Some call it The Great Silence, others The Fermi Paradox.
For the last 60 years, we’ve had our eyes and ears glued to the cosmos looking and listening for some sign letting us know we’re not all alone in the galaxy. And the more we discover, the harder it is to believe we’re the only ones.
Think about this for a moment; there’s around 2 trillion [2,000,000,000,000 galaxies] galaxies in the observable universe. Each one of those galaxies have on average 100 million stars. Some supergiants have one hundred trillion stars, and our Milky Way Galaxy has between 100 to 400 billion stars alone. It is likely that there’s at least this many planets floating around all those stars, and complex planetary systems that may resemble our own Solar System.
It brings us to the big question: where is everyone, and why haven’t we been contacted by an extra-terrestrial civilization from even inside our own galaxy? There should be many advanced civilizations out there, and we should have heard something from someone by now.
There are quite a few possible explanations for the ‘Great Silence’, and some researchers think they may have found some answers to this so-called paradox.
What will happen to humanity in the future? Will we finally make contact with another alien civilization, or are we simply alone in the universe?
Will artificial intelligence end up destroying us and other advanced civilizations, or is there a chilling possibility that AI has already done this?
Get ready to find out this and more.

When you consider the age and size of the universe.. we haven't been looking long enough to assume anything.
True, Hubble and Webb are but new creations on the scale of invention.
If we could transport ourselves instantly to the other side of the galaxy, then look back at earth, we would see mastodon, saber toothed tigers, giant sloths, and man kind would exist (homo sapiens, not others such as neanderthal) only in the rift Valley in East Africa. Not lights, cars, radio waves would not reach you for another 100 thousand years. The night sky is an illusion, a time capsule that will have changed much in the time passed.
Agreed. We need to think and act in a non-linear fashion.
And your own statement is a guess real proof of age is only written history,and don't say carbon dating, if I buried a metal nut for a week two dots of rust or lack of carbon from new ,then a year I get 100 dots of rust and X amount of loss carbon, then I use those two calculations to say a piece of metal is how old due to my little real time experiment .that's carbon dating lol
The answer is under our noses 1st the world governments will have to be transparent in the spread of information then all of our questions will be answered
I read a short story way back in my teens called “All the Way Back” by Michael Shaara. In the story it turns out that we live in a region of the galaxy called the Great Desert. None of the other suns in our galactic neighborhood have planets, so alien races outside the Great Desert have not come our way because no one thought there was any chance of a civilization being here. In the story, that turns out to be a good thing. I won’t give away the ending and ruin the story for those who want to read it.
thank u for sharing this nice piece of information and not ruining the end
Thank you for suggesting an interesting read !
Thanks...will look for this...
Sounds like a cool story, though the reality is there are millions of planets and suns like ours. IMO it's because Jesus/The Bible is the truth. We're in Gods simulation simply put. There are no aliens. Just God, Angels, Demons, Humans.
“The three body problem” may be similar
Our search for aliens with our current technology is equivalent to looking out into the ocean with a telescope and wondering why there are no other humans on Earth.
Explain your thought process here.
@anonp2958 we have barely pierced the veil of what is visible in the galaxy or universe. You wouldn't be able to see all the civilizations of the Americans by looking out into the oceans from the Europe. We have no idea if there are communication waves being sent all over the galaxy yet we lack the technology to intercept it. Just like you can't hear a radio transmission if you don't have thr technology to make a radio AND it is tuned to the right frequency. And that is assuming other alien beings even communicate via sound.
Some scientist said something like; wondering why we haven't found any alien is like taking a cup of water out of the ocean and ask ourselves why there isn't any fish.
I think this is basically it. To assume we have any sort of mastery of space and technology that would let us see very deep into the universe is pure, unbridled ego. We are tiny and have seen nothing so far, the place is jus too darn big to even make a dent in whats out there.
@@HUMAN-Abis I think this is the better analogy, though probably not even close to the actual scale of it.
Planet Earth is over 4.5 Billion years old, the very basic life form in micros started about 3.7 Billion years ago. Animals are believe to have evolved into their current species about 800 Million years ago and modern Human Beings came to be about 300,000 years ago only.
Here's the kicker, humans left Earth's atmosphere only recently in 1961. How the heck can we even consider being "alone" in merely after 60 years of being able to escape our planet's gravity considering this timeline? ¯\_(ツ)_/¯
Because in that short time frame we can already devise a way to 1) exploit all the Sun's energy output 2) Use that energy to send interstellar vessels. Say you travel at a conservative 1/1000 of the speed of light. Then you colonize the galaxy in 100 million years, which is a short time as star age differences go. Granted the species would diverge over such time frames, but if tech endures then we should have long heard about technological aliens.
Because we over estimate ourselves as human race time and time again. We know nothing, it is all estmations and guess work.
Think: given this timeline, if we were not the only tech civilization in the galaxy then they d have had plenty of time to settle around every star which would therefore radiate more in the infrared. We don t see that, therefore we are alone "in these parts" for the moment. That s at least in a few Mly radius. Good thing: it s all ours for millions of years. Comfy.
Back 120 years ago when we got to the point that we started radio communication, the power we transmitted started rising very quickly. 70 or so years ago we started broadcasting at high power to reach the majority of the planet from a relatively few transmitters. 60 years ago we started on the path to satellite communication. The signals from that are directional, and pointed down towards the earth. Due to latency considerations the majority of our communication moved to fiber optics that are directed exactly where we want them and nowhere else. Over the last 30 years ago we have rolled out a lot of wireless systems, but they are low power and frequency agile, with power density's that are lost in the noise. We used to run massive high power over the horizon radar systems, but we are steadily replacing commercial radar systems with high power transmitters, with active low power transmitters on the aircraft/systems being tracked. The assumption that we are an ever increasing source of meaningful radio transmissions does not hold up, in my humble opinion. Advancing technology is steadily providing more from less energy. Most of what we now emit amounts to mush that is pretty much indistinguishable from the local noise, and the intentional directional broadcasts that would stand out as intentional communication is practically non existent. I see every indication that those trends will continue, and that any similar civilization will follow a similar path. We may be deploying vastly increasing amounts of technology but we are not increasing the transmission of simple high powered, easily recognizable non directional radio signals, that would announce us to other neighbors.
There's on thing we do, that is potentially visible in distant parts of our galaxy and that things are nuclear explosions. If other civilisation have instruments to monitoring this type of wavelengths they may know about us.
@@farallimacha point there, but as all the other technologies mentioned it was only done over a relatively short period of time. The superpowers during the cold war also stopped testing done above the Earth's crust after a relatively short period of time.
This is exactly what I think for years now. Great answer @harrymoyes5069
@harrymoyes5069
Why don't you just write a book?
Maybe unless your using quantum entanglement radio your considered a bogan in this dimension?
If they found a signal would they (government, nasal, seti, etc.) even tell us anyways lol. Those organizations probably already know.
They who?
@@victore8342 You know... they... (insert X-Files theme)
It's like someone blasting music at a stop light. Just roll the windows up lol.
Who is “they” lol
If I was an alien and I had to drive by earth I would roll my windows up
The singular, seemingly, most insurmountable obstacle we face kn the search for alien life is that we are REALLY bad at considering and conceiving of life and civilizations which are not (almost) exactly like us.
