Excuse me, but, given that I tend to be an observant person, I think being born into such a hostile world, and being granted mortal life involving inevitable/inescapable suffering is far worse than either of those two possibilities.
Those two are not so bad, especially the first one (we are alone). What is terrifying is that we live in a very violent and hostile universe. Black holes, asteroids, neutron blasts, and here on earth disease, human stupidity and ignorance, greed. Yet it is what it is, so we either thrive despite all of that, or we die as a species.
Humans have been broadcasting radio waves for about 100 years, so our furthest signal is about 100 light years away. If the universe (~93 billion light years across) were the size of the pacific ocean (~11,000 km across), then our furthest radio waves have reached about 12 millimeters. But we can't even observe our nearest star in any detail and that's only 4 light years away (~half a millimeter). On this scale the Milky Way galaxy is about 12 meters across and Pluto would be about 75,000th of a millimeter away. So it'll be about another 90k years before our signal reaches the edge of just our own galaxy, and then double that to receive a response. A civilization could have started much sooner than ours and have been broadcasting a lot sooner as well, but depending on how far away it is, it could take 1000's of years to respond, so we might as well be alone. A conversation with Mars could take up to 20 minutes for a response, so I couldn't imagine how excruciating it would be to try to have a conversation with someone 10k light years away lol.
Now that I think about it if you observe any random 12mm in the Pacific ocean you probably won't come across life. Probably not even if you observe 12 meters of the ocean. You would conclude there is no life there.
i am 20 and i just wish that atleast before i die,i get to see a real proof of intelligent aliens.i just dont wanna die knowing that we dont share this incredible universe with any other intelligent being.
We’re not alone - we share the universe with a few billion other people, which is nice. We get to talk about it with each other, which I find comforting. I think when people look for aliens, they’re really looking for the knowledge that that discovery would entail - they’re looking for answers about so many things. I think people are really looking for God, but, since humans are averse to being told what to do, they instead try to find something else god-like, preferably an alien species that will give us answers and then let us blow them up and retain our independence and feeling of superiority. Thus: aliens. That’s my theory, anyway. Personally, I believe in God and think that He wants us to colonize the universe... eventually... once we realize that we can’t really sort ourselves out without him. I think humans were not designed to be alone or go it alone like we keep doing. We’re meant to be connected to the divine. Trouble is, religion is a huge mess.
@@KatyaKean humans have always been wanderers, it's in our genes. The will to learn and grow. You are kinda right stating that we look for aliens so that we can find answers to unresolved mysteries but God plays no role in it, God is just an imaginary being that never existed. There can be a positive/negative energies which maintains balance between good/bad but there God doesn't exist.

We obviously don't even know if the math actually supports his claims of probability. Furthermore, although he's obviously smart, I believe he's way in over his head if he actually thinks it's this simple. I get the feeling it's likely not, this simple.
In terms of a technologically superior species or race visiting our planet, they may not even be conscious, or present. In many cases what we witness in terms of UFOs may merely be probes or drones, designed to investigate, survey, observe, and/or ferry goods, and nothing more. This is something that we might do down the road as we develop, if we encounter other races. It would be very dangerous to actually physically encounter another biological non-human race. They may carry diseases we have no immunity to, or there may be such a dramatic language barrier that we have no means by which to translate. There is no Rosetta stone for non-terrans. Perhaps they possess superior technology with computers capable of translating our language, but would they even be interested? It's very possible that they are subject to the same industry-standard fatigue that comes from digesting person-to-person interactions which forces MANY social individuals to become introverted. How much more introverted toward less-developed civilizations would they be? Just because they stop by and wave (tic-tac probes) as they refuel (just beneath the surface of the ocean, Nimitz encounter, recently released Navy reports and footage) doesn't mean they're remotely interested in actually communicating with us. You might wave at a coworker or friend as they drive by in their car, but they wouldn't stop to chat. They're on a deadline or some other arbitrary time limitation. Just because you can travel insanely fast doesn't mean you have no deadline to meet. On the other hand they could exist in a higher dimension, even the 4th spatial dimension and while they perceive us, in our 3 dimensions, as we would perceive a cartoon on a tv screen, we may have no method by which to perceive them in their higher dimension. A 2-dimensional organism would never be able to fathom 3 dimensions without some sort of interface medium. We have no medium for higher dimensions yet.
Tyson also stated if there are only so many elements/atoms in the universe then the universe continues to grow taking these atoms etc and continually putting them together in infinite ways then at some point the universe has to reproduce the same thing. It has to repeat there for some where out there there is a replication of our selves. almost like we have a twin of our selves and identical. Its a terrible way of explaining his theory by me but it makes total sense. Secondly if time travel is possible in a million years then what we are seeing may well be us from the future. Why not?
@@naturalLin No not really. We know for a fact that life on a planet is possible as we all are the living proof of that, but we have yet to find our first living and real god. So indeed it takes faith to believe god exists, but we know for sure that life exists. You statement is therefore false.
Yes believe in God takes faith because we don't see him, hence faith. We have not found any life forms yet in our universe. We can do math to solve the probabilities of life in our universe. And as of now, with how good the odds are. We have yet to observe any. So we are still hoping that one day there might be a life form simple or complex.
Actually, you inadvertently said something which actually points to the truth. We never found any lifeforms in the universe? What about all the life here on earth? We are in the universe right? Except we can not actually confirm the existence of even the lifeforms here on earth. We can not know the thing itself. We must take it on faith that what our senses tell us correlates with actually existing external reality. Our perceptions are pure abstraction. Light describes things to the eye, which sends signals to the brain, which processes signals and describes images to the mind. All our senses work similarly, the nervous system sending signals, the brain processing signals and creating impressions in the mind. That is pure abstraction. The mind itself seems to be a construction of pure abstraction as well. The only thing which has any persistence, the only thing which is the thing itself rather than abstraction, the only thing we can experience and know directly, is awareness. Even our notion of "self" is an abstraction. There is only one thing we can be certain of, only one thing which is not abstraction. Some would call it God. After all, in one's own life, which is all one knows, awareness is the all seeing eye... Belief in awareness does not require faith, indeed it is the only thing which does not require faith. It is the only truly self evident thing. Awareness is... All else is debatable. So in a sense it takes more faith to believe in anything other than God, since God is the only thing which requires no faith at all. I don't believe in God though, because I don't even exist. God doesn't believe in me either, rather merely aware of the abstraction which I believe is me.

"Two possibilities exist: either we are alone in the Universe or we are not. Both are equally terrifying. -Arthur C. Clarke. A lot of people think humanity is a form of virus. What if aliens have isolated us to this system of the galaxy? Maybe we are just too far away/isolated to see or interact with other species.
I believe we were meant to have our resources exploited, and thus a population decrease is inevitable. Ebs and flows. Humans have an innate ability to adapt and create. I don't believe human beings will ever need to leave the planet, for they will course correct when conditions become extreme
If we are alone, that is both gratifying but also that would mean that we have an extremely lonesome existence. The universe is far too vast for human beings to be the only complex life form in my opinion. I also think being alone is a bit frightening and just boring generally.
more like we are either unnecessary or "unworthy" to be contacted with alien species for our resources and the fact that we are self-destructive and aggressive life form who kills its own race specimen for no reason, of course we might as well just be too far from the other nearest intelligent life civilization... and as a bonus our space research material is so feeble its kind a joke compared to the size of universe, or even our own galaxy...

Of course not ! BUT the opposite happens ! many animals actually have shown that they attracting by human beings ( Don't lough , it's true ). We also talking about intelligent beings that most likely look like us and not like animals for many reasons . I also can not believe that they haven't a natural way to reproduce because this is the only way for perpetuation and evolving .
Yes additionally we are a galactic park reserve, just like our earthly nature reserves. It has been shown that if we stay out of the parks, they are the richest in nature, where constant park visitors leave barren wasteland. Its not a choice for passerby's to pass us by, its the law. They will learn from us from afar, but leave us to our animal kingdom.

Oh, we have not limited knowledge. We have the bank of info from ... man-made scifi entertainment fiction. Most ppl who think there are aliens derive from the man-made entertainment ... but not from actual conversations with space aliens. Where are the artifacts? Where are the cadavers of space aliens preserved for all to see? Nowhere but inside the bag of ideas from man's fiction. Most TV shows, flicks of space life, present the same old ideas from ... scifi entertainment. It is sad to think that we are full of fiction make-believe knowledge while thin on facts, confirmable knowldge, objective science peer-reviewed.

Imagine if we are the only life forms in the Universe and life on Earth is ended by war, disease, etc. In that moment it means all life in the Universe would be gone, no life to live, just rocks and dust drifting throughout.
He said it better himself, that planet on proxima centari went to dust by its own sun. It seems Man got really, like REALLY lucky to exist at all. There's just so many and big forces that can end our streak of luck.
We aren't even the only life forms on this planet, notice he was talking about intelligent life like humanity, if we went extinct because of a disease animals immune to the disease would continue to exist, same with the thought that there could be lots of life in the universe but at a less intelligent stage like as bacteria or non intelligent multi-cellular life forms.
I never hear scientists explain how time might be a crucial factor. Considering we've only been around for a short time, isn't it possible other intelligent life could have existed during before multi-cell species on Earth existed? Or maybe after we're gone? I'm not sure if these theories and their equations take time into account.
@@fanatic632 Universe isn't old yet. Maybe for humans yes, but It's actually only the beginning of the universe. A lot of stars and planets will be formed in the future
I reject the whole "goldilocks zone" hypothesis. It's assuming all aliens have to be like us. If we ever find life on other planets it won't be immediately recognized as such because it's so different from anything on earth
its based off of the facets of life being carbon based. the likely hood of it being DNA based and the abundance of hydrogen and oxygen in the universe and the necessity of liquid water given the previous mentioned facets to combine and make life. of course in the entirety of universe there will a possibility for life outside of these standards but you can assume the majority of life or this version of life has the highest probability of existing. rejecting the idea of the "Goldilocks Zone" is to reject observable and understood facts of the universe. if there is more to your rejection to support why, id be very interested in your reasoning if they are factual or supported by anything other your given reasoning
What "observerable facts" are there for alien life? It's based entirely on an assumption that all life is carbon based. Is silicone based life impossible? There are bacterial organisms living inside hot lava and tardigrades can survive with very litte oxygen. If they can survive that then they can survive on a planet closer to a star then Earth is to the Sun even if they are carbon based
True, Tardigrades, for instance, have been found to survive any extreme we throw at it. There could be alien life somehow birthed on a planet right up close to the star.

