      Technically, you cannot answer that question, only the person you are addressing can do that.
      Also, if the universe is infinite, which it almost certainly is, then the emergence of life in an infinite number of places becomes (by extension) an absolute certainty.

      Very good video! I agree that we cannot currently know. I guess and speculate, and I think we can look at the ribosome as a key here. A very basic proto-ribosome could have formed in two ways, with protein first or RNA first. Also a mechanism of inheritance could have formed either way first too. As long as at least one can occur easily enough abiotically, and give rise to the other (these are the things we don't know, except knowing RNA can probably form proteins on its own in a purely-RNA proto-ribosome and that proteins can certainly form RNA). If and only if it requires both to be simultaneously initiated, and that that is unlikely even in a vast ocean of hot chemical soup, then life could be much rarer. The problem I see is that although we can "initiate" some very basic form of chemical self-replicator via RNA or proteins (proteins being more likely to be capable of replication especially in a bath of amino acids), for actual viable life beyond just random chemistry we require RNA, proteins and lipids to come together in a special way. That might IMO be the hardest step.
      Despite that, I think that life can form relatively "easily" enough to be common. With lipids self-aggregating into capsules easily, amino acids being common in the universe and nucleic acids at least being present (haven't we detected evidence for that? Not sure) or being able to be naturally formed catalysed by volcanism or similar in a chemical soup, then life should be common. The problem i see is if amino acids and/or nucleic acids won't randomly polymerise enough abiotically. That woukd be a big problem.
      RNA is what really needs to form for life to begin IMO (I am no expert! And have little evidence). RNA can both code information like its stable cousin DNA can, but it can also fold into complex shapes and thus perform as a controlled repeatable catalyst for chemical reactions - like proteins. It can then form structures to replicate itself, and that is all that is needed (though it needs to happen 'en masse') for Darwinian evolution to begin. It can then later start catalysing the polymerisation of amino acids into proteins, and then those proteins can later start catalysing the copying of RNA into DNA. RNA is very much a poorer version of proteins and DNA.
      But we look at life from a very DNA-oriented perspective. I studied mechanisms in yeast by which proteins themselves carry inheritance and participate in evolution - unique prion-like proteins that can do some special things similar to RNA. This appears rare in nature, but it exists and happens. What if proteins like these (which are capable of converting other similar proteins into copies of themselves and aggregating into complexes, which can do stuff such as catalysing reactions) came first, and quickly gained the ability to produce RNA. We lost most of these Darwinian proteins over the aeons as they would be very poor in comparison to RNA, the RNA life they could have created would quickly overtake them. If amino acids, but not nucleic acids, are present in abiotic conditions throughout the universe, and polymerisation of amino acids can occur via common but abiotic means, then this protein-first start to life could be far more feasible than RNA first and solve the problem of either naturally-occuring nucleic acids or natural mechanisms to polymerise them, needed to form sufficiently long chains of RNA, being very rare or unlikely to be produced randomly. Excuse that awfully written sentence.

      Depends who you ask, once we agree that a miss is the best on the planet, it's safe to say that she's the prettiest in 'our' universe since beauty is in the eye of the human beholder. I'm sure every alien being that has beauty contests feels the same way as it's very difficult to think of a sexier lifeform than the ones that have evolved attributes to make us want to reproduce with them. We could never truly judge an unbiased interplanetary miss universe unless we judged our local lifeforms and then asked God to pick the winner...I think God is smart enough to not tell any single female lifeform that she is prettier than the other finalists. 🤪🤣🙏

      It was more of a commentary on the idea that if there’s only 7 billion intelligent beings currently alive in this universe, we’re even more rare and precious. If that were so, it makes it extremely sad. To us, 7 billion sounds like a lot, but on a universal scale, it’s almost nothing.

      Yep. It would mean life is extremely delicate. We could ultimately be the reason life ends in the entire universe lol.
      But I dont believe we're alone in the universe. Just because we dont see it doesnt mean it's not there. We dont even know that life doesnt exist in our own solar system (outside Earth, I mean). We dont know that at some point in the past that life didnt exist elsewhere in the Solar System. To find evidence of life, we'd have to be looking in the exact right place at the exact right time. I also doubt that intelligent life would be so careless as to shoot radio signals off into the universe like we do. History has shown that lifeforms finding other lifeforms when they migrate doesnt fair well for the less advanced lifeforms. Native Americans are prime examples of that.

    Man... as a 29 year old that's been walking a pretty lame existence for the past 8 years, this brought me to tears at the end. I spend so much time hating my life and hoping that something brings an end to it because I don't have the bottle to do it myself, but the ending of this video just brought me out of that temporarily, to the point that I had tears streaming down my face. If we're truly all there is, there's not a single monetary value you could place on what we're going through. If you could sell your "existence" (the existence which I hate so much a lot of the time, that I complain about, and feel excited to be over with) there is not an amount high enough that would put a fair value on it. If we're truly alone, it's the most valuable thing in the entire universe. I guess I mean, if there were ever electronic-non-physical beings that knew we existed, and could some how buy our existence to try it for themselves, to see how it truly feels to walk on a planet in a real human body, there is no amount that could buy it.