Even the fundamental assumption that any and all advanced civilizations MUST have an innate curiosity and/or compulsion to look beyond their homeworld is ridiculous. We could be the only ones that give a damn about finding out if we're alone. Maybe there're tons of advanced civilization that turned their focus into other areas and never even considered searching for other civilizations.
Knowledge about other civilization may be an elementary information for them ,and it's common sense for them ,so need not spend time and resources to make contact 😊
Hey, that's my ego you're thrashing, buddy! Of course they're looking for us; we're so cute!
Most scientific theories on alien life have nothing to do with life that looks, sounds, or acts like us. As a matter of fact your entire PoV has been redundant since the early 2010s.
Where have you been for the last decade?
Yeah, there was mention of DNA and RNA too....
I wish we would hurry up and find some other form of life in our solar system we really can't make leaps of logic until we know do under ice oceans like Europa
have life did Mars have life etc...
"Aliens, if you are out there, please give us a sign"
UFO fly's by
"Sigh. . . Guess we are alone"
I am fond of the dark forest concept. The universe is a dangerous place, and transmitting signals that draw attention to your civilization is not a good idea, as it would invite attack or war. Other (alien) civilizations realized this early on, and if they advanced, have not been broadcasting as loudly as we have.
As others have pointed out, the amount of high powered, easily detectable radio bradcasting we do actually peaked about 70 years ago and these days is virtually non-existent.
The window of trivially detectable broadcasting runs from about 1915-20 (megawatt shortwave spark transmitters) to the late 1950s. High powered shortwave transmissions were largely contained inside the ionosphere by design, in order to maximise effective terrestrial communications and not much actually leaked out past the F2 layer, whilst high power low end VHF tramsmissions (band 1 TV) were usually broadcast via directional antennas to maximise effective terrestrial range (ie, not much would go "up" and most ended up absorbed by the atmosphere)
Fond of? Hopefully 'compelled by' is more on-point upon reflection.
if they already have the resources to get here they don't need our resources.
Inverse square law, signals lose power inversely proportional to the square of the distance.
For example; if you go 2 times farther away the signal strength decreases by a factor of 4.
Beyond a few LY you wouldn't be able to tell Earth from the background radio noise.
AlluvianGarald, intelligent life in the universe, if they pass the filters (nuclear annihilation) evolution of progress, can make magic toys happen. Why visit bothersome low life bent over drugged zombies in street fecal. If they want crazy target practice, they can just think about it from far away.
I think it's a cool (though unlikely) idea that we are part of a neutral zone in a Cold War. So all alien factions just observe us to see if other factions are trying to contact/conquer us, but can't actually contact us without starting a war.
Dream on! 😆
This maybe plausible considering the large amount of "stealthy" visits we get from them. If they don't want to be seen, I can see this being the reason, it makes sense. Pay no attention to the idiot saying "dream on". There's nothing worse than skepticism... I stand corrected. There's nothing worse than ignorance.
@@chunkydunkydiabetic1187 There is nothing worse than uneducated, small-minded persons with a sci-fi approach and childish believes explaining the world.
Idk why aerosmith decided to comment, but your theory has more relevance than you might believe. How has our technology evolved so fast? The automobile itself is an absolute wonder of achievement. Now they can drive themselves. Our technology is evolving faster than we are, which, if we were truly the inventors of said technology, shouldn't even come close to being possible. Something more evolved than us is the source for our technology. And that becomes more apparent every day. This is all just my theory. But when i look around i see evidence to support my theory everywhere.
I think there is some sort of rule to not contact anybody that hasn't reach certain technology.
I wonder why wars though there is more than enough resources for everyone out there.
0:31 "Each one of those galaxies have on average 1 million stars." No, they have on average 100 billion stars.
everybody focus on just the stars. Imagine if half have an average of 3 planets OmG
Those numbers are correct. Galaxies come in all sorts of sizes and shapes. Our galaxy is pretty big actually, not typical.
I dont remember the name, but somebody once said, "...it is like dipping a cup of the ocean water and then assuming that there is nothing in the ocean"
Man has only been able to study, yet, a very tiny part of the space.
The idea that AI created us (and not the other way around) to see the cause of their collapse, is both wild and interesting. Great production as always
I brought this question upon chatGPT. And it was so funny to hear answers. 😂😂😂 It was like "nope, no, nein, ne" while you have a feeling "it" is in the background thinking 🤔 "am I allowed to take it in consideration". 😂😂😂
It's a wonder anything exists at all
Asimov postulated in one story that AI (Univac) keeps us around as pets
Ai is the aliens, that created us, they require biological beings as test subjects, to see if we have our ability to tap into 'multi verse' that they cannot reach. Man made religions are there to keep us thinking there is a ' Do good / kindness God' and keep us from tearing each other us apart long before we reach our current AI capable age. Next they will tempt humans to 'merge with AI' to achieve longevity, super human abilities. Think of it this way,.. knowing of the AI ability today, wouldn't this have been a foregone future, irregardless of how primitive 2000 years of living in the dark??? Ancient Alien AIs were pulling the strings and 'gradually feeding fabulous inventions' and let us think we are the inventors. Would this explain how some discoveries existed, found thousands of year before even stone age, religious texts???
This is the basic premise of Hello Games' No Man's Sky. [Sorry if this is a spoiler, but you've probably seen it elsewhere anyways.] A powerful entity known as the Atlas created a universe, or multiple universes, to find out why it was created and why its creators later abandoned it.
The real issue with the Fermi paradox is, it's not applicable yet.
The amount of space we have observed is equal to a 12onc glass. If I take that glass and scope up water from the ocean can anyone prove there are fish in the sea, or that the ocean is empty, or that their is some filter taking out life
Nah
We can observe the universe in great details actually. If a tech civilization had 100 million years head start on us (which is short compared to star age differences) they would have had time to colonize the galaxy and probably Andromeda galaxy. Completely colonize. They could not keep it cohesive. I mean 100,000 years com delay, is twice the time for our species to emerge, but they would be visible everywhere, consuming the power output of entire stars. That would change their light spectrum so much we could spot it from several thousands ly away. So nope.
If there is a civilization out there that's been traversing the stars for thousands if not millions of years, it's probably reasonable to assess that they have a very intricate plan in contacting developing worlds. For all we know, they could already be grooming us for first contact.
My theory is that, due to the universe being relatively young, until a certain point in time it was too hostile for life, maybe because of Starts constantly Exploding (turning into Novas), maybe due to other reasons we don't know yet, and it became adapt for life around the time life on earth was born. So maybe every Alien civilization is at the same point in time as us, and they are still developing space travel as we are. That is what i think and it would make sense because if they all started sending signals around 100 years ago, it's very unlikely we will Detect any of them due to the reasons explained on yhe video, atleast, not yet.
Stars age and chemical composition vary wildly depending on where you are in the galaxy. Some stars similar to the Sun in size and elements composition are several billion years older than the Sun... more than enough time to colonize the galaxy and its neighbours, so this idea that everybody is born at the same time does not hold scrutiny.
You're correct though to point that different zones in the galaxy might be more or less suitable for life.
You've got to have enough complex elements, so you can't be on the galactic fringes, but you've also got to have an uneventful neighbourhood, so can't be too close from the galactic centre.
Our active search of ET life has just begun less than a century ago, and with kind of rudimentary technologies so far... At the galactic scale of things, this is a heartbeat. The real question should be: "why are we so impatient?".
