- Are We Alone in The Galaxy? Brian Cox on Alien Life
Subscribe to Science Time: / sciencetime24
It is one of the most intriguing questions in all of science...Are we alone?
There are about 300 million planets in our galaxy alone that might support life as we know it. By the sheer number of these planets it can be argued that we are most likely not unique in the galaxy. Brian Cox thinks that there must be intelligent civilizations out there, although they might be extremely rare when we consider the rise of intelligent life here on Earth.
Imagine intelligent civilizations are prevalent throughout the lifespan of the galaxy. There had to be a first civilization. Asking: Are we alone? Only in their case the answer would be, yes. But maybe, that civilization is us.

What is your answer for the Fermi paradox?
All of the smart things hide from stuff like us and I don't blame them.
with billions of galaxies and many more to come, with trillions of stars and more trillions of planets without exaggeration, that gives around 100 billion planets that can support life, now that life has phases, 1 2 3 4 5 6 7, ( Civilization type ) and as well what type of intelligence they have and Ambition. doubly humans are alone, humans are just too Hostile and anti friendly cooperation mindset, once that changes et´s will say once again hello, I promise
The universe is almost 14B yo, but for the first few billion years life was impossible imo (the first supernovae gave us certain elements), so only these last few billion years conditions were right and not everywhere (not too close to the center of the galaxy, not too far). That's why I believe we are among the first civilizations to appear on the scene. This combined with an incredibly small chance of developing intelligent life (as Cox said and I believe this aswell) and a certain cosmic lottery of getting a planet which is stable enough for a very, very long time for life to develop, well this leads me to believe that there just aren't a lot of civs out there. I hope I'm not wrong about this. I don't think bumping into other developed civilizations will go well for both us and them.
Space is massive.
We are not alone ☕🍃
I love listening to Brian Cox. Somehow his voice always seems like he's smiling and really passionate about the subject.
He does have a wonderful voice, but he’s vastly ignorant of the latest findings in physics, cosmology and biology. You can gather the world’s leading scientists in a pristine lab environment, give them everything they need and they still can’t create one living cell. Any person who tells you anything different is ignorant of what life is or has changed the definition of life to include rocks etc
@@alanbriv I'm sure you know better than him.
@@alanbriv That doesn't make any sense. Just because we haven't figured out yet how biogenesis happened on Earth in the past, or how to do it today, doesn't prove it didn't happen. Take atomic fusion for example. We know it can occur because we see it happening is trillions of stars yet we can't make it happen on Earth in lab (although we are getting closer year). Does that mean it is impossible? Of course not.. And I would be curious to read these "latest findings" you mentioned that disproves the theory of biogenesis.
Until he starts talking politics!
It’s all choreographed. Most will not think and read for themselves. “How can I not believe someone who is sooooo passionate and smiles a lot?” 🙂
I've always believed that there is plenty of life in the Universe. Problem is that everything is so far apart that its virtually impossible to reach another civilisation.
Impossible for us yes but not so for something like a.i
Closer than you think
The evidence suggests that is little chance of life elsewhere in the universe.
Check out the updated drake equation.
There are 13 known requirements for life as we know it.
The only planet we know of which has all 13 is earth.
The next closest we have found has 2 of the 13.
The majority of galaxies can be ruled out from supporting life due to the radiation they emit for example.
Plus the universe is expanding at a great pace with that in mind if it takes 1 years to reach a certain place normally the constant expansion will make the time increase significantly..
Impossible for us to reach them, but not for them to reach us.
The universe is unimaginable huge. Billions of galaxies each with hundreds of billions of stars each with multiple planets. Finding life somewhere else in the universe is not only likely but inevitable.
There may be life of some sort out there but the distances are far to great for us ever to find the answer.
And the evidence of them that we see from earth will be prehistoric. Who knows what or where they are today
... and if we knew about them in advance may prefer not to meet them.
Would that be the same inevitability where 30 million Euro. lottery tickets are sold but no one hits the jackpot?
@@colinc.8742 how many euromillions combinations are available?
My theory is that there is intelligent life all over the galaxy, and it is all alone, in the sense that there could be no possible communication or detection of other civilizations because of the distances involved and the speed of light barrier. Lets think about it a different way ... Suppose we could position our self anywhere in the galaxy we want, and we knew exactly where earth was ... How far away could we possibly be and yet still detect signs of intelligent life?, even if we knew exactly where to look and exactly what to look for. Keep in mind that data we could possibly use to detect life (radio, atmosphere, etc) can't possibly travel faster than the speed of light. So depending on your "intelligent life detecting approach" it suggests there is a maximum distance from earth beyond which it would be impossible to detect intelligent life on earth. Even if you knew it existed. Maybe 100 light years. Maybe 200 hundred ... Much further than that and the data you are looking for would not have had time to reach you yet. But these are crazy insignificant numbers when you consider distances on a galactic scale. And lets not even get started on inter-galactic scales. And of course, there is the "when you look" question. Anything you could possibly detect would be a view of reality that is many years out of date. Like thousands or millions or billions. of years More than enough time for any detected civilization to have vanished. And for new civilizations to have emerged whose "clues" have not reached us yet. TLDR; - unless you break the speed of light barrier, we will always be alone. Even in a galaxy full of intelligent life. BTW - is there intelligent life on earth? Gotta wonder sometimes ...
Let's just say if we are not going to multi verse and beyond scale and just stay on interstellar the question might sound this way. Even though we consider ourselves intelligent, for aliens we might to be for them. It's not only about technology, it's also about our history, culture, literature and etc
please overview the evidence that already exists from various military branches spanning decades and let's get beyond this 'maybe' framing. soft disclosure is already happening by the US navy and others. it feels so frustrating to be framing it like this still because of what is considered acceptable discourse. cases like rendleshsm forest and phoenix lights are quite cut and dry. have a look.
