  • There's a plausible chance that we may be alone in the galaxy right now. But the odds that the galaxy has never, and will never, host other civilizations is far less likely. Today we explore the possibility of communicating through time, and how such a feat might be accomplished.

      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 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.

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.

    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.

    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.

All the more reason, then, to treat each other as fellow volitional sentients-with magnanimity, humility, kindness and shared exhilaration.

    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.

    • @tristanb123

    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.

    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.

    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.

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.

      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" ...

    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.

      @@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.

    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

    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.

    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.

    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: czcams.com/video/FPNjQ4JWr9U/video.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.

      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.

      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.
