I really like the Firstborn idea because it offers the possibility that we are alone in the universe...for now. It's kind of like getting up way early in the morning while everyone else in the house is still asleep. You can get yourself some coffee and cereal, turn on the TV, put the sound down low and watch cartoons, and just generally enjoy the quiet. It also gives us the opportunity to prepare the universe for the coming of the next species--to theorize what they might be like, and shape worlds and stars for them accordingly. It's almost God-like--at least in theory. It goes without saying that whether there's a God or not, we're nowhere near that level of power, and we will have to fix an awful lot of our own problems before we're ready to take on anyone else's.

I have read an interesting argument for why we should expect to be this universe's first and lone intelligent species. It goes like this: 1- In nature, processes that make more than one instance of a given type of object make more small versions of those objects than big ones. 2- A process like eternal inflation that continuously spawns new bubble universes would make more small universes than big ones. 3- A universe needs to have a certain minimum size to have the ability to spawn an intelligent lifeform. 4- Since there are more small universes than big ones, the probabilities are that our universe's size is close to that minimum size. 5- Therefore, we should not expect to see very many, if any, intelligent species sharing the universe with us. Not compelling by any means, but still interesting to ponder.

what i've been toiling over for the past few months with the idea of Quantum Mechanics is the example you gave with 10^27 to be the likelihood that an atom is part of a human brain at a given time. with understanding quantum entanglement (as einstein suggested), you could codify these likelihoods with biology itself. i could spit on the ground (with DNA unique to me), and that would create infinitely more vast likelihoods that i personally contained this inherent likelihood of 10^27, and actively utilize it to spread, at this likelihood rate. essentially, deducing the likelihood into a potentiation, and the propagation of those effects as potentiation-thresholds being collapse (wave-function collapse in quantum mechanics). therefore, simply spitting on the ground would create more calculatory-chaos for any system designed to monitor or calculate those likelihoods. if anyone ever wondered how to 'escape' a simulation, they might first try to learn the limits of that simulation; simply spitting, should (in theory) cascade these calculations--however, you might realize that you had been doing this, this entire time since birth. we spit and salivate a lot without realizing it, and there are at least 8 billion of us. this 'simulation' would therefore have to be seemingly infinitely complex. you might start conceptualizing slices of Earth as needing to at LEAST be in the purview of a Jupiter-sized Computer Brain, just as a BASE requirement for your continued existence moment-to-moment. i enjoyed the example you gave concerning the consolidation of human history. if you indeed condensed Earth's existence such that each day is equivalent to 12 million years, you could extrapolate out these potentials (Humanity's expansion) into vague likelihoods, future dates of our first interstellar colonies, and so on by understanding our technological process, thus far. any alien civilization that also knew numbers, could expect certain things as well. the ONLY part where this breaks down, however, is on a psychological scale. what if we just decided it was suddenly boring to do so? then we would no longer meet the expected requirements. akin to how Hawking could establish the likelihood of Time Travel, but would be shown-up if we decided either Hawking himself, or Time Travel was boring. what further cascades this line of reasoning is the 'spice of Life', as i call it. the rate at which a biological system considers itself having a 'thought'. what if it DID have a thought every 12 million years? the Universe would exist in this 'sped-up' state from its perspective (akin to Red-shift and Blue-shift differences). also, not to mention the planetary brain hypotheticals--at what rate are the aggregate of those thoughts? so many questions; as John Wheeler wondered: whose BIT?