Thanks for sharing. To put things in perspective I want to share a quote from Sir Fred Hoyle (one of the twentieth century's great scientific thinkers. Institute of Astronomy at Cambridge/UK):
The idea that life originated by the random shuffling of molecules is “as ridiculous and improbable as the proposition that a tornado blowing through a junkyard may assemble a Boeing 747.” He calculated that the likelihood of life beginning in such a way is one in ten to the power of forty thousand. (He illustrates this by examining the chance that two thousand enzyme molecules will be formed simultaneously from their twenty component amino acids on a single specified occasion.)
That’s 1 in 10 followed by 40,000 zeros :)
@@alanbriv th-cam.com/video/saWNMPL5ygk/w-d-xo.html And the rest of Life Beyond series, it will inspire you.
@@alanbriv True, but Hoyle was not the most accepted, rational or objective person in this regard. There is little support for his beliefs in the science community, with respect to the origins of life. He was also a proponent of a theory that viruses like polio, mad cow disease, and the flu pandemic of 1918 were of extra-terrestrial origin. So I would suggest that his calculation of the odds involves a lot of highly subjective, unverified, and even disputed assumptions.
The technology aspect is interesting to ponder. If you look back at our own recent technological progress, radio communication is barely over a century old. Before we had radios, the fastest communications system was the telegraph. Imagine someone from the 1880s, they would think the telegraph has to be the most efficient way to communicate, and that surely, if there were intelligent races out there, they would need vast wires connecting planets to communicate. Even today, radio communication is waning as better technologies exist, so a civilization even a century ahead of us might find our ways of communicating as antiquated as we find telegraphs. The universe may be buzzing with messages, but we haven't discovered what that technology is just yet.
Excellent points! We haven't even left the starting gate by comparison to incomprehensible older civilizations. It is pompous at the very least for us to believe that we amount to as much as an ant relative to intelligent life merely 500 years ahead of us technology speaking (not to mention far older than humans.....
....and when was the last time you (or anyone) paused to waive & say "Hi" to an ant?
🙂
@@chrisklinetob7389 I tried, but the ant doesn't care! 🙂
According to General Relativity nothing is faster than light, which basically is the maximum speed of information. Yet I still hope Einstein wasn't completely right else we live in a very boring and lonely Universe.
@@danielekirylo While nothing you say is incorrect, I just wonder if our understanding of physics will find a way around it. Not even too long ago, the sound barrier was thought to be impossible to break, and with the technology they had at the time, that was probably true, but then science figured out how to make it so, and now breaking the sound barrier is nothing remarkable anymore.
I am actually an alien, people don't believe me when I say this, but I come from a star-system called E50067-C, and we eat each-others feces to stay alive.
Every time I think about how much we’ve advanced as a civilization, it makes you just wonder what the future is going to be like. it makes me sad to think that our species doesn’t even live to a century which is literally nothing in astronomical time. Just imagine the things that are out there it’s incredible.
But let's say reincarnation is true and real, and that every time we reborn again, we reborn a hundred years increment into the future...So eventually we'll be able to see and witness the future that is a 1000 or more years ahead of where we are today. At least that's what I'm hoping for..lol
I course we are not alone! The universe is just too vast and infinite to be otherwise. The only question is how far are they away from us?
It's a very big universe.The premiss that there would be a first civilization is, to say the least, shortsighted. One could imagine life evolving on thousands, maybe even millions of planets simultaneously.
And they are all hanging out at the Creature Cantina.

I just want Brian Cox to sit on an easy chair and talk about physics to me at night. I would sleep so good and have some cool ass dreams.
He does have a gentle voice.
Me too.
I once told a work colleague as a youth l didn't believe in aliens ghosts etc but now as an old man I've been seeing such objects all my life.
There is a difference between life and conscious life. I believe we are the only conscious beings in the Universe and are alone so it is so important to appreciate life and the beauty of Earth and really enjoy it all.
I totally agree.
space is simply so vast i refuse to believe we are the only example of life in the entire universe it just makes absolutely zero sense
When you understand the conditions required to allow life as we know it, it is no longer a surprise that we may well be the only life in the universe.
In fact, it's actually a surprise life exists at all.
Check out the updated drake equation.
@@andrewdouglas1963 many equations were wrong (incomplete), also Einstein's equations of General relativity were wrong until they were corrected and considered right, after multiple iterations.
Said this, what type of life, because bacteria are life, so are you referring to complex life? Highly intelligent life?
@@danielekirylo
By life I mean the condition that distinguishes animals and plants from inorganic matter, including the capacity for growth, reproduction, functional activity, and continual change preceding death.
why? and assuming in something which is not proven makes perfect sense?
@@andrewdouglas1963 drake equation is a joke and should not be used as a scientific tool, he said so himself. its just a guide based on wishful thinking.
I do belive that somewhere there is intellgent life, but the distance between is so big that its impossible to detect each other
You dont have to travel far, there is already intelligent life on Earth.
By design! If we can’t see what’s under our own noses, how can we see anything anywhere else? There’s tons of life everywhere!
@@CatsInHats-S.CrouchingTiger yes ,it would be a waste of space if we were the only intelligent beigns capable of experiancing the wonders of the universe
finally we're asking the right question, focusing on if there's life in the galaxy is the only question that we can hope to answer anytime soon
Lol what? That makes no sense.
@@nurulqwe i meant that asking if we're the only living world in the galaxy is much more practical and focused than asking if we're the only living world in the cosmos. If u think on a cosmic scale the answer is practically obv.
@@doodelay Why would that be obvious? If we can't even find more life in our own galaxy, then chances are we won't in any other galaxy. In the end though no one knows.
Well without fully exploring the galaxy, you can't say for sure if we're alone in the galaxy.
Agreed. My problem is with those who believe inorganic molecules suddenly come to life without a cause. That is intellectual nonsense on steroids. Darwin had absolutely no idea of just just how complex living cell is .Sadly or intentionally most biology textbooks push exactly what Mr. Cox is saying. You dare not use intelligence as a possible cause for intelligent beings?
No matter what, it's beautiful and we were lucky to be aware of it.
We are aware in a fashion.
It's amazing to think how long it actually took to construct earth into a living habitat and even scarier at how quickly we are destroying it.
