I disagree, Stellaris represents a universe where this hypothesis is false. According to this hypothesis you are either grabby and entering into a mostly empty universe or you never exist because all the planets are already taken. In Stellaris your empires appear as newly evolved in the middle of the timelime (Precursors and Fallen empires before you, and Primitives after you). This suggests that all empires in Stellaris (past and future) are non-grabby. They do not pass Rule 1 and Rule 3 "Expanding outwards constantly for a long time, cosmologically" and it seems there is something which stops empires from expanding forever... but lets stay spoiler free shall we.

@@benbuckton5114 an interesting point, and a good one; indeed the grabby aliens hypothesis, at least in this video's interpretation, neglects the decline of grabby civilizations. In stellaris, the precursor aliens either go extinct, or become non-grabby (fallen empires). It also features an unrealistic world where you spawn in a relatively short timeframe of your conquering the universe (100-300 years ish), and implies a short decline (centuries at most). You can actually see grabby survivor bias in stellaris: if the fallen empires never became docile, they could easily dominate the galaxy . However, since they wait, the new aliens have ample opportunity to overcome and destroy them through grabby behavior or other stellaris cheese. Also, stellaris raises the question of bureaucracy; can all aliens expand infinitely, or is there a point at which they overextend and disintegrate due to their massive sprawl?

The biggest problem I have with the "grabby aliens" hypothesis is that it assumes interstellar civilizations would have resource desires and needs that directly conflict with our own. However this could be a flawed assumption for a number of reasons: If it's possible for a species to travel light years away in some fashion, then given how empty space is, it's unlikely that they're explicitly dependent on planets for resources. Planets are infrequent, have high gravity and other hazards that mean they take HUGE amounts of conventional energy and effort to deal with. Let's take water for example, which is the most essential substance for life we know of. Despite the fact that Earth has literal oceans of the stuff, for a space faring civilization it'd be far more efficient to mine planets and asteroids, or even simply harvest hydrogen and oxygen from nebulae etc., then to land on a planet massive enough to hold water and grab it from there. Even if we assume ultra advanced future tech makes it *easier* to harvest water from an earth-like planet then it is today...why wouldn't it be even easier and more efficient to still get water from those other sources? Additionally, it's plausible that microbiological life on any alien planets are a potential *extreme* hazard to any species that evolved on a different planet; because their mere metabolism might produce compounds that are highly-toxic to alien life from other planets. If there's not a credible, ultra-scientifically advanced way around this...then one would expect aliens to *actively avoid* at least any physical contact with other life-bearing worlds.

That's a decent thesis you have there. I'd really only have one note to offer: According to biologists, there is absolutely no reason we should assume a risk regarding alien pathogens because of how pathogens have to evolve, often in very inefficient and counterintuitive ways to infect their prey. Just looking at how complicated it is for a virus to be able to infect a particular cell, from a particular host, one can see how unlikely it is for a virus, that has never seen a species, to be ready and armed for infection. These complications even make disease less likely when it comes to more complicated infectious agents, like nematodes and parasitic worms that often require multiple host species to complete a life cycle.

The point of "being early" is that the aliens arriving on a potentially habitable planet arrive most likely even before life evolves there. Then they change that planet in some form. And yes, there is a question whether or not they would need to mine or extract resources from that planet if there are asteroids and other planets around. But for one thing, they'd be going at the expansion full-tilt so they would use exponentially replicating machines, and consume all the resources in a solar system. For another, they might construct a dyson sphere or something similar, stopping any life from evolving also.

@@Hannah-cb7wr This is somewhat plausible, but a lot less so than sci-fi authors would like it to be. If we assume CHON (carbon, hydrogen, oxygen, nitrogen) life, as we have on Earth, then the basic chemistry is all the same. You can imagine the biochemistry developing differently, but it still has to deal with the same chemical building blocks as we do, so convergent evolution is likely to make many chemicals have similar effects in practice (CHON aliens will not melt when you dump water on them, for example). More complex stuff, like DNA, is going to be entirely different of course, but it's not as if we're going to try and breed organisms from different biospheres with each other. If we suppose the aliens are not CHON, then you run into two basic problems: * Your chemistry has to be elaborate enough to support complex biochemical pathways, and perform at least most of the basic functions that we see in CHON organic chemistry. * Your chemistry has to involve elements that are relatively abundant in the local environment, which is probably at least _somewhat_ similar to abundance in the universe as a whole. CHON satisfies both of these requirements. Most proposed alternative biochemistries run afoul of one or both requirements. Ammonia-based and methane-based are somewhat plausible, but both of those are hypothesized to function at temperatures and/or pressures vastly different to those of Earth, so they're not going to land on Earth for the same reason that we're not going to land on Venus (yes, the sulfuric acid is a problem, but the temperature is a much more immediate problem).

