Your video contradicts literally thousands of hours of televised research I've done on this subject, which suggests not only a galaxy abundant with life, but one in which nearly every alien species has adopted the English language as their preferred mode of communication. Live long and prosper.
Astronomy mixed with existential philosophy coupled with a voice rivaling that of Morgan Freeman in its way of penetrating to the soul. I cannot thank you enough for your work and effort.
I've dedicated my regular guy life to education for 40 plus years. You, my friend, capture my imagination and grasp of reality like nobody could...ever. You are without a doubt the most brilliant mind i have encountered in my existence. Thank you for your hard work and efforts in words and observations of our world.
brodefineportraiture Yes-I agree. I have been obsessed with his presentations, both for their brilliant content and his entrancing delivery. What a pleasure in these spiritually cruel times.
@Nbsthj Near? It's a large universe. Consider him, yourself, (or Musk) equal, but coming from a different point of view. All good. No man is an island.
Maybe we are the first in the universe. Maybe the universe is ours to subjugate. Instead of living on one planet complaining about equally, all like minded people can have their own solar system.
@@allisbeneathme3350 yeah but just as the first Americans came like minded and today we have so much diversity so would those solar systems. But i imagine futer explorers will start there own planets and those planets will end up having wars and different skin color and all these differences we have here today. Have a great day and let the universe bless you
Event Horizon JMG, your videos also tend to keep my ongoing existential crisis front and center in my conscience!..propelling it straight towards the cold, dark, lifeless vacuum that our universe will become..GOODNIGHT!
Dear Cool Words team. Your video is a perfect example of an ideal video of science dissemination. To describe it,l some would say that it is pure science, although that is not enough, as it is only analytical in its content; others would call it poetry, perhaps even, a masterpiece. However, I would rather prefer to use the term philosophy in its truest sense; a beautiful homage to the thirst, passion, and veritable love of knowledge. Thank you very much.
I MISS that guy something 😕 😪 fierce 😢. At least, in its day, Cosmos was SUCH an excellent series 👏. I NEVER missed an episode. Cosmos and Contact were 2 of my inspirations for studying Electrical Engineering. Thank you Mr. Sagan.
Other than the comedy of him saying you'd have to survey 'dozens' of worlds to find life. More like a near infinity of worlds, for all intents and purposes.
Prof David Kipping is amazing as a scientist and as a thought-provoking and artistic science presenter. I always relish his way of presenting scientific thought, ideas and speculations. Carry on Professor Kipping!
Mind blown. Once again. Thanks for another great video, David! The more I think about it, the more life, consciousness and intelligence seem far-fetched. I mean, were we unbiased, immaterial observers of the universe, how could one possibly imagine such an incredible reality like the one we live in today. Even the most extreme astronomical events, although grandiose, pale in comparison to the unbelievable complexity of life on earth, to say nothing about the human mind. You are right to say that our existence is a precious gift, and we should make the most of it. Thanks for helping us put things in perspective! - Patrick Fulop
This video just nails it imo. I've always thought this to be the most likely answer to the Fermi Paradox. We might be alone in the galaxy.. At this moment! Don't just think vast distances, but also vast timescales.
I once read somewhere that some astronomer or physicist compared intelligent life to small lights on a Christmas tree. With the tree being the galaxy, and the lights being potential intelligent life. When speeding up time a gazillion times, the tree looks like a disco ball, with lights turning on and off everywhere all the time. But in reality, at any one point in time you'd see not a single, one, or mostly a couple lights on simultaneously. Can't remember where I read that though, but I've always remembered it.
@@MacSvensson I remember what your talking about. It was on PBS channel 13 over 20 years ago and the guy started out with a table full of trimmings for dinner waiting for a lobster to arrive from the ocean and the point was just because the lobster didn't show up didn't mean they didn't exist and then he went on with the Christmas tree lights and I guess it was the drake equation projected on to the xmas tree and the different calculations started to dwindle. Yeah I remember watching that. Your not alone..... get it lol
What a delight to discover this channel! You bring such a philosophical, poetic, and distinctly human touch to the exploration of space and the universe.
This made me extremely emotional. Not often does science or galactic concepts like this bring me to tears, but when they do, it's intense. This was amazing, and VERY intense!💜
Depressing? In a way, yes! I won't live long enough to get to see enough of it. Or, that I was born too damn early. 😟☹😪😭. That i won't get to understand, or experience enough of it...etc etc ☹. Depressing indeed. I'm SOOO small 😭. WE are so small...far less than a blink in time. Merely a few more atoms in the vastness of the universe. 😢 Are we going to make it?
Inverse square law says that this is basically impossible. They'd have to live close enough to us to pick up that signal that we would be able to observe the effects of their existence on their host planet. If a radio signal is powerful enough to make it to them, then their visible light is bright enough to make it to us. If they don't receive stellar energy to heat their planet enough for biological life to form, then they would require internal heating mechanisms to provide that heat, and then we'd be able to observe that planet in the infrared spectrum instead. Sorry to say, we are almost definitely alone and probably always will be.
Funny thing is, it probably isn't the tv signals that will give us away if life beyond Earth does actually exist. Do you have any idea at all just how bright a nuclear explosion is? And do you have any idea how many atmospheric detonations of nuclear weapons have occured in mankind's history? It's a LOT. One of those bombs, Tsar Bomba, was so powerful that the shockwave it generated was still detectable without scientific instrumentation on it's 3rd passage around the globe. As in, you could feel the Earth react beneath your feet to this blast from the other side of the planet on it's third go around. There is NO WAY WHATSOEVER that at least one of these nuclear blasts didn't attract the attention of any astronomy-studying sentient aliens if they're even remotely nearby. These blasts would have highlighted our planet on multiple occasions. I wouldn't be surprised if our usage of nuclear weaponry was both our announcement of our existence, and the act that condemned us to solitary isolation even if other sentient life-forms do exist out there.
I lack the ability to adequately articulate how much I love these videos. Carl Sagan has been important to me my entire life, and the wonder he instilled in me, persists to this day. I look up at the night sky, because he first showed me its beauty.
Cordatus Scire Cordatus, you just demonstrated your powers of articulation. Thank you-and I agree with you regarding these incredible visual, aural essays.
My fascination with what lies out there is what pushed me to study, the sheer amount of possibilities, the idea that nothing is impossible, but improbable, just becuase we haven't observed life as we know it, doesn't mean that there could be interdimensional beings, of even corporeal life for that matter.
Carl Sagan was both a physicist and a poet, perfect mix to show the world how humbling the universe is. David Kipping is a physicist that shares the same feelings we all have at huma level.
Reminds me of the book The Alchemist, when the boy gets sent out on the dessert to survive and he finds a snake because if there is life there is water. Life begets life.
A P.h.d. is a doctorate if I'm not mistaken. So he would in fact be a Doctor. If I am perhaps wrong, he none the less deserves the title. Hell always be a Dr. to me. Lol.
I wish with all my heart that your videos become "trending" on youtube. These are the videos everyone needs to watch, not makeup tutorials or silly drama between irrelevant youtubers.
Humanity has gone from thinking ourselves to be special, like the belief we are in the image of God, to science and rationalism showing we aren't so special we are one species on one little planet. If we are indeed alone than we are special. There's something poetic about that.
We are special unique made in Gods image! I believe this is the only planet with life..if there is life elsewhere then god hasnt told us, not important for us to know, we gotta get right here, on this planet!!!