I like how he says a trillion may be a small number. This helps me understand that aliens, despite the trillions of planets, or galaxies, or universes, are still too few and far between. With more time, I think the ones evolved in the "summer months" will be contacting us before we contact them.
@@aquaflow1264 Are you saying that they are so far away from us, they could not travel here (just like we could not travel there) because they could not live after so much time in travel?
Being contacted isn't always something to wish for. Logic would dictate that, to ensure the survival of your species, you would naturally exterminate all present or perceived threats to that survival.
Many alien civilizations have probaby arisen and disappeared before we even existed and will after our existence ends. The Universe exists well beyond Earth's lifetime.
The Yoyozo. Yes , if the dinosaurs had not been wiped out , land mammals would not have flourished and intelligent humans would not have developed ........there was a lot of lucky events that lead to us being here.

Things like ants and small creatures always seem able to survive catastrophe .

Extremely interesting and eye opening video, but I fail to believe there's no other intelligent life in this vast universe of ours with its trillions of galaxies. We probably haven't heard from them yet because they're thousands if not millions of light years away. Intelligent life can come about out there in different ways to how it has evolved on Earth- especially if its non- carbon based.
There's a load of unfounded assumptions in even what you've written there. For one, why would we think any such intelligent life would want to communicate with us? Because we do? Almost everything about this topic is still unknowable and unknown.
On nights (like this) when I lie awake in bed unable to sleep, I often come back to this talk. Stephen's perspective is not new, but his own belief in it - that we're the lucky one and that we have so much to be grateful for - shines through. A wise man once said "a true thing, poorly expressed, is a lie". I don't know if the perspective here is the truth, but I feel there's probably no purer expression of it. Thank you. We've got a lot of work to do.
Funny, I found his talk to be a completely unscientific series of beliefs and prejudices based on assumptions we don't have nearly enough data to assume. Maybe you should just go back to sleep.

It demonstrates how only using your own living conditions as prerequisites for other intelligent lifeforms in the universe is very narrow minded indeed. There might very well be life out there that developed intelligence and technology/abilities through means we might not be able to conceive through extrapolating from ourselves, seeing as an ant cant extrapolate how we live from their own conditions and they are also a living species on this planet with arguably a complex social structure. We have to understand that life is more resilient than we think (extremophiles) and that there are levels of life in the cosmos perhaps that we have not yet discovered or been able to study properly (life in other dimensons).
@@awegahn Thank you for explaining it better than I ever could Andreas! 😛 I actually missed part of the quote that said "Ants end their search for humans" or something along those lines. We don't respond to their pheromones as aliens might not respond to our radio waves or whatever means of communication we use. When we say "We're yet to discover alien life elsewhere in the universe" what we're really saying is 'We're yet to discover anything that resembles us on earth out there'. There could be life all around us, we just don't recognise it as life. Hypothetically if life evolved on Jupiter it would be completely different to life on earth. Life may even evolve elsewhere that's not even carbon based. Who knows? It wasn't that long ago we didnt think life could survive in the deepest depths of the ocean, or under the ice of Antarctic etc but we keep finding it in the most supposedly inhospitable places.
Even if there was a spacefaring civilization the way I like to imagine or describe the problem of contact with an alien species is to imagine every planet in the galaxy being a grain of sand on a beach, and one of those grains of sand is blue and that's Earth, and then you take a few wooden planks each one represents a spacefaring civilization, you then drop those wooden planks on to the beach at random, now each wooden plank is going to be touching dozens if not hundreds of grains of sand, which represents touching hundreds of planets with their space travel, but the chances of those planks touching that one blue Speck of sand is still incredibly small.
It's not just space, but also time. We could go extinct at any time. So you could have approx. 100 grains of sand turn blue at random times, but they're only blue for 10 minutes. The odds of making contact are not just whether the stick touches two blue grains, but also whether a snail crawling along the stick encounters two grains that are blue at the exact moment he passes. (I don't know why there's a snail on a sandy beach.)
Good analogy. Wouldn't you say though, that as the blue spec we could still look out and see the wood if we tried hard enough? I mean we have a much better chance at see the wood then it does of see us

It's that constant improvement that is dangerous. 100 years ago, the idea of humanity wiping itself out was science fiction. 50 years ago, it was a very realistic scenario and we created the doomsday clock. Making a mistake in 1870 couldn't destroy us. Making a mistake in 2100 could destroy all life on Earth easily.
How is it valid? You may have evolved past the point of needing technology. An evolved being able to use zero point energy as nourishment and able to manipulate it for locomotion no need for aerobic metabolism (don’t need to breathe) and evolved past the point of needing heat to enact enzymes for cell growth or repair. Technology then becomes arbitrary for all the uses in survival as we use today. So not in all cases is it a valid point, push your thoughts to the extreme ends of imagination as all maybe possible.

The first question to be asked, according to my twisted way of reasoning, is, "What is your definition of the term 'Alien'"? The second is: "If an alien were standing behind you in a supermarket check-out queue, are you so sure that you would recognize him/her/it as such"? The only way you would (or perhaps wouldn't) freakout is if the alien looked exactly like your preconceived idea of what an alien should/would look like. When I was a young, ten years old boy in 1950's Ohio, the subject of aliens came up while on an overnight, cat-fishing trip with my older brother and our grandfather. We were all gazing at the stars and talking about aliens (aliens were a big thing in low budget, black and white, Sci-Fi movies then) while waiting for the fish to bite. During our conversation, I happened to say, quite honestly, "I wish that I could meet someone from Outer Space". With that, my grandfather stuck out his hand and said, "Hello there, Earthling, nice to meet you". "Aw, common, grandpa, you're not from Outer Space, you came from right here on Earth", I complained. He said, "Pick out a star up there" and he waved his arm in a wide arch through the star-filled night sky. "Now, imagine," he said "if another group was on one of the planets orbiting around that star. and that they were looking up into their night sky looking back at us... follow?" "Then, where would we be?" "In outer space", I cried. That means that we are aliens... we are from outer space!" At that moment, my entire perspective of relationships of all sorts changed. I realized that the answer to any question depended, entirely, on own's own perspective. A lioness killing a lamb might seem to us like a bad thing; however, for the two hungry lion cubs waiting at home for the mother to bring dinner, it's very much a good thing. So, "Where are all the Aliens? You're looking at them." Thank you for reminding me of that magical moment so long ago.
How do you not get very depressed and fearful for our planets future? That we will not be able to overcome the current barrier and will soon extinguish ourselves and our planet for a long time to come 😓
@ In my view, and I think you honestly mean to say your real concern is not the planet but the current life forms. I do feel concerned on one level, I really do. There are several thoughts I like that link to this idea. 1.I love one quote from Sir Martin Reese, “We are the outcome of nearly four billion years of Darwinian selection but many tend to think that humans are still somehow the culmination of that. Our Sun however is less than halway through its’ lifespan, it will not be human eyes that watch our Sun’s demise five billion years from now, any creatures that then do exist, will be as different from us as we are from Bacteria. 2. Darwin noted that nature draws no hard lines or edges. We are just snap shots of chaos in motion. 3. Thinking of evolution, we are not independent of our biology. Evolution favors strategies which are not assumed to be understood by the creatures that act them out. 4. You ever see how a dog is held above water and he can’t help but perform swimming actions? A good test for our inability to act independently of our evolutionary package, try to not think for one minute. It seems like we are like the dog, we can’t not think. Another is view the “Cafe Wall Illusion” and try to see the lines straight. Even when you know they are straight, we can’t see it straight. I really feel like we have freewill but when I ponder how much of our bodies run on autopilot without my say so. I am not sure I can justify it. There is a lot of absurdity in everything. You may feel what Isaid if absurd but really do try to think of it. I’d be honestly curious in your opinion.