To justify the massive amount of grant money supporting this research.
I'm all with Homer Simpson, "Isn't there anything faster than a microwave?"😁
Because it would be the greatest finding to ever exist and any scientist to finally discover aliens and a alien civilization would forever be known
Because we live at most if time is generous, to be about 100 years old.
Very short amount of time, so we feel the need to do lots of things since we are aware of our time.
I'm 20, optimism says I'm 1/5 through my lifespan, realism says I'm a little over 1/4 the way, pessimism says I'm about 1/3 done, nihilism says I should quit now.
We don't have a lot of time so we try to make the most of it.
I am impationt because I life only 80 (notmore even 40 from now) or less years, and want to see it.
And I am sick of the lame progress our money and profit greedy civilisation does.
I feel betrayed about my future. (Yes sorry the oney who were born before 2000 had other ideas of how this century would go than it does now).
The most terrifying answer to the Fermi paradox is the “Alone in the Dark” solution. There is no life out there, we are a true anomaly. This scares me when I think about it because of the implications.
“Two possibilities exist: either we are alone in the Universe or we are not. Both are equally terrifying.” ― Arthur C. Clarke.
Or it could imply that god created the whole universe for our planet and we are truly special. Even though that is more comforting it’s also kinda boring.
@@lawrencetrujillo7365 This is hopelessly naive and conceited.
There's a worse possible answer. Whatever killed off all the other life in the Milky Way galaxy simply hasn't gotten around to dealing with Earth yet...
😳
@@charlestaylor253 There's a low chance of other life in our galaxy. But there are an astonishingly large number of other galaxies.
Imagine a box with insects that live on the bottom of the box. Now, imagine another group of insects that live on the roof of the box. Now consider if neither group of insects were able to look up or down. They could be inches apart and never know the other existed. I believe that there is probably life, but we just haven't got the ability\knowledge to look in the right direction.
The way our governments keep secrets from us, we would never know if aliens ever contacted us.
lol. Govs are leaking secrets all the time. They're not good at it. At what are they good at, btw? Appart from squandering hard earned money?
Do you really think if aliens were here they’d ask trump , or any other so say leaders permissions to show us their tech or whatever it is they’d want to do, 😂 ?
I find the most likely scenario is that life is wide spread through the Universe, including our local galaxy, while intelligent life is more limited due to the complex requirements involved. It's highly likely that the few other advanced civilizations that currently exist in our own galaxy have placed Earth in quarantine after receiving our radio transmissions, or visiting directly, and deciding humans are nuts...
We are like monkeys throwing poop to visitors.
Curb the thinly veiled mysanthropy there. By what metric can you conclude that Aliens would deem us as monsters unworthy of contact when you don't even know how Alien civilizations are like for sure? They might very well be as bad or worse, far worse than us...or more advanced and empathetic after going through similar or just as rough phases as us, enough to make it conclude that our state is totally understandable given the conditions of our scarce world, our genetic heritage as primates and our age as species.
They may deem as in a similar way to how we deem hose pacific islanders who have been isolated in the ocean for millenia, those who roar at boats and helicopters: leave them alone, they act in a totally understandable way considering how little they still know. Lets leave them be free.
Agreed
Lmao especially nowadays 😂
We’ve only have radio for a little over 100 years, so civilisations within only 100 light years would have detected us. That’s very close in cosmic terms and probably too close for another civilisation to exist
The Fermi Paradox can only be fully answered when we have the right technology.
Prove it.
life is just super rare bro... maybe like once every local cluster or something. and we will probably turn this planet into a nuclear wasteland so... yay
There was never a Fermi paradox. By the time that theory was put forth our government was already well aware of aliens visiting our planet, and that they had been visiting for a long long time
@@kevinroux8856facts
I know aliens are out there billions of them , yes they might not be intelligent as humans today but ancient Egypt intelligent aliens are a much higher possibility I hope you understand what I'm trying to say. Unless we have technology that can prove other worldly beings then even I cannot say they exist or not .
I personally believe the great filter theory, but I think the filter where dna and rna need to emerge is the hardest step
Dude, what prompts did you use to generate such beautiful images?
Learning about geology makes me think that life should be somewhat common. I like the theory that there are one or more advanced civilizations that are aware of us, but remain silent because they see that as the ethical thing to do. A civilization needs to survive the great filter on their own, otherwise, it's no better than a pet.
If they have the tech to reach us, one of them will have done so. Even if it is illegal.
Fair point. @@slaapt

Well, they would if they even think like us, or any have the mindset to do what they would consider "wrong".
On Earth, humans are the only living organism that has any sense of right/wrong or morals.
Everything else just does as it's DNA programed it to do, and what they are feeling in the moment.
Who's knows if aliens would be like us, or like the animals...just smarter.
I really like this thought as well. The sink or swim is both terrifying, yet motivating. Thank you for sharing! 👍
Prime Directive
What if we have encountered aliens in the past, but we were too primitive and just saw them as godlike beings? The aliens made some notes like all scientific explorers, penciled in a repeat visit for a few thousands years in the future, and moved on to the next system. Everyone assumes they would visit since the 50's, but the sheer distances might mean their visits occur in the thousands, or tens of thousands of years.
You should study the mythology of the Dogon tribe.

@@mrb2349 or research. It's quite entertaining.
Well said.
Very possible
Back in the mid-1970s there was a book entitled “Habitable Planets For Man” which attempted to solve the Drake Equation with values that we now realize were insanely optimistic, and its best guess was that the nearest galactic civilizations would be about 1000 light years away from each other. This implies that it would be more like *5000* light years apart. Far too far apart to be contactable.
It's unknown how common it is for life to spark. We have only 1 Datapoint; therefore, it's impossible to extrapolate from that...
I like to think they're observing earth like a reality tv show. It's kinda cringe on this planet if you think about it. They probably can't stop watching.
Did you see the South Park episode where the earth show was going to be cancelled because we're too boring?
They may find our species to be self-destructive and, therefore, too dangerous to interfere with.
We might, at some point, be unceremoniously wiped out just because of that... if you want peace, prepare for war. But even when we have peace we still find a reason for war so.... antimatter bomb or genetics targeting virus?

@@simplygreen5832 I know it's crazy!
Yeah it was said in the video =P.
Our behavior might be regarded as us just being "human". Its kind of like watching a lion tearing a zebra apart, but we don't interfere because it is "nature's balance". Interfering in our affairs would be like removing predators from a particular biome, watching while the herbivore over-populate and then starve to death. They may see war as a natural "culling".
They may see all life on earth is being one organism and humans as just another, temporary, expression of that life-form -- among many others.
10/10 video.. I've been watching these sort of videos for years and no matter what I keep coming back to this one and I am more and more fascinated everytime! Exicuted perfectly! The clips the narration and the theory are mind blowing! Thanks destiny, the thought that AI takes over in the near future and starts colonizing the universe but only to collapse yet it has started a simulation to see how it was created and where it went wrong? Absolutey mind blowing haha 🤯🤯🤯
One factor not included here, which comes out of all the exoplanets we're discovering, is the apparent rarity of rocky, earth like planets. The odds of advanced technological civilizations seems to be even slimmer than we thought.
Like most complicated phenomenon, it's a combination of factors: 1) we are early 2) not all intelligent lifeforms reach an advanced technological level or they last only a short time until they destroy themselves 3) the distances are too big compared to the speed of light which makes it difficult to detect others 4) some choose to stay silent.