@@iamBlackGambit _Which_ god? The ancient Canaanite land god of Israel and Judah, turned the one and only god in the Abrahamic faiths? Countless versions of countless gods have been claimed and countless more have been completely lost to time.
It is a child-like and deeply moving compulsion of ours to want to make sense of it all, and then so desperately to wish we could show someone what we have done. As if we look for someone just to mark our homework, correct our mistakes and maybe give us a kind green tick, if only for effort.
20 years is nothing, we are too impatient, too inexperienced yet to make more the a guess, it’s decades, maybe hundreds of years before we can say we’ve answered the question. We should stop this discussion and just keep looking, without heaving the feeling we are owed an answer.
Every time I listen to this, my own wistful, half-sad suspicion is verified-we are very likely alone. Certainly David bolsters my persistent doubts that anyone waits for our phone call somewhere in the Milky Way, or even in the Observable Universe, as another sentient, volitional, technologic civilization that has not yet obliterated itself or its home planet. All the more reason, then, to treat each other as fellow volitional sentients-with magnanimity, humility, kindness and shared exhilaration.
I just want to thank you for making these amazing videos. It rarely happens that I can watch something for half an hour and not get bored a bit. I get completely immersed in your videos. Keep it up David!
When i was a kid i picked up a broken balloon in a field with a string on it. A message was attached to the string. The message came from a church in Detriot . The message was something about how far God's will travel. i lived in london Ontario Canada at the time. And was going to write the sender back but i lost the sender's address and church name. This was in the 1960's.
As long as we know who he was, what he has done and identify him by his voice, he will not be forgotten. We are all temporary, what matters is what we leave behind.
Zeromancer I’ll never forget Sagan’s poetic description of the beginning of the end of Earth as a home for viable life - “And one, last, perfect day . . .”
@Arachnicution I am actually a very humble person, but not versus people who already have inflated ego's themselves along with a false viewpoint. Also i don't 'attempt' to sound intelligent, person who doesn't know me at all, i am intelligent hence i sound intelligent. So don't 'attempt' to downplay my character without having full knowledge of it. It is what it is *shrugs*
It's so good to hear other people thinking and communicating deeply. The mind is a restless place that never seems to be silent. This channel is really great! Also maybe we are alone in our galaxy but if you expand the search into the entire universe then the chances of finding life go up infinitely!
I used to have a hypothesis that each galaxy was only capable of supporting one civilisation at a time. Mainly because of the fact that large parts of the galaxy are pretty inhospitable what with, supernovas, gamma ray bursts and so on. Man, I wish I could talk about this stuff with my friends, most of them just glaze over if I try and engage them with this type of discussion.
Ikr, Although I actually think our galaxy should be large enough for quite a few civilisations, space is large and actually there isn't a real need to colonize planets, of course it would be nice, but O'niel cylinders are definitely a good option too. Our galaxy is 100.000 light years across, has billions of stars, yeah most of them are in less hospitable places, but life could've originated from somewhere else, but used technology to conquer those challenges. But this all assumes that some type of Warpdrive is feasible, if it isn't then large interstellar empires are a bust anyways.
I love this presentation, I never get tired learning by lestining about this topic, is us our story from the star dust back up to take our place among the stars,I read and lestin this kind of presentation topic.I spend 6-8-12 hrs a day 7 days a week I am 72 yrs old and I have all my time spending this educational matter that the school don´t teach us.Is amazing leason also is a gift that enternet is been created for us to be consciously awaken our spiritual soul and understand we are at the infinite spiritual soul journey.
IMO, the abiogenesis of life on earth was a gigantic cosmic accident. Or it was so improbable that the abiogenesis of life happened, when life was never supposed to exist, so to speak. And I don't buy the numbers game.. just because there are trillions of galaxies, stars, planets does not mean life is common or extremely rare. Once we understand (if humans ever do) how life on earth began..it will emphatically suggest that life was a freak cosmic accident. As such, life on earth is supremely precious and special that we need to completely change the way we live so that the destruction of life (caused by humans) will cease completely. We need to protect the only known environment capable of supporting and sustaining life. Alas, vast majority of people simply do not care.. which is a tragedy for all species that Earth harbors.
Exactly. The chemistry needed for abiogenesis may be universal, but the exact conditions that such chemistry needs to occur in to create life certainly are not.
The point that it started soon after the formation of the earth could mean life is ubiquitous. If we think of matter as having a natural propensity to organise itself, then abiogenesis follows. Intelligent life is another matter though. Why did it take so long to wait for us?
I like your sentiment, but even if (intelligent) live is abundant I would still argue we need to save humanity. (But not as the plague we are now) and even at a local level, distances might be so overwhelming we might as well be alone.
There does not seem to be enough intelligent life on earth to coordinate a global thought process & to both preserve our habitat & ensure our survival beyond, perhaps, 2100.
You sound like a catholic priest talking to Copernicus, arguing why the earth is special (I actually agree with your opinion though, just a fun comparison)
Star Trek's next generation episode "The Inner Light" comes to mind a message in a bottle. I recommend that we do the same as in this episode so when we go extinct as a result of asteroid or nuclear war. A future civilization can learn from our mistakes.
What a time it has been; look at that view. If only there was someone to share it, discuss it. Are we just moping about without a lover as we kick pebbles with our boots. Do we need to accept something or embrace something? Expectation only leads to disappointment but yet we yearn to be not alone.
The poetry of Dr. Kipping moves the soul. He could be right or wrong about these far-flung assumptions, yet, does it really matter? The main focus and value of it is that it sets the responsibility of preserving life and knowledge beyond our time, and also high marks the extremely valuable gift that it represents. ¿Are we alone? ¿Are we surrounded by like-minded beings staring at each other in silence through the voids of time and space? Only time will tell, yet before and beyond that, it is our duty to preserve the precious spark we represent, today.
I find it unlikely if a lifeform evolved elsewhere it would reassemble anything like what we have here. Even small environmental changes would drastically effect life there. One of the major premises for this video right from the start is that people are social creatures. If for example we evolved on a planet with less competition we wouldn't have needed to work together and likely wouldn't have turned out to be so social. There could be a highly intelligent species out there right now that simply has no interest in communicating with us, at a genetic level. Or anyone else for that matter. We are also colonizers, we crossed the ocean without knowing what we'd find, we map and search every inch of the planet, we went to the Moon just to prove that we could. Not every lifeform would necessarily have this desire to reach for the stars. There could be a lifeform out there right now that spends almost it's entire life in hibernation and only wakes up occasionally to eat while still being a thousand times more intelligent than we are. There might be a lifeform out there that kill each other on sight and spend their lives in hiding and reproduces a-sexually with a negative desire to communicate with others. The possibilities are endless. Looking for intelligent life with the technology and desire to communicate is already making an incredible number of assumptions about that lifeform. But then include their desire to communicate not just among themselves but with other foreign lifeforms as well... This is already an incredibly specific lifeform with highly specific behaviours and highly specific desires we are looking for. At this point we aren't looking for aliens, we are looking for more of ourselves.