The problem with the argument against other intelligent life is that it is based on the limited perception of Humans, which in turn is based on our limited existence on Earth and the theories/formula's proposed to explain what we have encountered since. No doubt, other life may exist on a plane that we have not even come close to conceiving of yet. We think we're 'intelligent' as a species by our own standards, but may be considered inanimate by a species who has existed for millennia longer. A cave man could never have conceived of Virtual Reality, UA-cam, cell phones or the like and if presented with it may even think it was another way of existing altogether - which maybe it is.
You are right. Sumerian clay tablets describe the Annunaki aliens that created us. The tablets indicate the Annunaki came to earth 450,000 years ago in flying rocket ships like Elon Musk is developing today. Just consider that Scholars say our knowledge is growing exponentially. The volume of human knowledge doubling rate used to be 25 years in 1945 but is currently doubling every 12 hours. Just think how advanced the Annunaki should be with a 450,000 plus years head start on humans measly 4 thousand years of development. Their knowledge, if they have not met some extinction disaster, may be doubling every 1/1000 th of a second. Just think, scientist now think they can prove the existence of a fifth dimension by using recently detected gravitational waves. The Annunaki should be so far advanced they may know how to move between the different 12 dimensions, and they may not exist in a form we can recognize.
I'd say that's all based on an assumption that Human's have a limited perception of our limited existence. The scientific method is what we use to divorce ourselves from those limitations and biases. We've looked. That's the whole crux of the paradox. We AREN'T limited, we are very capable of making the required observations. And we did. And that's when we realized there's a problem because there isn't anyone else out there despite our intuitions making us feel as if there must be.
I don’t think that in the entire universe the conditions required for life is exactly the same as here. I think there will be all sorts of outcomes on different planets that we would never understand.
We're in no position right now to say that we are alone. We're just beginning to understand how the universe works. We've barely scratched the surface. I disagree completely with him. Though I believe intelligent life is probably very rare, maybe only a few examples per galaxy. But it's there! It's also the type of thing that could be another 100 years before we conclusively know..
Nah, we just probably have no clue what it looks like. The more likely theory nowadays is that most "alien" life would actually be mechanical or artificial intelligence in nature, as the ultimate goal of any species would be to seemingly live forever or create non-biological clones of themselves in order to lead out their likely very long lives. Who knows if we've already interacted with alien life and just didn't know it was due to our own human classification for what alien life even is.
@@swahiliranger1022 Thats possible youre right. It is thought that if we were to encounter alien life - it could well be machine/ clones/ AI etc. possibly even self replicating. Easier to send something artificial to go and do the inspections of the galaxy!
yep... but the way he summed it was pretty satisfying... because i had a thought about this a lil while before(like months) ...nd i had the same thought...just because we have not discovered it doesn't mean it doesn't exist... I for a Matter of fact thought that it would be in favour if we considered their existence than not....better to keep looking than to not... nd yep the later part...the point is they are alien species we have NO clue how they can be... they can be charges ..or microorganisms...or just beams of light.... something which doesn't have a physical form...it could be anything...(i dnt have much knowledge about the typical physics term .. I am a biology student)... I hope my points are understandable...and really...we haven't even discovered the universe in sight...let alone the universe we are ought to even see...and still very far from knowing about them... and also i read people in the comments saying he is a fool to think tht we are superior... IMO...wht can't we that... why do we often perceive aliens as something stronger than us or hostile...or as a matter of fact something with a physical body .... It could be anything and we should keep our understandings about them in the same status...
Why is he assuming that hearth is in the very tail of the distribution of planets which can host life? The problem is that we don't know that distribution and we don't know the probability for each of those barriers. How can we state that a barrier has a 1 in 1000 probability if we don't know the whole sample. It's like taking a glass of sea water and saying that in the ocean there are no fishes.
he said purely for the purposes of illustration, he wasn't seriously estimating that is the true possibility of a barrier being passed he was simply stating that, given that the possibility of a barrier being passed is almost certainly higher than 1/1000, the chances of there being alien life out there is, apparently, extremely slim, perhaps enough warrant that we are the only intelligent life in the universe
the problem here is that we suppose the barriers to be around our understanding of life. There is a possibility to that in system that deemed harsh and inhospitable for us, it is actually hospitable for such sentient species or it could accommodate new form of life that we never know or cant even begin to comprehend at all. However, his arguments (the Speaker Stephen) are also solid, assuming all sentient species would need same sophistication as us human.
@Jakeed: ok, but then for illustration purposes this is a very strong assumption which cannot be verified by any experiment or available data. So we can discuss theoretically, assume what we might think and come up with any conclusion @Nivodeus: I agree with the first part of your comment but I don't on the solidity of the assumption as it is based on a data which are very very limited observations of our universe. All the stars, planets and galaxies that can be seen today make up just 4 % of the universe. The other 96% is made of stuff astronomers can't see, detect or even comprehend and from the 4 % we even don't even know all the possible conditions under which the all the planets are. So, poor sample->poor assumption->poor conclusion
He clearly stated that he was just using 1 in 1000 for illustration purposes and he has no idea whether that's a good estimate. He didn't claim there's any support for that number.
Beautiful message in the end. With the amount of fortunate events that have occurred in order for intelligent life to exist, it is a real shame that life is not intelligent enough to take care of their special oasis in the middle of an almost infinitely and apparently empty desert.
And that's the observable universe, and looking and searching this very moment. Imagine if you throw TIME in the equation. We are looking RIGHT NOW, but the universe is 13500 million years old, civilizations may have already been and gone, or developing, or whatever. Mind blowing
The One Who Knocks This was said by Neil Degrass Tyson. It gives you a proper scale of how much space we've been able to investigate so far. It means almost none. Therefore thinking that we are alone in the universe is plain silly.
look at that guys ears...he is an alien himself. i think there is life everywhere...but not all organisms take mushrooms and other hallucinogenic plants...which uplifted a couple of individuals and the rest copied the skills....it could be that some ape in our history ate hallucinogenic plants and he was so high that he made fire.
I’ve always wondered, what if we’re first? Everyone talks about “oh the universe is so large there HAS to be others” well maybe, but someone has to be first and what if that’s us?
I think the reason people say it's not us is because there are star systems older than ours by billions of years... I mean it's still possible but I'm just explaining the reasoning.
It's more likely that we are in an early access version Simulation without any alien race implemented. Stupid Life Devs, always trying to make an easy buck with those cheap and buggy simulation games.
Another possibility, we are the first. Someone has to be. Yes, the universe is 14 billion years old, but the universe, where stars and planets still exist, will continue for another 200 billion years or more. So understanding that time line, the universe is still in its infancy. Thus we are part of that infancy, and we in fact could be the first intelligent life in the universe.
@@misterdog8346 Nah, Just like evolution here on the earth, evolution of the universe will weed us out as a defect, and the universe will become much better after we are gone.

What a great talk ....I could listen to the speaker for hours. There is a part of me that really wants to believe that there is "intelligent" life on another planet, but every point made in this talk makes that unlikely. Plus, I'm not sure we are even "intelligent" life, given the current state of things on this fragile Earth.
Glad you liked his talk. He is eloquent. However, he doesn't know any more about the subject than either of us do. And I don't claim to know the answer either, but the sheer numbers of stars planets and galaxies make him most likely wrong. Very wrong. Remember Arthur C Clarke's 1st law: "When a distinguished but elderly scientist states that something is possible, he is almost certainly right. When he states that something is impossible, he is very probably wrong.”
@@iamacepaul Yes, the fact that there is an uncountable number of stars and a limitless universe would seem to preclude the possibility that we are alone in this vast universe. The quote is quite correct. And I am certainly not is possession of the answers, that is for certain. Thanks for the comment.....
Chris Midd why would you think so ? What if they’re actively looking for other civilizations that are remotely intelligent or show intelligent behavior. Maybe they’re as excited as much as we are about finding out different types of intelligent civilizations that may look slightly similar to us.
@@hidden658 As how humanity is right now, i can understand, that aliens want nothing to do with us. In fact, if they where older than us as species, why should they pay any attention to humanity at all? We have nothing to offer. We can only take and our so called legacy is nothing, compared to civilizations of more intelligent and advanced species.

It's really surprising what we are talking about and what we're expecting. There are some questions without an answer respectively without the right priority. 1. Why should alien civilizations be interested in contacting us? Are we interesting enough for a conversation or small contact? Are we peaceful enough? Are we united? Who should be contacted? Which Goverment? Who's neutral enough and would not try to use the opportunity for an egoistical purpose? 2. Would an alien civilization need to contact us? What's the benefit of contacting us? Are there more disadvantages or advantages for the aliens? Can they trust us? Would we trust us? They know everything about us. Why? Almost 100 years of TV and Radio. They just needed something like a satellite and few small drones and not more. These are things we could do with our primitiv technical standards of our time. If alien should be able to come near to earth they should have a distinctively higher technical level. Our governments are liars, we are liars. The most people are full of anxiety, hate and egoistical wishes. The aliens would be idiots if they would believe any of the lies of the governments. Maybe one day in the future they will contact us, however, this day might be too far away for us or the next two generations. We want a contact, we should stop bombing other nations on behalf of fighting against terror and enemies which we created and controll by ourselves. We should focus our time and energy on our planet and our neighbor planets. Rescuing earth and colonialising Mars and Moon without a military option would be the next step.
@Alberto A Lopez Trump has very egoistical intentions and in case of harassment he will be very cautious. There are more than one voice recording wher he is proudly speaking how to harass a young beautiful woman. Anyway, I didn't want to start a political discussion about him. Thanks for the explanation.
Kein_indianer, You might also think of it the other way around. That is, why would we want to contact distant civilizations? The distances involved are so vast that anything we could get from a distant intelligence would not be worth the trouble of getting it. People seem desperate to know that we are alone, or are desperate to know that we are not. But just what do we do with the information if we find what we could be sure was a definitive answer? If those who are watching for such things were able to announce tomorrow morning that they had detected, and were able to prove that they had detected, what for dead certain is intelligent life in deep space, what difference would that make? I mean, what concrete practical difference? Does that make life better? Or worse? You can say that it will be satisfying to have the answer, but that seems to me mere curiosity. I can't get excited about satisfying that.
your abosluteley wrong there, just the mere fact of recieving *any* kind of communication from distant intelligent life would change the mindsets of millions if not billions of people which would filter down to the way people individually or collectively think,do,invest in or even ones fundamental core principles might change (i know mine would)It would absoluteley change our way of life as we know it. of course that is if the guv-ment decided to even release that fact to us mere peons, on the pretence of *protecting* us.
Alberto A Lopez Trump's space army is: 1. His big military plan. 2. Needed to stay on top of China. 3. Senseless, and earth-centric. 4. Paedophelia isn't cuz of aliens at all. 5. Reptilians do not exist, the sun would fry them whilst warming. At best/worst they are demons, albeit far from real.
According to that clock of 24 hours, we've only been looking for 0.000001 seconds... Still, its plausible its just us and yet we still can't work out how to put on a quilt cover alone without getting angry.
That's only if you assume the age of the universe. Remember it fluctuates all the time. Anytime modern science cant explain stuff they just add more years lol. If we are honest nobody knows how old we are.
@@kenbrunet6120 Indeed. Still, imho it's a bit naive to BELIEVE that we are alone when we've sampled like 0,000000000000000000000000000000000000001% of the galaxy. I probably put too few zeros in there, but you get the point.
@@georgexanthopoulos3003 But the point is if life happened elsewhere then looking at 0.00000000000001% of the galaxy would in fact bring up evidence of aliens. We haven’t actually done that though, we’ve looked at other galaxies and when scientists expected to see some with dimmed light, from them harvesting energy from stars, they saw nothing that wasn’t completely natural. You only have to look at 0.00000000000001% of the ocean to see life, just as advanced aliens would have already colonised the galaxy, if they could exist elsewhere.
@@tomben6180 Not it wouldn't. You find life in 0,00000000etc. of the ocean because life is abundant on Earth. Nobody said alien life is abundant, only that it's not as unique as some may think.
I imagine us as ants on the shoreline of a galaxy even more vast than the oceans. What possible life exists beyond the horizon, too far for us to even comprehend.
I had a similar thought to this. We tend to assume that if aliens exist, they would be relatively similar size to us. They could be the size of mountains and live so far away we'll never know.
@@kenbrunet6120 i was recently thinking about this again and i started to wonder. For all we know, our planet could be a subatomic particle with our galexy being an atom of a higher plane of reality. How could we know?
@@YukihyoShiraki Yeah very intriguing idea. Oddly enough, that concept was revealed to me the first time i watched Men in Black. At the end when they zoom out of our galaxy and we're contained within a marble among other marbles in a game played by other beings.