Not all people who believe we are not alone assume the aliens are more advanced than us. I personally do not believe we are alone, but believe that the vast majority of extraterrestrial life is single celled or “animals” of limited intelligence or physical capacity to construct things. That is after all what we find on our own planet. I won’t deny the possibility of more advanced civilisations or that we are the most advanced, as all the calculations used to do so are so speculative as civilisation and the emergence of consciousness is difficult to quantify. However I do believe that to just assume we are likely the most advanced species in the universe is just as hubris as to believe the universe was created for us. It is possible, but to actually believe it takes an unjustifiable leap of faith.

You were born the day you were born for the same reason your parents happened to cross eyes for the first time, and the same reason the raindrop hit your right cheek and not your left one. It happened because the specific events that allowed it to happen were present. Then the dice were rolled, and you won. Saying we are early is assuming that there is some deadline we totally missed. I also think it’s flawed to think that being early is some kind of special status that is weird to have when it really isn’t. If 100 people were placed in separate rooms with a button placed in front of them and told, “you may press this button whenever you like,” and given the freedom to do so at the exact same time, inevitably, one of those hundred will be the first person to press the button. Sure, you can try to come up with reasons as to why they were first, but they were just as likely to be last as they wer to be first. Their status as “first person to press the button” does not make them special for doing so. They just happened to be the first one by chance. We could very well be of the first 1% of all advanced civilizations that will ever be born in the known universe, but I don’t see what the problem is with that because being in the last 50% instead still implies that there was a first 1%, so if it isn’t us, it’s going to be someone else. Swapping our place with another advanced civilization wouldn’t make us normal. It’d just make us later by relation alone. I think the best way to look at it is to see that there is a high chance we may be of the very first, but know that we could always be wrong.

You're right but i think your perspective is a bit off. There must ofcourse be someone who is the first, or early. But the probability that, if you take a random civilization, that that is the early one is still very low. If you take a random person out of the room then the possibility that they were the first to press the button is only 1%. The same goes for us. The probability that we are early is very small if there are going to be a lot of civilizations, its not impossible, just very unlikely. Thats why this theory is interesting because it makes it more probable.

The theory doesn't make it any more probable that it happened, it only offers a different calculation of how probable it is. Nothing about reality has changed no matter what theory you believe to be true. That's what I think Carlos was getting at. To use the button pushing example; imagine each contestant is locked in their respective room, and the only way they can leave the room is by pushing the button to unlock the door. Humanity is like a person that pushes the button and walks out the door, and then sees nobody. If all the information we have is that there are 100 people locked in their rooms with the button that unlocks the door and can press it at any time, there's a 1/100 chance that we were the first person to walk out of the room. That theory explains why we don't see any other people, but it's still only a 1/100 chance it happened under that theory. However, the "grabbiness" theory would be akin to a theory that once the first person presses their button, all the other buttons in the vicinity are disabled. This theory also explains why we don't see any other people, but given the theory it'd be near a 1/1 chance it happened. The video was explaining the grabbiness theory, and how under that theory it's much more likely that we wouldn't see any other civilizations. Just like the theory of the first button press disabling all other nearby buttons. I think what the video missed is how this fits within a framework of Bayesian thinking: the idea of taking the given evidence and weighting the probabilities of theories based on that evidence. Humanity pressed the button and walked out to see nobody; that much doesn't change. But given that as your evidence, what then do you decide to be a more likely theory? Put simply, the grabbiness theory doesn't make it more likely that we're early. Rather, our apparent earliness makes it more likely the grabbiness theory is correct.

I agree with the first part: that we in fact may just be early. I've thought about this before. But the issue I have with Grabby Aliens is that it necessitates the need for Grabby Aliens blazing through the Cosmos at breakneck speeds to colonize in order to explain why the window for life is narrow enough to make us look "normal". It seems to be obsessed with averaging our situation as humans. It creates a "future" event to retroactively explain our arrival in the cosmos. It's like they are looking at multiple Universes and explaining why this one has only early life. But there are no other Universes to look at. There is no other "Older Histories" to look at. All we know is that compared to the potential age of the universe (assuming we are correct about red dwarves and the stellar age of the Universe) we are early. That's all we know.

