningful sense of the term.
@@Vastin I don't really see it that way. It doesn't matter if it were yesterday or 4 billion years ago. If true, it would be important to understand. People want to know what circumstances started life here as it may help us better understand where it may be elsewhere. Of course, if true it doesn't mean that our circumstances have to be present in the exact same way elsewhere for life to occur. There may be infinite possibilities and I suppose that is what makes thinking about all of this so much fun!
No. It shows you don't understand.. There is a reason that math is a universal language.
We use certain symbols to communicate. The phenomenon those symbols represent are fact. For instance, if you use the law of identity, something is what it is and never what it is not. A rock is a rock and never not a rock. Even if you don't use the label rock.
Physics is the same. Doesn't matter what we use, the phenomenon is apart of reality. An advanced species would understand math
1+1=2. Period.
If aliens would have come to earth during ice-age, "A ball of ice with no life in it" would've been their logical conclusion.

Rather than looking for a job, This is my very important subject for me as a 3D designer “from symbolic to complex “ and I think I go the structure that’s connecting every mesh in models as “tree leaf logo”!

Something I don’t understand is if it’s true that life got going relatively quickly and easily in the Earths life then shouldn’t we expect to see it happening more than once, with several separate trees of life with their own independent genetic lineage rather than the single one we have?
Maybe very, very early on there might have been several false starts, or attempts at different types of self replicating chemical processes that might have competed with each other for a time - but its likely during the very primitive era that only a few approaches were remotely viable, and that number probably got whittled down to one - which would have been the ultimate pre-cellular ancestor of what become the RNA/DNA strands at the core of all living things on Earth today.
Once those early protein strands managed to become decently established and began to develop and diversify, its unlikely that any other new process would be able to competitively establish itself in the tide-pools and chemical morass of the early environment on Earth, locking the biosphere into a single general course for a long time until these little guys became robust enough to develop into more and more specialized environments, becoming the general branches of life that we recognize today.
We are not alone I believe
"When are all the aliens" might be a better question, perhaps.
I’ll do you one better, “Why are all the aliens?” 👽
Where all the aliens? they are living on their planets i guess?
We might be the last intelligence that we've been looking for, that's why its taking like forever for us to find new life somewhere in the cosmic. And in my opinion the signals that we received, just arrive in our direction after a thousand of years that passed.
Very interesting, I would say that that due to the sheer size of space (endless) that we are simply hidden within the universe from other forms of intelligent life. (Toothpick in a haystack)
More like a grain of salt in the sahara.
But intelligent life is rare. Neil said it himself. Millions of species on earth in the last 4 billion years have developed eyes, and mouths, and ears, and hair, etc.. But in 4 billion years, on a planet thats abundant with life, intelligence has happened only once.Thats proof beyond all doubt that intelligent life is extremely rare and possibly even unique to us.
@@joshualee7709 just my humble opinion but maybe intelligence has happened, but it has never passed further. Perhaps this is the edge. Any further and its only void.

Just my morbid prediction but once the james webb space telescope launched, if it cannot detect something awe-inspiring like an actual civilization in its images then human intelligence will have little to look forward to.

Maybe this is a strange thing to think about but I love the idea that maybe one day we can make contact with an alien civilization and learn their language and be able to communicate with them and make some alien friends. And maybe they can in turn learn some of our Human languages. Maybe it's because already as it is, I have a huge fascination with learning other languages than my own, and the idea of communication and talking to people in general. I feel like it would be so cool to learn another life form's language. Who knows maybe there's an alien civilization out there that's like us humans here on Earth, where they have different languages and appearances and cultures depending on the region of their planet they were raised. I think it would also be cool to use slang in an alien language. It already can be difficult learning a new language, let alone learning the proper way of speaking it vs the more common slang used by native speakers especially the youth. It does make me a bit sad to know other life forms may be avoiding us if they are out there and know of us, but I don't blame them either. All though we have so many amazing people on our planet, the way our species tends to behave, we can pose a potential threat, and on the chance they've raised beyond that, they probably don't want to start some kind of unnecessary war. So maybe it's for the best we never make contact with other life forms. Our species tends to take anything foreign or unexplainable as a threat, and it would be very likely for us to attack, causing mass destruction and a shit ton of suffering, on our side and their side. I wish this wasn't the case, because imagine all the nice and wonderful people you could meet. You could hear stories from them about what their home planet is like and where they grew up. Maybe learn about the types of plants they have, animals, the weather. Maybe their days and nights are far different from hours. Like for example, maybe a day could be like 48 hours for them on their planet or maybe even a bit longer. I wonder what their homes would look like and if they have forms of education and places like schools to serve the education. Who knows maybe they'll be nothing like us in anyway. And maybe that's what truly keeps them far, far away from us. Because we're so different and unpredictable that they don't even want to risk trusting us. But again, I don't blame them. I would be afraid at first if aliens came into contact with us too, even though it is very cool in retrospect.
Imagine wondering why you haven't found life in the universe when the farthest you've been into space is only as far as your own moon.