Let's hope that our AI technology can be used for that purpose and all the potential hazards of AI going off on it's own being avoided!
Forget about the IF we are alone question. Lets just say that we ARE alone in the universe. The vast universe ALL empty, just US here. Wouldnt that make us , the human species, FAR beyond valuable?! How unique we are. How rare and special we are. It doesnt take much to notice it. Just look at the creation of babies. The growth and learning patterns of children. The intelligence and ingenuity of man. How well and adaptable our bodies are designed. I think most people are looking at our existence from the opposite end. NOT how small and insignificant we are, but on the contrary , how unique, special , and awesome we all are.
That's basically the theological/Biblical view, where the Universe was not meant to be a "zoo", teaming with life just waiting to be discovered by us; but rather more of an "art gallery", with the exception of one place (Earth) serving as the location where the "artist" decided to physically represent Himself (mankind/life) even to the point of eventually injecting his very self (Jesus) into this same creation. Bible says the whole creation fell in Adam by his sin, which would be profoundly unjust to any aliens "out there" who had nothing to do with mankind's original transgression, yet made to suffer the same effects.
The more probable scenario, and I believe this to be a more sensible theory, is that there are thousands, maybe millions of civilizations out there. But the universe is so big, that few would be able to reach others while their civilization lasts. Like Tyson says, to conclude we’re alone, is like examining a glass of water taken from the ocean and conclude there’s no fish in the sea.
If you want a much more comprehensive answer than this I would suggest you watch Isaac Arthur's Great Filter series of videos here on UA-cam. He goes into great detail and has a much more developed answer to many of these questions.
Sam Fanthorpe Not just those specific videos, his entire channel would be incredibly interesting to anybody remotely intrigued by the idea of this TED talk.
I love Isaac Arthur's channel but regarding UFOs he has talk about UFOs but obviously has not spent any time studying the subject matter. I have spent a solid year studying the subject as an engineer and I am convinced there is something behind all the smoke. Anyone who actually studies the phenomenon comes to the same conclusion, 5-10 percent of reported sightings, and I mean pilots, radar operators, police officers, or large groups of witnesses some times even entire towns are not dismissible.
At 11:44 he states: “I think we’re alone.” And in our solar system we are. We have to be an experiment of an advance civilization to see how we turn out. The “creators” will either advance us or let us kill ourselves as not worthy of advancing. Let’s prove them wrong!
They would be looking for us in many formats to low in technology or to high to detect us so in the same logic their conclusion would be no life in the universe
@@davidarriaga6643 If they discover us, there will be evaluation of our technology. If we are lesser than them expect invasion and colonization from them. If they are lesser in technology, they will avoid us. All this is one big IF
An Alien from outer space well if they are able to detect us and decipher whether our technology is more advanced than theirs or not you’d think the answer is pretty obvious. But I don’t think this would necessarily mean an invasion. Would we invade if it was us with the superior technology? I’m not sure, especially if it was the inky encounter we’d ever had, I don’t think we’d want to destroy it or them.
@@marcushancock1997 Just simply look at our history, carbon based life require constant burn of energy or death from depleting energy if not replenished. Like wise a carbon based life beings will find out our solar system is full of gas giants and earth 85% water which could be harvested for hydrogen energy. Other matters needs to be considered like germs, heat, gravity and so on. Early settlers always suffered from those until future generation adapted.
I concur with the speaker "We are alone" and are comforted by this, because the opposite would be if we ever did detect the existence of other intelligent life forms our species would destroy its self over the the fact we were not alone.
Every civilization beyond 100 light years distance from our planet will not notice our presence, because our signals have not reached them yet. And our Milky Way galaxy is up to 200,000 light years in diameter.
The Milky Way is 100,000 light years across. As this guy said, other civilizations could have developed as early as 6 billion years ago - enough time to send a signal across 60,000 Milky Ways.
@@cy8685 What sort of titanic planet sized transmitter did you have in mind here. And given how even that monster compared to the size of the galaxy would represent a grain of sand on the earth, what are the odds that it was ever pointed at our general direction?
TheMagdaDar - What kind of argument are you presenting that doesn't already support the fact that we have detected no intelligent life anywhere in the Universe?
"“The wise remain hidden. Your world is known to a few, but not to many. You do not want to broadcast into the universe who you are and what you have. In the future, your radio technology will have to be completely changed. You cannot be broadcasting out into space. That only invites inquiry, interest and suspicion. Right now you think that there is no one else out there, that the universe is vast and empty and that there might be some distant planet somewhere that could receive your transmissions. If you understood the situation, you would see how dangerous and unwarranted this is.” Marshall Vian Summers. “Life in the Universe.” newmessage.org/life-universe
he is underestimating how universe works and life, we are talking about looking life on other stars when we have not even been able to confirm that in our own star apart from earth. Life could exist in different conditions. it is definitely there and we are not so special.
Before we saw the first planet around another star, there were people that were ABSOLUTELY SURE, CERTAIN, POSITIVE that there were NO OTHER PLANETS in the UNIVERSE!!!!! THE WHOLE UNIVERSE!!!!!!!!! THEN we find out, not only are there MANY planets, but that, ALMOST ALL STARS *HAVE* PLANETS!
The difference dead objects like planets and living beings is that dead object does nothing to catch your attention while a livings leave marks of their existence absolutely everywhere. That means that either there's no aliens or they are equal to us or below when it comes to technology.
We could have 10 times more technology, no one further away than ~100 light years would know we're here. Do you have any idea how hard it is to notice a planet that is only 40, 30 or even 20 light years away from us? I could be wrong, but so far we've only been able to see planets that are 4 or 5 times bigger than we are, as it is. Also, how many times have we been to Mars, and JUST 3 weeks ago they found a water lake under the polar (carbon dioxide, dry) ice there!!! www.nationalgeographic.com/science/2018/07/news-lake-found-mars-water-polar-cap-life-space/ They are saying that 2, 3 or even more of the moons of Jupiter and Saturn combined MAY have microbial life on them. Imagine, possibly FIVE places just in *this* solar system may have or had life on them.
the argument isn't about whether or not we would notice life. you're misinterpreting what he's saying. he's saying that the chances for life forming in the first place, based on the information we CURRENTLY have, seems to point to many walls that would keep interstellar life from forming at all. it would only take a single species that expanded across the galaxy for us to find some sort of evidence. yet we haven't seen even a whisper of a trace of alien's. the problem is that if there were even one interstellar species - which you would think would happen in the billions of years the universe has been around - we would have noticed them.
What *precisely* did he point to that says "seems to point to many walls that would keep interstellar life from forming at all"? And, just how many "walls" were there? I'll help you with a few. 1) The Earth has a day of the length it has. YAWN. Mars' "day" is 24 hours +37 minutes. FAIL. 2) The Moon is making the Earth have a stable 23.5 degree tilt. YAWN. Mars' tilt is slightly more at 25 degrees. FAIL! 3) We need a Moon. YAWN. Mars has 2 moons. Two teeny tiny teeny weeny moons that are literally of no consequence... Oh, wait, one of them WILL "fall from the sky" which could POSSIBLY wipe out all life on Mars, if there were any there. YAWN.... EPIC fail!!!! So, does he have any other CLEVER reasons of why we are "alone"? He CLEARLY doesn't understand, big, and I mean REALLY REALLY BIG numbers. His brain IS "teeny tiny teeny weeny" as the moons that Mars has. :-(
The problem is abiogenesis. The biologist Robert Shapiro estimated that to create a bacteria from random processes would happen once in 10 to the power of 40,000. He thought there was some unknown process that greatly reduced the odds, but maybe not. We might just be the result of the stupendous random occurrences in an infinite universe.
Of all the debates and talks i have heard and watched to date.This is the one that makes sense in the real world.We are the ones that will civilise space.If we dont destroy ourselves.
About 15 years ago I saw something in the sky. I stared at it for a couple of seconds. It moved from one place to another like nothing. I guess the speed of light. It's difficult for me to think we are the only ones here in the world.
Yep, those who have seen an object darting around like that, know it isn't something normal. Or at least we have never seen anything like it, ever. I too have seen one similar to what you describe, but I saw mine in about 1976. If I saw one today, I would chalk it up to us developing some type of anti-gravity technology, but all the way back in 1976, without sophisticated computers, come on! I hope before I die, there will be some type of concrete explanation of this.
I like the way this guy said he saw a saucer in the sky as a kid and just probably misunderstood what it was, That's the lamest argument I have ever heard from someone who is supposed to be knowledgeable. "I must have been mistaken". What else do you think it was, hotshot?

