Playing with the variables, there were LOTS of options where life popped up rather frequently, but either died off or just 'drifted away' too quickly for any potential contact without FTL. A lot of assumptions went into that, since we know so little about the variables in question, but still a fascinating listen.

Faster than light travel is impossible and breaks causality. You can travel somewhere like andromeda in only 15 years without going at the speed of light just going at 99.99999999% the speed of light the only problem is time dilation takes place so in your space ship 15 years goes by but on earth 25 million years goes by. Because of how spacetime works time travel is impossible. And if you were travelling at the speed required under the speed of light before even reaching 80% of light speed the radiation would be hitting you at such a speed that it would damage your DNA and would blow up your ship. Thus faster than light travel is impossible l.

I would love to see a realistic breakdown of the timeline in this supposed Fermi Paradox, and I've only done bits of it myself. Fermi said the universe was ancient, why aren't there aliens (VERY abridged)? But, for life to form, how 'ancient' is our universe really? What I mean is, for a 13.8 billion year old universe, how much of that timeframe could we feasibly expect life as we know it to form? Could there be aliens 13 billion years ago? VERY unlikely. From what I understand, it's unlikely that there were even rocky planets at all back then, much less carbon-rich planets with tons of heavy metals. But, really, how long does that actually take? How long did it take for the first stars that produced the REALLY heavy elements (Uranium and the like) to go super-nova and distribute those elements? Heck, I think Uranium may have needed neutron star collisions, right? How long did it take for that debris to form into planets around a new, younger start? Now, the other question, how common were those back then? Let's not assume that a planet with the right mix of elements formed in the Goldilox zone in one of the first 3 stars that it could have, and that life then formed on that first planet it was possible on. Let's assume there's some odds here, so odds go up as 'heavy metal rocky planets' become more common. Now what about star type? We orbit a relatively calm, large, warm star. Are those more common now than 8 billion years ago? Ultimately, my question is, should we be asking 'where are all the aliens in such an ancient universe' at all, but rather 'how'd we get here so early' or 'yeah, looks about right'? I've watched most of your episodes, but I don't recall one like this. Have you done one?

So we sort stars that still exist into two populations. Population 2 starts are the older ones. They contain between 10% and 1% as much non-Hydrogen, Non-Helium matter as Sol. Which suggests that their planets contain a similar fraction of those elements. But then in turn, this matter isn't equally distributed between the elements: it is very unlikely that any planet circling a Pop2 star would have enough of any element heavier than Fe to form an industrially meaningful deposit. These planets won't have Uranium, Gold, or Copper in enough abundance to support a planetary supply network. The younger Pop1 stars makeup about 2% of all stars in the Milky Way and they are younger in the sense that they are about 10 billion years old instead of 12 billion. To put it another way. There are about 2000 Sol- like stars that have rocky planets within an earth like habitable zone that are within 100 light years of Sol, working out to one possibly Earth like planet every 13 lightyears on average.