You know we have probes that have recently left our solar system right? Granted it’s a big empty space so chancing upon something would be a miracle
And don't forget: We have sampled TWO planets for life and have found evidence for life on BOTH of them (Earth and Mars)
SO far the chance of life on a planet is 100% according to our sampling.
AND we have discovered THOUSANDS of extra-solar planets.
It would be illogical to assume no life on them.
@@AFreeThinkingDawg09 I was thinking more in the present and accounted for sense. Yeah, we've sent probes further. But really, we've only done the equivalent of leave the house and walk to the sidewide and peak down the street.
@@littlebabyhoho6750we haven’t even made it out of the house yet much less the sidewalk, AND all the lights are off so we’re feeling our way around the dark for the light switch still. Intelligent life is 100% without a doubt, there. I just hope it’s a good experience when we do stumble upon it bc we’ll either be the lion or the mouse and my bet is that we’re the mouse. A very aggressive mouse lol
Or maybe they're all miniaturized cybernetic life forms who've learned to live so efficiently and have so much going on in their virtual realm that they've lost all motivation to care about the physical realm.
That almost sounds like some of my friends.
Cybernetic. They live through their Phone and computer.
Live efficient. They have an income without doing almost nothing and they get food etc.
They live in a virtual realm. They live 85% in their games, and 15% in the real world.🤣
thats also one of the Fermi-Parodox solutions
Too busy on social media ...
@@ShutUpWesley Think where we'll be in 250 years if we can maintain our society and keep progressing technologically.
It certainly seems to be one of the more realistic solutions to the Fermi Paradox - and the lightspeed barrier.
Our current physics strongly hint that it's much easier and more efficient to build *inwards* than *outwards* in terms of increasing the scope and scale of our civilization.
If the closest extraterestrial civilisation able to radio transmissions is just 300 parsecs away and is transmitting for 2 centuries we need more then a century from NOW till we pick something up...
300 parsecs = 978LY. Assuming a transmission lifetime of 200 years, that would correlate to a 400LY radius with the transmission energy decreasing by a factor of 4 as the distance is doubled according to the inverse square law. So you would need at least another 275 years to listen.
Sometimes, you have to go beyond knowing everything and know nothing to find what you are looking for. There are riddles in your own backyard that are avoided (publicly) that will lead you to your answers. Somethings are stranger than fiction and the ones who continue with the strange will find life beyond what you "know". Be brave.
I’m open to all possibilities. There’s a very interesting book “Man Being Volume 1” that proposes a new origin story. Found it extremely compelling.
👽👍👍👍
Well... Are you going to tell us about it?
So, what is this origin story?
@@_Breakdown That humans are originally freeform Light Beings that are stuck in a gateway. Earth is a petrified gateway. We are time travelers that have forgotten our way home after thousands of years trapped here. They even suggest that what we are calling “extraterrestrials” are simply humans that have “died” and take on another form to travel to our dimensional space. Something to that effect. The books go into much greater detail than this…but that’s the best I can do to condense 4 volumes. There are reasons given as to why we are trapped and who is responsible and how we can leave this capture or matrix as some like to call it.
@@benparsons4979 That we are Light Beings or Travelers stuck on Earth and caught in a reincarnation loop. See my response above.
We will escape the extinction 😢😢😢hope .....

We need to dig
Aliens are too busy with their day to day lives but they have left a game called "The -Sims- Humans" for their kids to keep them occupied 😉😉😉
Well said!!! Where did Apeman come from? Darwin was dead on about species crawling out of the Ocean, but what about us? Were we dropped here?
@@tweetybird59 no, we also evolved from those creatures that crawled out of the ocean.
Professor Brian Cox just explains things so much more clearly and calmly. Chill Neil chill....
Intelligent life sure seems to interact with our military.
Just because you've seen something I'm a documentary doesn't mean it's real
Fax I remember growing up and I had a freind who I considered a brother bc our dads were always hanging out and his grandma was in the army and she would go on and on about how aliens do exist and area 51 is real and a bunch of other shit to this day it makes me think Hard