This is the thing that I never understood about the perplexity over the Fermi Paradox. A 20,000 year old interstellar empire which is engaging in stellar engineering that exists on the other side of the zone of avoidance 60,000 light years away would be utterly undetectable to us for at least 40,000 years. I know the presumption is that "well there have been 13 billion years for life to evolve, so where is everyone" but space is fucking enormous, and life certainly hasn't existed the entire 13 billion years. The METI signal we sent out would be by our very own standards not enough evidence of alien life because it didn't last long enough. It would literally be a WOW signal to an alien species, and if we want to act like the METI signal is our way of saying hello, it is just as likely that the WOW signal was another species' own METI signal, by that standard. The ability to detect alien life has only been theoretically possible for a few decades, and only under perfect circumstances that would, by our very own scientific standards, not last long enough to confirm either way, just like the WOW signal. We'd have to be looking at exactly the right point in space at exactly the right time, and that is all assuming that the alien civilization who sent the signal was using radio frequencies that we're tuned too, if they use omni-directional radio at all, AND assuming that the signals were close enough and powerful enough to not be drowned out by cosmic radiation. It would have to be a truly, exceedingly powerful signal to survive for tens of thousands of light years at the duration necessary to fully confirm alien life. I don't doubt that life might be "new" to the stage of the Universe, but that's highly relative at cosmic time scales. The Milky Way could have 100 space faring, interplanetary or even interstellar civilizations in it, all technologically advanced enough to send signals out, all of them 3X as old as ours at the very least. Out of 200 billion stars, the odds of accidentally surveying one of them with JWST for signs of industry or biologicals in the atmosphere is 0.0000000005%, and that's assuming that they're close enough that the atmospheric signs of industry will have reached us through the light waves, meaning that the civilization would also have to be old enough for that light to have passed through space, and therefore almost assuredly older than us. That's also assuming that they exist on this side of the zone of avoidance so we can survey their system at all. The question of detecting alien life is as much a question about time as it is distance, as the speed of light puts hard limits on what we can expect to hear even hypothetically, and the distances involved put lower limits on how powerful those signals have to be, to the point that any civilization at sufficient distances from Earth would have to be deliberately *trying* to be heard to be detected by us, and likely would have had to chose to send that signal directly at the Sol System on purpose to ensure we heard it. And we'd have to be listening in the right direction, at the right time, for the right amount of time, to pass our scientific standards for first contact. Oumuamua was an interstellar body with mysterious properties that flew through the solar system and mysteriously accelerated while it was leaving the system. All kinds of natural phenomena have been put forth to explain it, but still, if Voyager enters the solar system of an alien race just far enough away to be little more than a dot in the telescope's eye, and that race is just as scientifically skeptical as we are, they likely would come up with all manner of natural explanations for what it could be first before concluding aliens. And rightfully so; my point is simply that our ability to search is so limited, and has only existed for such a short amount of time, that the essential question behind the Fermi Paradox has always seemed exceedingly arrogant to me--doubly so if the conclusion is "we must be among the first, if not the first." If our very own signals wouldn't pass our very own standards of evidence for alien life, isn't it presumptuous to conclude that we haven't seen or heard anything already?

I am also equally sad by the idea that in the far future , any civilisation that arises will only ever know that their galaxy is the only one in the universe , since expansion will have moved every other one out of view ... and by then there might not be any cosmic background microwave radiation left for them to ever discover how our universe was born... This gives me an existensial crysis but also makes me realise how damn lucky we have been able to obsrve all this and just how important it is to study astronomy ... The above scenario I just laid out is not one where we are de facto alone , but for all practical purposes , we are thanks to the expansion of the universe ... it and entropy are the two things i hate the most about the universe ... actually scratch that , i would be fine with the expansion if it couldnt go faster than light and it would suck even more if the universe was contracting rather than expanding, but entropy is the most inevitable thing that ensures that everything we do today will one day die in the far future I hate entropy the most

On the other hand the realization or the probability that all the available sapient species throughout the universe or within our galaxy being tribal to medieval ages at best makes humans go conquistador mode really, seriously fast. Imagine James Camerons Avatar but essentially RDA always *always* winning and subduing ( maybe forcibly integrating ) the species

Have a look at all the Fermi paradox videos. It's extremely unlikely that any other species is within a few thousand years of our own development. Or even wothorna few million years. (Which they would need to be to be mediaeval or tribal etc.) In the next million years, the only thing that would keep us from taking over the galaxy would be extinction. The same applies to any other intelligent, toll using species. We don't see any aliens having taken over the galaxy. Hence we must conclude that we are likely to be the first.

assuming that we are among the first tech civilisations if not the first one, is actually seems reasonable. you say (like lot others) billions of years. ppl tend to forget that the universe is insanely young. the third generation stars are the first ones wich are capable to support life. our star is among the first third generation stars. also, our star is quite unique. despite its size and age (its bigger than average and middle aged being 5 billion years old) it is incredibly calm for a star. its not too big, so it has enough slifespan to support life in its planetary system, and its not too small, so with its age it was able to calm down even further. (by calm i mean the changes in its brightness is about 0.1 per cent or so, wich is extreemly rare ) so, all things considered, even if a trilion years from now the galaxy will be filled with intelligent life, it seems unlikely it is filled up with that now.

@@thedoruk6324 Yes, we probably wouldn't be able to detect a civilization that only has at most a handful of systems. But within a million years, humanity herself would have settled the whole galaxy. Thus there's only an incredible short amount of time, on astronomical scales, between first space flight and conquest of an empty galaxy. And even with our current instruments, we would be able to tell if the whole galaxy was settled with Dyson Swarms.

The earth has had one technologically advanced species out of roughly 1 billion species that have ever lived. Our galaxy may have around 10 billion earth-like planets and there are around 100 billion galaxies, all conservative estimates. So there could be roughly 1000 species similar to us in the entire universe. If we are evenly distributed across space, it means we will never contact one another.