You know what is scarier than either the idea that we are alone in the universe or the idea that there is life so advanced that we arent worth their time? The idea that there is other life out there but that we are currently the most advanced, and 500,000,000 years from now we are the leaders of the universe and going about the universe treating its life and resources as we do our own here on earth.
That we are not worth their time does not make them invisible. A K3 civilization is so massively obvious that their existence even billions of lightsyears away would have been clear since the 60s. +Sudip; what is "humanity" in 500 million years anyway? Maybe we evolved so differently that we look like a Star Wars esemble, including uplifted chimps, elephants and ravens.
I just want a mass extinction or the judgement day to stop our species' progress well before we evolve into omniscient overlords. It's much better to go extinct while we are asking questions, fantasizing about the mysteries of creation, rather than knowing everything and unable to question or wonder because there's nothing left to wonder about.
There will always be something to wonder about. Even if you had all the knowledge you could obtain through science ( ≠ omniscient) you could still wonder about how the story of your favourite author might continue next week.
We are "the Ancients". The universe has existed for a long time yes, but getting past all the barriers is so hard that we are the first. In millions of years some race who made it to the level of travelling between stars will find our planet. And they will know that someone else DID exist, but long long ago. Our ruins mostly gone because of entropy and all that time
Arthur C. Clarke - 'Two possibilities exist: either we are alone in the Universe or we are not. Both are equally terrifying.'
Excuse me, but, given that I tend to be an observant person, I think being born into such a hostile world, and being granted mortal life involving inevitable/inescapable suffering is far worse than either of those two possibilities.
Those two are not so bad, especially the first one (we are alone). What is terrifying is that we live in a very violent and hostile universe. Black holes, asteroids, neutron blasts, and here on earth disease, human stupidity and ignorance, greed. Yet it is what it is, so we either thrive despite all of that, or we die as a species.
that is obvious i could have said that myself
ladies and gentlemen meet the man who is afraid of everything ...
why?
Humans have been broadcasting radio waves for about 100 years, so our furthest signal is about 100 light years away. If the universe (~93 billion light years across) were the size of the pacific ocean (~11,000 km across), then our furthest radio waves have reached about 12 millimeters. But we can't even observe our nearest star in any detail and that's only 4 light years away (~half a millimeter). On this scale the Milky Way galaxy is about 12 meters across and Pluto would be about 75,000th of a millimeter away.
So it'll be about another 90k years before our signal reaches the edge of just our own galaxy, and then double that to receive a response. A civilization could have started much sooner than ours and have been broadcasting a lot sooner as well, but depending on how far away it is, it could take 1000's of years to respond, so we might as well be alone. A conversation with Mars could take up to 20 minutes for a response, so I couldn't imagine how excruciating it would be to try to have a conversation with someone 10k light years away lol.
It doesn't have to travel to the edge. Just to the next responder.
YOU! I like you....and that is so correct.
Nice written @ Eternal Reign.
Now that I think about it if you observe any random 12mm in the Pacific ocean you probably won't come across life. Probably not even if you observe 12 meters of the ocean. You would conclude there is no life there.
You should be talking on Ted, not some pessimist disguised as a realist
i am 20 and i just wish that atleast before i die,i get to see a real proof of intelligent aliens.i just dont wanna die knowing that we dont share this incredible universe with any other intelligent being.
We’re not alone - we share the universe with a few billion other people, which is nice. We get to talk about it with each other, which I find comforting. I think when people look for aliens, they’re really looking for the knowledge that that discovery would entail - they’re looking for answers about so many things. I think people are really looking for God, but, since humans are averse to being told what to do, they instead try to find something else god-like, preferably an alien species that will give us answers and then let us blow them up and retain our independence and feeling of superiority. Thus: aliens. That’s my theory, anyway. Personally, I believe in God and think that He wants us to colonize the universe... eventually... once we realize that we can’t really sort ourselves out without him. I think humans were not designed to be alone or go it alone like we keep doing. We’re meant to be connected to the divine. Trouble is, religion is a huge mess.

In terms of a technologically superior species or race visiting our planet, they may not even be conscious, or present. In many cases what we witness in terms of UFOs may merely be probes or drones, designed to investigate, survey, observe, and/or ferry goods, and nothing more. This is something that we might do down the road as we develop, if we encounter other races. It would be very dangerous to actually physically encounter another biological non-human race. They may carry diseases we have no immunity to, or there may be such a dramatic language barrier that we have no means by which to translate. There is no Rosetta stone for non-terrans. Perhaps they possess superior technology with computers capable of translating our language, but would they even be interested? It's very possible that they are subject to the same industry-standard fatigue that comes from digesting person-to-person interactions which forces MANY social individuals to become introverted. How much more introverted toward less-developed civilizations would they be? Just because they stop by and wave (tic-tac probes) as they refuel (just beneath the surface of the ocean, Nimitz encounter, recently released Navy reports and footage) doesn't mean they're remotely interested in actually communicating with us. You might wave at a coworker or friend as they drive by in their car, but they wouldn't stop to chat. They're on a deadline or some other arbitrary time limitation. Just because you can travel insanely fast doesn't mean you have no deadline to meet.
On the other hand they could exist in a higher dimension, even the 4th spatial dimension and while they perceive us, in our 3 dimensions, as we would perceive a cartoon on a tv screen, we may have no method by which to perceive them in their higher dimension. A 2-dimensional organism would never be able to fathom 3 dimensions without some sort of interface medium. We have no medium for higher dimensions yet.

Tyson said it best. Humans take a glass of water from the ocean and say "There are no whales in the ocean!"
Nautilus1972 it takes more faith to believe there are lifeforms in our universe than to believe in God.
Tyson also stated if there are only so many elements/atoms in the universe then the universe continues to grow taking these atoms etc and continually putting them together in infinite ways then at some point the universe has to reproduce the same thing. It has to repeat there for some where out there there is a replication of our selves. almost like we have a twin of our selves and identical.
Its a terrible way of explaining his theory by me but it makes total sense. Secondly if time travel is possible in a million years then what we are seeing may well be us from the future. Why not?
@@naturalLin No not really. We know for a fact that life on a planet is possible as we all are the living proof of that, but we have yet to find our first living and real god. So indeed it takes faith to believe god exists, but we know for sure that life exists. You statement is therefore false.
Yes believe in God takes faith because we don't see him, hence faith. We have not found any life forms yet in our universe. We can do math to solve the probabilities of life in our universe. And as of now, with how good the odds are. We have yet to observe any. So we are still hoping that one day there might be a life form simple or complex.
Actually, you inadvertently said something which actually points to the truth. We never found any lifeforms in the universe? What about all the life here on earth? We are in the universe right? Except we can not actually confirm the existence of even the lifeforms here on earth. We can not know the thing itself. We must take it on faith that what our senses tell us correlates with actually existing external reality.
Our perceptions are pure abstraction. Light describes things to the eye, which sends signals to the brain, which processes signals and describes images to the mind. All our senses work similarly, the nervous system sending signals, the brain processing signals and creating impressions in the mind. That is pure abstraction. The mind itself seems to be a construction of pure abstraction as well.
The only thing which has any persistence, the only thing which is the thing itself rather than abstraction, the only thing we can experience and know directly, is awareness. Even our notion of "self" is an abstraction. There is only one thing we can be certain of, only one thing which is not abstraction. Some would call it God. After all, in one's own life, which is all one knows, awareness is the all seeing eye... Belief in awareness does not require faith, indeed it is the only thing which does not require faith. It is the only truly self evident thing. Awareness is... All else is debatable.
So in a sense it takes more faith to believe in anything other than God, since God is the only thing which requires no faith at all. I don't believe in God though, because I don't even exist. God doesn't believe in me either, rather merely aware of the abstraction which I believe is me.

I never hear scientists explain how time might be a crucial factor. Considering we've only been around for a short time, isn't it possible other intelligent life could have existed during before multi-cell species on Earth existed? Or maybe after we're gone? I'm not sure if these theories and their equations take time into account.
I agree with you. Universe is so old. Who would precisely know what happened in past.
The Drake equation does take time into account. It's a fascinating equation that has been widely accepted by the scientific community.
You are completely correct. And the Drake equation does not adequately address the vastness of the differing time windows.

@@fanatic632 Universe isn't old yet. Maybe for humans yes, but It's actually only the beginning of the universe. A lot of stars and planets will be formed in the future
I reject the whole "goldilocks zone" hypothesis. It's assuming all aliens have to be like us. If we ever find life on other planets it won't be immediately recognized as such because it's so different from anything on earth
its based off of the facets of life being carbon based. the likely hood of it being DNA based and the abundance of hydrogen and oxygen in the universe and the necessity of liquid water given the previous mentioned facets to combine and make life.
of course in the entirety of universe there will a possibility for life outside of these standards but you can assume the majority of life or this version of life has the highest probability of existing.
rejecting the idea of the "Goldilocks Zone" is to reject observable and understood facts of the universe.
if there is more to your rejection to support why, id be very interested in your reasoning if they are factual or supported by anything other your given reasoning
What "observerable facts" are there for alien life? It's based entirely on an assumption that all life is carbon based. Is silicone based life impossible? There are bacterial organisms living inside hot lava and tardigrades can survive with very litte oxygen. If they can survive that then they can survive on a planet closer to a star then Earth is to the Sun even if they are carbon based
True, Tardigrades, for instance, have been found to survive any extreme we throw at it. There could be alien life somehow birthed on a planet right up close to the star.