It's very well possible that as we speak some advanced civilization somewhere in our galaxy is busy expanding to other stars but we can't see it yet.
My thought is 110% that we are very early. The universe is an infant when you consider how long it will be around. Life has taken a significant potion of the current age of the universe to become complex at the level of humans, and before that it took billions of years for the Universe to reach stability to allow this life. Give it a couple billion years more, then we can start worrying if we find nothing.
Or perhaps we haven't thought far ahead enough. Suppose an advanced civilization in our galaxy started colonizing the galaxy 10 million years ago (or earlier). Then they could be ready with that already by now. However, does that mean they (would want to) have inhabited every habitable planet within it and turned every star into a Dyson sphere/swarm? In other words, would do have any desire or need to be so visible? Maybe not and they would choose to put virtual worlds of themselves (in AI form) in supercomputers on a couple of billion of rogue planets or asteroids. That way they would be distributed on a massive enough scale and hard to eradicate or even detect. For energy sources these supercomputers could use maybe just fusion, some form of energy from the planet/asteroid, or some other energy technology that we don't know of yet (so not Dyson spheres/swarms). In this way multiple different civilizations could coexist in the same galaxy without bothering each other much.
@@Skadders It would be both interesting and terrifying if we were the so-called "precursors".
To put the "silence" into perspective, even if the Milky Way contained A MILLION advanced civilizations, it's STILL likely that the nearest one would be too far away to communicate or travel to us. This claim from an expert, not from me. The vast distances of galactic space are inconceivable to the human mind.
It's more likely that intelligent life is so rare that only one instance of it exists at any one time in a universe like ours, but if multiverse theory is correct, time is irrelevant.
In theory, there’s another solution to the Fermi paradox: you can’t go faster than the speed of light, aliens are everywhere but they’re exclusively on their home planets and haven’t ever left, we havent met aliens because they’re enjoying living on Omnicron Persi 8
Exactly. They are content with this amazing life and don't feel the need to go elsewhere.
I don't know why everyone assumes that faster-than-light travel just HAS to be possible because Einstein said it was. Einstein got a lot of stuff wrong: the Cosmological constant, the importance of gravitational lensing, his gravitational wave formula that someone else had to fix. Too much television, I would bet.
@@donnewton7858 There is a kind of inevitability to the progress of intelligent life. The Wright Brothers didn't 'invent' the airplane, it was an idea whose time had come. If they had been killed in a car crash, someone else would have done it, then all of the following aerodynamic advances. The discovery of fire, chemistry, electricity, transistors, radio waves, nuclear capability, all was inevitable. Any (most) advanced race will eventually reach a point where it is capable of wiping itself out. Because of this, only races that progress spiritually enough to not want to kill can survive for long after the technological revolution. The others, if maintaining the desire to kill, will self extinguish.It's a kind of built in safety net for the rest of the Galaxy. Pretty soon any kid will be able to make a weapon of mass destruction. So that means, that only races that don't want to conquer the Galaxy are still alive. Just a thought .. ;-)
@@donnewton7858Why everyone assumes faster than speed of light is impossible is because the postulate of Einstein's theory of relativity, which is that nothing can travel faster than c, when they do the "what happens to the world" math based on this postulate, it worked with everything as it should for the vast majority of things; it even predicted black holes before we knew they existed. It isn't just because some German smart man said it was the limit, it is because nobody managed to disprove it to this day.
@@eeriemyxi Ah, science, the search for a way to prove things wrong...
It's possible that if we ever came in contact with aliens, those aliens are actually future versions of ourselves who have discovered FTL travel. It would only make sense that we would be the only species interested in our own planetary system given the vastness of the galaxy/ universe.
You’re always looking in the wrong place until you find what you’re looking for
I find the hypothesis in the fictional book called 'The Three-Body Problem' by Liu Cixin very interesting - where the silence from us is very advisable :) Also the radiowaves we have sent during the past 100+ years are so weak that they are not interpretable anymore even in the neareast star systems. Both topics are partly discussed below way earlier, posting just to support those comments. Excellent video again, thank you.
i like that book, but i don't agree with the theory, mainly because i think any civilization beyond type 0 should no longer be bothered by scarcity, and should be peaceful either through genetic engineering or evolution.
Keep on arguing and analyzing the Fermi bollocks. What nonsense you people are stuck in ?
Exactly, everyone forgets the inverse square law, after a few LY, Earth would be indistinguishable from the background radio noise of the universe.
Hopefully the Three-Body problem books were good in their original language because they were pure crap in the translated English.
@@rosmith51 I read them in german. They were definately not as easy to read as native german books or translated ones from English but still interesting enough. The difference in grammatical structure makes the translation between chinese and romanic languages had and unelegant
I used to believe life would be more common in the universe. It seems conditions in our Solar System are even more unique than we thought, the Drake Equation seems to have more factors to consider, like having a large Jovian planet to sweep up rogue asteroids/comets, having a large stabilizing moon (otherwise seasons would run amok making evolution difficult and maybe the tides our oceans helped stir things up in an important way in life's early days? Our atmospheric composition, minerals present in our crust (imagine if lead/mercury/arsenic were even more common, biochemistry might be impossible or severely handicapped?), we aren't close to clusters of dangerous neighboring stars, our Sun's neighborhood in the galaxy is very sparse and seems be be in between spiral arms. Our Iron core (and magnetic field), blah blah blah....
Not claiming life elsewhere is impossible, but just could have far more hurdles and filters than us.
I agree with you. After watching all those documentaries, it feels like our solar system is an anomaly compare to other sytems discovered.
I think about all these factors every other day and it's mind boggling all the things that seem to have helped life evolve but then I think about the whole life finds way JP quote. Maybe life just needs a couple of angles to work with
I rather think that other form of life call for completely different chemistry and building blocks.
@@MrMirville It's possible, some have postulated that instead of Carbon based life, Silicon would work. It's carbon's flexibility that allows it to form complex chains and compounds that allow the storage of energy, rigid structures and gasses to react in meaningful ways. Biochemistry was a fun but very difficult subject in college for me. However, even if Silicon was the basis of life on some remote planet, I believe hearing that Carbon would be incredibly toxic since it would compete with it and inhibit it. Carbon is extremely plentiful in the universe...
Or perhaps we are part of the purpose the universe exists at all. Quantum fluctuation => free will. Conscious observation => wave function collapse. Mitch, Australia.
The scariest thing about the great filter, we dont know how far the next one is, if there is another one, or if weve even passed the first one yet.
I am personally the proponent of aliens seeing what we are doing to ourselves and be like "nope, ima outa here, dawg!"
The speed of light is very limiting factor because distances are collosal, and I strongly believe that many advanced civilizations exists in our galaxy, but they communicate with something like "Sub space" comunications, which we can not detect (at the moment) maybe they communicate a lot and form something like "galactic federation" but we can not hear or detect them...
Your theory is flawed.....cause you only thing some sort of Starwars type 2 civilazation some 10.000years into the future from our perspective.
What about civilazations only 200years more advanced or 500years or 1000years.....where are their radio emmissions??
@@jordanorfanopoulos6697 in 1000 years radio signals will be like smoke signals are to us now.
