    What if the great filter is simply a technological impossibility? What if, there are plenty of civilizations out there, but all are thousands/millions of light years away, so communication is literally impossible. We have never found anything (to my knowledge) that surpasses the speed of light, and the speed of light is relatively slow on the galactic scale.
    The "great filter" may just mean that species' can never and will never travel to other stars, not because they are annihilated but because the technology required to do so would have to be so advanced it may as well be impossible.

      I believe the truth is somewhere inbetween, escaping solar system may be impossible, but how long would it take humans to develop a system that destroys us, trying to achieve the impossible, as in escaping solar system.
      If something of that sort were to be impossible, it would eventually kill us. even if not by our own hand, our star would eventually do that for us

    One thing I find interesting is that we humans always base their perception of life forms by looking in a mirror, watching our own world and the building blocks of it. What if other life forms are formed differently than the ones we know of? What if life can be gas-based instead of carbon-based with cellular walls? What if Jupiter has life but we just don't know what that kind of life form that actually is? We don't understand it, we cannot perceive it, and we cannot communicate with it. And it's the same for them. They cannot perceive us, they cannot communicate with us... It's an interesting thought :)

      Exactly what I always say, when it comes to intergalactic life we only base it on our perception on what life is, and we only deem planets habitable based on our requirements for us ,carbon based life, to survive on them, if life formed on other planets they would evolve to adapt to their specific planets conditions, not our idea of perfect conditions, hell you could have life living on our sun and we'd never know as we physically can't look at it let alone visit it

      @Philip In general or for the context of life outside of earth? Because we already use studies of other species biology in advancing our own technology. Several species on Earth have seemingly straight up magical natural biologies. Honestly if you REALLY want alien life look up information of the species living in the oceans (especially deeper depths (most of which still haven’t been explored due to pressure)).

    I never understand why there can’t be more than one great filters. Even if one is behind us there still could be one ahead of us. Even if we are the first ones to encounter it. Being the only ones that made it that far does not provide any assurance for the future.

      That's addressed in the video. They're called obstacles or "filters" if you will. The idea of a "Great Filter" (the whole point of the video) is that there is a specific hypothetical filter that all life must pass or be doomed.

    The step on this staircase that took the longest on earth (and thus is a more likely filter) was the step from single celled to multi-celled organisms. There were single celled organism on earth less than a billion years after the planet formed (possibly before that.) But multi-cellular life only showed up about 600 million years ago. So there were around 3 billion years with only single-celled life...and two billion of that had eukaryotic single-celled organisms.
    Here's hoping we're through that filter. Though, my guess is that there's more than one :-)

      I think you're right about the timeframe but wrong about the actual filter.
      An interesting thing about the great oxygenation event (which predated and enabled the development of multicelular life) is that it's a strong candidate for being The Great Filter.
      Physics is physics, and therefore organic chemistry is organic chemistry. Therefore the early life on any planet is going to have a chance to stumble onto photosynthesis.
      The thing is the early pre-photosynthesis Earth was being kept warm by methane, but that had to be coming from somewhere. Quite possibly early single cell bacteria itself. Once oxygen production really got going and oxygen started leaking out of the oceans into the atmosphere it bound up all that methane into other compounds and caused a near global ice age. That presents early life with two different ticking time bombs.
      If life waits too long to start producing oxygen that thickening blanket of methane eventually turns Earth into Venus. Broils the planet and kills everything.
      On the other side if life figures out that trick too early then the resulting ice age is even worse, and if life is completely wiped out then when volcanic and solar activity melts things again what's left isn't the same primordial soup because of all the oxygen reacting to things. The initial state of free organic molecules is quite possibly a one-time opportunity.
      We threaded a needle that might be a _lot_ narrower than we realize.