Being contacted isn't always something to wish for. Logic would dictate that, to ensure the survival of your species, you would naturally exterminate all present or perceived threats to that survival.
Many alien civilizations have probaby arisen and disappeared before we even existed and will after our existence ends. The Universe exists well beyond Earth's lifetime.

Intelligent life can come about out there in different ways to how it has evolved on Earth- especially if its non- carbon based.
They aren't talking, they are listening. Just like we are mostly just listening.
Yes that’s true, however unless aliens exist in our galaxy cluster they are basically as good as non existant
Doesn’t matter if there’s billions of life forms…they won’t be coming here because of the distances involved.

It demonstrates how only using your own living conditions as prerequisites for other intelligent lifeforms in the universe is very narrow minded indeed. There might very well be life out there that developed intelligence and technology/abilities through means we might not be able to conceive through extrapolating from ourselves, seeing as an ant cant extrapolate how we live from their own conditions and they are also a living species on this planet with arguably a complex social structure. We have to understand that life is more resilient than we think (extremophiles) and that there are levels of life in the cosmos perhaps that we have not yet discovered or been able to study properly (life in other dimensons).
@@awegahn Thank you for explaining it better than I ever could Andreas! 😛
I actually missed part of the quote that said "Ants end their search for humans" or something along those lines. We don't respond to their pheromones as aliens might not respond to our radio waves or whatever means of communication we use. When we say "We're yet to discover alien life elsewhere in the universe" what we're really saying is 'We're yet to discover anything that resembles us on earth out there'. There could be life all around us, we just don't recognise it as life. Hypothetically if life evolved on Jupiter it would be completely different to life on earth. Life may even evolve elsewhere that's not even carbon based. Who knows? It wasn't that long ago we didnt think life could survive in the deepest depths of the ocean, or under the ice of Antarctic etc but we keep finding it in the most supposedly inhospitable places.
Even if there was a spacefaring civilization the way I like to imagine or describe the problem of contact with an alien species is to imagine every planet in the galaxy being a grain of sand on a beach, and one of those grains of sand is blue and that's Earth, and then you take a few wooden planks each one represents a spacefaring civilization, you then drop those wooden planks on to the beach at random, now each wooden plank is going to be touching dozens if not hundreds of grains of sand, which represents touching hundreds of planets with their space travel, but the chances of those planks touching that one blue Speck of sand is still incredibly small.
It's not just space, but also time. We could go extinct at any time. So you could have approx. 100 grains of sand turn blue at random times, but they're only blue for 10 minutes. The odds of making contact are not just whether the stick touches two blue grains, but also whether a snail crawling along the stick encounters two grains that are blue at the exact moment he passes.
(I don't know why there's a snail on a sandy beach.)
Good analogy. Wouldn't you say though, that as the blue spec we could still look out and see the wood if we tried hard enough? I mean we have a much better chance at see the wood then it does of see us
Indeed, we can see way more "grains" of sand and our ability to see ever further will only increase :D
there are so many variables to the development of life its almost impossible to say whether we're alone or not. Such an interesting field of research, especially in how life began on earth

How is technology today a valid point as a barrier when technology is improving daily?
@@patrickhannon4188 You're looking at it backwards. It's that constant improvement that is dangerous. 100 years ago, the idea of humanity wiping itself out was science fiction. 50 years ago, it was a very realistic scenario and we created the doomsday clock. Making a mistake in 1870 couldn't destroy us. Making a mistake in 2100 could destroy all life on Earth easily.
How is it valid? You may have evolved past the point of needing technology. An evolved being able to use zero point energy as nourishment and able to manipulate it for locomotion no need for aerobic metabolism (don’t need to breathe) and evolved past the point of needing heat to enact enzymes for cell growth or repair. Technology then becomes arbitrary for all the uses in survival as we use today. So not in all cases is it a valid point, push your thoughts to the extreme ends of imagination as all maybe possible.
@@pepewhisker2966 Earthquakes were reported close to Iran's only nuclear reactor. They're threatening to attack Israel is US retaliates. Israel has nuclear weapons.

The first question to be asked, according to my twisted way of reasoning, is, "What is your definition of the term 'Alien'"?
The second is: "If an alien were standing behind you in a supermarket check-out queue, are you so sure that you would recognize him/her/it as such"?
The only way you would (or perhaps wouldn't) freakout is if the alien looked exactly like your preconceived idea of what an alien should/would look like.
When I was a young, ten years old boy in 1950's Ohio, the subject of aliens came up while on an overnight, cat-fishing trip with my older brother and our grandfather. We were all gazing at the stars and talking about aliens (aliens were a big thing in low budget, black and white, Sci-Fi movies then) while waiting for the fish to bite. During our conversation, I happened to say, quite honestly, "I wish that I could meet someone from Outer Space".
With that, my grandfather stuck out his hand and said, "Hello there, Earthling, nice to meet you".
"Aw, common, grandpa, you're not from Outer Space, you came from right here on Earth", I complained.
He said, "Pick out a star up there" and he waved his arm in a wide arch through the star-filled night sky.
"Now, imagine," he said "if another group was on one of the planets orbiting around that star. and that they were looking up into their night sky looking back at us... follow?" "Then, where would we be?"
"In outer space", I cried. That means that we are aliens... we are from outer space!"
At that moment, my entire perspective of relationships of all sorts changed. I realized that the answer to any question depended, entirely, on own's own perspective.
A lioness killing a lamb might seem to us like a bad thing; however, for the two hungry lion cubs waiting at home for the mother to bring dinner, it's very much a good thing.
So, "Where are all the Aliens? You're looking at them."
Thank you for reminding me of that magical moment so long ago.
Love this!!! Thanks for sharing !!
Thank you, eM.
Glad something I wrote helped someone else.
I hadn't thought of it like this, that really is awesome
Absolutely.
Grandfathers are fantastic! Wonderful story,thank you Sir!
I encourage you to read C.S. Lewis’ Space Trilogy. It will make you think about one possibility for life on other planets.
Malacandra and Perelandra can only be reached from the 1940s.
I have watched this video easily twenty times over the last few years. I love the sense of wonder.
How do you not get very depressed and fearful for our planets future? That we will not be able to overcome the current barrier and will soon extinguish ourselves and our planet for a long time to come 😓
@ In my view, and I think you honestly mean to say your real concern is not the planet but the current life forms. I do feel concerned on one level, I really do. There are several thoughts I like that link to this idea.
1.I love one quote from Sir Martin Reese, “We are the outcome of nearly four billion years of Darwinian selection but many tend to think that humans are still somehow the culmination of that. Our Sun however is less than halway through its’ lifespan, it will not be human eyes that watch our Sun’s demise five billion years from now, any creatures that then do exist, will be as different from us as we are from Bacteria.
2. Darwin noted that nature draws no hard lines or edges. We are just snap shots of chaos in motion.
3. Thinking of evolution, we are not independent of our biology. Evolution favors strategies which are not assumed to be understood by the creatures that act them out.
4. You ever see how a dog is held above water and he can’t help but perform swimming actions? A good test for our inability to act independently of our evolutionary package, try to not think for one minute. It seems like we are like the dog, we can’t not think. Another is view the “Cafe Wall Illusion” and try to see the lines straight. Even when you know they are straight, we can’t see it straight.
I really feel like we have freewill but when I ponder how much of our bodies run on autopilot without my say so. I am not sure I can justify it.
There is a lot of absurdity in everything. You may feel what Isaid if absurd but really do try to think of it. I’d be honestly curious in your opinion.
All of the aliens are in a party where humans aren't invited because we're not cool enough to be.
amazing 👏👏👏 you must to be there. not with us. believe me.
Who will want to invite the crazy ones . Always fighting among themselves. 🤣
Maybe aliens stopping to talk to us would be like us stopping to talk to an ant on the sidewalk.
That's a common view, but since our universe is "uniform" - so should be any life within (for example, carbon-based).
Scientists on Earth study ants everyday. Even kids with magnifying glasses study ants. If aliens found us I can't see why they wouldn't observe us or destroy us
@@patstaysuckafreeboss8006 , how many people do you know who stop on the sidewalk to communicate with an ant? Why? Your answer could be the same with ET and us.
@@reaality3860 I couldn't give you an exact number but I've seen dozens of people kill insects for no reason. Just because we're lightyears more intelligent than an ant doesn't mean people neverinteract with them. Instead of arguing how about you use some logic. It's not hard to agree with someone unless you're being stubborn 🤷♂️
@@reaality3860 I'm just pointing out the flaws of your ant analogy. I know what you think you're trying to say but you obviously aren't grasping the concept of what I'm trying to say. You're argument is we never interact with ants because of the wide gap in intelligence when in reality people literally have ant farms in their bedrooms observing ants and the ants have no clue the human exists. There's no way for you to prove we aren't being observed by aliens right now. Just think about it
The problem with the argument against other intelligent life is that it is based on the limited perception of Humans, which in turn is based on our limited existence on Earth and the theories/formula's proposed to explain what we have encountered since. No doubt, other life may exist on a plane that we have not even come close to conceiving of yet. We think we're 'intelligent' as a species by our own standards, but may be considered inanimate by a species who has existed for millennia longer. A cave man could never have conceived of Virtual Reality, UA-cam, cell phones or the like and if presented with it may even think it was another way of existing altogether - which maybe it is.
You are right. Sumerian clay tablets describe the Annunaki aliens that created us. The tablets indicate the Annunaki came to earth 450,000 years ago in flying rocket ships like Elon Musk is developing today. Just consider that Scholars say our knowledge is growing exponentially. The volume of human knowledge doubling rate used to be 25 years in 1945 but is currently doubling every 12 hours. Just think how advanced the Annunaki should be with a 450,000 plus years head start on humans measly 4 thousand years of development. Their knowledge, if they have not met some extinction disaster, may be doubling every 1/1000 th of a second. Just think, scientist now think they can prove the existence of a fifth dimension by using recently detected gravitational waves. The Annunaki should be so far advanced they may know how to move between the different 12 dimensions, and they may not exist in a form we can recognize.
I'd say that's all based on an assumption that Human's have a limited perception of our limited existence. The scientific method is what we use to divorce ourselves from those limitations and biases. We've looked. That's the whole crux of the paradox. We AREN'T limited, we are very capable of making the required observations. And we did. And that's when we realized there's a problem because there isn't anyone else out there despite our intuitions making us feel as if there must be.
But if he was born now he would understand them
That's kind of the way I see it. And we aren't that important either.
@@iamacepaul Humans are all that there is!
I don’t think that in the entire universe the conditions required for life is exactly the same as here. I think there will be all sorts of outcomes on different planets that we would never understand.
No, you're wrong; he is an astronomer, you are a business owner.
Shut the front door.
S P That's totally illogical. You might as well speculate that there is a planet of flying spaghetti monsters out there somewhere
We're in no position right now to say that we are alone. We're just beginning to understand how the universe works. We've barely scratched the surface. I disagree completely with him. Though I believe intelligent life is probably very rare, maybe only a few examples per galaxy. But it's there! It's also the type of thing that could be another 100 years before we conclusively know..
Nah, we just probably have no clue what it looks like. The more likely theory nowadays is that most "alien" life would actually be mechanical or artificial intelligence in nature, as the ultimate goal of any species would be to seemingly live forever or create non-biological clones of themselves in order to lead out their likely very long lives. Who knows if we've already interacted with alien life and just didn't know it was due to our own human classification for what alien life even is.
.
agreed. these "skeptics" are ridiculous.
@@swahiliranger1022 Thats possible youre right. It is thought that if we were to encounter alien life - it could well be machine/ clones/ AI etc. possibly even self replicating. Easier to send something artificial to go and do the inspections of the galaxy!
yep...
but the way he summed it was pretty satisfying... because i had a thought about this a lil while before(like months) ...nd i had the same thought...just because we have not discovered it doesn't mean it doesn't exist... I for a Matter of fact thought that it would be in favour if we considered their existence than not....better to keep looking than to not...
nd yep the later part...the point is they are alien species we have NO clue how they can be... they can be charges ..or microorganisms...or just beams of light.... something which doesn't have a physical form...it could be anything...(i dnt have much knowledge about the typical physics term .. I am a biology student)... I hope my points are understandable...and really...we haven't even discovered the universe in sight...let alone the universe we are ought to even see...and still very far from knowing about them... and also i read people in the comments saying he is a fool to think tht we are superior... IMO...wht can't we that... why do we often perceive aliens as something stronger than us or hostile...or as a matter of fact something with a physical body ....
It could be anything and we should keep our understandings about them in the same status...
Why is he assuming that hearth is in the very tail of the distribution of planets which can host life? The problem is that we don't know that distribution and we don't know the probability for each of those barriers. How can we state that a barrier has a 1 in 1000 probability if we don't know the whole sample. It's like taking a glass of sea water and saying that in the ocean there are no fishes.
golden comment needs more likes.
he said purely for the purposes of illustration, he wasn't seriously estimating that is the true possibility of a barrier being passed he was simply stating that, given that the possibility of a barrier being passed is almost certainly higher than 1/1000, the chances of there being alien life out there is, apparently, extremely slim, perhaps enough warrant that we are the only intelligent life in the universe
the problem here is that we suppose the barriers to be around our understanding of life. There is a possibility to that in system that deemed harsh and inhospitable for us, it is actually hospitable for such sentient species or it could accommodate new form of life that we never know or cant even begin to comprehend at all. However, his arguments (the Speaker Stephen) are also solid, assuming all sentient species would need same sophistication as us human.
@Jakeed: ok, but then for illustration purposes this is a very strong assumption which cannot be verified by any experiment or available data. So we can discuss theoretically, assume what we might think and come up with any conclusion
@Nivodeus: I agree with the first part of your comment but I don't on the solidity of the assumption as it is based on a data which are very very limited observations of our universe. All the stars, planets and galaxies that can be seen today make up just 4 % of the universe. The other 96% is made of stuff astronomers can't see, detect or even comprehend and from the 4 % we even don't even know all the possible conditions under which the all the planets are. So, poor sample->poor assumption->poor conclusion
He clearly stated that he was just using 1 in 1000 for illustration purposes and he has no idea whether that's a good estimate. He didn't claim there's any support for that number.
Beautiful message in the end. With the amount of fortunate events that have occurred in order for intelligent life to exist, it is a real shame that life is not intelligent enough to take care of their special oasis in the middle of an almost infinitely and apparently empty desert.
But but stockholder rights and quarterly profits!
Everybody is talking about "Where are aliens?"
But nobody is talking about "How are aliens?"
"If the universe was the size of the pacific ocean, our search for aliens covers the volume of a cup of water."
- Me, just now
and thats only observable universe tho..
And that's the observable universe, and looking and searching this very moment. Imagine if you throw TIME in the equation. We are looking RIGHT NOW, but the universe is 13500 million years old, civilizations may have already been and gone, or developing, or whatever. Mind blowing
The One Who Knocks This was said by Neil Degrass Tyson. It gives you a proper scale of how much space we've been able to investigate so far. It means almost none. Therefore thinking that we are alone in the universe is plain silly.