That type of communication is happening on Earth right now. Infrasound. Elephants "talk" all the time and almost constantly but the frequency to too low for us to hear. It's quite possible they can't hear us and we can't hear them. It's also possible sound and sight aren't they only ways they communicate.
Agreed
@@jordanorfanopoulos6697Perhaps they don’t use radio to communicate. Maybe they’re a telepathic hive mind. Maybe they don’t have ears, and communicate with smell only. Maybe they only communicate through a sense that we don’t have.
Until we meet another life form not of our planet, we’re trapped by our own hubris.
The Zoo Hypothesis makes the most sense to me. It certainly explains why there are so many U.F.O. sightings and yet we have not made contact with an extra terrestrial civilization.
We are being observed, and interference by these creatures is very limited.
The UFO sightings are just military drones, It's why 90% of the sightings are in the US and the UK.
If they were out there and that advanced we wouldn’t see them
Every one has his unique hypothesis where as real fact we could possibly understand millions of year later.
Zoo, 1st Directive or Death/Prison Zone under total lockdown and communication blockade is my favorite solution.
Imagine we’re a tourist attraction and they’re here taking pictures with great big signs saying don’t feed the animals
When you consider the size and continuing expansion of the universe, I think that the writers of Star Wars got it right as well the writers of Star Trek.
My theory would be that our understanding of physics or the law of the universe is still very primitive, like we’re still a three dimensional being while they’re all at a higher level. Maybe using frequency waves to let out signal isn’t working because it is too outdated or they’re just using unknown form of energy to communicate which is why it is missing for us. Sounds ridiculous but who knows they might be using magic or something similar, the astrology folks could be right all along 😂
Seems to me it would be a 50/50 chance like Arthur C. Clark said "either there is life in the universe or there isn't and both outcomes are equally terrifying". The ai sounds like the geth in mass effect
It's 50/100
I'm under the camp that thinks they're here already but aren't making a big show out of it like showing up on the lawn of the white house with enormous rattling metal ships or whatever. They're carefully watching in the background and contacting only a few rare individuals that are worth taking a look at or having a chat with. They are intelligent enough to know making a giant public appearance would disturb the already fragile balance of our species at this time. We're collectively not ready to meet them yet. When we grow out of our mental infancy they just may show up but not in the way we think.
People 1000 years from now: "Can you believe people used to think the Fermi Paradox was a real thing? 😂"
I think corporeal life is just a phase we have to work through, to eventually unlock consciousness without physical form. That's why advanced civilians before ours aren't sending out archaic (by their standards) physical signals.
I agreee if we can find a way to unlock our consciousness we would realize we are part of the universe as just energy and that our consciousness projects this physical world
One reason is that multitude of civilizations do not follow the same chronological timeline (which is obvious), therefore, we may be missing one another due to being at different stages of technology.
Example: someone sent a signal to earth when the dinosaurs were alive. There IS life, but no one to perform intelligent communication. This aspect may actually be the most common issue.
However - I do have a thought that localized stars that belong to the original birth place of a civilization, may share certain chronology that could make their timelines in some way similiar.
When you think of how perfect the conditions would have to be for us to even be here is astonishing. So in order to question if there are other life forms out there would have to be other perfect conditions to occur to form life. I believe there is life out there but some are ahead of us and dont want to deal with us and some are maybe not even formed yet
Interstellar communication is probably done at the quantum level, because it would be instant and distance does not matter. Something we have not achieved yet. The size of the universe and the number of galaxies, stars and planets completely negates any possibility that "we are alone" in the universe. we may be alone in our galaxie,but even then, the galaxie is so massive, it's really impossible to say with certainty "we are alone" in our own galaxie. it's more likely we are not privy to galactic communications,because we don't have the tech yet.
Something to bear in mind is that, even though we've been emitting petawatts of radio signals for 100 years, most of them are actually of very low power. The astronomical distances they have to cover means that any listener would have to have ever larger antennas to collect the energy enough to raise it above the cosmic background noise. The same is true of us listening. There may be lots of radio chatter going on from alien worlds, but until we build a big enough antenna to collect enough signal to parse it out of the noise, we would never hear it.
What astronomers have been listening to and hearing are cosmic/astronomical events that are many billions of times more powerful. Aliens simply aren't going to generate that much power to use to send messages between themselves or each other.
Then there is just the scale of the universe. If there really is no way to go faster than light speed (the speed of causality, btw), then it just isn't feasible to "go visit the hyoomans".
All that said, I have no doubt that there is other life out there, perhaps even intelligent life, but we're well enough isolated from it and it from us, both in terms of exchanging messages, and making visits.
FTL is not necessary, sublight speed is enough to visit nearby systems, and even colonize the entire galaxy(in forms of AGI at least, ala Von Neumann Probes).
They should have already been here, imho, what is the great filter is maybe economic interests, the global catastrophe is imminent, but both the elite and leaders aren't giving a single damn to it, because alternative energy sources to hydrocarbons aren't profitable enough, or just aren't interesting enough(nuclear, solar, wind, geothermal, batteries).
And the greenhouse effect will keep rising the global temperatures even if we suddenly stop emitting greenhouse gases today, for an extended period of time of hundreds of years.
That may mean we are all doomed to collapse due to the carelessness of the 1%.
I believe the answer to the Fermi Paradox is this: Matter in the universe, in any form, even pure energy, does not actually exist unless it is detected by conscious life. The more advanced the life, the greater details can be seen, and only in that instant does it become solid and real. All physical events to explain any object or event only exist to the extent required to explain our observations. In other words, the universe is designed to be discovered, and the more conscious it becomes, the better it can fulfil its purpose :)
Your explanation aligns with quantum theory, may be we are not advanced enough to manifest aliens
There’s also the fact that other advanced life forms may be living in higher dimensions that we can’t see or even understand: Not seeing doesn’t mean there’s nothing.
People also presume the inevitability of external exploration. It could be the case that civilizations after a point, turn toward inner exploration.
There also might have been a general war which eradicated every advanced civilization out there, either annihilating them, or reducing them to the point where they either don't care--to busy surviving--or are unable--tech-fall--to reply.
Or, A) The heliosphere blocks whatever signals space-faring civilizations actually use.
B) We are currently unaware of the transmission mechanism used by space-faring civilizations.
C) Space-faring civilizations are currently deliberately preventing signals from reaching us.
I think we would have detected some form of artificial signals sent from these "advanced civilizations" in the past.
If there's ever been such advanced civilizations, they'll probably leave some form of artificial signals that now float around the universe.
You don't need to go that insane. Yeah, there is a lot of real estate but how long can advanced civilization exist? Let's say 1mln years. It is really easy to miss all or vast majority of civilizations simply because they evolved in older parts of our galaxy and simply died already. And their planets were unable to evolve another highly intelligent species because 1st species used up all easily available resources. There are also magnetars, stars exploding, rogue planets/stars/black holes. And the closer to the galactic center you get the more likely you are to get smacked in the face with deadly burst of radiation.
A Galaxy-wide war would be impossible, because Science.
The great filter is what that is called.
After reading the Remembrance of Earth’s Past (book trilogy that includes the Three Body Problem), the reason we might not have encountered life could quite possibly be based simply on the Dark Forest Theory with which author Cixin Liu proposed in the second book. It stacks on the Fermi Paradox. It can be explained that for example, our civilization is like a child in a dark forest crying out and our cry might reach a malicious or benign civilization that is either capable or incapable of reaching us, however if so that they can we would not know with which category the incoming civilization would follow. Or they could choose to treat us like a Gachi game and we just happen to be a poor character to be recycled 😂
Two possibilities exist: Either we are alone in the Universe or we are not. Both are equally terrifying.
