    Killing 50% of your gut bacteria is a big nothing.

    These things reproduce on the timescale of hours.

    I kill 90% of my sourdough starter every time I feed it, and it bounces back the same day.

      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.

        I’m not sure it’s stated, but I thought the planets that had already been purged by Thanos’ armies, like Gamora’s planet and Xandar were spared the snap.

    Or the 50% of all people that got snapped took 50% of the gut bacteria with them, leaving the rest with no loss to their gut biomes. (taps forehead)

    E. Coli reproduces so fast that a population can double in size in half an hour, and human feces is 50% bacteria by weight.

    If your gut microbiome got snapped it’d be back so fast you wouldn’t even notice. Bacteria are kinda scary.

    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.

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

    Lovely movies, but the “guy’s a literal death cultist” required way less suspension of disbelief. Jilted incel Thanos pining after an annoyed Aubrey Plaza or whoever would have been way more timely, too.

    But if we’re doing it this way… 50% of the plants, algae and plankton would have died too. XKCD MUST have figured out what that’d do to the atmosphere by now, right?

      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.

          I dunno man, “a madman thinks he understand the universe way more than he really does” doesn’t break suspension of disbelief for me. I agree with you that his plans are flawed, but he’s not infallible. I’m not trying to gage whether or not his plan makes sense, I’m trying to gage whether or not him believing it makes sense. History is full of arrogant men with half-baked plans for salvation; I don’t see how Thanos is any different.

            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.

          To be clear though, I also agree that the comic book version of Thanos’s motivation was way better. Like not even a competition. But I don’t think the MCU version is so nonsensical so as to be unbelievable as a motivation.

    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.

      Edit surely you had to have meant that. The US alone has almost half a billion people. Most countries have well over that number so I’m attributing it to mistype

        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.

    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%.

      That bell curve would be extremely narrow. You have so many lil buggies that basically every human survivor would lose ~50% buggies.

    Even if that were how it worked, which I don’t accept, it wouldn’t be months, it would be a week or two at most of difficult bathroom time.

      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.