Don't worry, once we are gone. The Earth will renew itself. The Earth isn't in trouble, we are.
You really need to stop this mind torture. We are not destroying the earth. We could look after it better. But we are not destroying it. Stop spreading falsehoods
Earth will forget we were even here at some point. It’s humanity that’s at risk.
We aren't destroying the earth, we are destroying the ability to live on earth.
A billion years of beauty ruined in 2 generations 😬😬
I love how when these experts are interviewed in a future this is your life program you find out that they were winging it and needed to read up on the subject, That would probably be more accurate for what we actually know when all is said and done?
1) We can only see a small snippet of the universe today. 2) The universe is expanding faster than the speed of light.
So we will never see any more of the universe than we see today and the outer limits of what we see today will start disappearing.
I'm still waiting for them to discover intelligent life on earth . . .
Boom roasted
Thank you
They probably took a recent look and are considering pulling the plug on the human experiment. Can’t really blame them, we over populated, we polluted, we rape, pillage, and burn the environment at every opportunity. We have learned how to play with nuclear technology, build our own viruses to destroy our own species ( COVID 19 and it’s never ending variants). Now we are considering a parasite type invasion of other planets. Wouldn’t blame them if they introduced their own virus to exterminate humans.
This comment is to this topic what “it’s not the heat it’s the humidity” is to living in the south.
Yeah well what intelligent life is on earth may be gone sooner than later with how stupid we are with the wars that are going on. Unfortunately I see us destroying all life for stupid reasons. So we may never know if there is life elsewhere if we continue on as we are
Don't forget the universe had to age through 1st and 2nd generation stars in order to have the necessary heavier elements for life. We may well be one of the firstborn.
Yeah, we need to lick all the good planets before the other first borns get to them. First dibs
@@mackenzieallen LOL
Early stars had short lifespans. Big dogs die young and the first stars were super massive. So they didn't last very long. Maybe 100 million years? We think density may be a problem. In a densely packed neighborhood you do have to worry about the neighbors making noise. Especially when that noise is a super nova. We live in a quiet neighborhood. Our civilization rose in a particularly stable time frame. Things have been pretty good on Earth since the last Ice Age.
The question should not be “are we alone in the universe” the question should be “where are they”? However finding and pinpointing where other civilizations are does us little good. We still wouldn’t be able to communicate with them. The nearest intelligent beings are most likely hundreds if not thousands of light years away from us
You do not only have to worry about where they are but also when they are too. You have to be in the right place at the right time or you miss your connection.
Good luck with finding any, any time soon.
Like about the next hundred years.
But found, it will be.
Recognized?
Who can know?
@@Fritz999 I just read an article about the rover on Mars heading up an ancient river delta looking for signs of past life. Maybe at one time there was life on Mars? But if there was it's not there anymore. Still, finding the remains of life would be pretty exciting. It would confirm there's life elsewhere.
What an amazing and outstanding chap Brian really is 👍 I've just watched The Planets and have to say I was amazed by it all! Well done buddy 😊👍
Few years ago i had an encounter while on a canoe camping trip with my son, it was about 3.30am and ide crawled out the tent to take a leak, there wasn`t a cloud in the sky, it was pitch black but you could see every star in the sky from this field we`d camped in, as i walked towards a few bushes i felt something like a static charge and i looked about and for a split second i saw a bluey green light just above me, reminded me of what a plasma discharge looks like from a tesla coil, i looked straight up above my head and saw a distortion in the sky, i could still see the stars but it was like i was looking at them in the reflection in water, they shimmered, only way i can describe it it was like the predator when he engages his invisibility device, this distortion was moving real slow, eventually it passed over head and as i looked more at it and the further it got away it started to see a solid object, eventually i saw a leading edge to a disk shaped object, it looked like brushed tin or pewter, no sound at all apart from a gentle hum which i could feel in my chest, like you do at a rock concert when the bass kicks in, there was no engine exhaust, no rotors or ailerons or anything you`d identify as an aircraft, it was seamless and looked like it was injection moulded from 1 piece, i guess it travelled about half a mile away from me, over the river we`d canoed down that day and all of a sudden it shot up vertically that fast ide say within 2 seconds it looked like just another star, this was in the UK at a place called Ironbridge near telford, i`ll never forget that as long as i live
Did ye, aye?
@@generalyellor8188 this happened mid july of 2019 i believe it was a wednesday because on the tuesday we`d canoed down through Welshpool to a place called Atchem, it`s a killer of a day about 27 miles so we were knackered and slept through that night so yeah it must have been Wednesday because that was the stretch of the river severn we would have reached Ironbridge Gorge and rapids, ive no idea why i woke up at that time, i never did take a leak i just lit a cigarette and sat on the canoe and hoped it would come back but it never did, only time in my life ive experienced anything like that, was amazing to see.
The aliens have microchipped you! How does it feel?
Wow. Unbelievable story. I definitely believe we are not alone but I never experienced what you have. I'm a huge fan of Acient Aliens series and been following it for years. Check it out if you have not. Thanks for your story. I know there are plenty of you out there who experience it
Once when I was camping I got buzzed by a fighter jet flying below tree top level. The person I was with saw it too. Then the next day that same flight happened about a mile south of us. Because the pilot saw us too. I can't say I felt anything though. Even though the plane couldn't have been more than a few hundred yards from me at its closest. I saw the guy in the cockpit. I think they were doing radar defense penetration testing or something. Or maybe the guy was just nuts? So yeah you can see some weird stuff camping.
At 3 minutes the narrator says, “ I don’t think that there is anything special. Life is just chemistry……” If that is the case why have they not created LIFE in the controlled environment of a Lab?”
Quote: “Origin-of-life researchers now know that Stanley Miller’s simulation experiment(1953)has little, if any, relevance to explaining how amino acids-let alone their precise sequencing, necessary to produce proteins-could have arisen in the actual atmosphere of the early earth.”
‘We can’t do it so therefore it’s not possible = God’ is this not just personal incredulity?
@@nameatrandom9234 Friend, think: with all our scientific knowledge we have gotten absolutely nowhere when it comes to creating life. Dr. James Tour has 13 video lectures on abiogenesis.