      @Lego S True, but vision is only one way that humans in our realm perceive things. Perhaps an alien (to us at least) perceives, and experiences things dimensiinally, or through some other construct, ie: time, fluidics, sound vibrative, electrical impulse disruptions, or gaseous densities, etc...
      That is what the word, "alien" means doesn't it? Different from what we are accustomed to. Who's to say that they haven't already colonized here, on some other dimensional plane on this planet 1000's of years ago. And, that humans cannot access or perceive of it because of our lack of some organ, or ability to perceive or sense them. It would explain a lot of weird stuff that has happened in our past, (technologies, sightings, architectures, fosils) and even today.
      Not visitors from another world, but eartling's from another dimension that might be more advanced technologically.
      Or not.
      Maybe all the galactic civilizations had a meeting and said, "Don't f*** with Earth, those bastard's got their own problems!

    I have a theory: the great filter is space travel. Maybe all the civilizations thrived until their own sun exploded like ours at some point. But.. that is because all the stars were so far away from each other. At a time when the stars werent this far away from each other their existed intergalactic civilizations. But now the question is… how dod those end??

    Its basically two equally depressing realities. Either we find horrifying traces of intelligent civilization beyond ours, that all points to our doom a.k.a. the filter. Or the filter does not exist/we're the only ones that passed it, meaning we're alone, in the void devoured by emptiness.

      Considering the odds of the development of life, it has had trillions of opportunities to occur with the entire periodic table to build chains of living tissue from. The Goldilocks Zone is nearly useless considering the only lifeforms that could survive in them would likely be carbon based. Taking this into consideration, it is highly possible that there are in fact other lifeforms somewhere in the galaxy, and almost definitely other lifeforms in the universe. It is horrifying, yet fascinating.

    Another rather outlandish possibility as to why we haven't presently discovered alien life is that we may very well be a monitored species. Not to the extent and self importance of the scientologists doctrine but more like how we humans observe how other animal species structure themselves. In their case, its more along the lines of seeing how a rapidly developing intelligent species functions and behaves to certian challenges presented by the natural progression of their societies. In which they are neither beneficial or malevolent but simply neutral observers. It could be that we were noticed a long time ago and a hypothetical advanced species saw us as an opportunity to gain further insight into the development of Intelligent life as a possible way to trace back or understand lost information of their history. Although this hypothesis was drafted at 2:45 in the morning so idk

    The most difficult step, on my thoughts, is to be an interplanetary civilization. You need far more than human resources and collaboration to colonize other planets, you need to build a lot of things that only was possible with an organized way to store knowledge AKA cience. Too many conditions to reach that point (being able to reach other planets). After that, if they spend enought time as a biplanetary civilization, soon or later the new envirement would make human people adapt themselfs to different conditions than on Earth. Rapidly it could become 2 civilization of different species lol. So, the great filter is ahead of us, but near to cross! So, yeah, we could be the first on the last 13 bilion years, maybe its a fair propotion.
    "13 bilion years to a high advanced inteligence spread out from its planet and than trigger a galaxy empire domination scenario of StarWars" - Its engouth time to make something ultra rare possible to happen, doesnt it?

      @Kris Olson That’s assuming they’re capable of travel across the endless expanse of the universe. It is entirely likely there’s life outside of earth (more or less advanced than us), but the odds that either of us will ever reach each other is much less likely. A species only has a finite amount of time to develop before life on their planet becomes inhabitable due to changing conditions on said planet and their sun. But then let’s say the species survives past its planet (colonizing other nearby habitable ones or living in space station), again its entirely possible they’ll never gain the ability to travel the distance needed to reach us.

    I think you're thinking of this far too negatively, and are focusing too much on colonizing other planets. For example, if we DO find dead alien civilizations, its likely that we can learn from their mistakes to avoid our own demise. Also, colonizing new planets might be more of an energy/resource drain than simply using uninhabited planets as resource mines instead of destroying earth for it (this ignores population growth, but proper education on how daunting it is to be a parent/healthcare could theoretically help with that). Really I'd be more worried about the problems with finding an alien bacterium that tries to eat us in its stupidity and creates a global pandemic we have no means of defending against bc the chemical composition is unlike our own organic molecules

      Actually, the great filter refers to that "event" that it's practically 100% impossible to overcome. But it doesn't imply that said event can't be "multiple things at the same time".
      So, even if there's actually multiple filters, the categorization or group of those filters is what we call "the great filter".