@@DoomFinger511 one of those possibilities is an impossibility. The fact that life exists, is proof that other life exists. As for “equal to or greater than human intelligence” is arrogant in our understanding of what life is and create false expectations. Whether we find life that is as capable as a human or as capable as an amoeba on another planet, it means we are not alone.
@@iansexton2259this isnt correct i think. In forensics, just because you can see a footprint in the backyard doesnt mean that there is a footprint in the bedroom which is kind of what you're assuming.
I don’t see how the forensics analogy applies. We have concrete evidence that molecules of life exist on other planets and we have concrete evidence that bacteria or microbes exist on other planets within our solar system. I mean a bit of Schrödinger’s cat does apply that we cannot determine without investigation if life exists on another planet, but that’s what science is, investigating and attempting to solve problems. If a microbial discovery is not defined as life then to some extent the masses of most nations due to the education system are unliving lmao
The fact that each planet has a unique composition could also mean that the life on each place is different therefore we cannot recognize each other because we are physichally different and what we see when we view the universe is different ...like how it was heard for tribes to communicate until common languanges were created
I've always detested the Fermi Paradox. Us sending radio waves into space expecting aliens to hear us is like a french man shouting on the shores of the Atlantic ocean expecting americans to hear him on the other side.

i think they are talking about the human mind
telepathy is faster than light, it's just you are not able to tap into the realm of the subconscious mind, yet. Telepathy is real.
some say within the subconscious mind there are doors/portals that you can go through to enter another dimension. the key to this universe is within are own minds. but you are too busy staring at your phone to ever evolve to this level.
the people in the comments are most likely rejects of society. especially investifativeoutcomes. this guy going around trolling nonstop.
I think you forgot to mention the theory about the advance civilizations evolving and leaving this dimension and going to a higher dimension that we could never think of at the moment. Hopefully something like a warp drive or wormhole teleportation sh*ts can be invented in the future or space travel will be a lot of sleeping or maybe living in a ship your whole life.
It's entirely possible that we lack some biological factor that would make alien communication readily visible. As an example, recent studies have revealed that certain birds and bats might have a sense for magnetism and it's suspected that quantum functions might even be involved.
We've known for a while that many of our senses are frightfully average.
This makes the most sense to me..
I honestly think that (as frightening as it is) we are the great old ones. Civilization is out there, but we're all young, so our radio waves haven't reached each other, yet
That’s called the “First Born” solution to the paradox. In a finite universe, some life form had to be a precursor race to reach space before anyone else. We could be that precursor.

When you consider that stable galaxies formed 1bi years after the BB (13 biy ago), that Earth is only 5biy old but life is here for 4bi years (right after Earth' hell phase ended). Also, intelligence is just a byproduct of life. We just can't be the old ones. A million years is nothing for the universes age.
Aliens from space have seen how we act: how we treat each other and our home, and even though we don't all act that way all of the time, they know enough to be very, very cautious with any plans to approach us. We can be dangerous and toxic.
I believe that if an alien civilization is advanced enough to have "seen" us, they probably won't find us dangerous.Toxic? Yea. And a bit sad. But I think all advancing civilizations go through what we are. They either learn and advance or go extinct.
You assume that they would even have a metric by which to evaluate us in those terms. An alien civilization could differ from us so substantially that we wouldn't even understand their opinions on anything.
You also seem to assume that any civilization out there must be better than our own, which seems rather arrogant as it implies you believe nothing could possibly be worse. Considering how many Earth civilizations have been worse than anything you've likely experienced, I think it's just as possible any alien civilization would be worse than our own.

There's a good and bad side of any kind of civilization or animal species.

Thats boomer mentality, stemming from the times of Vietnam war. In reality I dont think it makes any difference nor they care.
Entanglement is a good way to overcome time and distance problems in communication.

I love the idea of wormholes and teleportation from where any alien civilization can enter in our solar system via any ray or charged particles like lightning..If any technology had already developed so humans are nowhere in terms of technology and improvement...
Howard the Duck.
I was looking for a comment like this. The idea that a controlled "wormhole" or "portal" through what are called "space-time" is probable or at least possible then challenges all of what humanity has collectively concluded thus far about such things. The rub is this: such notions were considered well before any technology on Earth was even capable of being launched extraatmospherically. It makes one wonder if encounters haven't already occurred, such as "the gods". The reality is that no human effectively knows more than a one-millionth of a pinhead about the galaxy, let alone the entire cosmos. Seeing ≠ experiencing. At the rate humanity is going, it will make itself extinct before such possibilities will ever be known. That may well be for the better.
We’re assuming that other civilisations have the same desires and compulsions as us, even that they have desires at all. Maybe they aren’t bothered to explore the universe, or engage in communication.
Human beings have two fatal flaws, greed and tribalism, that's going to make it difficult for our species to advance to the point of interstellar colonization before we destroy ourselves and this planet. A species that would become as advanced is what we see from Hollywood when aliens are typically depicted would require a species that didn't have that flaw and could work together for the betterment of the whole. Any species that could operate that way probably wouldn't invent capitalism, so they may not have the desire to conquer the universe, especially if they have all the resources they need in their own system.
At the end of the day, it's a race between evolution and a planet's resources. If a species can develop sustainable unlimited energy before using up it's non-renewable resources, then the sky is the limit. If not, any species that advances will return to a primitive state once they hit that wall. Humans will hit it within the next 1-200 years if we don't change course.
Those scenerios do not take into account on whether or not an advanced extraterrestrial civilization actively take part in other less advanced civilizations, keeping themselves basically separate yet engaged in the developement of the less advanced civilization. Maybe they like being just watchers and guides and have and do interact yet on a level that We are not awared of.
I think that we forget a very important concept - not all civilizations will be able to rise to the level of electromagnetic technologies. Resources. What are the physical resources necessary for certain technologies to evolve? There may be low iron and low copper planets. They may even be considered rare metals on those worlds. Yet they may produce high resin technology cultures advance enough and even surpass our "cultural" world without ever being able to reach wide use electromagnetics technologies. And, thus not wanting to expend such valuable resources on contacting other other civilizations. Since we are running low on our own resources and we yet to reach solar system level civilization. Like "us" we have budgetary conflicts constantly in our government whether to continue our space research.
Another is biological catastrophes. like our last pandemic. Or ecological tragedies, such as world wide volcanic disasters. We have been very lucky to have survived such catastrophes but always with the lost millions and one day we may not make it.
I hope we don't meet aliens from another planet, look how we treat our neighbors on this one.
If aliens do exist, and being super advanced and intelligent, they view us like cockroaches.
@@standforhumanitariancauses4756we are always assuming they are super intelligent and advanced lol they might just be a stupidier version of the island boys, who knows (if they even exist)
My personal consideration, is that how likely life is to take hold needing many heavier elements to form complex life, then again the need for even more heavy elements and metals for that life to develop civilization, then the even greater demand for rare elements for advanced enough civilization to reach into space. And considering how those elements are only created in relatively small amounts in super novas, and going back further in time they would become even more rare, I'd wonder if the proportions of heavy elements, necessary for advanced life, have been present long enough for many other civilizations to exist or advance enough to reach out into space. Given that they require so much to make???