No it just means that we aren't special, non-grabby aliens like us can only exist in the early stages of the universe. Given that, it is not actually that unlikely that we, a non-grabby alien at the moment, exist early, because that is the only time we could exist. We aren't in the "past", these are just predictions of what will happen in the future. We are in the now. Being able to predict future events is pretty much orthogonal to the other things discussed.

You are correct. The notion of reasoning that we must be early because the future is much longer than the past is a tautology. We exist in the first 0.01% of the life of the universe, therefore we are early. It is both true and meaningless. That said, I am very much a proponent of "we are early" because, IMO, there has not been that much time for "advanced" civilizations to evolve. The gas cloud that became the earth and sun formed approximately 1/2 the age of the universe ago. Gas clouds that possessed enough complex elements to form life on a rocky planet had to form from a combination of fairly common nova and supernova events AND much less common hypernova events. The latter, in addition to being very rare, also require much longer, not because of the lifespans of the original stars, but because they had to be far enough apart that the second star was not destroyed by the first one going supernova, but not so far apart that they would not have collided by 7bn years ago. It takes a very long time for two bodies to bleed off enough momentum via gravitational waves to collide. In other words, the clock did not start for the development of "advanced" civilizations until some amount of time passed between the big bang and about 6-7bn years ago when our home dust cloud formed. We took about 6-7bn years from when that formed, and it is unlikely that anyone got more than a couple bn years head start on us. Further, if they did, they may have been working from a less enriched cloud, so may be developing more slowly.

Perhaps causing us to become beasts of burden or livestock of a sort. It's not that the universe is anthropic, but that we literally could not develop outside of this narrow period of time. Consider the other species of hominids and how they were -slaughtered- outcompeted by homo sapiens.

This would probably mean that they'd have either colonized most surrounding systems with obvious waste heat signatures and other things or have colonized our own solar system. Why would aliens colonize the galaxy and just happen to skip out on our bubble? If there are grabby aliens they would've colonized our entire galaxy including the moon. I could, although, see earth being left as a nature preserve just due to the sheer quantity of planets. I also don't see any reason they'd hide themselves from us (which would be very hard because of waste heat.)

Why are we early? ... _someone,_ who _just happens to be early_ is going to find themselves wondering why they're so early, assume they're not early because of how improbable that is, or assume they're something fishy going on, some problem to solve -- and then try to infer a bunch of stuff from their apparent earliness. It's entirely possible we're early because we happen to be early. The universe looks exactly as you would expect it to look to a civilization that was very improbably early.

Other things to consider are the great filters you mentioned before. Humanity being as "grabby" as it is might (and already kinda is) result in a backfire where we start depleting resources and expanding way faster than our host planet can handle, eventually leading to a war on resources which escalates into a nuclear apocalypse, another possibility is a carington-like event happening every few often that pretty much presses a reset button on a civilization's technology, theres also how hard interstellar travel is, the creation of a superweapon or technology that leads to the total destruction of a species, so on. Maybe actual advanced grabby civilizations that succeed are extremely rare, so rare that the nearest one is multiple galaxies away. As for solar sails while they are useful they kinda require either a massive laser or being extremely close to a star for propulsion, they could maybe be used partially but I feel that fusion/antimatter technology will also be a big thing when it comes interstellar travel.

I mean, any speculation about future technology runs into a serious roadblock, or set of roadblocks: That we can't predict the next Revolutionary Innovation. To a scientist prior to Agriculture the idea of a tribe of tens of thousands of people settling down in one area and not immediately starving to death would have required a land of incredibly implausible fertility. To a scientist prior to Industrialization the idea of one brand of clothing being so uniformly, cheaply, and easily replicated and shipped worldwide as to be worn by commoners in Europe and Indonesia and America alike would've required a literal deity of sewing and the intervention of several deities of the sea, just to produce and ship. To a scientist prior to Flight the idea of humans flying seemed totally unreachable, a pipedream for the philosophers with more optimism than practicality. It makes it very difficult to predict future technology, because a lot of the time these Revolutions aren't born of the typical plodding forward that fills out behind them and is propagated by everyone with a doctorate - they're crazy, unpredictable leaps forward by total madmen who happen to reach for the stars and snag one. We can't entirely depend on interstellar travel being impractical. For all we know, the next revolution is mathematical, and the redefinition of space-time under this new mathematical paradigm allows us to use exceptionally low amounts of energy to warp space-time directly and permanently. Suddenly we can brute-force an event horizon, generate artificial gravity, and use alcubierre drives to zip from system to system in half a minute. I think this is the real killer for the Great Filter hypothesis. I'm sure some species do indeed off themselves early on - but by the same token, many won't. And with the unpredictability of innovation, I don't think it's smart to discount anything for being "inefficient". It's probably not even smart to discount the impossible, but that at least is more forgiving. The inefficient regularly becomes the efficient, historically, and I expect to see that trend continue into the future.