Not in a trillion years. Spontaneous generation is a myth. I am a theist. I am a Christian. No apology. Do you actually believe that a butterfly, whales, DNA, fine tuning of the the universe, the human brain and eyes are all accidents? Are you a freak accident of nature?
On the God issue: if there was ever a time when there was absolutely nothing what would there be now? Keep in mind that prior to the Big Bang there was nothing.
I still want to encourage you to watch Dr. Tour’s videos. He will personally respond to any questions you might have. Life, even the simplest, is vastly more complex than you can imagine :)

Love documentaries like this. ANything with Dr. Brian Cox in it, is worth watching right when I find it. I've loved all of his documentaries, because he is such an incredible thinker.
To be honest he is a bit more like a parrot than a thinker, he hasn't discovered anything new everything he says you can find it in Astronomy books. What he is good at is explaining to the ignorant in a simpler way making it easier to understand.
We, humans and non-humans, have been living alone in the universe that we know. The dinosaurs knew it until most died out because the earth made them ended, likewise, many previous strange civilizations once existed then vanished as earth changed again and several again in its history with the moon, the sun, and the sibling planets. Is there any civilization existed beyond our universe? Maybe because our senses are bounded by 3D.
There is an assumption made here that geochemistry had to develop into biochemistry. Problem is we have NEVER been able to see that happen in the test tube despite trying over and over again. The assumption is that if we take the right chemicals, place them in a test tube, keep shaking them up over billions of year that eventually life will form. Unfortunately, that violates the second law of thermodynamics which says that things in order will become more disorderly arranged in time. Take a puzzle the is put together and placed back in the box. The more you shake the box, the more it will break apart given more time. You could take a puzzle box and shake that for billions of years, it would never put itself together, it will remain randomly arranged. Now the theory also assumes that you add energy to the experiment, so the theory is that if you add in a bolt of lightening to the test tube that will be the energy that powers the random to become organized. This admittedly could be a possibility but we have yet to duplicate this in the laboratory with adding all kinds of various scenarios available in the lab.
Even if there is intelligent life, how do they get past the time/space problem. The maximum speed a particle can travel is the speed of light and the faster it travels its mass increases. That is a huge problem to solve. If we could travel to the closest star proximal centuri at 1/2 the speed of light the round trip would take 16 years. However the time passed on earth would be 32 years.
Your initial point was about entropy. While it seems intuitive that entropy would render biochemistry naturally impossible that is not the case. In fact, entropy is a necessary presupposition of chemistry and biology. It's logically sound. That's what makes the theory so compelling!
Where did you get the 32 years figure from? Objects
Traveling at half the speed of light don’t age half as fast
Oh, so life can't possibly exist !?
Very well said :) 70 years of shaking the test tubes in a lab and still no progress whatsoever.
And to think that from that lightning strike ages ago came DNA, butterflies, whales, Einstein ,Shakespeare and Santa Claus
By the way macro evolution is not a theory nor is it science - it is a philosophy.
@@alanbriv 70 years is not millions of years....or don't you understand that !?
they said life is just chemistry, but why haven't any of the life creation experiments created any life yet?
Brandon, lifeless molecules came to life! Makes sense to me :)
Cox succulently put it best : "IF we last" !
For centuries, mankind thought Earth was the center of the heavens, not because they were dumb but because they had no means to prove anything else. It's proven Earth isn't, but our vanity still makes us even bother to think we are the only "intelligent" life in the universe. Your home isn't anything unique, why would you think you are?
I think there are more civilizations in the galaxy...and some kind of life in all galaxies. They just have the same problem we do.....distances and time travel.
It seems highly likely. I doubt that we are the only planet with the right conditions.
stick to science fiction.
@@Chineseguy001 hey, what was science fiction decades ago or just a few years ago is reality now. Apply that to aliens, space travel etc. get it now? Someone in the 1800’s would think a cell phone is science fiction and couldn’t even imagine it, yet here we are today.
@@GeorgeZimmermen then are using too much imagination, stick to reality.
@@Chineseguy001 was a cell phone or computer reality hundreds of years ago? Was it even something anyone could fathom or imagine?
The question is not whether life exists in the universe, but whether we coexist on the same time plane. We observe our universe as it was thousands of years in the past. I think the most exciting aspect is that we can prevent our own extinction by branching out into the stars. Ironic as it sounds, humans may be the first extra-terrestrials.
I never thought about that
The universe works like a giant quantum computer and it was programmed to do what you see here on Earth and this is the only place in the universe this has happened. Even though Earth contains semi intelligent life you will find no other in the universe. Understanding this you can see how sacred the Earth is. This knowledge and wisdom has made me the wealthiest man in the universe. When you see the universe as she truly is she will let you know that she sees you seeing her. This will scare the hell out of you at first but you will soon see there's nothing to fear 👁
I can see earth being the only place with complex life in the universe. Is there unicellular or microbial though?(algae, fungi, bacteria analogies, etc) I think even microscopic life would be fascinating
@@jennanapolitano493 it makes sense that there should be life in the universe other than just here. With billions and billions of planets and stars it surely seems that there would be life elsewhere. It could be life will rise in the future somewheres else and we could be the first to arise. I definitely could be wrong but I have a deep gut feeling that this is it. This doesn't make much sense to me but it is what I am reading from the universe. I do know for a fact that there is a lot more to this reality and life than what any man can imagine. I don't really understand why the universe hides so many secrets from us and because of that I really try to stay open. I am an old soul Elder the kind of person that the wild animals have no fear of. I also see things in this reality that most people cannot see. 👁
We should all act like we are alone.
There is no one coming to save us from ourselves.
"There's been so much time." Exactly what I keep coming back to when pondering this. If our civilization "only" lasts a million years before it destroyed itself that would have been .0001 of a % of time of the whole scheme of things.
But the amount of time since the first starts where born compared to the time the universe will last we are very early
The universe is still in its infancy. It cannot support life forever and life is only possible for a small fraction of its its total lifespan
We are alone in OUR particular Space/Time. The SAME applies to any OTHER Civilisations. Any Civilisation that become intelligent will inevitably destroy itself. The fermi paradox doesn't apply.