I’ve always wondered, what if we’re first? Everyone talks about “oh the universe is so large there HAS to be others” well maybe, but someone has to be first and what if that’s us?
Derek, I have wondered about that myself!
I think the reason people say it's not us is because there are star systems older than ours by billions of years... I mean it's still possible but I'm just explaining the reasoning.
We are able to observe so little of the universe and yet we are astonished by it's size.
That's why more and more people are buying into this "Simulation theory". We simply can't wrap our heads around it all.
They are home, watching a reality tv show called Earth, what a silly question.
According to south park, yes.
on fognal
It's more likely that we are in an early access version Simulation without any alien race implemented. Stupid Life Devs, always trying to make an easy buck with those cheap and buggy simulation games.
🤣🤣🤣
It's not just where, it's also when.
Another possibility, we are the first. Someone has to be. Yes, the universe is 14 billion years old, but the universe, where stars and planets still exist, will continue for another 200 billion years or more. So understanding that time line, the universe is still in its infancy. Thus we are part of that infancy, and we in fact could be the first intelligent life in the universe.
@@misterdog8346 Nah, Just like evolution here on the earth, evolution of the universe will weed us out as a defect, and the universe will become much better after we are gone.

Plus, I'm not sure we are even "intelligent" life, given the current state of things on this fragile Earth.
Glad you liked his talk. He is eloquent. However, he doesn't know any more about the subject than either of us do. And I don't claim to know the answer either, but the sheer numbers of stars planets and galaxies make him most likely wrong. Very wrong. Remember Arthur C Clarke's 1st law: "When a distinguished but elderly scientist states that something is possible, he is almost certainly right. When he states that something is impossible, he is very probably wrong.”

It's really surprising what we are talking about and what we're expecting.
There are some questions without an answer respectively without the right priority.
1. Why should alien civilizations be interested in contacting us? Are we interesting enough for a conversation or small contact? Are we peaceful enough? Are we united? Who should be contacted? Which Goverment? Who's neutral enough and would not try to use the opportunity for an egoistical purpose?
2. Would an alien civilization need to contact us? What's the benefit of contacting us? Are there more disadvantages or advantages for the aliens? Can they trust us? Would we trust us?
They know everything about us. Why? Almost 100 years of TV and Radio. They just needed something like a satellite and few small drones and not more. These are things we could do with our primitiv technical standards of our time. If alien should be able to come near to earth they should have a distinctively higher technical level.
Our governments are liars, we are liars. The most people are full of anxiety, hate and egoistical wishes.
The aliens would be idiots if they would believe any of the lies of the governments.
Maybe one day in the future they will contact us, however, this day might be too far away for us or the next two generations.
We want a contact, we should stop bombing other nations on behalf of fighting against terror and enemies which we created and controll by ourselves. We should focus our time and energy on our planet and our neighbor planets. Rescuing earth and colonialising Mars and Moon without a military option would be the next step.

Thanks for the explanation.
Kein_indianer, You might also think of it the other way around. That is, why would we want to contact distant civilizations? The distances involved are so vast that anything we could get from a distant intelligence would not be worth the trouble of getting it. People seem desperate to know that we are alone, or are desperate to know that we are not. But just what do we do with the information if we find what we could be sure was a definitive answer? If those who are watching for such things were able to announce tomorrow morning that they had detected, and were able to prove that they had detected, what for dead certain is intelligent life in deep space, what difference would that make? I mean, what concrete practical difference? Does that make life better? Or worse? You can say that it will be satisfying to have the answer, but that seems to me mere curiosity. I can't get excited about satisfying that.
your abosluteley wrong there, just the mere fact of recieving *any* kind of communication from distant intelligent life would change the mindsets of millions if not billions of people which would filter down to the way people individually or collectively think,do,invest in or even ones fundamental core principles might change (i know mine would)It would absoluteley change our way of life as we know it.
of course that is if the guv-ment decided to even release that fact to us mere peons, on the pretence of *protecting* us.