@@nicholascarter9158 Bit of an addendum to those numbers. Yes the Milky Way is about 2% Pop 2 stars, but just under half of all stars are Red Dwarfs (M-type)which are dubious at best as whether they could develop life. Great for an already technological civ to come in an colonize, but horrid for life to develop around. Red Dwarfs are highly likely to have volatile solar winds, and basically just strip atmospheres off planets (which would orbit closer than Mercury since it's a much smaller, cooler star) and there's a high likely-hood of tidal locking planets too, which is a nasty complication. Sure, there will be rare Red Dwarfs that are atypically calm and their planets might retain atmospheres, but these would be so rare that they'd be swallowed by your margin of error. Other end of nasty stars are your A, B and O-types. Way too short lived to meaningfully produce life, barely enough for planets to form in the longest cases let alone develop intelligent life. One step up from an M-type is the K-type, which are probably good candidates due to their stability and long lives but their fairly rare (12% of stars). Our star, Sol, is a G-type and even rarer (7.5%) and Sol in particular is a very calm G-type. F-types make up that last group, live long enough that they could develop intelligent life (in theory) and aren't unrealistically brutal like the A, B and Os but are very rare (3%). So really we're looking for intelligent life developing around Ks, Gs and Fs and they'd have to meet high criteria when it comes to solar wind stability, flare rates, flare intensity, and have a docile neighborhood (no supernova neighbors). Oh, and there has to be coincidentally a rocky planet in the goldilocks zone with liquid water. A binary star system (which most stars are bound in) greatly complicates the ability to form a goldilocks zone. So, yes, roughly 2% of all stars are Pop 2 and should have material for rocky planets, but that's just one box of an entire laundry list of boxes that MUST bet checked to develop life on a planet, let alone get that life to intelligence. Even then, if life gets to intelligence it might be stuck on a super-earth (which seem to be super common despite the Solar system not having one) where gravity is too damn high to reasonably escape with anything short of a fusion candle drive, and if we were stuck on such a rock we'd probably given up with ever trying to get into space. Imagine if it took all the effort of the entire Apollo program to put a single cube sat in orbit, just how quickly we as a civilization we give up on the notion of escaping the bounds of one planet. We DID give up interest after the Apollo program to a great degree. Such a species might be more prone to use the nuclear option that we thankfully backed away from. Or they might end up going the digital route and turning 'inwards to go outwards' as it were with virtual worlds. Either way, they're not building megastructures. There is a LOT of hurdles that need to be cleared, so many of these 'Great Filters' that when you apply them all with even a guesstimate of what the pass/fail threshold is, you get roughly one in a super cluster of galaxies. *looks around* Hmm, we might be that one. See the "Firstborn" and the "Great Filters" Fermi Paradox videos.

My solution to the Fermi Paradox: All civilizations advance to the point where they discover qlerb, and then someone with access to a college chemistry and physics lab can destroy the solar system they're in. Qlerb is a lot easier than interstellar travel or megastructures; I'm surprised we haven't discovered it yet, since we already have the baking soda and mimes.

The thing about FTL and/or Time Travel is that it SOLVES the Fermi Paradox. If we invent FTL spaceships and go out and find no one else out there, then that proves we are the first. If we get time travel, and find no one, then we are the ONLY ones. Thus, Arthur C. Clarke's quip becomes truly profound. "Either we are alone in the Universe, or we are not, and either case is really scary."

One thing I always like to point out in Fermi discussions is the in-built assumption that intelligent life might use chemical or electric power, rocketry, and extrasolar travel. A lot of our steps along that ladder were rather precarious and for most of our history unthinkable. Given that it took eons for us to do those things and we need to use the remnants of eons of dead things on our own planet to get them running (and we're close to using them up after only a few centuries), I think we often take for granted that techs to get to space, find much use in it, and be able to do things with it are immensely huge filters in and of themselves.

There serms to be alot of overlap between Fermi paradox discussions and filter discussions. The Fermi paradox, at its core, simply asks that given the size and age of the universe, why do we see no signs of advanced alien civilizations? In my opinion, that question has been answered definitively. We find no observable alien civilizations because there are none within our range of observation, period. That solution in no way implies there is no life (or even intelligent life) out there, just that there's none that have created a detectable civilization. There could be a stone age hunter-gatherer equivalent intelligent species every 100 light years, for as far as we can see in every direction, but they wouldn't be detectable with current technology. The question of why they never created a civilization that can he detected is, to me, a separate question from the Fermi paradox.

As to the question of Malthusianism and growth. The issue really is that we've often confused growth for development. Getting a faster CPU doesn't mean you suddenly needed more resources to make the CPU. In fact, many developments in the past and current times have caused a massive reduction in material requirements which has been probably the most important aspect of our economy. Now as to the question of growth, that's largely going to track probably a linear to sub-linear (probably logarithmic) scale rather than exponential or higher rate. As we see even today population growth curves have been flattening worldwide and not due to pandemics, wars, or comets smacking us a good one. We just start to settle as a people and focus more on ourselves than no raising kids. Now this might come back to haunt us but for now it seems we're still growing enough globally to exceed replacement numbers but without the so-called population bomb that everyone was so scared about. Ultimately, if we're to discuss resource wastage, that's something to do with the problem of capitalism and the false sense of the nearly unlimited scales of economy (mostly due to state interventions in transportation costs and the like), and it's not really an inherent problem with being a technological civilization. Hence why I distinguish between growth and development.