When discussing Fermi's Paradox and its related ideas, no one ever seems to consider the possibility that significant and visible changes are not possible. Indeed, the very existence of the Fermi Paradox seems to be extremely strong evidence that things like Dyson spheres are actually impossible. This idea about the likelihood of developing advanced civilization so early is interesting, but it can really be simplified: Given the current apparent age of the universe, 13.8 billion years, why does it appear that the universe will continue to exist for so much longer than its current age. We don't need hard steps or planet lifetimes, just the observation of the age of the universe compared to our models for how long stars and planets last (many times the current age of the universe). Grabby Aliens seem like a terrible solution. My view is that most habitable planets are inhabited, and that a significant number have civilizations on them, just not much more advanced than our own, because interstellar travel is harder than people think, and because visible changes to solar systems are completely technologically impossible for everyone everywhere.

Also, they always take the paradox as a given. It isn't. We are practically blind in terms of our ability to observe another intelligent species. If FTL travel is impossible, and we believe more and more every day that it is, then the odds are overwhelmingly high that we just haven't been observing long enough or wide enough.

Because of how information travels, it's not old data. It's current to our time frame. If FTL travel is impossible, then there's no way for that data to be 'old,' because there's no possible way for anything from that planet to reach us until the number of years it takes for information to travel passes. Basically, it's not old data because information has a travel speed; the information you observe right now *is* current. It takes time to travel somewhere and affect it (light traveling a distance is considered affecting things, gravity waves are the same, etc), therefore what we observe *is* current.

With all due respect, this conclusion seem to be taking the thesis for the hypothesis. Grabby Alien would indeed lead to most emerging civilisation to have been early, but if we are indeed early, then the grabby Aliens haven't emerged yet and are only speculative. You take Grabby alien as an explanation as why being early is the norm and concluding that we are ourself Early, but haven't proved that Grabby Alien will come up later in the future But you also seem to imply (unless I am mistaken) that us being early show that there will be early Alien in the future. It's one leading to the conclusion of the other or the other way around, but if you use each one to justify each other, then the whole demonstration doesn't stand on any leg. It also doesn't affect the odds that factor in how early we are. Meaning that even if Grabby alien never come to be and if we are indeed early, it doesn't affect the probability of our existence coming to be. Also, lastly, I don't appreciate how any civilisation following the same reasoning, would conclude that they have to become grabby alien before other Grabby Alien crush their emergence.

i disagree; i think the theory of grabby aliens can be taken as a 'proof of earliness' certificate. we know that we don't see a sky full of grabby aliens (or ourselves), and according to the theory, the emergence of grabby aliens precludes the independent emergence of other aliens, hence we must have emerged before grabby aliens. even assuming the transition from advanced civilization to grabby is a hard step in and of itself, that wouldn't significantly change how early humanity's emergence is, as the graphs demonstrate. our earliness/non grubbiness is still unlikely, that's inevitable, but what this theory demonstrates is that we are an average example of an unlikely thing, which is a better explanation than that we are simply unlikely. regarding the self fulfilling prophecy, i think your reading is wrong. this isn't a question of moral conclusions, this is purely a question of chance. a species which is not grabby will not significantly expand, and will be very hard to spot. a grabby species will expand, and will be very easy to spot. a species doesn't 'have to' conclude to become grabby, it's just that once even a single one does, we will see them everywhere. we don't, and so we must have emerged early, before a grabby species has really got going. imagine if another species on earth made a go at becoming sapient. because we have already become 'grabby' on earth, no matter where they tried to emerge, they would see humans everywhere.