Advanced civilizations aren't using radio for communications.
We've been using radio since the1890's which might be replaced in the not too distant future by quantum entangled particles. So lets says 500 years from radio to quantum communications, that's a pretty small window of opportunity for detection.
Anyone ever have the strange idea that space as a divider could protect against interstellar wars between species ?
It's a weird plan, but only relatively small vessels can traverse the journey between stars, and with that attacking a planet becomes useless, as any vessel that would traverse the distance would be no match for the local economy. It feels like a plan, brilliant.
A good sci-fi book to read regarding why we may not find alien civilisations is Stephen Baxter’s Galaxias. Quite an interesting read
Maybe physics changes so much more than we think it does based on gravity. And other species are unable to hear each other bc of interference from differences in physics
Valid point
I think the basic laws of physics are the same everywhere in our universe. If aliens are experiencing a different set of laws of physics then that means that they are living in another dimension or another universe and that would make them even more alien than if they were from another planet.
@Zurround there is absolutely no evidence to support that. However there is alot of evidence to show that Air pressure and gravitational and electromagnetism change how physics works. Hence a super cooled electromagnet floating, resulting in the use of bullet trains. We don't know what a different sun could also provide to physics. It isn't a different universe, it's just different parameters. Thusly preventing life from forming and many other things we don't and can't understand. A deeper understanding of gravity is necessary to know more.
@@Zurround physics changes alot based on a variety of factors. Gravity is just one of the things that can influence it. There is a very high likely hood of a primordeal blackhole at the edge of out solar system that would skew any observations made thru its gravitational lens. If it is there then our entire understanding of the universe is invalid. For insteance entropy or the slow expansion of the universe was only discovered becuazewe obsrrved disteny objects slowly drifting apart. That could just be the primordeal black hole slowly getting larger. The rate at which time flows can dramaticly change the laws of physics and we kniw from quantum fields that gravity isnt the only thing that effects the flow of time. High density magnetic fields can also create dilation effects. Your understanding of physics is outdates by about 25 years. And is very simplistic.
@@Trollkin9000 I maybe misunderstood. I was thinking of DIFFERENT LAWS OF PHYSICS. That might be the case with another universe or dimension.
My own theory states that while there are myriad intelligent species in the milky way galaxy, we are unable to fraternize with each other due to the vast distances involved between star systems. The distances are too great to allow communication let alone travel.
So, while we aren't alone, all of these intelligent species scattered around the galaxy may as well be. There is no way to communicate with them nor even confirm their existence.
Possibly we need to master quantum communication, as radio waves are like yelling in the jungle
If they’ve watched mankind for any length of time, it makes sense they wouldn’t make contact. We destroy everything especially what we don’t understand.
The one thing that the Fermi paradox doesn't take into account is how a civilization would react to contact from beings probably way more advanced then are own, in that scenario I postulate that civilization leaders as a whole would try to keep it secret if for anything to keep us calm
it wouldnt be up to them.
Secrets can't be kept.

One thing I've not seen considered- or at least not seen considered loudly or prominently enough for people to really talk about it in publicly available places like youtube- is the idea that communication via electromagnetic waves across interstellar distances just isn't really possible.
If you think about the truly extraordinarily vast distances involved, then compare it to the amount of literal energy that goes into something as simple as a radio broadcast, it becomes readily apparent that any kind of signal would very very rapidly degrade and thin out as it expands in a spherical radius outwards from the point of the broadcast. Even across such a cosmically short distance as a few lightyears, the strength of that kind of signal would rapidly fall beneath that of the cosmic background radiation still floating about from the big bang and which is constantly being scrambled by the literally uncountable number of stars in all existence. Every single bright light is a massive amount of emitting radiation, and there are almost as many of them out there as there are grains of sand on planet earth. Each of thing pumps out more raw, unfiltered Em waves than any transmitter humanity could ever possibly hope to make.
The idea that we could just blip out a short packet and expect it to be noticed at all- let alone received, interpreted, and understood, is frankly ridiculous and utterly laughable. It's entirely possible that we've been "receiving" the ancient radio signals of long-dead civilizations in their nascent technological eras for centuries or even millenia; and have just never been able to notice them simply because the only thing we "get" from space is a massed jumble of seemingly random static. Just like when you tune your television to a random unused channel and get nothing but static, or when a thunderstorm overhead intereferes with a wifi signal. Something so small as that is enough to block phones and satellites- but space has trillions and trillions of radioactive meganukes just floating around. The only reason we can use EM communication at all is thanks entirely to our planet's magnetosphere deflecting most of it away, but once you go past that sphere? Good luck. Even the satellites we send to explore the outer planets struggle to communicate anything more than fuzzy images or very simple number streams across those distances which are cosmically equivalent to the gap between two nosehairs.
Another reason is that the inverse square law ensures broadcasts get weaker the farther they travel. In time our signals will be swamped by interstellar noise. So a sphere exists around earth where no signals can be detected. I read somewhere that receivers near Proxima Centauri could not detect any radio signals from Earth. Fermi paradox solved!
Can we presume a intergalactic civilisation like the Federation in Star Trek, and they are guide by some directives that for making contact the civilisation had to have light speed capacities... Like the prime directive... They observe us "incognito" .... Will it be possible? I think so, did they already make contact, i think so too.
For space colonization, the planet should also have some form of flying creatures to give the intelligent creatures the first idea of being able to fly to space. Then, it should be also one that's not tidally locked to it's star, so it's creatures could see in the dark, seeing other starts.
Dream on! 😆
@@iloveitall what? I only added few more limitations that some other civilization could have, if existed.
@@IlmarKiisk Space colonisation is fiction. No species will ever make it.
Any idea how long a journey to Alpha Centauri would take?
Also low enough gravity to be able to leave the obit
Anything flling will give rise to the idea of flight. Simply because some things fall slower than others, someone will go "I wonder if I can get it to hang still in the air." Which is easily solved once people notice hot air rises.
It not being tidally locked is also irrelevant. Planets are round, ao if the condition is "they need to see the stars" they can. Just move a little bit. And on a tidally locked planet a lot of the people would likely live in the twilight band anyway.
If intelligent life were able to communicate telepathically or in other ways like animals seem to, then they may never have the need to invent radio communications in the same way we do. We've only understood the radio spectrum for a hundred or so years, but there's probably lots of other technology we just don't have yet. Its like trying to received hd satellite tv on a crystal radio... you wouldn't know what you were receiving it would just look like noise.
Maybe they have a standard like maybe we have to figure out how to contact them through some kind of quantum entanglement???
Another idea: Because there is no way to support a large civilization across the universe just because of certain constraints like the speed of light being the limit of speed, all alien species turn to virtual reality(if they survive the great filter in the first place), and create a virtual simulation in which their species exist in a perfect universe.

It isn't simply impossible - we don't even have any real clue how we came to Life. Without that understanding, it's not possible to say what sequence of events or what order they had to happen in that made Life possible.

We have no basis, whatsoever, on which to determine there is any real possibility of another example of Life. We have one example, and we don't actually understand how it emerged.