“.....for the moment the Earth is where we make our stand.” Its so hard for us to appreciate the incredible oasis of seeming perfection, that we live on. Great content. Your writing and delivery is almost poetic.
Better than a year later, and David Kipping is still on point and as interesting as when the video was originally published. These videos don't always say what I want to hear. They let me hear what we to this point truly know. Thanks Cool Worlds.
My thought at the beginning of this video was of David Brin's short story, "The Crystal Spheres". (note: started to describe why, but it's really a wonderful story, and don't want to give anything away to anyone who wants to check it out, so no spoilers). His intent was to provide a novel explanation of the Fermi Paradox. It has some science fiction and even fantastical elements, not just pure science -- but the sentiments here are (in part) the same, I think -- in both the loneliness and the majesty. A second echo that I heard was from a Star Trek episode, "The Inner Light" I think it was called, with a doomed race deciding to leave a piece of themselves, in a novel but deep way. Probably the most beautiful episode in the series, IMO. And a third one (this is turning into a "recommended reading list"!): Olaf Stapledon's "Last and First Men". No message left, in any direct physical sense, but there's a strong theme of a story being told through history, and that story endures in its own subtle way. It's from nearly a century ago, so the language strikes some as a bit stilted (he was British, too ;), and male-centric, but it is does implicitly address the question of finding meaning, and facing the end without fear and regret.
My favorite temporal comunication in Science Fiction was from Picard season 1. An ancient and powerful intelligence had moved 8 suns into perfect orbits which can't occur in naturally (according to this fiction). Loved this video. It's my favorite Cool Wolds video (so far)
The messages to future civilizations reminds me so much of the Prothean beacons and the blueprint of the Crucible in the Mass Effect Trilogy. Every civilization added something to it in their cycle...Let's just hope that the Reapers don't exist >_> Wonderful video, love your channel
The peculiar irony of being "self aware" is that we find it jarring to imagine that we are the only ones who possess intelligent consciousness. But of course, it would seem discomfiting. That perhaps, is the burden of being conscious.
This guy's voice reminds me of kurzkazagct. Soft and soothing, gentle and hypnotic. Very enjoyable and easy to listen to for hours. Heck I get ready for work listening to these videos.
I wonder if there would be passive "techno signatures" that would linger to be found after an alien civ is gone, the way that in biology today we see DNA as a kind of "signature" left from some long gone RNA-only/precursors.
When all is said and done, life seems to have emerged on Earth only once, even though we seem to regard this as quite a hospitable planet, with plenty of energy, carbon, materials, and water. My sense is that life may indeed be exceptionally rare, even infinitesimally rare.
There is a proverb in Persian: "Don't play with the tails of a sleeping lion." We seem to be doing that for the few decades. When the lion wakes up, we won't be able to put him back to sleep anymore.
BILLy GOAT GATES TO HELL peoples... Think.. Look up what Robert F Kennedy was breifed on Vaccine ingredient for this in an interview.. Used the 5 month old babies still beating hearts. It's true dark magick witchcraft.. Think!.. WAKE THE WORLD UP!
How about that: Humanity tries to figure out what the universe is and how it works since, who knows, maybe since 2000 years in a somewhat structured manner. Since 100 years we tried really hard with tons of different approaches. During the 2000 years, our picture of what the universe is changed multiple times in quite dramatic ways. Now imagine how limited our senses are, how confined our thinking. Is it too far fetched to conclude that in our efforts to understand something that is unimaginable older and bigger than we are, we barely scratched the surface of the truth? That the universe could be something completely different than what we think it is? Hence the Fermi Paradox? Maybe there is no paradox and the universe is boiling with life all around us and we see it too, we just cant identify it as such because our intellect is still just too narrow and our knowledge too sparse to see more. Imagine intelligent life from elsewhere existing on earth watching us as we discuss if we are alone in the galaxy while it stands right in front of us thinking "man those apes are still quite stupid".... I like that idea way better. It keeps the mystery alive.
I do not need to fear either being alone or not. It is very intriguing either way. I am the only person inside my head That self realization is also very intriguing. All CULTure has control over our freedom to even conceive only what science tells us. Yet science has been so wrong many times over. I believe in an infinite Multi-verse. I believe there is a Singularity that always was is and always will be. All religions are our CULTure as foretold reducing our freedom to think for ourselves with what is real around each of us. Life is very interesting, never boring. The movie "the Circle" with Tom Hanks is very provocative. I love "Issac Asimov" Foundation" series very intriguing. I hope the movie does it justice.
I agree with your limited senses idea... just a few years ago we discovered there are gravitational waves coursing through the cosmos. I do feel humanity has been pondering our place in the cosmos longer than 2000 years. Göbekli Tepe in Turkey dates to 10,000 b.c. Who knows before them?? ✌️
Yes agree with you but I don’t believe we lack the intellect , I believe it’s simpler than that , perhaps we just don’t understand what we are really looking at with regards other life forms . Yes life (as we currently understand) does leave an impact on its environment which we can then measure and even if a life form (an animal ) has long since gone we can be quite sure of its existence at some point . Maybe these signs are undetectable to us as we look out in the Cosmos but then one could also argue that even Alien Lifeforms would consist of elements contained within the Universe, so just like we are all made of star-stuff , then so will they and therefore they should be detectable or the trace of them should be detectable . I don’t think it matters which side of this argument one takes, I think the beauty is in the not knowing, this leaves so much room for speculation and doing what us Great Apes do best , using our imagination. I like to think that our mind is the blank canvass and our brain provides the brushes and paints to let our imagination run wild, run free and for ourselves to create any image or video we so choose . For instance I am right now imagining the Earth as just one of many Cells in a much bigger body and we are, as a species, merely a virus trying to destroy it . Ok my thoughts do have a glaring flaw in them, that being that nuclear weapons would be very hard to explain BUT hey it’s my imagination so MY rules apply 😂
@@rayzorrayzor9000 Nice one. you can extrapolate that idea, and think that each galaxy is a "cell" of something, or each universe is a cell. our importance is decreasing, right? sometimes, we wouldn't even be a virus, but a cancer ... we had a function, but started to present problems, and now, we want to infect other "cells" ...
Love the idea of living our knowledge as heritage for future civilizations. However, once we've colonized 4-5 solar systems there's nothing non-artificial that can kill our species so I'd say let's focus on not dying rather that designing our will.
These videos out of ALL the Space related channels i watch, this one holds my attention unlike any other and honestly, i cherish that fully, thank you for feeding my passion for all things Space.
It is so very difficult to predict. Man exists only because of some chance event occurring just at the right time in the evolutionary process. If the Chixulub impact would have happened a few million years earlier or millions of years later (or not at all) we would likely not be here. the impact was just at the right time to wipe out a set of life forms that were both dominant and ferocious. Only because of the mass extinction event were small mammals given a chance on a planet that had become much more hospitable in terms of offering them a safe-ish haven in which to evolve. I think that in terms of intelligent life as we define it, it is a pretty lonely old Universe out there and if type 1/2/3 civilizations really do exists they would be frequently knocking on our door. Unless humanity was "seeded" on this planet by a type 2 civilization I think the surprise our Galactic neighborhood will hold for us is that it its devoid of any advanced or intelligent life forms. I do not believe in a God but there is a possibility that a long gone civilization went around the galaxy seeding life and/or terraforming, but even the eons have seen their demise.