@@-_James_- why?
To young to explore the world to old to explore the stars this is a reality I’ve been struggling with for sometime I hope my children or grandchildren will know the answer
You know what surprises me is the fact that we have this life long question about how we are alone in the universe or not. I think the fact that we even believe that we are alone in the universe is the most arrogant statement an intelligent species could possible say because the universe is vast and even if a intelligent species had the ability to travel through space faster than the speed of light which is nessary to get anywhere in the universe in a reasonable time period. what makes you think that they would seek us out we have only been technologically advanced for the last 100 to 200 years on the human time scale and even then we have barely scratched the surface of interstellar technology so do I think life is out there yes absolutely but do I think it's likely we will ever find other intelligent life not so much.
It's almost like its anti-arrogance. When people ask 'Where are all the aliens? ', I just think... look at the popular culture, it's corny but think about it... crop circles, stealing cows, kidnapping people, experiments... I ask "Why haven't we been doing that?" Going to other planets, stealing THEIR cows, kidnapping THEIR people... drawing crop circles on THEIR land... It's because we don't have the technology. If WE don't, what makes us think that THEY do? They're likely trapped on their worlds just like we are on ours. It's super-arrogant to think we're the pinnacle of life in the cosmos, but it's anti-arrogant to think if there IS other life, they are all more superior than us.
@@gettps very true a fact that most people don't know is that traveling at light speed is not only not possible currently but its not even efficient enough to be Plausible for space travel so unless we find how to use worm holes which unlikely that they even exist we will permanently be stuck and limited to our own solar system.
Are we alone in the universe? Yes. So there’s no other intelligent civilizations in the universe? No there is but they are alone too.
The Fermi Paradox is so overexplained. We know what it is. We know what the problem is. The next time NDT or any other famous science announcer mentions the Fermi paradox is when it's solved.
It's a popcult thing (network earning). Same as the Drake equ. If they are there, they are there.
If they are here, well... Bollocks!!!
@@gorankeem8126 anyone who says "if the exist , why haven't the contacted us?" has absolutely no idea about the size of the universe and the distances involved.
@@Gantali9305 Sure, and by the same token even if there are thousands of intelligent species in the Milky Way today, it's unlikely we'll ever be able to do more than feebly blink at each other across impassible light years.
@Science Revolution ....Are you ok?
@Meta Man Drugs are a hell of a drug.
To get technological intelligence your animal must have 3 characteristics:
1) A need for fire and the ability to make and control it, for without fire you cannot manipulate materials.
2) Be a social creature, not solitary, since no individual can develop technology on their own.
3) A sufficiently long life span to develop skills and pass them on
Take the octopus. A good candidate for intelligence. It demonstrates complex thinking and has the dexterity to make tools. However, they live in water so will never need nor make fire. They are solitary, so do not share and pass on knowledge. They live for only a few years so only have time to reproduce and die, no time to tinker.
I suspect that getting life that has those three characteristics, and then develops them to high levels without destroying their selves, is extremely rare in the universe.
It’s a possibility that aliens don’t have the technology for interstellar travel because it’s simply impossible. Imagine the power source needed to move solid matter at relativistic speeds. What happens if you hit a speck of space dust traveling at 99% of light speed? Maybe it’s just not possible.
We observe MANY things in the universe that are "Impossible" according to current physics.
FTL will be possible. Thinking it is NOT possible while we are literally in the infancy of "Technology" is being arrogant.
@@stuartgray5877 we would need *at least* one Dyson sphere to even search our galaxy. So several to explore galaxies. It would require the power of a Dyson sphere to even create one. So interstellar travel is essentially impossible. Check out kurzegsagt (sp?lul) they've got lots of cool space vids
@@sarah69420 I suspect that all we need is compact Fusion power and we will be able to travel FTL in the next 100 years.
Just use force field
@@sarah69420 ftl, warp speed, bending space. you do not need a vacuum cleaner to do that.
It is interesting to note that there is no record or evidence of more than one occurrence of the origin of life on earth. If it is so probable, why is this? Did life only arise once under these supposedly ideal conditions?
Still plenty of spots in our own solar system to look.
The clouds of Venus, the oceans of Europa, the ice caps of Mars.
don't forget Titan!
Trying to find alien life within just our galaxy would be like trying to find a single ant on their entire planet. It’s nearly impossible.
The planets in our solar system were formed by the same clusters of space debris so given the right habitat conditions the chance of finding evidence of life somewhere in the milky way is probably very likely. Also early mars was very similar to earth. If life was able to develop in the first 200 million habital years on Earth then there is a good chance the same thing happened on mars and/or any other habital place in the milky way.
@@rileyxbell our likelihood of finding any life is slim to none. The universe is just far too vast. Our electromagnetic and radio signal frequencies have reached about 200-240 light years in all directions after transmitting for 126 years. If we continued transmitting for the next 10,000 years we would only reach 1/5 of 1/2 the Milky Way. Then we would have to wait for them to transmit back. It’s incredibly likely we will never find life outside of our own planet
@@rileyxbell trying to find living, intelligent life in just our galaxy alone would be like trying to find one special ant on the all of earth. Nearly impossible and that’s just our galaxy.
Assuming we are not alone, we have two insurmountable obstacles to overcome before we can make contact: 1) the sheer, unimaginable distance and 2) time, because we are but a blip in history. Give or take a million years makes a big difference as to whether we observe life on another planet, even if it's next door - we could either be early or late in our observations and the chances of us coexisting with alien life that we can actually reach is really zero (this is often confused with the concept that there is/was/will be a high probably of alien life out there, which I'm not disputing). We may one day have to accept that we are, for practical purposes at least, alone.
