    Wouldn’t 50% of them die at the same time as the creatures that they live inside? Like unexisting 50% of humans would in fact unexist 50% of the bacteria in the humans who went poof.

    How does this argument make sense?

      If it’s all a truly random selection, which I believe it was, then half of all people would cease to exist, leaving half of their gut biomes behind, still alive (albeit briefly). I guess the end result would be the snapped people leaving behind a mist of gross intestinal bacteria which would itself mostly die out without a host. Meaning much more than half of all gut biome bacteria would be killed as a result.

      Of course it would make more sense to consider a person and their gut flora as one being, but the joke is about how stupid the initial conception of Thanos’ plan is, not creating an academically rigorous argument.

        This brings up an interesting point. The snap would have to run a multi pass check to make sure that by killing half of all organic life, it’s not causing the other half to die off. Otherwise, it wouldn’t be confirming to the will of the user, but then does it “scan” individual life types independently or as an ecosystem unto themselves, in which case is there precedence? Do food producing things get a pass, because otherwise the snap is just shortcut the process for half of the population. If it does leave the food producing ones alone, then really he’s just snapping away apex predators.

      Each bacteria is an individual living organism. So I’m guessing that (within this framework) the humans disappeared, but only ~50% (it would average out to 50% across the entire population) of their gut biome (or I guess any other living organism within them) disappeared.

      And as such, in people who did not disappear, ~50% (on avg) of their gut biome also disappeared.

      The math checks out…

    Thanos’ plan was unmitigated garbage anyway.

    Humanity reached 4B in 1975 and hit 8B in 2022. On that basis, if half of humanity died when Thanos snapped his fingers 50 years later we’d be back to 8B people again.

      That is NOT how species replicate. There are many factors where that number comes from. Including food and space to keep them. I read in college the max for humans is something like 10 million. But most scientists think it’s a already slowing down due to the struggles everyone deals with.

          That is not the only factor. But yes it would increase food capacity. But species are very aware of their drain on an eco system. We are starting to become more aware. But we know killing off one bug will effect harvests that effect everything including our food’s food.

        You mean 10 billion?

        Large cities can have more than 10 million people, so I assume you mean the other thing.

        Bluntly, half of the occupants of residences would be gone, and their stuff would be up for grabs. It would take a few years to stabilize afterwards, but it would mostly be business as usual for those who survived the snap (apart from the obvious mental trauma).

        Enough homes exist for the number of people who live here now, whether those homes are condos, apartments, detached homes, townhouses, or otherwise. A lot of people would be able to move somewhere more permanent, because the housing market would crash pretty hard.

        As we refill the homes the population would naturally return to the same level of growth we have seen previously… So after a few years, maybe a decade, max, humanity would be back on the population train straight to 8B again for sometime between 2050 and 2075.

        Humans don’t really follow the same population rules as apply to animals, bacteria, or other organisms in general.

          I meant 10 billion yes. And this study was specifically for humans. Saying we aren’t animals and we don’t live by nature’s rules just simply isn’t factual. We do things a lot differently but no matter what we still have instincts and those instincts drive us. We can’t just take out the hardwiring.

            We can’t take it out, but we can over rule it with reason and logic. We can decide to do something that’s not our “natural” choice.

            I know plenty of childfree couples, yet our biological drive is to create children to perpetuate our genes in the species.

            There’s a lot of exceptions to the natural human drives that most people experience.

              That is just one example. There are many natural drives that we still use. We eat. We breathe air. We drink water. There are plenty of natural drives that we cannot overcome. We are animals and all animals have things that affect their decisions.

                Except fasting, sometimes to the point of death. Food is available but we can choose not to eat it.

                Breathing can also be overcome by willpower and sapience, you can hold your breath as long as you like (until you pass out and you lose your sapience by way of being unconscious, and the autonomic systems engage which continue to respirate for you.

                People have a choice to drink the same way fasting works.

                Even fight or flight can be overcome. A notable example of overcoming some of the most basic instincts is the self immolation that some people have committed where they simply sit and burn rather than react in any other way (screaming, running, stop/drop/rolling, etc). There was a very public and newsworthy instance of this from a monk, who literally sat there, basically mediating while he burned to death.

                Pretty much anything that you feel a drive for, can be overcome, as long as you have the sapience and willpower to overcome it. Autonomic functions are basically immutable, so something like breathing is impossible to stop if you are not conscious to actively prevent it.

                Sapience and willpower can overcome any natural drive or desire as we see fit.

                I will recognize that getting people to agree to do something on a mass scale is generally impossible. Like herding cats… It’s doubly hard when that thing goes against their more basic desires.

                It’s been known to happen, but the instances are few IMO. Something like reproduction however, without a law or government mandate, it would be hard to prevent people from making more people and growing the population. Most notable example of this is countries where there are limits on how many children you can have. They’re successful, with some fairly horrendous stories of the consequence of non-compliance, and horror stories of what people have done to try to abide by the laws while still having what they desire (perhaps a child of a certain gender?).

                One of the natural drives is to have children. Multiple of them. Some, like me and my friends, have chosen not to do that. Sapience > natural drive. Limiting how many children a person may have is difficult, as we’ve witnessed from the countries that tried it, so making MORE children because we have the room/resources for it becomes a more natural outcome if the population was suddenly cut in half.