      @PowerMixxes 5 років тому +7

      To be honest there almost no chance we are alone, the argument that we are lucky that we survived through so many disastrous events only points towards that its not that hard for life to evolve! If you look at thousands of different species that live today on our planet and someone tells you that 99% of species that were alive on planet earth are extinct I would think that its impossible (if planet earth itself wont collapse) for living organism to go extinct! So being able to survive through 5 mass extinctions seems to point out to that its nearly impossible to go extinct once life started! Also if from simple bacteria evolved millions of animal, fish species then it seems in the Universe should be the same, from star dust there must evolve life and it must evolve everywhere! So it seems based on evolution on earth and based on how hard for living organism to die out and how easy through time for it to multiply and evolve (from small rat mammal to lions, monkeys, humans, zebras, elephants, giraffes....), Life in the Universe should and it did (from big bang to stars to galaxies to planets to life) to evolve in big abundance and variety!

      Emerging scientific data in the journals agrees that life is rare. The increasing habitable zones means that less then 1% of the planets in each galaxy being unsuitable for life.
      Known Current Habitable zones as of 2017:
      - Water habitable zone
      - Ultraviolet/Radiation habitable zone
      - Photosynthetic habitable zone
      - Ozone habitable zone
      - Planetary rotation rate habitable zone
      - Planetary obliquity habitable zone
      - Tidal habitable zone
      - Astrosphere habitable zone
      - Electric wind habitable zone

      For host stars with an effective temperature more than 7,100 K (7,100 °C above absolute zero) or less than 4,600 K, even for just microbes, a team of four Chinese astronomers showed that the liquid water and ultraviolet habitable zones will not overlap. This may seem like a fairly wide effective temperature range, but it is narrow enough to eliminate all but 3 percent of the Milky Way Galaxy’s stars.

      Japanese astronomers Midori Oishi and Hideyuki Kamaya established that the zone of overlap is even narrower including the metallicity requirements of the Host star, this leaves less than 1 percent of our galaxy stars as candidates for bacterial life. Advanced life has even more stringent requirements.

      My best guess is it is somewhere between the "crowded universe" and us being totally alone. It's extremely rare, but not so rare that we are literally the only ones. And the universe is also very big, the raw amount of empty space is much greater than the number of potential words. If other civilisations are so far away from us that we will never come into contact with them or find evidence of them, we might as well be alone. The most boring and realistic answer to this question is probably "it doesn't matter because we will never encounter it either way".

      @@jrpipik did you not watch the video? The immense time and space is irrelevant. That is the whole point. Yes, that experiment tells us nothing, but no experiment ever conducted gives us any idea how rare life is. Your assumption on more locks being picked if you give them billions of years ignores the possibility that the difficulty of picking the lock could be scaled up billions of times(thus the probability would be the same). It is simply an incomplete equation. We cannot comprehend how immense the universe is(infinite?), could it be that we cannot comprehend how rare intelligent life is? (infinitely rare?). Believing there has to be life elsewhere is no different than believing there has to be a God.

      Do not propose that "I don't know" is a valid answer about the mystery of life to any religious person. Such people go to a lot of trouble persuading themselves that they do know, and rely on constant affirmation from fellow believers. Faith is the capacity to believe something that is not true but must be true because it supports a person's world view. And that is why religious people put so much emphasis on having faith. If something was obviously true -- for instance, that we are born and eventually die -- not a shred of faith would be required to believe it. On the other hand, believing there is life after death requires a huge amount of faith -- often backed up by some hefty tome of dogma describing supernatural beings who create us in their image, or similar nonsense.

    Fascinating talk. It's refereshing to hear the subject of one of humanity's most compelling questions being discussed so rationally and so intellectually. Whatever the answer, it does indeed have profound implications for our species. I just hope we do find the answer some day, though I'm not certain we ever will, and that prospect is somewhat depressing. But that's exactly why we must keep looking. Our pursuit of the answer may yet also reveal the answer to that other compelling question humanity has been asking itself since we first gazed up at the stars..."Why am I here?"

      I mean, we've created amino acids in an early Earth environment, and like the narrator said "maybe we haven't run these experiments long enough" (especially when the Earth is 4 BILLION years old) is a very likely scenario.

    Imagine the billions of years of evolution and it took us humans less than 2000 years to be technologically advanced. We became intelligent and curious of other intelligent lifeforms AFTER billions of years of evolution. So my point is, I think every habitable planet has their own specific evolution timer of its lifeforms. As an example, maybe our closest habitable planet currently has lifeforms that is equivalent to 500 million years ago on Earth. So we don't see intelligent lifeforms now since they're in their prehistoric period. Maybe we'll go extinct 50,000 years later and 500 million years later, those lifeforms are celebrating their first space flight to their moon and wondering if they are alone. In conclusion, the odds of two intelligent lifeforms being within close proximity and within the same narrow evolution window is astronomically low.