      @rod lopes no because we wouldn't be able to see any of them at any stage. We can't even say if there's life on Europa. let alone say if there's animals scurrying around a tiny black dot on a photo of the nearest exoplanets. Every image you think you've seen of an exoplanet is an ass pulled artists rendering, the only thing we can even be remotely sure about is the mass of the those objects. Lit up cities, satellites, space ships, even a dyson swarm would all be too small to detect from earth even if we were looking right at them, and if a species were advanced enough to break or bypass the speed of light, our eyes and ears would have absolutely nothing to go on. We need to drastically advance our observational technology before we could even begin to say that there isn't an abundance of intelligent life right in our backyard.

Maybe that's the lesson of Atlantis.

    If the great filter is in front of us that means many forms of life develop into an intelligent form which organizes and colonizes. This means they would start to do this and given how "little" advancing you need to do in order to make quite a lot of noise in the galaxy I would wager that we would probably find evidence of this without a huge amount of effort.
    If the filter is BEHIND us, it means very few forms of life develop into an intelligent form which organizes and thus very, very few examples of civilizations make it to anything near planet-wide coordination. So logically it is more likely the "great filter", if there is one, is actually BEHIND us and not in front of us.

    Considering that we have no clue how life originated and in a situation like Earth where life did happen, there is still only one somewhat intelligent species (us) out of every species that has ever existed (which is estimated to be ~10 million). This already indicates that we are an anomaly. That - as mentioned in the video - intelligence isn't that great in terms of evolution.
    Now we may consider how many habitable planets are in The Milky Way, which is estimated at ~300 million, which really isn't that many considering the scope of The Milky Way.
    So 1 species out of 10 million with a somewhat small chance of exploring just a fraction of a galaxy with only 300 million habitable planets. And that's not even considering the likelihood of life spawning in the first place, which we can't really calculate. With these numbers it's very likely that the filter is behind us, and anyone else that has passed that same filter is just too far away and the ones within reach are simply behind us in development.

      @Sander Spijkers not every planet of all infinite planets is inhabited, so the number of inhabited planets is finite. That claim is a fallacy.
      Let's say we number all the planets in the universe. (By distance from earth for example) Then let's imagine that every planet with an odd numbering is inhabited.
      Every odd number on the number line is now connected to an inhabited planet. There are infinite odd numbers, so in this case there are also an infinite number of inhabited planets, while still not every one of the infinite planets is inhabited (all the even numbered ones aren't). Contradicting your statement.
      More mathematically formal. There exist subsets of infinite sets that themselves have an infinite cardinality. It even is the case that almost all of the subsets you could possibly form out of your original infinite set, are infinite sets themselves.

    I have a theory, I saw a different documentary to this one ages ago, it was very scientific and told me that the 2 most versatile molecules in the universe are carbon and silicon, because they can both form complicated structures. So in theory, if there was a planet somewhere that has lots of silicon, and other molecules, there maybe a combination of molecules for a silicon based life form, and if that was to happen, or if it has happened, that life form would most likely be the most successful type of space explorers possible. Our own technology has gone through the roof since the moon landings, and it’s all thanks to silicon chips, and right now we are on the cusp of creating a silicon based life form. What if it’s not a coincidence? What if our constant hunger for newer better technology blinded us to the fact we were given this tech in the first place, and we are being steered towards creating an artificially intelligent species that they could turn on us at anytime. Am I completely nuts?

    This video explains that there must be a 'Great Filter' because we have not yet observed life in our galaxy. In Scenario 2, it is suggested that the discovery of extraterrestrial life would mean that the filter is ahead of us. However, would this discovery mean that there is no 'Great Filter,' since the theory comes about only from the lack of such a discovery?