I've seen the entire discussion in the past yet it still fascinates me. Brian is a master of explanation using lightly constructed sentences with enormous complexity of thought stimulating the wonder of scale. For example, so complex life used a tool 500 years ago lets say, this paradox. What about a place that's "a million years old?" I laugh at the thought we would be observed as intelligent to them. What I am saddest about is, none of us will most likely live long enough to know the truth of "are we alone" 100% positive. I say we are not from a numbers pov.
Not necessarily. We could easily discover microbes within our lifetime, which would then give us our answer.
@@leafcomedy1541 True, and that would have strong indications about the possibility of really intelligent extraterrestrial life somewhere in the universe when you think about it, although most people obviously want to the question answered on whether we are the only species in the universe, or this galaxy even, who have made civilisations, in their lifetime. :D
I say we are unlikely to be the only species with a civilisation or a collection of civilisations in the universe. There is AT LEAST one other civilisation somewhere in the universe, but it is likely that there are countless of them in the entire observable universe, and even more so still in the ENTIRE universe.
It's a shame that when we do find the life that's out there, the general population wont even know anything about it. It'll be kept more secret than what happens at groom Lake.
Primitive life is probably very common, but intelligent space fairing civilisations are probably very rare - the universe is very young and we could be one of the very first to venture off our planet.
It’s impossible for us to be alone in the infinitely expanding universe. To say we are the only life in the universe is like throwing a grain of sand in the ocean and expecting it to be the only grain of sand
Where is everybody ?
@@jimmyzhao2673 The day i meet the first person from another world i would gladly ask them where they were.
It’s a very illogical question to ask, A hundred years ago people would have said you’re crazy and it’s impossible if you said we could go to space and today look what humans have accomplished.
So to say it’s impossible for other life to exist on other planets and think we are the only intelligent life is just saying that you can’t imagine and see the bigger picture of life and what is and could be possible.
Just learn to have a little faith, God never said that adam and eve was the first people ever made, God said, "Let us make man in our image, in our likeness. He never said let us make the first man he just said man. So that could mean he had made more people on earth or somewhere else
then why haven't we found any? everything can be explained away.
@@Chineseguy001 you have an unusually pessimistic opinion on extraterrestrial life which is at odds with a huge number of astronomers with far more credibility and scientific knowledge than yourself so pardon me if place my faith in people with much greater scientific credibility than yourself....Stephen Hawking believed in the existence of extraterrestrial life so why should anyone pay the slightest attention to your uninformed opinion ?
I could listen to this guy all day.
In this day and enlightened age, this is a question that no longer needs to be asked. 300 billion stars, and we're the only one? Come on! The same elements and chemistry are spread throughout the galaxy. Stable stars like ours are common place. All that's needed is time.
it seems unlikely. Life is unique to earth and we have to stick with what we know instead of making big assumptions.
People who say aliens aren't out there because we can't find them , or that aliens aren't interested in us because we're the ants of the proverbial ant hill hold an opinion I disagree with.
I think we are functionally alone. Beyond the observable universe probably lies 20 or more areas as big as we can see from here.
Beyond our time and space other intelligence must lie.
We see to be first here. Let’s save as many other lives as we can before Earths expires. The Clock is eternally ticking.

What would really be unsettling ,if we're all alone 🤔
I love Brian. I slightly disagree on the development of civilisations as guaranteed by time for the reason that there is a lot of opposition that can challenge progress, politics most crucially: we could’ve been farther ahead as an intelligent species if we listened to the scientists of the past more, like in the Roman era all the way to the classical era, even now.
politicians need to be payed more so actual smart people leave their carrier with a prospect of a similar pay check.
@@pogo6543211111111 then where would all the pay offs go?
Maybe if they were paid more and had bank accounts the public could see. Personally I think they all need to lose their heads.
I think considering the sheer size of the universe it's arrogant of us in the extreme to say we are alone. It is a completely different matter if we will ever discover or meet that life but I do feel it's out there.
Chances we are alone: practically 0
Chances we will ever meet other intelligent life: practically 0
Amazing video, very informative, thank you, and Professor Brian Cox's voice is so soothing and the way he explain things is really good.
The likelihood of intelligent beings that create civilizations existing has to be almost vanishingly small. We're probably alone at least in our local region of the galaxy.
Not even if it happen to us its abundant.
Universe is big, very very big. A star is needed for life to arise and sustain as we know it, and there are billions of galaxies with billions of stars in each, just in the observable Universe that is just a tiny speck according to the inflationary theory. Give a planet a goldilocks zone and things will pop off.
True
We must seed the universe with life.
It's very disappointing such a big question is explored here and not one word or shred of scientific curiosity is afforded to UAP's and the mountain of evidence buzzing around right under their noses. Simply Amazing
These 'follow the science' types never acknowledge UAPs. One could land on SETI's roof and they'd say sorry guys still looking.
Blurry videos are not evidence of aliens. Besides, they have been debunked many times.
@@ml5444 If there's so many out there, why wouldn't they just land and say hi? Blurry videos are not real evidence.
When Brian Cox says "If you imagine a civilization one million years ahead of us then they should have written there presence across the sky by now, We would see them" - WE HAVE for decades and we still are because i've seen with my own eyes but it gets discredited or watered down to natural phenomenon. They observe us as a hostile primitive species.
We’re most definitely NOT alone. Anyone who believes that is naive and ignorant to how big the universe is and most likely cannot grasp that exact concept.That we lack the technology to find/see living organisms in other places of the universe does not mean they aren’t there.
I used to be skeptical about Alien civilizations existing here on Earth along side Humans. The unimaginable distances between Stars?
With the advent of the cell phone, almost everyone has a camera. Fighter Jets from every Country have reported in, there are thousands of sightings a week. Underwater sightings. Locked into a gun sight, and Pilots weapons are neutered by What?

With all of the cameras prowling the planet now, why are all the UFO photos/videos so crappy?