      Though that's not always the case. We now know that certain things close to us really ARE rare, unique or special.
      For instance, humanity itself is a unique mammal. Not only our intelligence, but other factors, eg bipedalism, our running endurance, our dextrous hands, our capacity to sweat, our long growth phase.
      Our sun, too is quite rare. It is a G-type yellow dwarf star, not very common compared to the vast majority of stars, which are M-type (red dwarfs) or K-type (orange dwarfs).
      And even among G-type stars, our sun is still unusual. It is unusually bright and hot for its mass compared to other G stars.
      Our moon, too, is unusual. For one, no other moon in the solar system formed the way it did. Our moon is also the largest proportionally to its planet, of any planet in the solar system, and plays a big role in stabilising Earth's orbit. This is again, very rare for planets anywhere.
      TLDR; the factors that make Earth, Earth, and us, us, are very rare in the universe, and are anything but ordinary. Many times, new discoveries have violated the Copernican principle and challenged our assumptions of mediocrity.

I of course accept that universals can only be imaginary(or perhaps just supposed). I wonder if the bricks in a wall can sensibly suppose themselves to be the wall(or perhaps even the building of which the wall may be a part There are so many -or as many as there ae men(human beings/dreaming machines) of life, and I note that you creatures suppose yourselves yo be what you call "intelligent"(not of course, being dreaming machines) having the slightest idea what intelligence may be) Of course the bricks that constitute the parts of a building can have no idea of the building are the pieces of a jigsaw puzzle have any idea of the puzzle of which they are parts or any idea at all of jigsaw puzzle in which hey have a role or position being no more than painted pieces of card or board, or some sort of ceramic if bricks and without at least *some*some* idea of of what they are parts or pieces they can have very little-if any, idea, of what they are parts and or where they belong, if they belong at all, and of course the very idea that there is a building puzzle or greater whole can only be fanciful to put it at its most charitable.
      It is surely axiomatic that the fragments of a whole can know nothing or are not able to *know*being no more that fragments of some*Un*_known

      @@scottslotterbeck3796 This explanation is predicated on two very weighty assumptions: firstly, that the physical distribution of life across the universe is even, and secondly, that our perspective of the outside universe from the vantage point of Earth is not skewed by the correlation of distance and time.
      For example, if indeed life has developed concurrently across great distances, it would be impossible for each respective sentient species (if they are sentient to begin with) to observe one another given the vast amount of time that each would have to survive in order to do so. Even if sentient life developed elsewhere in our own galaxy tens of millions of years ago and developed to the point where there would actually be technological or biological markers to indicate its presence, the probability of us observing it at that precise window of time decreases with distance, as beyond a certain threshold we are observing a time before such a species existed.
      Even more challenging is the belief that a species older than this (say, one that appeared hundreds of millions of years ago) could sustain itself for a duration long enough for us to observe it; our own species' limited longevity and challenges with finite resource capacity so far have not borne out the conclusion that this is even possible. By the time we peer in its direction, the civilization could have long ceased to exist and we would have no indication of its former presence.
      Overall, the likelihood that our limited technologies which have existed for an incredibly short period of time are sufficient to pinpoint life that is widely distributed over distance and time seems very low. Life could be a relatively common occurrence in the universe, but our inability to observe it from our narrow vantage point may be a limitation we will never overcome. Thus discounting the possibilty of life existing elsewhere because we have no evidence of it seems as foolhardy as claiming we will eventually find evidence for life - we may simply never know.

    This is one of the rare "we-are-alone" videos on youtube where the comments are civil and thoughtful, suggesting Professor Kipping did a great job communicating this unpopular view and gently undermining the defective intuitions of people such as Bill Nye and Neil DeGrasse Tyson. He takes an elegiac tone towards the conclusion he's driven to however, which I don't agree with. Since I always doubted the existence of aliens, I am emotionally neutral to the prospect that we may well be the only intelligent beings in the universe. Of course I believe we should continue looking and refining our instruments and so on, but we should also be contemplating the desires and anxieties that make us cling so desperately to the hope that life must exist elsewhere.

      @@SKBottom Does our loneliness take precedence over the truth? We have been looking out at the cosmos for centuries now, and it seems fairly obvious that there are no large sectors of the universe that are artificially altered in a way that might indicate the existence of alien super-civilizations. Such evidence, if it existed, would be the most exciting and loneliness-busting discovery of all, but it does not exist (of course we must keep looking). Anything short of that does not do much to alleviate loneliness (say the detection of pond-scum on some remote planet where the vast distance along with cognitive and technological disparities pose unsurpassable barriers to communication and interaction). Robin Hanson's recent paper on "grabby aliens" concludes that humans are early arrivals in the development of the universe.

      I hear you. People can be edgelords about this subject, but it doesn't take a philosopher to recognize there's a profound, existential component to this idea. Especially when you consider that the human race is less likely to survive as long as people often imagine, in science fiction. There may not be an inhabitable world within reach, and the less inhabitable ones like Mars may not be practical. We might have a few thousand years left, and after that, sentience leaves the universe. Maybe it'll return, maybe it won't. We might be living in the only little sliver of time that the universe had life, had consciousness.