The section on lunar artifacts strongly called to mind "The Sentinel" by Arthur C. Clarke and the monolith buried under the moon's surface by an ancient alien civilization in "2001: A Space Odyssey". It is strange to think that we, ourselves, may become that ancient civilization
Discovered this channel months ago and got hooked inmediatly, as a fan of Cosmos series since I was a child, back in the 80s. Amazing job, Cool Worlds!
these are the videos, specifically from the cool worlds channel, that I look forward to watching/listening to on the weekends as a leisure activity but also thought provoking and a learning experience to round it off as: one of my favorite things to do!
I love Carl Sagan, everytime I hear him it feels like a far off grandfather still trying to communicate to his people that we might not understand, but that we should never give up. Search, find, think it out and put forth the kind of investigation that allows us to understand what we're doing here. It's not about knowing everything, it's about Learning everything.... Let us be proud of how far we've come. Let our distant selves be proud to take what we've taught them and discover what we could not....
RFID sail. A passive device that when bombarded with an energy source, on a frequency that is most likely to be sourced by an intelligence, rather than a natural one, absorbs the energy and is used to induce a weaker transmission of it's own. This is exactly the principle every RFID card you've waved at a door panel to gain access, functions on. No need to send or maintain a power source or overly complex machinery. Wait for a source to be nearby. This might give the artifact a better chance of being detected when drifting through the vastness of space. Might only be a slight increase in chance, but hey, with the odds you're talking about, take any advantage you can get.
I wish people would get over trying to find intelligent life out there it's not there it took a universe to this size for it to do this one time create us yes I am a spiritual being but my spirituality does not come from the ancient calendar it is a scientific perception of reality which gives me my spirituality 20/20 all seeing eye degeneration
@@michaelward878 I think my comment was pointed at the temporal argument, of life over time. The argument in the video was well made that we may be the only ones in the galaxy at the moment. Some may come after us. How do we communicate with them across time? The RFID sail was a suggestion. Your asertion that we are alone in the whole universe, may, or may not, be accurate. But will we always be? Maybe. Will we still be here when another appears? Maybe. But if not, why not try to communicate with them across time too? Leave something we can share and let them know there have been others. That they're not alone, like we have felt, when considering time.
Every Cool Worlds video is a gem it communicates at a level of science and logic I look forward to every work and video. I feel so much more intelligent mulling oner the data.
Many years ago, when Frank Drake was still relatively unknown outside the circle of astronomers, he gave a talk in Toronto to a small audience. I was just a high school student, but I was familiar with his work because it was discussed among science fiction fans (then a microscopic subculture). By good fortune, I had come across a copy of the first edition of L. Frank Baum's book Ozma of Oz, which had inspired Drake's Project Ozma, the precursor to SETI. I presented it to him at the end of his talk, and he seemed genuinely pleased by the gift. He urged me to diligently pursue my studies, perhaps assuming I was a potential astronomer. In fact, I was more attracted to paleontology than astronomy, and in the end became a historian. But I never forgot this encounter. It still gives me a warm feeling to think of it. He was perhaps the first actual scientist with whom I had a personal interaction, and what I can say about him is that he gave a positive impression of scientists that eclipsed the whole lot of good, bad and middling ones I had in later years. The Drake Equation was both fun and scientifically significant, but it still amounted to guessing what Santa will leave under the tree next Christmas. We may be like the people of ancient Rapa Nui, believing ourselves alone, cast away in an immense ocean and unaware of the teeming millions in the world over the horizon. Or we may be like the first humans passing the ice barrier from Beringia and entering a vast New World uninhabited by other humans. This is a dramatic tale with a delicious cliffhanger, the outcome of which we don't know. Let's enjoy the story during the telling, and accept the surprise ending when it comes.
Perhaps a time capsule on a moon located further out in the solar system that will survive the eventual red giant phase of the sun and therefore last indefinitely. Earth as an island on a cosmic sea reminds me of "Islands" by King Crimson: th-cam.com/video/FPNjQ4JWr9U/w-d-xo.html
Yeah, Earth's moon isn't a good choice to outlast the sun. But we need to find an outer planet moon in a stable orbit around its planet that also has a surface not subject to local "weathering" due to having an active interior caused by tidal heating. I was thinking maybe Neptune's second largest moon, Proteus, but I'm not sure how stable its orbit is. Proteus is only 250 miles in diameter, but has an unusual non-spherical shape, and no tidal heating that we know of. Also, Neptune is pretty unusual too, being the only planet emitting more energy than it receives from the Sun, so it might pique the interest of aliens :-) I was also considering the largest object in the asteroid belt - the dwarf planet Ceres - which is 580 miles in diameter. It's unique in the asteroid belt for that reason, and is also far enough away from the Sun to survive when the Sun becomes a red giant in 5 billion years.
@Johnny Deep We could put it on our moon, that’d be fine because when the aliens come back they’re probably gonna take that giant spaceship that we call “moon” back with them when they leave.
I've often wondered about the possibility that humanity could send out advanced Artificial General Intelligence into the galaxy, fully loaded with the sum total of human knowledge, so that even though we as a species are fated to die without first contact, maybe our knowledge need not suffer the same fate.
Perhaps we ourselves could be the main artifact. Probably not in our biological form but as cyborgs or something. I highly doubt that all sentient species are doomed to extinction, especially if they take certain precautions.
There's an exoplanet which has been found which survived orbiting inside its sun's photosphere. That says the Earth could conceivably survive the red giant expansion of the Sun.
This may be my 10th or 12th rerun on this video. David Kipping and his Cool Worlds lab are the best of the best. May be my favorite channel on any platform. Thank you for what you do Cool Worlds. 😎
20 years is nothing, we are too impatient, too inexperienced yet to make more then a guess, it’s decades, maybe hundreds of years before we can say we’ve answered the question. We should stop this discussion and just keep looking, without having the feeling we are owed an answer. In the mean time, we will learn a thing or two while we keep being entertained by the universe. The message in a bottle scenario does not solve the paradox of our perception of loneliness, when such would be the case, the likelihood of having seen such a message would be many times greater the coexisting at the same point & time: the question would likely be solved much, much quicker, if not already. Therefore: let’s be more patient, but let’s be curious.
Can you explore the idea and implications of, "What if life was found within the solar system?" Can we plug that into everything we've been hypothesising? A practical approach. I think this would make for an interesting topic for many more spots. Thanks in advance.
If we find squid in oceans of Enceladas, it means we have a sample size of 2 living planets instead of 1 - in the same system - meaning life is probably pretty abundant out there.
I love this piece of information causes me a sort of "spiritual" connection with the moment I'm watching this! ... Makes me shift my perspective at least for the time my mind wonders arround the ideas here exposed!!! Great David!!! Thank you!!!
9:05 kinda confused here, you seem to be leaving out the number of stars in the galaxy? there's about 250 billion stars in the milky way. if 1/5th have planets with life, and 5% of those result in civilizations, that's 2.5 billion civilizations. if we assume an even distribution of civilizations for the last 13 billion years, that's 1 civilization per 5.2 years. if they communicate for 100 years, you should see about 20 civilizations at any one time.
The number of stars is essentially accounted for in the star formation rate, you can think of as a time derivative of star number and so by multiplying by L at the end you recover units of a scalar