      I'm late to the party but no one's pointed out the obvious yet. We live in a BIIIIG fucking galaxy with lots of empty space between. Every one assumes that if a species had the ability to travel between stars they would set up a galactic empire for giggles and shits. This theory completely ignores the fact that such a venture would be extremely expensive, dangerous, and not the kind of thing you do with out a good reason.
      Then you figure that within our solar system alone we probably have enough room and resources to hold us over for the next 50,000 years. Beyond that the nearest 5 or 10 stars are guarantee to be uninhabited, and it's going to be a very long time before we even need to go that far. If we do reach that point we might fire ff a few exploration probes, or send some brave souls on a quest to make first contact. However chances are what we do find at that point is either going to be so far behind us that they remain nothing more than a curiosity, or sufficiently ahead of us that they can either avoid our sensors, or destroy what ever we send at them.
      Either way they wind up being to far away to be of any serous importance, and aside from the potential for amusing dialog, are only worth passively observing.
      Hell for all we know there's a species of aliens that have a small observation post 15 systems away that's recording us with deep space probes. That might actually be the reason no one considers this option, if we're alone in the universe we're special, if the aliens come to conquer us we have something they want, but if they're just sitting at their home planet watching us on their equivalent of the discovery channel to see if we do anything interesting that's just depressing.

      Your comment adds a lot to the discussion. So, basically if we do find this, "Gallactic Empire" that everyone is mentioning in the reply then yes. There is NO great Filter, but rather just a small speed bump (if anything). We still had better not find Alien Life though. Because the only possibility that we have of there not being a Great Filter in our Future and Alien Life existing, is as others have mentioned a Galactic Empire existing. If one exists, then yeah, we get it, no great Filter. But we're doomed because this galactic empire may not show any mercy.

    Given the fact how long it took us to evolve from hunter-gatherers to where we are today and given that this rate evolution transformed from linear extremly slow to extremly fast exponential evolution of technology and that we're just 1 pixel of human existence and we're already so close to destroying ourselves => I'd say numerous civilizations emerged and existed and now exists but destroys itself extremely fast. Due to the fact that oru existence on the time scale of universe is soo tiny - it makes improbable for us to coincide with the existence of another civilisation nearby. But many many existed and will exist, but all die out. Maybe because of this technological advancement.

    I think we've past most of the steps but there is one that concerns me. I feel humans as they are now are unlikely to pass the inability to act beyond impulse(primitive design). We are capable of greater intelligence but are still driven by old behaviors. The other line I see standing out is the difficulty of surviving all the varied conditions in space or places different than earth. To be able to get to other earth like planets we will probably have to inhabit non earth like planets and just the effects of low gravity in travel or on mars may be enough to stop the human body as is from continuing. We may need to re-engineer our form or have many systems that can simulate as close as possible our earth like conditions. Both of those seem like massive conditions to me. If we achieve those I imagine humans(or whatever we become) can and will inhabit the galaxy. Assuming we don't face a disaster before the opportunity to make those changes comes or run into some unknown. I honestly think there probably is life out there maybe similar to ours or a step ahead maybe behind and we just can't see because the light hasn't reached us yet. Just like we are well because they probably can't see us. They might be looking at mammoths or dinosaurs If they even see earth.

    It could also be the great filter is extinction in the right places. That life tends toward megafauna like dinosaurs- combining with the "cleverness is an expensive investment with no obvious payoff" note- and that in Goldilocks planets that haven't suffered an external force causing an extinction event at exactly the right time, mammals (or any animal) evolving more dedicated brains simply never happens because they're too busy being eaten by the megafauna that invested into pure brawn. It took us and our ancestral species a while to figure out that rocks and sharpened sticks were good tools, and they had a lot of trouble surviving until then.