                Hell, if such a thing happened, and by some miracle my partner and I both survived the culling, I’d have a serious conversation with them about maybe changing our minds on the childfree thing. But that’s a discussion that won’t happen because Thanos isn’t real and can’t hurt us.

    That would imply that 50 percent of the snapped people’s biomes remained behind. All of the produce in the grocery stores would be covered in an airborne mist of E. coli, and snapped surgeons that were mid-operation would give their patients staph infections, assuming the suriviving surgery team was able to stablize and close them up before they died anyway. Neat.

    Also when those snapped people returned with the half of their biomes that also got snapped, you would get a sequel to the diarrhea. Diarrhea 2: Electric Boogapoo.

      Right? Taking even the people who disappeared into account, and their gut biomes, would you not consider them all as part of all life?

      If so, there may be some survivors with all of their guy biomes perfectly intact, and others who get unfortunately zilched.

      If the 50% are homogeneously spread -and it’s implied that it is-, then one may assume 50% per person also applies. Like how he didn’t leave 50% of planets alone and purge the rest.

        I would think it’s basically a coin flip for each living thing. It’s possible, for example, that all humans survive, however the probability is so astronomically small, it’s functionally impossible.

        Same with gut biome. Even with several billion attempts, the probability that even 60% of any individual’s trillion gut microbes get snapped would be essentially functionally impossible.

          Just to give an idea of the unlikelihood we’re talking about here, you can model this as a Bernoulli process with a binomial distribution.

          If N is the number of beings potentially snapped, then (√N)/2 is the standard deviation. (If you’re curious about why, you can read more here.) So for 8.2 billion people, the standard deviation is ~90,000. The chance of being more than ~3 standard deviations below the mean is 0.1%. That means there’s only a 0.1% chance of snapping less than 4,099,720,200 people.

    Thanos’ snap wouldn’t kill 50% of each survivors’ gut microbiome, it would kill 50% of all the lil buggies that compromise all gut microbiomes, and if the snap effects individuals randomly, you’d see a normal distribution (I think, I haven’t taken stats in a decade). So some survivors would retain 100% of their microbiome, some would lose it all, with a bell curve in between, probably with the peak around 50%.

        There was never any such ideas being part of it. It affected plantlife and bacteria as well. The idea of a soul to begin with is not even supported by science, although most people consider it to have some kind of validity, even if it’s not quite definable. But the relevant issue is that it’s all life period.

    Look, we’re in the realm where the guy decided to remove 50% of all life… as a resource conservation attempt.

      I don’t get why we keep acting like this is such a strange idea. Thanos saw the universe as over-populated. So he could have changed the framework of the universe to accommodate this bloat, or he could have preserved the universe’s structure as it is and tamped down the numbers to fix the bloat.

      The key here is understanding that he doesn’t see the universe as flawed, he sees the life as flawed; why would he fix the unbroken part of the equation to accommodate what he sees as the broken part?

      It’s like if your garden gets overrun by gophers - do you eradicate the gophers to get your garden back or do you decide “well I guess I’ll just double the size of my garden so we can both share it!”?

      Also the Infinity Gauntlet is neither a genie’s lamp nor a Monkey’s Paw. There’s no clever tricks, no perfect wording needed. It’s based on his intent. He may have said “half of all life” but any amount of nuance he wanted to enact in that moment of omnipotence, he had. I’m sure half of the plants didn’t die just because he didn’t say the word “sentient”

        Well, if you’re gonna be really nerdy about it, keeping the ability of life to reproduce intact and culling 50% of the population once only gets you one slice of the doubling time back. I’m not the first to point out that Thanos started a galactic war to send the population of Earth back to 1975. Tony’s kid would still be alive by the time humanity thwarts Thanos through sheer horniness.

        He’d have been way better off by making every sentient species like 90% less likely to conceive or whatever. Except then most animals and plants would go extinct, so what’s the point. It’s really very unclear what “resource” Thanos is trying to preserve.

        So… you know, if his take doesn’t make sense in the first place, and we do know that he at least impacted animals, because the movie explicitly shows a bird showing up as a confirmation that the un-snap worked, it’s not a crazy idea to ponder all the other ways it’d be weird, counterintuitive or self-defeating. Dead gut biomes, suddenly liberated E. coli, sudden deserts and unexpected outcomes of random distributions are all fun thought experiments, I suppose.

        But mostly, it shows that it raises enough questions to break suspension of disbelief a little, which I think is the biggest sin of that particular change. The comic take is absurd, but at least it settles the question.

            That’s fair, I suppose. I’d just argue that the movie forgot to… correct him? Endgame even makes a point about how nature is healing and the air is cleaning.

            If the point was that he was wrong and misguided, the movies didn’t make that clear. Instead it was just “he’s ruthless and evil, but he maybe has a point” as an angle, which is a really weird way to frame your omnicidal nutcase.

            I get why, relatable villains are more interesting, especially if you’re going to have the entire movie revolve around him. It’s just that they went about it in a way that raises questions.

      No, viruses don’t mean the scientific definition of life. IIRC, the primary reason why is because, in order to make copies of itself, it must hijack a living cell’s reproductive system to do so. It can’t simply divide to make more of itself.