Amateur astronomers have found thousands of meteors, and incredibly high resolution telescopes are trained at the sky every single night.

I can’t wait till we hear our first discovery from the James Webb Telescope. 😁
Same but I don't think we will find alien life. The telescope is just not advanced enough for that
Let’s hope the launch goes off without a hitch and if so let’s also hope it doesn’t have any problems like the Hubble had for the first few years.
Fingers crossed that all goes well...🤞
@@fisch0182 As I understand it the Webb will be able to detect elements in atmospheres. We won't be able to take pictures of cities. But we might be able to detect emissions. I've heard the Webb may even be able to directly image extra solar planets. It's a pretty powerful instrument. But we'll see.
Mathematically it's inconceivable... Currently with our technological development there's no way to truly know beyond theoretical bacteria.
Fermi paradox is such an egocentric way to look at things. If there is a more advanced civilization (Or multiple) out there, what makes us think that they are necessarily close to us??? Space is so infinitely impossibly infinite and hard to understand, that assuming that "we should be able to see something out there" is just senseless. I am sure there are civilizations out there, and while it would be AWESOME to be in touch, I don't think it will happen in MILLIONS of years (If our species survive that long).
I wish i could find the source of where i heard this theory but I once heard that what we call the 'observable universe' is probably the equivalent of a golf ball on the surface of pluto, with pluto being the actual size of the universe at its current state. When you think of it like that, and taking in the rarity for intelligent life, being alone in this 'golf ball' corner of the universe becomes much more depressingly likely
Wasn't it a lightbulb on Pluto?
@@paulnewman1356 nah bro, it was a pack of Newport light 100’s

Could also be that intelligent life always evolves enough to ultimately discover higher dimensions that are much more interesting than ours…Other dimensions are actually predicted by string theory.
Maybe we just live in the “lame” dimension .😂
Or they go the virtual reality route
wow, thats mind dazzeling
@@nicknderitu6013
I think “virtual realities” or “simulations” are human constructs of our culture. Kind of like how people in the 1950’s thought futuristic machines would have big vaccuum tubes and reel to reel tapes. Its all relative to the time. Our culture is big into virtual realities,video games and simulations right now,so i suspect that plays some kind of part… could just be a phase though…but i could be wrong,and its fun to ponder. The fact that string theory actually predicts other dimensions is also something to consider.Maybe Dark energy is actually the “force” of these other dimensions.
lol, if scientists dont find any life in this universe then the argument goes that we live in the "lame " dimension.
Until proven otherwise, life on Earth is indeed special.
Life on Earth is certainly special to me regardless of what else may someday be discovered.
I do believe as the fermi paradox suggests we are likely the only intelligent life in our galaxy but as for detecting intelligent life outside our galaxy, given the distance between neighboring galaxies of about 10 million light years, unless their signature is very obvious they will forever remain undiscovered
There will be life out there for sure, intelligent and non intelligent. But, because of the vast distances, even if you could travel at the speed of light, which is impossible by the way, it would take many life times or longer to travel to other worlds. So we have this little patch of space all to ourselves and it won't take us long to stuff that up anyway.
Impossible yet :)

@@PhiltheMoko we probably are.
@@2019freddie any reason to think so? Our current models are obviously lacking something, but they do have pretty fantastic predictive value for the vast majority of physical processes. It seems unlikely to me that they could be as accurate as they are while having the complete wrong idea on causality.
He says life originated on Earth and probably didn't come from other worlds. Based on what exactly? It's possible it started here in the oceans, but panspermia is still a possibility imo. It would explain why life got here so fast after the cooling down of the planet.
Based on shifting the seemingly insurmountable problem of how life can arise from non life.
There's no point in exporting the problem as it remains equally as problematic.
You can have all the 'suitable' planets you want, and all the components for life - but you still need a molecule that can self-replicate. Take, for example, the smallest possible molecule of RNA, say 500 bases. With four nucleotide bases how many combinations can you have and how many will self-replicate. The odds against it are enormous. It happened on Earth but the chances of it happening twice in one universe? Remote.
God I love Cox's accent and voice
All discussions I have seen surrounding the FP I have a tendency to assume intelligent alien life in a similar image to our own. With just one example (us) that seems a big assumption to me. The problem could be one of perception. Professor Cox seems to touch on this as well. Once we find the first one (or should I say second) then we may well start finding others quite quickly as our understanding grows. As we get our eye in as it were.
i agree, but i have a problem with mars. its cold very cold. 3billion years ago it had running water, 3 billion years ago the sun was colder than today.
surely it would have been colder.
I agree, you're referring to the gorilla effect (see Invisible Gorilla test)...
@@AT-SOI yes I am I suppose.
Another aspect that determines temperature is a planets atmosphere. Ie the comparison between Mercury and Venus. Mars is a very thin atmosphere but that was not the case in the past, it’s surface Is covered with evidence of water erosion, large bodies of water, the amount of erosion that seen on earth requires hundreds of millions of years. So at some point in the past Mars had an atmosphere and temperature capable for liquid water on its surface over a time period of between several hundred million to a couple billion years, it is more than enough time for complex life to form there, remember all complex Life on this started only kicked off around 550-600 million years ago!
Then you need to remember that planets are forever evolving, the earth today (its climate etc, even its atmospheric makeup) is not tje same as it was in the past. In fact if you were an alien craft flying past earth some 600 million years ago, our earth would’ve looked nothing like it does now, no green landmasses no blue oceans just a massive white ball completely covered in ice (much like Europa does today), If those aliens had the same requirements
For life as we do what do you think their impression of earth would’ve been? Over their life span planets in a change it’s just in our life span it’s much harder to grasp.
Scientists believe that mars was become more earth-like (today) a
Billion + years than earth did lol. Although we know much less about venus than we do Mars, venus was also a much more habitable planet than it is now in its past.
The two other close celestial object our moon and Ceres both shown evidence to have contained atmospheres capable of liquid water to form on their surfaces, ceres at some point in its past was an ocean world, completely blue.