    There is one theory I recall reading about, and it basically lays out that violence is one of the requirements to advance as a species, and the willingness to commit genocide is another prerequisite.
    Basically the theory supposes that a species will face a constant drain on their resources and ability to survive unless it is capable of defending itself against predators, that much is obvious. But then comes the second prerequisite, the willingness to commit genocide, to wipe out completely another tribe or species from an area. Out of all species, only 2% of life on Earth has demonstrated a willingness to completely wipe out another species from an area. Most will drive off their competitors, claim the resources for their own, and likely be driven off in turn. The only species to actually commit genocide willingly that we have observed are Humans, and other primates (as well as Meer Cats, but those are an outlier.) Of our primate compatriots, only humans and Chimpanzees (specifically a small number of sects in Africa and India) have shown the willingness to outright commit the genocide of another animal, pack or Tribe effectively unprovoked.
    The author explains it as a tribe of early humans living in proximity to a pride of lions. The lions will not attack the fully grown humans, as they present a risk to the lions, but the infants, children, and early teens present a much lower risk for the lions to hunt. The theory would be that in the majority of species, they would only attempt to drive the lions off, maybe killing 1-2 of them if they can, but otherwise leaving the rest to live. Thus in that way, until the lions are eradicated or driven completely from the area, they will continue to hunt the infants and children. As life is not omnipotent, eventually the lions will succeed, and they will learn methods to succeed, resulting in a dwindling population as bloodlines are cut, fewer and fewer infants and children reach the age to have children of their own, and eventually the tribe stalls, and is wiped out with a whimper.
    Thus comparatively humans, thanks to our violent nature and willingness, if not sometimes eagerness, to completely destroy another species likely would have formed a hunting party or war party with the express goal of slaughtering the pride of lions, cubs included, to ensure the continued survival of the tribe. Humans would willingly do this over and over and over again to keep the tribe and it's future safe.
    So as far as being a great filter, at least as of right now, the only animals we see advancing technologically are willing to completely scoure and area of threats, killing everything, even if it is not required for food, so long as the animal or group pose a threat to the tribe of pack. As only 2% of life on Earth displays such a tendency and willingness, it would not be too far fetched to believe it maybe a prerequisite for other life.
    It also could easily be flipped on it's head to show that if there was Alien life out there capable of contacting us, the reason they haven't is because we are that micro minority of life that would willingly and knowingly start committing the genocide of other species just because.

  • Brian Edwards

    I have a few quibbles: Cooked food aside, humans needed fire to keep warm in the ice age. No fire, no science because just about all of technology requires fire (glass, ceramics, metallurgy...). Ectothermic and aquatic intelligences would probably never invent the knowledge of how to make fire.
    Also space is big. I think galactic civilisations are actually not possible because the distances involved make balkanisation in the extreme almost certain. FTL drives are still a pipe dream and may be impossible so we may have to accept that the speed of light will always limit interplanetary, let alone interstellar communications but we might colonise by "rock hopping" from one landfall (asteroid, mini planet, enclosed habitat, rogue interstellar planet...) to another making each cluster of "people" (space will change us from what we are now) a link in a chain and it only takes one link to fail to create "islands".

    Gah! It's frustrating to know that the answer to so many questions we have about the universe will never be answered in my lifetime! If there's an afterlife, I hope I can just spectate whatever goes down afterwards lol

      @Juan Gonzalez maybe we aren't our cells, or our body but they are our vesels, what if our conciousness is the energy, that cannot be destroyed and only changes forms?
      What if we die and when we wake up we are something else, a star, a meteorite, a planet? Maybe we just return back to the earth and we'll become one with it?

      @Imperial Courier in one of Kurzegasgt's videos they said "close your eyes, count to one. That's how long eternity feels" maybe dying is just like that, just like before we were born, it feels like it happened instantly but it wasn't.
      Maybe we will one day close our eyes and wake up in the future, somewhere.