One main thing about discussing the fermi paradox, which borders me, is the time scale. When we look outside into the Universe, than we are looking into the past. So, from our state of view, the chances for other species must drop naturally, when we look further (farer??) away. We looking in a past, where the variation of elements are lower. First, heavier elements need to produced in dying stars or in other processes. Than there have to form new solar systems with this heavier elements. I don't know, what's a valuable time its need to form. Our system is round about 4.5 billion years old. An Alien- civilization that's, one million year old, isn't observable, when it's 10 million light-years away. We need 9 millions more years to observ them. Is it a bit clearer what I want to say?

He kind of mentioned this, though he didn't explicitly mention the elements thing, just the idea that life may be more likely to arise later in the universe. I know he knows that one of the most popular explanations for that is the lower metallicity of the past universe, though. However, he also noted that spherical shells of the universe further away have larger volumes. (He actually said that spheres have volumes proportional to the cube of the radius, but you can also say that spherical shells have volumes approximately proportional to the square of the distance.) That doesn't necessarily, or even likely, cancel out the effect of earlier stages of the universe being less likely to have life, but it does provide at least a partial cancellation, and, obviously*, goes beyond cancelling once you get close enough to us. *It's obvious because, obviously, a sphere of stars 500 light-years from Earth is more likely to contain aliens than just the rest of our Solar System, and our whole local group is even more likely.

I think the most reasonable answer, lacking any other evidence, is life being very rare and taking a long time to pop up, combined with the incredible distances involved. It may be that there are only a very small amount of other life-supporting planets in our galaxy, and because its so rare that means they are all very far apart. If the numbers are lower, it makes it more likely as well that the other like 3 life-supporting planets maybe just dont have advanced technology yet. Or maybe they do and we just havent recieved any messages from them yet, because they are hundreds of lightyears away. Its easy to forget that we have only been searching for aliens for what amounts to less than a century, which is nothing at all on galactic timescales. Its also quite likely there is life in other galaxies as well, but with FTL likely being impossible trying to travel or communicate between them would take thousands of years. We wouldn't know yet for hundreds of years if an alien civilization from another galaxy attempted to communicate or travel here.

That's definitely one of the Fermi paradox solutions, that every technological species in the observable universe has discovered how to migrate to parallel universes easier than expanding within our own. Possibly even before our level of technology for us to pick up no stray radio signals or anything. Maybe we will have this universe to ourselves, simply because we're the stupid species that missed the obvious and never figured it out.

I don’t think absent megastructures is indicative of a lack of advanced alien life, I honestly just think megastructures are impractical and such enormous feats of engineering most civilizations don’t bother with them. Why would you build a Dyson Swarm or Sphere when you discovered pure fusion or some other power source that provides far more energy than you will ever conceivably need? As for living space the more advanced we get the lower and lower our birth rates seem to fall, and there are countless worlds out there for expansion not to mention space habitats that can be built.

Yet another fantastic and informative video as always Isaac.

I love stuff about the fermi paradox. We're all quick to discredit Malthusian thinking (including me), but I think it's a mistake to rule it out. Humanity has been lucky that technological innovation has enabled us to keep a constantly growing world population fed, but we've seen how fragile things can be-- major disruptions to the supply chain due to the pandemic, or war affecting countries that are major suppliers of grain/wheat, can result massive food shortages. With a much more deadly pandemic or another future world war, we may suddenly find ourselves with a global famine. This may happen to us or to any other civilizations that may spring up in the universe. Imagine somewhere else in the universe where there is a world civilization where they do not manage to make agricultural breakthroughs, or major disruptions to food production and distribution happen, and they fail to keep their growing world population fed, so they never progress to the scale where they are able to build detectable megastructures. I believe civilizations need to reach a certain scale in order to be in a position to build detectable megastructures.

Or maybe we just missed it and are late to the party. Or perhaps it’s just space molluscs

Honestly I think the rough definition you laid out for what you mean by “civilization” is so insightful, and ought to supplant the term’s common usage. I’d argue that such a continuity of intelligence and information exists within different language groups, such as the Anglophone. The concept emerges most clearly when a very large group of people have sustained and frequent contact with each other - perhaps necessarily aided by shared technology and economy. I expect that we will one day have a more or less unified human civilization: less in the political sense, moreso a continuity of intelligence and information.