Of course our universe is teeming with life. It's simple math. The question however is not where it is..
The question is when is it? Time is what separates all things in our perception. When did life develop/exist?
U are making a big assumption, its mathematically impossible for life to exist outside earth
If there's other life out there in the universe, it has no need to interact with us until we learn how to interact with ourselves.
The problem with part of the video and those like is the statement that the galaxy is so old so where is everyone. You don't take into account that advanced civilizations would require a second generation solar system in order for it to have the heavier elements needed for advanced science. It would be impossible to start an advanced civilization in a first generation solar system with Hydrogen, helium lithium and the like. Good luck with that.
The best thing about channels such as this is that it sparks conversations and the spread of knowledge.
I guess if a civilization becomes smart enough to travel the universe it may soon after realize it's safer to do so with stealth. Considering the limits of travel vs the vast distances there may be little to gain vs the potential risk of revealing your location.
Safer? Against what? A bunch of dead planets and microbial lifeforms?
Stealth is incredibly energy intensive to do, and is a complete waste against a bunch of bacteria and maybe a few lizards.
Webb will begin to give us more reliable numbers to plug into the Drake equation. That alone will be exciting.
As for civilizations surviving millions or billions of years - the odds are absolutely against it. Human civilizations have survived, at most, a few hundred years (here I am not talking about ALL of human civilization, but individual civilizations, such as empires - the Persians, the Incas, the Egyptians, etc).
Plus, any civilization will eventually encounter geologic and climate shifts (including changes in atmospheric and oceanic composition), and cosmic challenges such as changes in the local star(system) or impacts from other celestial bodies.
Very good point that we may not recognize advanced alien technology - for many reasons, a few of which are:
1. Other intelligent lifeforms may not look like us - they may not have 2 arms, two legs, big black eyes, and a bubbly big brained head like they are almost always depicted. What if they looked like a cloud of particles? Or a patch of tar?
2. The way we do space travel - with big, heavy, metallic, fossil fueled objects may not turn out, in the long run, to be a very good way to do it. I suspect our space rockets are pretty much analogous to the stage in which airplanes were built from wood and had fabric sewn on them, and were powered by what would be a moped engine by today's standards. There's absolutely no reason to expect that a space-travelling extraterrestrial's vehicle would look just like ours, only better - or even be made out of similar materials, or be controlled by what we would recognize as a computer. In fact, the way we imagine space travelling vehicles is entirely limited by our own past - a past which another space-travelling society would not share.
So yeah, it's entirely possible we're surrounded by them, but we just don't see them. Like the way an ant colony can be surrounded by a city of 20 million humans and not be aware of it.
We may not have evolved to the point where we can even see a civilization that has managed to persist millions of years.
To such a civilization, we would not register at all on a scale of intelligence.
Sometimes I wonder if the whole idea that humanity is intelligent at all isn't just more ignorant arrogance.
At the species level, I don't think we behave intelligently at all.
We're killing ourselves and destroying our ecosystem with our own waste products - and that is a problem that plagues even the most primitive bacteria that become over-successful.
We haven't solved the basic problem that causes species of bacteria to go extinct, yet we call ourselves "intelligent". What's with that?
A very thoughtful comment in class with Avi Loeb's.
Good points.
The distances are so vast and incomprehensible that communication between potential civilisations is impossible.
“Apply yourself to a multi-faceted existence, learn and connect to the multiverse the influence is quite powerful, profound and dominant’- Andrew Rogers.
The multiverse is a group of multiple universes. Together, these universes comprise everything that exists: the entirety of space, time, matter, energy, information, sentient beings, spirits, spirit guides, gods, goddess and aliens, and the physical laws and constants that describe them. The different universes within the multiverse are called "parallel universes", "other universes", "alternate universes", or "many worlds".
I already believe that we have been visited by Aliens since ancient times.
Our current level of technology is that of a very small row boat thinking that reaching the other stars is the same way.

@@colinc.8742 what was science fiction just a few years or decades ago is now reality. Just apply that to aliens and space travel
There is an argument that our universe is far too young, just a mere 13.8 billion years old, and our universe is expected to last way beyond googol years (10^100 years).
It may be that intelligent life is extremely rare.
So its entirely possible that we are the very first intelligent life, and all other intelligent life that will come to existence may only appear in the far far future.. and for them, we, Earthlings would be the Ancient aliens.
Most people: We can't possibly sail across the Ocean with a shallow draft boat...

The need for some humans to explore, to become famous even, sometimes pushes humankind to the brink; the edge of the precipice standing over a great abyss. And from that precipice, sometimes we find ourselves driven to even greater things. Just tell humans that it can't be done. And there is someone, right now, thinking of new ways to achieve the impossible.
2.41 “but it probably didn’t.” Brian Cox’s dismissal of the ancient alien hypothesis. Oh dear.
I'm very proud to say I have two tickets to Brian Cox lecture in Minneapolis in a few weeks. I have a room for two nights and my girlfriend and I will drive down and finally have a weekend alone while our daughters spend the weekend with a family member. We have not had anyone to really watch our children for us so for the past decade we have not had much time alone together. I'm a big physics nerd and she is a geek 🤣 🤣 🤣. We should both really enjoy this weekend
Wow, Brian... such an optimist. I disagree. If when the moment I die we still have not found life beyond Earth, then the answer to the question is yes, we are alone in the galaxy. It doesn't matter whether we make contact in a thousand years, for me within the timeframe of my consciousness, there is nothing beyond our planet. Nothing. Either we are the first or the vastness of time and space make it statistically impossible for two civilizations to ever meet. And the latter seems less and less likely as well since we also see no tell-tale signs of life anywhere at all. AT.ALL.
What if its discovered 1 day after your death? Science and technology is getting better and more accurate by the day so its more likely than ever that life will be found
Yes we are alone. Though there are animals of different species out there in the universe. When we begin to venture out into the universe then some humans are going to evolve to adapt to different environments. Some of us will also use science to change our DNA so we can live longer or to make us more adaptable to certain environments thus creating a new race/species.🖖
I'm guessing you're religious too right?