"We're the creatures who got lucky" implies that there are other creatures who did not. Even he cannot really believe that life is all that unique.
Point
He said he believes we're alone because of the sheer number of barriers. Not that life is unique.
@@kenbrunet6120 Indeed. Still, imho it's a bit naive to BELIEVE that we are alone when we've sampled like 0,000000000000000000000000000000000000001% of the galaxy. I probably put too few zeros in there, but you get the point.
@@georgexanthopoulos3003 But the point is if life happened elsewhere then looking at 0.00000000000001% of the galaxy would in fact bring up evidence of aliens. We haven’t actually done that though, we’ve looked at other galaxies and when scientists expected to see some with dimmed light, from them harvesting energy from stars, they saw nothing that wasn’t completely natural. You only have to look at 0.00000000000001% of the ocean to see life, just as advanced aliens would have already colonised the galaxy, if they could exist elsewhere.
@@tomben6180 Not it wouldn't. You find life in 0,00000000etc. of the ocean because life is abundant on Earth. Nobody said alien life is abundant, only that it's not as unique as some may think.

Forget about the IF we are alone question. Lets just say that we ARE alone in the universe. The vast universe ALL empty, just US here. Wouldnt that make us , the human species, FAR beyond valuable?! How unique we are. How rare and special we are. It doesnt take much to notice it. Just look at the creation of babies. The growth and learning patterns of children. The intelligence and ingenuity of man. How well and adaptable our bodies are designed.
I think most people are looking at our existence from the opposite end. NOT how small and insignificant we are, but on the contrary , how unique, special , and awesome we all are.
That's basically the theological/Biblical view, where the Universe was not meant to be a "zoo", teaming with life just waiting to be discovered by us; but rather more of an "art gallery", with the exception of one place (Earth) serving as the location where the "artist" decided to physically represent Himself (mankind/life) even to the point of eventually injecting his very self (Jesus) into this same creation. Bible says the whole creation fell in Adam by his sin, which would be profoundly unjust to any aliens "out there" who had nothing to do with mankind's original transgression, yet made to suffer the same effects.
Please listen to the Matilda O’Donnell Macelroy narrative and this will all make sense.

I love Isaac Arthur's channel but regarding UFOs he has talk about UFOs but obviously has not spent any time studying the subject matter. I have spent a solid year studying the subject as an engineer and I am convinced there is something behind all the smoke. Anyone who actually studies the phenomenon comes to the same conclusion, 5-10 percent of reported sightings, and I mean pilots, radar operators, police officers, or large groups of witnesses some times even entire towns are not dismissible.
At 11:44 he states: “I think we’re alone.” And in our solar system we are. We have to be an experiment of an advance civilization to see how we turn out. The “creators” will either advance us or let us kill ourselves as not worthy of advancing. Let’s prove them wrong!

What really terrifies me is not the possibility that we are not alone, but that are perhaps the first ones.

What if they ask the same questions about us. What if they're out there they just don't and won't know about us
They would be looking for us in many formats to low in technology or to high to detect us so in the same logic their conclusion would be no life in the universe
@@davidarriaga6643 If they discover us, there will be evaluation of our technology. If we are lesser than them expect invasion and colonization from them. If they are lesser in technology, they will avoid us. All this is one big IF
An Alien from outer space well if they are able to detect us and decipher whether our technology is more advanced than theirs or not you’d think the answer is pretty obvious. But I don’t think this would necessarily mean an invasion. Would we invade if it was us with the superior technology? I’m not sure, especially if it was the inky encounter we’d ever had, I don’t think we’d want to destroy it or them.

Every civilization beyond 100 light years distance from our planet will not notice our presence, because our signals have not
reached them yet. And our Milky Way galaxy is up to 200,000 light years in diameter.

Before we saw the first planet around another star, there were people that were ABSOLUTELY SURE, CERTAIN, POSITIVE that there were NO OTHER PLANETS in the UNIVERSE!!!!! THE WHOLE UNIVERSE!!!!!!!!!
THEN we find out, not only are there MANY planets, but that, ALMOST ALL STARS *HAVE* PLANETS!
The difference dead objects like planets and living beings is that dead object does nothing to catch your attention while a livings leave marks of their existence absolutely everywhere. That means that either there's no aliens or they are equal to us or below when it comes to technology.
We could have 10 times more technology, no one further away than ~100 light years would know we're here.
Do you have any idea how hard it is to notice a planet that is only 40, 30 or even 20 light years away from us?
I could be wrong, but so far we've only been able to see planets that are 4 or 5 times bigger than we are, as it is.
Also, how many times have we been to Mars, and JUST 3 weeks ago they found a water lake under the polar (carbon dioxide, dry) ice there!!!

They are saying that 2, 3 or even more of the moons of Jupiter and Saturn combined MAY have microbial life on them.
Imagine, possibly FIVE places just in *this* solar system may have or had life on them.
the argument isn't about whether or not we would notice life. you're misinterpreting what he's saying. he's saying that the chances for life forming in the first place, based on the information we CURRENTLY have, seems to point to many walls that would keep interstellar life from forming at all. it would only take a single species that expanded across the galaxy for us to find some sort of evidence. yet we haven't seen even a whisper of a trace of alien's. the problem is that if there were even one interstellar species - which you would think would happen in the billions of years the universe has been around - we would have noticed them.
What *precisely* did he point to that says "seems to point to many walls that would keep interstellar life from forming at all"? And, just how many "walls" were there?
I'll help you with a few.
1) The Earth has a day of the length it has.
YAWN. Mars' "day" is 24 hours +37 minutes.
FAIL.
2) The Moon is making the Earth have a stable 23.5 degree tilt.
YAWN. Mars' tilt is slightly more at 25 degrees.
FAIL!
3) We need a Moon.
YAWN. Mars has 2 moons. Two teeny tiny teeny weeny moons that are literally of no consequence... Oh, wait, one of them WILL "fall from the sky" which could POSSIBLY wipe out all life on Mars, if there were any there.
YAWN.... EPIC fail!!!!
So, does he have any other CLEVER reasons of why we are "alone"? He CLEARLY doesn't understand, big, and I mean REALLY REALLY BIG numbers. His brain IS "teeny tiny teeny weeny" as the moons that Mars has. :-(
The problem is abiogenesis. The biologist Robert Shapiro estimated that to create a bacteria from random processes would happen once in 10 to the power of 40,000. He thought there was some unknown process that greatly reduced the odds, but maybe not. We might just be the result of the stupendous random occurrences in an infinite universe.
Of all the debates and talks i have heard and watched to date.This is the one that makes sense in the real world.We are the ones that will civilise space.If we dont destroy ourselves.
like every Ted Talk, a great deal of talking without actually saying anything
lol. yes
About 15 years ago I saw something in the sky. I stared at it for a couple of seconds. It moved from one place to another like nothing. I guess the speed of light. It's difficult for me to think we are the only ones here in the world.
Yep, those who have seen an object darting around like that, know it isn't something normal. Or at least we have never seen anything like it, ever. I too have seen one similar to what you describe, but I saw mine in about 1976. If I saw one today, I would chalk it up to us developing some type of anti-gravity technology, but all the way back in 1976, without sophisticated computers, come on! I hope before I die, there will be some type of concrete explanation of this.
I like the way this guy said he saw a saucer in the sky as a kid and just probably misunderstood what it was, That's the lamest argument I have ever heard from someone who is supposed to be knowledgeable. "I must have been mistaken". What else do you think it was, hotshot?
@@iamacepaul The correct answer is to say that you don't know what it is (its unidentified) and move on. The lame thing to do is claim its aliens.
Interesting scope. Very well laid out. Thank you for your time. 🖤
This is my 1st simply flat TED talk I ever listened....but bring 's about 1000 questions in my mind .... quiet interesting 👍🏻
There’s billions of stars and planets in each galaxy alone, and there’s over a trillion galaxies in the observable universe, and people think we’re the only intelligent life? The opportunities for life is just too high
For life yes, but not necessarily for communicative intelligent life.
Rudy Colludi why not intelligent life aswell? there’s hundreds of trillions of planets we can’t be the only intelligent life to spring from it
@@sammm186 and what if we are the only intelligent form of life in the universe? Is that a bad thing?
@@wazgoodjj 1 in a trillion is not a good example. He claims there is a minuscule chance to surpass these proposed barriers. When you are comparing even .000000000000001% chance to infinity then it definitely has happened already or definitely will happen. Thinking of our planet as an incredibly complex and rare pattern. Patterns repeat indefinitely when your looking at the universe having an infinite amount of chances to do so...So silly to suggest we are alone.

You know what is scarier than either the idea that we are alone in the universe or the idea that there is life so advanced that we arent worth their time? The idea that there is other life out there but that we are currently the most advanced, and 500,000,000 years from now we are the leaders of the universe and going about the universe treating its life and resources as we do our own here on earth.
Saphire Throated Carpenter Ant or the aliens are the same and use all our resources.....Or they may eat us 😆
I don't want 500 million years of existence for humanity.
That we are not worth their time does not make them invisible.
A K3 civilization is so massively obvious that their existence even billions of lightsyears away would have been clear since the 60s.
+Sudip; what is "humanity" in 500 million years anyway? Maybe we evolved so differently that we look like a Star Wars esemble, including uplifted chimps, elephants and ravens.
I just want a mass extinction or the judgement day to stop our species' progress well before we evolve into omniscient overlords.
It's much better to go extinct while we are asking questions, fantasizing about the mysteries of creation, rather than knowing everything and unable to question or wonder because there's nothing left to wonder about.
There will always be something to wonder about.
Even if you had all the knowledge you could obtain through science ( ≠ omniscient) you could still wonder about how the story of your favourite author might continue next week.
We are "the Ancients". The universe has existed for a long time yes, but getting past all the barriers is so hard that we are the first. In millions of years some race who made it to the level of travelling between stars will find our planet. And they will know that someone else DID exist, but long long ago. Our ruins mostly gone because of entropy and all that time
Pretty bold assumption.
I was wondering where he was going with the speech but I knew he was leading us to something. Awesome message. Thanks Stephen!