The bear, beehive, amoeba, bacteria analogy is pretty flawed. It would be more like uncontacted tribes of humans living in places like the Amazon or North Sentinel Island, where we have, already, passed laws to leave those people alone for various reasons, including preserving culture and not exposing them to diseases. Who knows how many other reasons there might be to leave uncontacted alien civilizations alone that haven't even occurred to us yet.

18:54 I LOVE Isaac, but I really don't think his _"odds of an individual atom ending up as part of a human"_ analogy really holds up here. For example, considering that stars like our sun tie up 99% of the mass of their solar systems, and the planets and moons tie up most of the remaining 1%, what are the odds that a random individual atom ends up as part of an asteroid or comet? Obviously, the odds are very, very, VERY low. Much worse than lottery odds. But does that mean that asteroids and comets are insanely rare and unlikely to exist in the universe? Of course not. There's millions and millions of them in every solar system. I just don't think this is an accurate way of estimating the probability that something will exist in the universe.

Maybe I’m missing an episode, but at some point you mentioned that novas were significantly more common in the universe than they are now which implies it would have been more common for mass scouring of planets to occur. There are stages to stellar formation. Early stars were all hydrogen and helium and nothing else except maybe some hydrogen jupiters. Then there’s 2nd generation star formation that could have had other elements. My understanding is that we’re at 3rd generation now or something (and maybe that’s a simplistic way of looking at it), but the idea is that our star was formed due to the bow shock of a 2nd generation sta going supernova. How far back could we reasonably expect an intelligent species to have evolved? Not 12 billion years but 4 billion? How many solar systems had the composition needed to support carbon based life 4 billion years ago? 6 billion? 3 billion? 2 billion? Where on that 1 year earth calendar could others have reasonably existed and not expected to get wiped out by more frequent extinction events? If the Cambrian explosion is in October then are we talking July? January? Earlier?

It's very likely true for our galaxy IMO that we are alone here. I expect space faring alien civilizations are sufficiently rare that most galaxies do not have one. There would however likely be many times more alien civilizations that are either extinct or never expanded into space, which given the timespans involved and the dangers in the universe pretty much means also extinct. I suspect unicellular life is quite common in the galaxy. Multicellular life however is likely extremely rare given the frequency of extinction events. From those rare multicellular worlds, the number that generate intelligent life that survives their own propensity for self destruction will be vanishingly rare.

Kinda unrelated though, but... "When humanity survives itself, humanity will survive anything thrown at it" (my own quote unless someone said this before) Like, humanity, once it figures out the social, scientific, and moral problems we have, we can advance far beyond now, if we dont solve these problems in time before we cause ourselves to go extinct because of our own selves, we will go no where but down, even if we go up in tech for a few points on the chart for a time.

I think it would be good to also consider convergent evolution and think about this possibly being a universal concept, to see how this would play into increasing the odds of other intelligent life that can manipulate its environment such as we can, within this universe. I really enjoyed this Issac.
@boobah56432 жыл бұрын
Convergent evolution is a universal concept. The catch is that there is such a thing local maximums, so even if at an earlier stage endoskeletons aren't obviously better or worse than exo, once you have one or the other there's very little chance that evolution will swap to the other, as it immediately starts to maximize the advantages of whichever option it 'chose,' at which point the chosen one _does_ have an advantage.

The simple fact that the fabric of space can 'stretch' at a speed faster than light, should be enough evidence to show that travel faster than light will be possible at some distant future time. The problem with this statement is that it assumes that the human race will continue to exist and will continue to increase its knowledge about the universe as time proceeds.
@theOrionsarms2 жыл бұрын
Well, some of the the current theories says that space-time could stretch faster than light speed, but that could be wrong, and even if this is right according with the same theories energy that alow to stretch space-time fabric do not propagate in the space-time faster than light, so that doesn't prove anything.

I don't know why it's such a difficult thing to believe, looking at the facts and possibilities. 1. We're either alone in the universe or we aren't. If we are, then the answer is very simple. We're first. 2. If we're not alone, either every race in the universe came about at the same time or they didn't. If the first is true, then we're still technically the first but we're all tied for first place. 3. Do you see anyone else out there? No? Then us being first is the most plausible explanation.

With all the adjustments thought of for humanity I cannot help but think of a Section 31 idea I had for Star Trek Enterprise. At some point S31 looked at humanity and made a decision. We were not good enough. Not strong enough or smart enough or empathetic enough. And they make a decision to alter all humans. At the time it's just a few scattered Sol population groups so with warp and impulse drive not a difficult thing at all. This also explains why they make a law against it. Because a close enough look will show the adjustments