The Bronze Age saw very intricately connected empires, economies and travel from what is now Afghanistan to Iberia and even Cornwall. That tin trade was big money back in the day. Later on in the late Roman Republic Early Empire period we see that widespread, interconnected 'civilization' once again. Chinaware would be traded in India and go up the Red Sea and get sold in the markets of Constantinople. Trade has always been a hugely important facet of linking cultures together, I doubt that will change in the future.

Of course Polity also can be used to identify the end of a Civilization or nation because it transitions into a different form of government. Such as Rome transitioning from a Republic to a Imperial system with An inheritable title of emperor. Or the reverse can be done such as happened in Russia when the Xars were deposed and the Monarchy system was replaced with a Republic Communist system. Under the term Polity these can both be described as the end of a civilization and the beginning of a new civilization. It can also be used to describe the end of a civilization through violent means as well as Non violent means. A fictional example of a non violent one would be the Star Wars transitioning from a Republic to an Empire when they voted chancellor Palpatine into the emperor. A violent example in the exact same setting would be the rebel alliance using gorilla and terrorist tactics to overthrow the Empire and replace it with the New Republic.

Or, that a species will eventually learn to live well within its means with a sustainable population and lifestyles suited to its environment and not the other way around? Putting aside that building megastructures requires power sources and meta materials humans aren’t really close to producing, the very logic of extra planetary megastructures may simply be flawed and owe more to science fiction and wishful thinking that logic, much less the laws of physics.

Hey Isaac. Have you done a video on the minimum size a life form would have to be to reach technological advancement?

I'm thinking the assumption that advanced aliens would build detectable megastructures is false. As human technology has advanced we've favored smaller and more efficient rather than larger. Cars for example are considerably smaller today than the 1950's. Our communications have moved towards directed point to point, away from high powered omnidirectional. With this trend continuing I have doubts alien communications will be something that spills out over thousands of lightyears for us to pick up. Doing so is incredibly wasteful energy wise. I expect advanced aliens to favor efficient structures only as large as necessary for their purpose. This probably means we cannot detect them from a large distance.

@andrasbiro3007

Жыл бұрын

But then they'd just build a shitload of them, with combined mass and size comparable to traditional megastructures. The point is that if a civilization grows consistently, and has access to space, eventually their presence will be detectable, regardless of what they do, simply due to the scale of their activities. And the desire to grow comes from evolution, so it should be very common. Plus a single civilization is enough to colonize a galaxy in just a few million years. Even if they have absolutely no use of stars, or interstellar gases, they would likely still tamper with them. Just like how we rarely leave our environment in it's natural state, even if it has no practical use. For example you very likely don't want supernovas in your neighborhood, or dense dust clouds on your highways.

Isaac is also assuming very efficient devices. In this context, astronomers would expect to see an unusually large infrared (heat) signature, because even a very efficient device has waste heat (under known physics). The reason we think we could possibly see these structures is because we assume that other life would try to expand their collection of resources and space. This assumption is based on our understanding of natural selection, which seems like it would apply on other worlds as well. Given an expanding population, we think a sufficiently advanced species would try to gather more resources and even create more space (habitats). If that continues long enough, you end up absorbing and using a large percentage of the light from your sun. At that point, your system would have a really large heat signature compared to the apparent brightness of the star. So, yes, these expectations are built on assumptions, but those assumptions seem likely to hold true for at least some other species, because they seem to hold true for us.

You touched on it a few times, and it's the theory that most likely explains the fermi paradox aside from there just isn't any life visible to us with our current level of tech. It's that we're in some kind of preserve or zoo. Along that line, it'd be relatively easy to project some version of a universe at something as small as our planet, or solar system. If aliens wanted to hide us or themselves from what's going on around our region of space. I'm not 100% convinced this is the case, but it serves as an interesting idea until we can get out there far enough to disprove theories like this. In all likelyhood, we are just the first form of life to arise in this region of observable space. The universe is vast, and likely holds many forms of intelligent and advanced life. The odds that any of us would be clumped together, or be near enough to observe each other might be low though.