The reason for this is because no species is smart enough to reach interstellar levels of technology and are stuck at the type 0.3-0.6 civilisation level, so humanity decides to cheat by creating beacons that broadcasts packs of information containing type 1 civilisation levels of interstellar technology throughout the universe along with FTL and then go into hiding or hermitage for lols so they can watch to see what they do. Hundreds of species finally enter space and find a galaxy spanning empire that is nothing but a ghost town of empty worlds belonging to these precursors with tech too advanced for them to understand or replicate. The comedy comes from the aliens wondering what happened to these precursors, figuring out our technology, and the reactions, ideas and beliefs towards humanity branch species and the other aliens that form. Every now and then humanity teases the aliens by hinting at their presence then goes back into hiding to watch the show.

On one hand, grabby aliens make us look less special by explaining why there isn't a bunch of other types of aliens out there, but on the other hand it makes us look MORE special by being one of the few races that slipped through their hands and were allowed to evolve naturally on a planet of our own.

It's simple long tail. The vast majority of rational species may not be grabby, or may never develop science and technology to ever have a chance of becoming grabby. But if there's a small chance for one of them to become grabby, then a big enough number of them almost guarantees one of them _will_ become grabby as the probability of that happening grows assimptotically toward 1. And that one, whenever and wherever it arises, will then capture everything in their future light cone.

Guessing that If a specie is capable of reaching an alien world in order to take its resources and colonize it, it can probably sterilize it in preparation of Terraforming. Making the previous life forms go extinct and in the end it's as if they were never there.

@@SeraphimFelis Not strictly true. There are many other explanations to the Fermi paradox. The ultimate resource problem for an advanced species would not be space, materials, or energy, but time. The heat death of the universe puts a hard limit on time for biology. A sufficiently advanced race might "move inward" to a simulated reality that can be progressively operated at faster and faster speed, giving them much greater time, and perhaps time enough to transcend the heat death limit. Another explanation is that expansion is not actually cost effective. We know that there is more mineral resources in our own asteroid belt than humanity could use at its most wasteful for millenia. And we only get more efficient in material use. It is entirely possible that trying to send any small number of ourselves to another planet would be a tiny drop in the bucket of resource gain compared to maximizing our use or own solar system. And in the millennia following, we might advance our science so far that moving to another planet would be a needless concept.

I also have a feeling that this whole thing might be a bit too inaccurate, the concept of planet lifetime on that graph kinda confuses me, even on video he stated that shorter lived planets make us more rare and early, while the graph shows the reverse stating that life on those longer lived planets is more early, probably to understand this I would need to read that paper, unless someone can explain to me that in short also 10% still seems like a lot unless I don't get the scale, maybe instead of lifetime of a planet, it would be better to use age of universe + number of planets/stars that exist in certain category or something like that on 3d graph... the more I think of this the more I feel motivated to read this whole paper unless it will be too long and too big brain for me

My basic gripe with all ideas like this is the belief that a species could achieve interstellar colonization while retaining the competitive traits acquired through evolution. We already know that strong genetic engineering is required for any long range space travel, and absolutely essential for colonization of another planet. We are on the cusp of our genetic age already, long before serious space travel. If we ever do send ourselves to another planet, believe that they will not really be modern day "us." This would likely hold true for any space fairing race.

I'd guess becoming non-grabby is a possibility - much the same way in human civilizations, when we're just getting going and still striving/struggling, we have a lot of children, and expand our population. The more advanced a civ gets, the fewer children it has, even to the point of a birth rate that isn't population-sustaining anymore. Could happen on a larger galactic scale, too.

I think what this theory doesn't take into account is the power of evolution, it assumes grabby aliens will remain the same over time. For example, as a species becomes grabby and expands outwards into the universe they would, over time, evolve to different conditions and become less and less like their grabby ancestors. After billions of years, the grabby aliens in different parts of the universe would be almost unrecognizable from each other. The logical conclusion to this is that at some point in the far future all habitable planets are occupied by different grabby alien species some that look similar and some that are vastly different (but all arose from a single origin). This kind of mirrors how all life on earth began with one single self replicating entity that evolved to all the biodiversity we see today. Every living thing on earth is related but we are now all vastly different organisms.... and that's only after ~0.5 billion years.... could you imagine 1000 billion and a whole universe to grow into? It doesn't really matter if humans are early or not, if we expand to the universe our descendants will be so different from us they may as well be completely unrelated at that point.
Will we grab the universe? Grabby aliens predictions.