"Oracle, are we alone in the universe?"
"Yes."
"So there's no other life out there?"
"There is. They're alone too."
we can't get a long with people of our own species, space and time protects us from intergalactic war.
So good.

Agh.
Your video contradicts literally thousands of hours of televised research I've done on this subject, which suggests not only a galaxy abundant with life, but one in which nearly every alien species has adopted the English language as their preferred mode of communication. Live long and prosper.

Cheers guys!
Maybe we are the first in the universe. Maybe the universe is ours to subjugate. Instead of living on one planet complaining about equally, all like minded people can have their own solar system.
@@allisbeneathme3350 yeah but just as the first Americans came like minded and today we have so much diversity so would those solar systems. But i imagine futer explorers will start there own planets and those planets will end up having wars and different skin color and all these differences we have here today. Have a great day and let the universe bless you

Event Horizon JMG, your videos also tend to keep my ongoing existential crisis front and center in my conscience!..propelling it straight towards the cold, dark, lifeless vacuum that our universe will become..GOODNIGHT!
Dear Cool Words team. Your video is a perfect example of an ideal video of science dissemination. To describe it,l some would say that it is pure science, although that is not enough, as it is only analytical in its content; others would call it poetry, perhaps even, a masterpiece. However, I would rather prefer to use the term philosophy in its truest sense; a beautiful homage to the thirst, passion, and veritable love of knowledge. Thank you very much.
Some might even consider it nihilistic... lol
So good to hear Carl communicating intertemporally with us!
Yeah, agreed. Very nice opening surprise.
I used to think he was right, but corny. Apologies.
I MISS that guy something 😕 😪 fierce 😢. At least, in its day, Cosmos was SUCH an excellent series 👏. I NEVER missed an episode. Cosmos and Contact were 2 of my inspirations for studying Electrical Engineering. Thank you Mr. Sagan.
Man I miss his voice and I expect I'm not alone.....
Other than the comedy of him saying you'd have to survey 'dozens' of worlds to find life. More like a near infinity of worlds, for all intents and purposes.
Entropy is like that kid who can't stand losing monopoly so he ruins the game for everyone
And practically speaking its a miracle that the kid stays calm and doesn't sweep the board
Entropy gives life as we know it its meaning.
I guess. It's just Time. It's bigger than us.
I hate monopoly so much
Without entropy you wouldn't be here to have that thought. Keep that in mind.
Prof David Kipping is amazing as a scientist and as a thought-provoking and artistic science presenter. I always relish his way of presenting scientific thought, ideas and speculations.
Carry on Professor Kipping!
Mind blown. Once again. Thanks for another great video, David!
The more I think about it, the more life, consciousness and intelligence seem far-fetched. I mean, were we unbiased, immaterial observers of the universe, how could one possibly imagine such an incredible reality like the one we live in today. Even the most extreme astronomical events, although grandiose, pale in comparison to the unbelievable complexity of life on earth, to say nothing about the human mind. You are right to say that our existence is a precious gift, and we should make the most of it.
Thanks for helping us put things in perspective!

This video just nails it imo. I've always thought this to be the most likely answer to the Fermi Paradox. We might be alone in the galaxy.. At this moment! Don't just think vast distances, but also vast timescales.
I hope we arent alone
I once read somewhere that some astronomer or physicist compared intelligent life to small lights on a Christmas tree. With the tree being the galaxy, and the lights being potential intelligent life.
When speeding up time a gazillion times, the tree looks like a disco ball, with lights turning on and off everywhere all the time.
But in reality, at any one point in time you'd see not a single, one, or mostly a couple lights on simultaneously.
Can't remember where I read that though, but I've always remembered it.
@@MacSvensson I remember what your talking about. It was on PBS channel 13 over 20 years ago and the guy started out with a table full of trimmings for dinner waiting for a lobster to arrive from the ocean and the point was just because the lobster didn't show up didn't mean they didn't exist and then he went on with the Christmas tree lights and I guess it was the drake equation projected on to the xmas tree and the different calculations started to dwindle. Yeah I remember watching that. Your not alone..... get it lol
@@MacSvensson well, it seems that just because i haven't seen these programs, it doesn't mean that the program didn't air
What a delight to discover this channel! You bring such a philosophical, poetic, and distinctly human touch to the exploration of space and the universe.
This made me extremely emotional. Not often does science or galactic concepts like this bring me to tears, but when they do, it's intense. This was amazing, and VERY intense!💜
Dude, space always makes me emotional. The vastness is so beautifully depressing...
Depressing? In a way, yes! I won't live long enough to get to see enough of it. Or, that I was born too damn early. 😟☹😪😭. That i won't get to understand, or experience enough of it...etc etc ☹. Depressing indeed. I'm SOOO small 😭. WE are so small...far less than a blink in time. Merely a few more atoms in the vastness of the universe. 😢
Are we going to make it?
Watch all cool world videos, more tears to come. In a refreshing, cathartic way 😊 brilliant
Time travel one, how big is the universe (the last part about an infinite universe and its consequences)
From the first few seconds in the opening until the end I felt the same.
Alien Signal:
"Do not broadcast. They will see you."
Then it is already too late.
I can't remember where that line is from.
They have already seen us and we scare the hell out of them!
Inverse square law says that this is basically impossible. They'd have to live close enough to us to pick up that signal that we would be able to observe the effects of their existence on their host planet. If a radio signal is powerful enough to make it to them, then their visible light is bright enough to make it to us.
If they don't receive stellar energy to heat their planet enough for biological life to form, then they would require internal heating mechanisms to provide that heat, and then we'd be able to observe that planet in the infrared spectrum instead.
Sorry to say, we are almost definitely alone and probably always will be.
Funny thing is, it probably isn't the tv signals that will give us away if life beyond Earth does actually exist. Do you have any idea at all just how bright a nuclear explosion is? And do you have any idea how many atmospheric detonations of nuclear weapons have occured in mankind's history? It's a LOT. One of those bombs, Tsar Bomba, was so powerful that the shockwave it generated was still detectable without scientific instrumentation on it's 3rd passage around the globe. As in, you could feel the Earth react beneath your feet to this blast from the other side of the planet on it's third go around. There is NO WAY WHATSOEVER that at least one of these nuclear blasts didn't attract the attention of any astronomy-studying sentient aliens if they're even remotely nearby. These blasts would have highlighted our planet on multiple occasions. I wouldn't be surprised if our usage of nuclear weaponry was both our announcement of our existence, and the act that condemned us to solitary isolation even if other sentient life-forms do exist out there.
I lack the ability to adequately articulate how much I love these videos. Carl Sagan has been important to me my entire life, and the wonder he instilled in me, persists to this day. I look up at the night sky, because he first showed me its beauty.
Cordatus Scire Cordatus, you just demonstrated your powers of articulation. Thank you-and I agree with you regarding these incredible visual, aural essays.
yes. Yes, that exactly.
My fascination with what lies out there is what pushed me to study, the sheer amount of possibilities, the idea that nothing is impossible, but improbable, just becuase we haven't observed life as we know it, doesn't mean that there could be interdimensional beings, of even corporeal life for that matter.
Carl Sagan was both a physicist and a poet, perfect mix to show the world how humbling the universe is. David Kipping is a physicist that shares the same feelings we all have at huma level.
"Life looks for life". I felt that. Powerful words.
but the sentence has an end: "to feed on it."
What else?
In the natural universal nature,....to conquer.
Reminds me of the book The Alchemist, when the boy gets sent out on the dessert to survive and he finds a snake because if there is life there is water. Life begets life.
Dr Kipping as always great, understandable content involving different branches of science. Shared with many people!
He is a professor not a doctor.
@@colinp2238 He has a Ph.D. in astronomy!
A P.h.d. is a doctorate if I'm not mistaken. So he would in fact be a Doctor. If I am perhaps wrong, he none the less deserves the title. Hell always be a Dr. to me. Lol.

To each their own eh?
“Arbiter, is anyone out there?”
“We may never know Master Chief, the truth belongs to no one”
Humanity has gone from thinking ourselves to be special, like the belief we are in the image of God, to science and rationalism showing we aren't so special we are one species on one little planet. If we are indeed alone than we are special. There's something poetic about that.
We are special unique made in Gods image! I believe this is the only planet with life..if there is life elsewhere then god hasnt told us, not important for us to know, we gotta get right here, on this planet!!!

It is a child-like and deeply moving compulsion of ours to want to make sense of it all, and then so desperately to wish we could show someone what we have done. As if we look for someone just to mark our homework, correct our mistakes and maybe give us a kind green tick, if only for effort.

Excellent video!