In this episode: Isaac Arthur takes off the gloves and starts bare knuckle boxing bad Fermi paradox solutions. Every blow hitting like a sledge hammer.

"Mortgage it's soul." Such a perfect way to phrase that.

I think the infinite miscibility problem is the one we have grappled with the least. I think that if you defined Earth like planets as "a living creature from earth can survive on this planet with no additional infrastructure" that you might find the diversity of planetary conditions so great that, even given the trillions of stars in the universe, a truly "earth like" planet might occur only once every 1,000 light years. I think what happens to most species is that they don't have the power to leave their star system. But what I think happens to the rest is that miscible planets are so rare, and environmental engineering so materials intensive, that the two or three planets they're able to colonize each succumb to their own independent extinction event, leaving behind a wandering population that can't sustain the species. I think the universe is a graveyard, and that what we would find if we could explore other stars is unintelligible structures on planets that could never support human life. The headstones of civilizations that died anyways.

Let’s take extra good care of the planet we actually have

The Fermi paradox has assumptions based upon human perspectives. Aliens may have other perspectives: Kang: "Stop! We have reached the limits of what rectal probing can teach us."

I love this topic, I remember when I first watched the dyson dilemma years ago

Every potential megastructure is explained away as something else because it's taken for granted that it being a megastructure is inherently the least plausible explanation for the phenomenon. That's quite the potential oversight. But, then again, we're a young species.

Not available separately, but only as part of a larger assembly. I don't know how this can be scaled up to the required size, and perhaps there may be a practical size limitation requiring a leap in technology farther into the future than we can predict. And perhaps alien civilizations have reached that limit themselves, and maybe won't be able to achieve it before their civilization becomes extinct, obsolete or that the practical engineering required is impractical for the purpose, or that a better technology is a favorable alternative.

Any thought given to the concept that extreme collectivism could be the answer to the fermae paradox? What I mean by this is utilizing the data network of the species to create an ever increasing level of interconnectivity until the (I) dissolves into the (sea of we) creating a hive mind that eventually evolves back into the (me). The me eventually discovering it is truly alone and suffering all of the psychological effects that the individual would suffer under such a situation until it either chooses to waste away or end its existence. We are fast approaching a technological capability that would allow the existence of such an (individual) composed of an entire species now. It is theorized that we will reach such a technological capability either just before we reach cardichev one or shortly after we reach that stage of civilization. I based this theory on humans being composed of individual cells combined together to create a collective consciousness known of as a human being. Though these individuals are composed of Possible trillions of cells they are capable of self destructing if forced into a state of prolonged isolation which can cause depression. Imagine a collective consciousness produced from the combined consciousness of an entire species. It would most likely have the starting point of that species social nature as a fundamental part of it's psychology. This means that it would be an individual that would find itself composed of trillions of cells suddenly looking around and realizing it is alone. All possible searches for anyone or anything to communicate with and interact with on the same level would be light years away. If it could find a possibility for such at all. So it is possible that such an entity would begin shutting down and withdrawing into itself until it waste away. Or it could possibly self terminate. Just like individual humans would under similar circumstances. It is perhaps depressing or horrifying to think about but if true it means that most civilizations would never really make it past the beginning stages of a type one civilization. If our own technological development is any measure to judge.

Only a matter of time.

I could definitely see a culture viewing the natural progression of the world as sacred... the argument about slowing entropy should appeal to some variant of some portion of some alien species... which means that we should see something in some surrounding galaxy... if we don't, that should be a very worrying increase in the fermi-paradox (there are easy explanations for our own galaxy, e.g. abiogenesis being almost impossibly unlikely etc. But it gets harder if there are 10,000 galaxies which show the same lack of von Neumann anti-entropy probes)

“No civilization can possibly survive to an interstellar spacefaring phase unless it limits its numbers. Any society with a marked population explosion will be forced to devote all its energies and technological skills to feeding and caring for the population on its home planet. This is a very powerful conclusion and is in no way based on the idiosyncrasies of a particular civilization.