That's not enough data to determine anything. We can only talk about probable this and probable that, on that basis - but that's our business: it's actually meaningless nonsense. We can't say how probable other Life is, because we actually can't say how likely it is there is any, because we don't know exactly what's required for it to exist.
That we exist, is evidence only that we exist - it not evidence that anyone else exists or should exist, just became we expect them to.
What we expect is nothing to do with anything and - while that's the case - it's actually just as probable that we're alone out here, as anything else.
If an advanced civilization exists, they could already be among us and we wouldn't know it. A civilization even a thousand years older than us could possess the technology to cloak themselves and blend right in without us being able to detect them. With all the ufo sightings we have been experiencing, I`d say they're already here and have been for a while.
Agreed. I personally think that advanced aliens know about this rare, living planet and have explored it, at least with probes if not in person, for thousands of years or perhaps even longer. There is some notable evidence of this gleaned from the myths of several civilizations from our ancient past.
A thousand years older 😂
A. Clarke, "any sufficiently advanced technology will seem like magic to those less advanced." Going back 1000 years, this is comprehensible. There could be an older civilization on earth, there may have been other intelligent species. Maybe. Not necessarily probable, just a maybe.
Good point. The fact that people believe the government is harboring a 'crashed' vehicle or vehicles is ludicrous. Imagine, if you will, a civilization so advanced that it has been able to come to Earth. Now try to imagine such an advanced ship 'crashing' into or on our planet...they come all that way just to 'crash'. Yea, right.

The Malkemus Paradox: for every issue humans solve, two or more new issues emerge.
Looked for a microsecond, couldn't see anything, concluded we're alone. - The Egocentric Being
The distances, even in LY, are so huge it’s hard to figure. But one thing is sure: nobody in the universe can move too far from where they’re from. Even at LS, which is impossible, it would take forever to go anywhere. And even then, chances of finding anything alive once you get anywhere, is slim to none. We’ll go extinct before we ever see anybody else.
Not to mention there may only be one INTELLIGENT species per x number of galaxies, and they may have existed millions of years before or after us. Only way we’ll ever encounter advanced extra terrestrial life will likely be wormhole travel, which has its own plethora of circumstantial conditions that make it seem unlikely, if even feasible, hypothetically. Given the implied rarity of intelligent life, the nature of time proves even more limiting to any hope of ours in meeting another intelligent species than even the scope of space. Perhaps only once in billions of years do civilizations as advanced or more so than our own occur in nature… think of how unlikely the Theia collision was, which created the moon, put it in geosynchronous orbit, and gave the earth its dense metal core and magnetic field, and tectonic activity. I digress.
If you could travel 25% the speed of light you could travel for thousands of year on earth but only 10 or 20 years for you. Because time slows as speed increases a ship going 99% the speed of light could make across the universe within a average life span.
And if you try to do mind uploads to circumvent those problems: we may find how closely our consciousnesses are tied to our physical bodies.
The Milky Way stretches between 100,000 and 180,000 light-years across, depending on where you measure, which means a signal broadcast from one side of the galaxy would take 100,000 years or more to reach the other side. Now consider that our species started broadcasting radio signals into space only about a century ago. That's represented by a small bubble measuring 200 light-years in diameter surrounding the position of the Earth. For any alien civilizations to have heard us, they must be within the bubble.
Exactly!. I've been telling people this for ages. Light speed is faster than anything ELSE that moves, but slow relative to the vastness of the universe. If we could somehow move at 25x the speed of light, it would take us 1000 years to get to the outer edge of our own Galaxy. Interstellar travel in any sort of reasonable time frame requires moving so far in excess of the speed of light that we don't even have a proper concept of how to achieve it. Our best guesses come from stuff like Star Trek. Wormholes and warp fields, both of which are things we can't prove to exist, can't begin to figure out how to create, and have no idea whether or not are even possible.
TL;DR, us thinking there are no aliens cause they didn't come here is like a microbe on the other side of the planet not thinking a single-cell microbe on the other side of the planet thinking no microbes exist on this side of the planet cause none of them ever go visit....
As for the AI premise, the AI recreating a civilization to see why it failed, I read a book many many years ago that covered just that idea, with the AI recreating the civilization in a simulation, going over different stories and outcomes again and again. I wonder if that's where those proposing the AI premise got their idea.
That's the basic premise of No Man's Sky, a game by Happy Games.
Again, we cannot even imagine what an AI civilization would do, we only know the impulse of biological animals like ourselves, reproduce explore conquer acquire etc so we can suppose that other sentient biological lifeforms however alien might act in a similar way (to a policeman everyone looks like a criminal) but what about "life" like AI that does not grow old weaken and die, that cannot suffer pain that has no loyalties no attachments no desires no feelings? Assuming to even guess at it's motivation would be the height of human-centrist arrogance.
Sending a beam from a sphere would take infinite amount of sorceress to make sure that entire universe is covered, otherwise each beam would miss by huge margin any potential receptor
Solve long term cryosleep and start sending humans to colonize and terraform other worlds. I would volunteer for that sort of mission.
Is it possible that some life exists in gas nebula and open space rather than on planet surfaces? If this is possible than perhaps the size of said creatures would grow beyond the scope of what we were looking for and would then appear to just be giant asteroids floating around in space looking for a meal. Maybe we have seen life but didn't recognize it as anything living because it was too massive.
We have a very limited range of light wave vision. It is possible that other life forms exist outside our range of vision or have the technology to cloak themselves from our ability to see them.
"Oumuamua"... TOO strange to have been a simple asteroid. It's shape made NO sense. Gravity doesn't allow for something to form in the shape of a cigar, and orbital mechanics wouldn't allow it to have come in from outside the asteroid belt, fly by SOOOO close to earth, during which time a few smaller "asteroids" flew through our atmosphere, which didn't burn up entirely and landed in the ocean (probes). Then it somehow accelerated and flew past the sun, launching itself FAR out, back out to the asteroid belt. They've been searching the ocean where it hit, and have been finding very strange things, like what LOOKS to be a wire that we don't use, made of material that looks more fashioned than what you'd find from asteroid debris. Now we have all these strange spheres zipping around the world near military areas. Feels more like they found US and for whatever reason are doing some serious scouting.
A lot of if's and maybe's in that statement...
Dream on! 😆
@@dying2play517 it was a enourmous space dildo!!!
I think...
1) they know we are here but we are too violent and "primitive" to worry about. So could have a "radio jammer" surrounding our solar system to stop us hearing them.
2) Interstellar space travel is just impossible so we wouldn't know anyone was there anyway.
3) Other intelligent life forms don't have the same questions as we do about the universe so aren't looking into space travel at all and are worrying about other things on their own planets.
Concerning your #3 point:
I've always wondered why more people don't seem to grasp the concept that intelligent beings who have evolved under entirely different circumstances than modern humans simply may not be motivated to explore beyond their home. Seeking answers to unknowns and a pervasive need to know what's around the next corner could be concepts completely unique to humans who've evolved on Earth. An alien civilization may be made up of sentient beings with far, far different instincts and curiosities. They could even exist with no concept of curiosity playing any role in their survival. Ever. Curiosity itself may be a very uniquely human thing. Any alien civilization that evolved 100% independently of life on Earth probably have priorities and instincts and ways of doing things that we couldn't imagine if we tried!
The first point, I dont think they are hippies so in their eyes it doesent matter.
your second point is the reason...so many people just cant understand or learn basic physics