"There's a very low probability that'll find alien life withing 20 years. Maybe"

That's a bold strategy Cotton! Let's see if it pays off...
20 years is nothing, we are too impatient, too inexperienced yet to make more the a guess, it’s decades, maybe hundreds of years before we can say we’ve answered the question. We should stop this discussion and just keep looking, without heaving the feeling we are owed an answer.
Didnt Seth Shostak say in 2005 he'd buy everyone a starbuck's coffee is we havent detected a SETI signal within 25 years? 5 years to go, Seth!
Every time I listen to this, my own wistful, half-sad suspicion is verified-we are very likely alone. Certainly David bolsters my persistent doubts that anyone waits for our phone call somewhere in the Milky Way, or even in the Observable Universe, as another sentient, volitional, technologic civilization that has not yet obliterated itself or its home planet. All the more reason, then, to treat each other as fellow volitional sentients-with magnanimity, humility, kindness and shared exhilaration.
I've just found out this video on my recommendation, what a wonder it has been to discover this channel! Cheers from Switzerland
Welcome to Cool Worlds

When i was a kid i picked up a broken balloon in a field with a string on it. A message was attached to the string. The message came from a church in Detriot . The message was something about how far God's will travel. i lived in london Ontario Canada at the time. And was going to write the sender back but i lost the sender's address and church name. This was in the 1960's.
I think that God just wanted to go somewhere, anywhere that wasn’t Detroit, can you blame him 😂

It's so good to hear other people thinking and communicating deeply. The mind is a restless place that never seems to be silent. This channel is really great! Also maybe we are alone in our galaxy but if you expand the search into the entire universe then the chances of finding life go up infinitely!
His teeth are the real artifact. Look at those things, they are exquisite.
The fact that all you think about are his teeth when hes speaking about such profound ideas is rather sad
I used to have a hypothesis that each galaxy was only capable of supporting one civilisation at a time. Mainly because of the fact that large parts of the galaxy are pretty inhospitable what with, supernovas, gamma ray bursts and so on.
Man, I wish I could talk about this stuff with my friends, most of them just glaze over if I try and engage them with this type of discussion.
Ikr,
Although I actually think our galaxy should be large enough for quite a few civilisations, space is large and actually there isn't a real need to colonize planets, of course it would be nice, but O'niel cylinders are definitely a good option too. Our galaxy is 100.000 light years across, has billions of stars, yeah most of them are in less hospitable places, but life could've originated from somewhere else, but used technology to conquer those challenges.
But this all assumes that some type of Warpdrive is feasible, if it isn't then large interstellar empires are a bust anyways.
I, too, would love to have an intelligent friend.
I love this presentation, I never get tired learning by lestining about this topic, is us our story from the star dust back up to take our place among the stars,I read and lestin this kind of presentation topic.I spend 6-8-12 hrs a day 7 days a week I am 72 yrs old and I have all my time spending this educational matter that the school don´t teach us.Is amazing leason also is a gift that enternet is been created for us to be consciously awaken our spiritual soul and understand we are at the infinite spiritual soul journey.
I like watching these types of videos to gain some hope for humanity and then immediately dashing those hopes by going onto 4chan.

You think that's bad, try going on Twitter sometime. I don't recommend it.
We are separated by huge distances of time and space. However, consciousness has no said boundaries.😎

I’m so dumb I still can’t fully understand when he breaks it down to basic math. But I continue to watch all his videos.
IMO, the abiogenesis of life on earth was a gigantic cosmic accident. Or it was so improbable that the abiogenesis of life happened, when life was never supposed to exist, so to speak. And I don't buy the numbers game.. just because there are trillions of galaxies, stars, planets does not mean life is common or extremely rare. Once we understand (if humans ever do) how life on earth began..it will emphatically suggest that life was a freak cosmic accident. As such, life on earth is supremely precious and special that we need to completely change the way we live so that the destruction of life (caused by humans) will cease completely.
We need to protect the only known environment capable of supporting and sustaining life. Alas, vast majority of people simply do not care.. which is a tragedy for all species that Earth harbors.
Exactly. The chemistry needed for abiogenesis may be universal, but the exact conditions that such chemistry needs to occur in to create life certainly are not.
The point that it started soon after the formation of the earth could mean life is ubiquitous.
If we think of matter as having a natural propensity to organise itself, then abiogenesis follows.
Intelligent life is another matter though. Why did it take so long to wait for us?
I like your sentiment, but even if (intelligent) live is abundant I would still argue we need to save humanity. (But not as the plague we are now) and even at a local level, distances might be so overwhelming we might as well be alone.
There does not seem to be enough intelligent life on earth to coordinate a global thought process & to both preserve our habitat & ensure our survival beyond, perhaps, 2100.
You sound like a catholic priest talking to Copernicus, arguing why the earth is special (I actually agree with your opinion though, just a fun comparison)
Star Trek's next generation episode "The Inner Light" comes to mind a message in a bottle. I recommend that we do the same as in this episode so when we go extinct as a result of asteroid or nuclear war. A future civilization can learn from our mistakes.
My absolute favorite episode from Star Trek Next Generation. So thought provoking and profound!
Will there be any civilisation after we are gone extinct?
Id say if instead of when, though
Your content and method of delivering it is as close to perfection for me as ive seen. Its science meets childhood wonder.
What a time it has been; look at that view. If only there was someone to share it, discuss it. Are we just moping about without a lover as we kick pebbles with our boots. Do we need to accept something or embrace something? Expectation only leads to disappointment but yet we yearn to be not alone.
What a beautiful and thought provoking message. I had chills down my spine and tears in my eyes when I heard Carl's voice again. Thank you, so much.
The poetry of Dr. Kipping moves the soul.
He could be right or wrong about these far-flung assumptions, yet, does it really matter?
The main focus and value of it is that it sets the responsibility of preserving life and knowledge beyond our time, and also high marks the extremely valuable gift that it represents.
¿Are we alone?
¿Are we surrounded by like-minded beings staring at each other in silence through the voids of time and space?
Only time will tell, yet before and beyond that, it is our duty to preserve the precious spark we represent, today.
I find it unlikely if a lifeform evolved elsewhere it would reassemble anything like what we have here. Even small environmental changes would drastically effect life there.
One of the major premises for this video right from the start is that people are social creatures. If for example we evolved on a planet with less competition we wouldn't have needed to work together and likely wouldn't have turned out to be so social. There could be a highly intelligent species out there right now that simply has no interest in communicating with us, at a genetic level. Or anyone else for that matter.
We are also colonizers, we crossed the ocean without knowing what we'd find, we map and search every inch of the planet, we went to the Moon just to prove that we could. Not every lifeform would necessarily have this desire to reach for the stars.
There could be a lifeform out there right now that spends almost it's entire life in hibernation and only wakes up occasionally to eat while still being a thousand times more intelligent than we are. There might be a lifeform out there that kill each other on sight and spend their lives in hiding and reproduces a-sexually with a negative desire to communicate with others. The possibilities are endless.
Looking for intelligent life with the technology and desire to communicate is already making an incredible number of assumptions about that lifeform. But then include their desire to communicate not just among themselves but with other foreign lifeforms as well...
This is already an incredibly specific lifeform with highly specific behaviours and highly specific desires we are looking for. At this point we aren't looking for aliens, we are looking for more of ourselves.
Hands up if you read this in the same metered out vocal tone as the presenter of this video..
“.....for the moment the Earth is where we make our stand.”
Its so hard for us to appreciate the incredible oasis of seeming perfection, that we live on.
Great content. Your writing and delivery is almost poetic.
These videos seem to touch my soul on a personal level. Thank you for always producing fantastic content!
Better than a year later, and David Kipping is still on point and as interesting as when the video was originally published. These videos don't always say what I want to hear. They let me hear what we to this point truly know.
Thanks Cool Worlds.
My thought at the beginning of this video was of David Brin's short story, "The Crystal Spheres". (note: started to describe why, but it's really a wonderful story, and don't want to give anything away to anyone who wants to check it out, so no spoilers). His intent was to provide a novel explanation of the Fermi Paradox. It has some science fiction and even fantastical elements, not just pure science -- but the sentiments here are (in part) the same, I think -- in both the loneliness and the majesty.
A second echo that I heard was from a Star Trek episode, "The Inner Light" I think it was called, with a doomed race deciding to leave a piece of themselves, in a novel but deep way. Probably the most beautiful episode in the series, IMO.
And a third one (this is turning into a "recommended reading list"!): Olaf Stapledon's "Last and First Men". No message left, in any direct physical sense, but there's a strong theme of a story being told through history, and that story endures in its own subtle way. It's from nearly a century ago, so the language strikes some as a bit stilted (he was British, too ;), and male-centric, but it is does implicitly address the question of finding meaning, and facing the end without fear and regret.
My favorite temporal comunication in Science Fiction was from Picard season 1. An ancient and powerful intelligence had moved 8 suns into perfect orbits which can't occur in naturally (according to this fiction). Loved this video. It's my favorite Cool Wolds video (so far)
You are the next Carl Sagan, Neil DeGrasse Tyson, Brian Cox! LOVE all your videos!
The messages to future civilizations reminds me so much of the Prothean beacons and the blueprint of the Crucible in the Mass Effect Trilogy. Every civilization added something to it in their cycle...Let's just hope that the Reapers don't exist >_>
Wonderful video, love your channel