    The Day the Earth Stood Still makes me think more about the option that there IS intelligent life in the cosmos. It's just incredibly hard for life AS WE KNOW IT (Carbon based) to progress and succeed, and because of the distance of space - we'll likely not encounter them unless our planet is so rare and so full of complex life; our destructive ways will bring them to cleanse the planet to continue all life except humans.

    As the video discussed going planet to planet, then star to star, it occurred to me that they stopped short of the next logical step - galaxy to galaxy. Lot of galaxies out there, and we know very little about any of them. Could be that civilizations at that level just haven't gotten to our galaxy yet.

    At the end of the video you imply that there is only one filter depending if life is common or not. But even if humans do or do not discover extra terrestrial life, they can still destroy themselves with the technology filter
    I don't see how the extra terrestrial life mean that the technological filter not work anymore
    Tho apart from that, another amazing kurz video :)

    I could buy the filter being behind us. There's so many factors and lucky breaks that got us here. Especially the ones covered in the video. But even then just the idea that an intelligent race can evolve could be low chance. If not for events on Earth playing out as they did there may not have been hope for humanity to survive long enough. For a good long while the dinosaurs were most dominant and they probably weren't on the path to developing intelligence. It wasn't necessary for them to get where they were.
    We may really just be that lucky.

    What if the filter is just space travel? There could be many happy, thriving solar systems where the species lives on all the planets in that solar system, but there isn't a galactic civilisation because stars are just stupidly far away from each other. That's a positive idea worth mentioning, surely.

      @Dandy Jiggins if you think about how old the universe is, a million years is just a blink of an eye, our civilization is only like 300k years old in the grand scheme of things it is very likely that civilizations can reach up to a type 7 civilization aka a creator civilization and has access ti quantum teleporting where you have the ability to fold reality for example imagine us in a 2 dimensional plane and 4 dimensional beings in a 3 dimensional plane if our 2 dimensional plane is for example a piece of paper if the civilization is advanced enough they can fold reality and poke a hole through reality, but of course this will take a immense amount of energy to do but if a civilization is advanced enough that amount of energy will be like the amount of energy it takes to turn on a light bulb, therefore making it incredibly possible but because of the great filter this is imposibble

    I just think it's impossible for mass groups of very complex creatures to responsibly manage the power they wield. We are already playing with dozens of technologies that could each ruin the whole planet, and there isnt a struggle to stop any of it. The fact that we want to colonize everything is the issue that will prevent it.

    What if the filter is simply an elevated level of happiness and contentment?
    Let's take a look at the basics: if "we" survived Earth, we've existed almost 10x longer than horseshoe crabs and we would have probably survived meteor impacts on the scale of a nuclear winter and stabilized the atmosphere in an unprecedented way. Plus Earth tends to get unbalanced from time to time - Snowball Earth is a good example to look at.
    Even the sense of "we" disappears with time. I would not understand people speaking my native language 500 years ago. And even in less than 5 generations we become complete strangers.
    So, these thoughts are more like feathers of birds. We produce our "feathers" because we have such instincts. We have an instinct to explore. But as we explore, exploration itself will become more and more meaningless but will require more and more investment - yet again a great filter.
    When exploration becomes meaningless - and it already sort-of has become - maybe we'll find toy-frameworks where we can explore more, or the same things again, just like how we've built yards for dogs or kindergarden for children.
    We just learn how to better manage ourselves, how to better satisfy our needs.
    Also, our mind is a great filter.
    Probably we *are* the great filter itself, living in *our* great filter.

    Here’s my theory: life is quite rare to begin with, but language is the true great filter. We have not seen any Inter-galactic species because it so incredibly rare to develop language. There is other life, however not common in the slightest, meaning we most likely won’t be able to see it

    this must also be related to the Kardashev scale where it stops at type 6, considering type 7. a god civilization which is what Christianity, Greek, roman, Mayan,, etc. mythologies are based off of, maybe there are type 7 civilizations that created us, they have the ability to create, and also destroy life