@@MrofficialC I'm not really religious, there are too many inconsistencies in religion. Because all facts are not presented I will not throw away the thought that there might be a God. A "time machine" can prove if there is such an entity as a God.
@@MrofficialC by the way theories of the existence of highly advanced alien civilizations is still a myth/wishful thinking unless we can prove of its existence with facts then there is no basis for anyone to argue of its existence.

Milky Way galaxy contains very very huge amount of star and planets that it can be possible that Extraterrestrial life forms exist. If we are alone then I don’t see the point why our galaxy has to be very enormous and why is there more galaxies than once.
@@scamhunter2346 I never said that there is no life out there in the universe. However I don't think there are intelligent lifeforms like us or more advanced than us out there. Not because there are other stars/suns out there in our galaxy one has to believe there are other intelligent lifeforms out there. It is more likely that we have to be the ones to create the environment for lifestalk and trees to survive. We already have the blue print on how things are supposed to be from earth's position in solar system. Another thing mars is a perfect example of a planet that should have had life but something went wrong. Now we are on the verge of finding ways to get to mars and start terraforming. Believe it or not we will have to do that thousands or millions of times to colonize the known universe. This is why we the America's and Europe should start sharing more technology so the great minds in other countries especially Sub-Saharan Africa and Caribbean can give their contributions in this development. Education health care and financing must be given to those countries so mankind's technology can increase at double or triple the pace.
Maybe we'll never know. The only three ways we could know is either we travel to them, they come to us, or they broadcast their media or message through our equipment. some say there is no good reason to wonder about other life outside our atmosphere. But the brilliance in the curiosity is that we are potentially preparing ourselves from the unknown. Maybe there's one or four hostile alien lifeforms around our galaxy or even hiding inside our beloved milkyway.
It’s self indulgence to believe we’re the only ones in the Galaxy. There’s millions of species on this planet alone!
Once we get the right equipment into place I think we will find plenty of signs of life... even some intelligent life. However, I highly doubt we will see that much life traveling through space to other solar systems, etc. At best, each one might inhabit one or two extra solar systems to ensure the survival of their species. Any more than that just doesn't make sense and could even work against that goal.
Thats a pretty reasonable thinking, for the most it's plausible. Also, that which does and which "doesn't make sense" is kinda biased and based on our human understanding and limits, but yes, it would be more plausible to use likes of AI driven mechanical drones (Von Neumann probes) for space exploration, mining etc.. After all, we are the species who at this very moment have "rudimentary" drones operating on surface of the other planet.
Most people have no comprehension of the absolutely masssive distances even to the closest sun to us
@@oldman2800 Exactly. And unless you have some kind of FTL travel and communication then you basically have no meaningful connection to each other. Even sharing research data would have limited benefits since everything would often be years out of date. And trade of physical goods would be pretty non existent. I mean, you would have to have some kind of insanely rare resource to justify shipping something across light years of distance.
@m_train1 I'm not so sure that is true. If there is other life out there than a massive expansion is going to look like a major threat to them. And if there is no other life out there then you doing a massive expansion basically creates that very scenario.
Now, if you have FTL travel/communication then you can avoid that. Otherwise, you are talking HUGE time scales with lots of isolation. Even if you assume nothing happens that results in them forgetting their origin they are bound to start thinking of themselves as a completely different entity and see others as a threat. Heck, if you go out far enough you could be talking a billion year time difference... you may very easily be a completely different evolved species by then.
That said, I agree you would want at least a few surrounding systems colonized for the purpose you suggest.
The JWT is the right equipment you are looking for. I personally don’t believe that any life will be discovered.
There’s 100% other extraterrestrial life outside earth, there are hundreds of thousands of separate galaxies and each has many planets within. There’s absolutely no chance we are alone, we are just too far to find them.
actually, there are 2 trillion galaxies that we know of in our observable universe.
Maybe aliens communicating with us is the equivalent of us talking to a leaf. So they simply don't bother.
What's scary is that we are alone in the universe, what's even more scary, is that we are not and we will know this, but never be able to communicate with that life.
Neither condition should scare any one of reason.
Why do we presume that "alien life' requires a solar system and atmosphere "like our own"?
Isn't it likely, and possible, that "alien life" is more alien than us and has different requirements to sustain "their life"?
Like a giant turtle floating in space?
Variations outside of our own experience are certainly possible. But physics, processes, and the basic building blocks of the material world are the same everywhere, so looking for familiar conditions makes sense.

For complex intelligent life, you need a massive number of very unlikely co-incidences all coming together. Earth IS special. Take care of it.
Is there sentient life on other planets in the galaxy ? In my belief yes there is yet they are so far away for us to know what kind of life forms that may inhabit them or how far that they may have advanced or if they are not very advanced . Some of the planets inhabitants may be as primitive as what it was like in the history of our planet and with other new and younger planets life may just be starting . So thinking that our planet is the only one to support life is totally wrong .
No there is none! Its just sci-fi wake up!
Nobody is stating that Earth is the only planet supporting life. That would be an unwise statement that cannot be supported by evidence.
By the same token, it would be equally wrong-headed to state that there is definitely other life too. We can guess and have our beliefs, but the truth is that we don't know, and probably never will.
Hard to believe we would be. Infinite universe and all.
life is not just chemistry, and I am surprised someone of Brian Cox intelligence would make such a claim
If life is not just chemistry then what is life?
Brian Cox's voice is great asmr.
If there is intelligent life out there is one of 3 things behind us in development the same level as us or so far ahead of us it’s unreal, I just wish I was around to see us become a space fairing race we don’t do enough to be getting out there and exploring
The Drake Equation might as well be the Drake Guess. How do you equate something when you're missing ALL of the mathematical variables? You can't do it.
Especially if any of the factors is zero, the result is zero.
I think we have had science for much longer than 500 years!
The trouble is there is no route from chemistry to biology.. There is no known science which produces life from simple chemicals. Dr. Cox thinks there is a way, however it's only faith which brings him to that conclusion. Dr. Cox is an adherent of the religion called Scientism.