Wow... I was lost in my own thoughts after listening to your story and presentation about time and space. I feel the vibes. This video is amazing!
The peculiar irony of being "self aware" is that we find it jarring to imagine that we are the only ones who possess intelligent consciousness. But of course, it would seem discomfiting. That perhaps, is the burden of being conscious.
Your Message is so powerful and Contains overwhelming knowledge ❤
This guy's voice reminds me of kurzkazagct. Soft and soothing, gentle and hypnotic. Very enjoyable and easy to listen to for hours. Heck I get ready for work listening to these videos.
Really feeling a numinous Nolan/ Zimmer vibe with this video. I'd like to see a film from them based on this premise.
Hell yeah!
This video just reached me across time and brought me plenty of knowledge 😅
I wonder if there would be passive "techno signatures" that would linger to be found after an alien civ is gone, the way that in biology today we see DNA as a kind of "signature" left from some long gone RNA-only/precursors.
When all is said and done, life seems to have emerged on Earth only once, even though we seem to regard this as quite a hospitable planet, with plenty of energy, carbon, materials, and water. My sense is that life may indeed be exceptionally rare, even infinitesimally rare.
There is a proverb in Persian:
"Don't play with the tails of a sleeping lion."
We seem to be doing that for the few decades.
When the lion wakes up, we won't be able to put him back to sleep anymore.

These videos are always done so well. Drawing me in with fascinating concepts, then keeping me engaged with wonderful language, music, and content.
How about that: Humanity tries to figure out what the universe is and how it works since, who knows, maybe since 2000 years in a somewhat structured manner. Since 100 years we tried really hard with tons of different approaches. During the 2000 years, our picture of what the universe is changed multiple times in quite dramatic ways.
Now imagine how limited our senses are, how confined our thinking. Is it too far fetched to conclude that in our efforts to understand something that is unimaginable older and bigger than we are, we barely scratched the surface of the truth? That the universe could be something completely different than what we think it is? Hence the Fermi Paradox? Maybe there is no paradox and the universe is boiling with life all around us and we see it too, we just cant identify it as such because our intellect is still just too narrow and our knowledge too sparse to see more.
Imagine intelligent life from elsewhere existing on earth watching us as we discuss if we are alone in the galaxy while it stands right in front of us thinking "man those apes are still quite stupid".... I like that idea way better. It keeps the mystery alive.
I do not need to fear either being alone or not. It is very intriguing either way. I am the only person inside my head That self realization is also very intriguing. All CULTure has control over our freedom to even conceive only what science tells us. Yet science has been so wrong many times over. I believe in an infinite Multi-verse. I believe there is a Singularity that always was is and always will be. All religions are our CULTure as foretold reducing our freedom to think for ourselves with what is real around each of us. Life is very interesting, never boring. The movie "the Circle" with Tom Hanks is very provocative. I love "Issac Asimov" Foundation" series very intriguing. I hope the movie does it justice.
I agree with your limited senses idea... just a few years ago we discovered there are gravitational waves coursing through the cosmos.
I do feel humanity has been pondering our place in the cosmos longer than 2000 years. Göbekli Tepe in Turkey dates to 10,000 b.c. Who knows before them?? ✌️
@@matthanrath497 Isaac arthur has an excellent youtube channel which you might enjoy, filled with hypothetical scifi awesomeness!
Yes agree with you but I don’t believe we lack the intellect , I believe it’s simpler than that , perhaps we just don’t understand what we are really looking at with regards other life forms . Yes life (as we currently understand) does leave an impact on its environment which we can then measure and even if a life form (an animal ) has long since gone we can be quite sure of its existence at some point . Maybe these signs are undetectable to us as we look out in the Cosmos but then one could also argue that even Alien Lifeforms would consist of elements contained within the Universe, so just like we are all made of star-stuff , then so will they and therefore they should be detectable or the trace of them should be detectable .
I don’t think it matters which side of this argument one takes, I think the beauty is in the not knowing, this leaves so much room for speculation and doing what us Great Apes do best , using our imagination.
I like to think that our mind is the blank canvass and our brain provides the brushes and paints to let our imagination run wild, run free and for ourselves to create any image or video we so choose .
For instance I am right now imagining the Earth as just one of many Cells in a much bigger body and we are, as a species, merely a virus trying to destroy it .
Ok my thoughts do have a glaring flaw in them, that being that nuclear weapons would be very hard to explain BUT hey it’s my imagination so MY rules apply 😂
@@rayzorrayzor9000 Nice one. you can extrapolate that idea, and think that each galaxy is a "cell" of something, or each universe is a cell. our importance is decreasing, right? sometimes, we wouldn't even be a virus, but a cancer ... we had a function, but started to present problems, and now, we want to infect other "cells" ...
Hearing Carl's voice from wherever (or whenever) he is now made my heart sing tbh
Love the idea of living our knowledge as heritage for future civilizations. However, once we've colonized 4-5 solar systems there's nothing non-artificial that can kill our species so I'd say let's focus on not dying rather that designing our will.
These videos out of ALL the Space related channels i watch, this one holds my attention unlike any other and honestly, i cherish that fully, thank you for feeding my passion for all things Space.

It is so very difficult to predict. Man exists only because of some chance event occurring just at the right time in the evolutionary process. If the Chixulub impact would have happened a few million years earlier or millions of years later (or not at all) we would likely not be here. the impact was just at the right time to wipe out a set of life forms that were both dominant and ferocious. Only because of the mass extinction event were small mammals given a chance on a planet that had become much more hospitable in terms of offering them a safe-ish haven in which to evolve. I think that in terms of intelligent life as we define it, it is a pretty lonely old Universe out there and if type 1/2/3 civilizations really do exists they would be frequently knocking on our door. Unless humanity was "seeded" on this planet by a type 2 civilization I think the surprise our Galactic neighborhood will hold for us is that it its devoid of any advanced or intelligent life forms. I do not believe in a God but there is a possibility that a long gone civilization went around the galaxy seeding life and/or terraforming, but even the eons have seen their demise.
Thought provoking, emotive and deeply philosophical. Beautifully spoken. This is an exceptional video monologue, thank you.
I missed This GREAT teacher and Somebody I am proud of learning 'from'..."depressing not all Men are as noble in oration.."
Excellent content, scientifically and philosophically rich. Thanks bro!
People are made to be together. Nobody can't live in loneliness... Therefore, life is precious, let Love guide you! Peace and Love to all. 💙💙💙
The section on lunar artifacts strongly called to mind "The Sentinel" by Arthur C. Clarke and the monolith buried under the moon's surface by an ancient alien civilization in "2001: A Space Odyssey". It is strange to think that we, ourselves, may become that ancient civilization
Discovered this channel months ago and got hooked inmediatly, as a fan of Cosmos series since I was a child, back in the 80s. Amazing job, Cool Worlds!
Great video it's a sad concept but the idea of leaving behind a monument to be found is in some ways sad but beautiful. Thank you for this video Sir.
Listening to you think aloud for even 5 minutes is enough to prompt the emergence and evolution of science fiction story ideas.
All these years on and Sagan still gives me chills 😎
these are the videos, specifically from the cool worlds channel, that I look forward to watching/listening to on the weekends as a leisure activity but also thought provoking and a learning experience to round it off as: one of my favorite things to do!
Intelligent life is so rare it's becoming difficult to find on this planet.
Dario. I wanna be your friend, that was hilarious 😂
I love Carl Sagan, everytime I hear him it feels like a far off grandfather still trying to communicate to his people that we might not understand, but that we should never give up. Search, find, think it out and put forth the kind of investigation that allows us to understand what we're doing here.
It's not about knowing everything, it's about Learning everything....
Let us be proud of how far we've come. Let our distant selves be proud to take what we've taught them and discover what we could not....
RFID sail. A passive device that when bombarded with an energy source, on a frequency that is most likely to be sourced by an intelligence, rather than a natural one, absorbs the energy and is used to induce a weaker transmission of it's own. This is exactly the principle every RFID card you've waved at a door panel to gain access, functions on. No need to send or maintain a power source or overly complex machinery. Wait for a source to be nearby. This might give the artifact a better chance of being detected when drifting through the vastness of space. Might only be a slight increase in chance, but hey, with the odds you're talking about, take any advantage you can get.
I wish people would get over trying to find intelligent life out there it's not there it took a universe to this size for it to do this one time create us yes I am a spiritual being but my spirituality does not come from the ancient calendar it is a scientific perception of reality which gives me my spirituality 20/20 all seeing eye degeneration
@@michaelward878 I think my comment was pointed at the temporal argument, of life over time. The argument in the video was well made that we may be the only ones in the galaxy at the moment. Some may come after us. How do we communicate with them across time? The RFID sail was a suggestion. Your asertion that we are alone in the whole universe, may, or may not, be accurate. But will we always be? Maybe. Will we still be here when another appears? Maybe. But if not, why not try to communicate with them across time too? Leave something we can share and let them know there have been others. That they're not alone, like we have felt, when considering time.
Every Cool Worlds video is a gem it communicates at a level of science and logic I look forward to every work and video. I feel so much more intelligent mulling oner the data.
Thank you for the video. It opened my eyes and made my day :)
Many years ago, when Frank Drake was still relatively unknown outside the circle of astronomers, he gave a talk in Toronto to a small audience. I was just a high school student, but I was familiar with his work because it was discussed among science fiction fans (then a microscopic subculture). By good fortune, I had come across a copy of the first edition of L. Frank Baum's book Ozma of Oz, which had inspired Drake's Project Ozma, the precursor to SETI. I presented it to him at the end of his talk, and he seemed genuinely pleased by the gift. He urged me to diligently pursue my studies, perhaps assuming I was a potential astronomer. In fact, I was more attracted to paleontology than astronomy, and in the end became a historian. But I never forgot this encounter. It still gives me a warm feeling to think of it. He was perhaps the first actual scientist with whom I had a personal interaction, and what I can say about him is that he gave a positive impression of scientists that eclipsed the whole lot of good, bad and middling ones I had in later years.
The Drake Equation was both fun and scientifically significant, but it still amounted to guessing what Santa will leave under the tree next Christmas. We may be like the people of ancient Rapa Nui, believing ourselves alone, cast away in an immense ocean and unaware of the teeming millions in the world over the horizon. Or we may be like the first humans passing the ice barrier from Beringia and entering a vast New World uninhabited by other humans. This is a dramatic tale with a delicious cliffhanger, the outcome of which we don't know. Let's enjoy the story during the telling, and accept the surprise ending when it comes.
Omg this is so superb. Speechless.
Indeed, Life searches for Life 🖖
I loved this presentation. So thought provoking. Thank you and much love
What an amazing, thought provoking video. Definitely worth my subscripton to your channel, bravo sir!
This is the best, most accurate thing I’ve seen on the subject. Thank you. Live long and prosper my friend.
Perhaps a time capsule on a moon located further out in the solar system that will survive the eventual red giant phase of the sun and therefore last indefinitely. Earth as an island on a cosmic sea reminds me of "Islands" by King Crimson: th-cam.com/video/FPNjQ4JWr9U/w-d-xo.html
Yeah, Earth's moon isn't a good choice to outlast the sun. But we need to find an outer planet moon in a stable orbit around its planet that also has a surface not subject to local "weathering" due to having an active interior caused by tidal heating. I was thinking maybe Neptune's second largest moon, Proteus, but I'm not sure how stable its orbit is. Proteus is only 250 miles in diameter, but has an unusual non-spherical shape, and no tidal heating that we know of. Also, Neptune is pretty unusual too, being the only planet emitting more energy than it receives from the Sun, so it might pique the interest of aliens :-) I was also considering the largest object in the asteroid belt - the dwarf planet Ceres - which is 580 miles in diameter. It's unique in the asteroid belt for that reason, and is also far enough away from the Sun to survive when the Sun becomes a red giant in 5 billion years.
@Johnny Deep
We could put it on our moon, that’d be fine because when the aliens come back they’re probably gonna take that giant spaceship that we call “moon” back with them when they leave.
I've often wondered about the possibility that humanity could send out advanced Artificial General Intelligence into the galaxy, fully loaded with the sum total of human knowledge, so that even though we as a species are fated to die without first contact, maybe our knowledge need not suffer the same fate.
Perhaps we ourselves could be the main artifact. Probably not in our biological form but as cyborgs or something. I highly doubt that all sentient species are doomed to extinction, especially if they take certain precautions.
There's an exoplanet which has been found which survived orbiting inside its sun's photosphere. That says the Earth could conceivably survive the red giant expansion of the Sun.
This may be my 10th or 12th rerun on this video. David Kipping and his Cool Worlds lab are the best of the best. May be my favorite channel on any platform.
Thank you for what you do Cool Worlds. 😎
20 years is nothing, we are too impatient, too inexperienced yet to make more then a guess, it’s decades, maybe hundreds of years before we can say we’ve answered the question. We should stop this discussion and just keep looking, without having the feeling we are owed an answer.
In the mean time, we will learn a thing or two while we keep being entertained by the universe.
The message in a bottle scenario does not solve the paradox of our perception of loneliness, when such would be the case, the likelihood of having seen such a message would be many times greater the coexisting at the same point & time: the question would likely be solved much, much quicker, if not already. Therefore: let’s be more patient, but let’s be curious.
Ive watched space videos for years on TH-cam but your content adds so much to concepts I already love
Can you explore the idea and implications of, "What if life was found within the solar system?" Can we plug that into everything we've been hypothesising? A practical approach. I think this would make for an interesting topic for many more spots. Thanks in advance.
If we find squid in oceans of Enceladas, it means we have a sample size of 2 living planets instead of 1 - in the same system - meaning life is probably pretty abundant out there.
I love this piece of information causes me a sort of "spiritual" connection with the moment I'm watching this! ... Makes me shift my perspective at least for the time my mind wonders arround the ideas here exposed!!! Great David!!! Thank you!!!
9:05 kinda confused here, you seem to be leaving out the number of stars in the galaxy? there's about 250 billion stars in the milky way. if 1/5th have planets with life, and 5% of those result in civilizations, that's 2.5 billion civilizations. if we assume an even distribution of civilizations for the last 13 billion years, that's 1 civilization per 5.2 years. if they communicate for 100 years, you should see about 20 civilizations at any one time.
The number of stars is essentially accounted for in the star formation rate, you can think of as a time derivative of star number and so by multiplying by L at the end you recover units of a scalar

Probably best not to pull estimates for Drake variables out of thin air (or other uncomfortable places). Such analysis is not worth much.
