    Bacteria multiply crazy fast… as long as the food source was uninterrupted I’d almost guarantee you most people’s microbiome would be fully recovered in just a few hours and they’d not even notice.

      Yeah 50% loss isn’t servere at all for gut biome loss. If you’ve ever been on antibiotics you’ve likely experienced that or worse.

      Our doubling time isn’t that bad either. We reached 4 billion in 1970s. If we round up the current population to 8 billion that’s about 50 years. That’s all that thanos would add by the snap. Even less probably because we have better medicine now so it would be easier to reach that number.

        I kind of expect developed countries would maintain the current trend of being slightly below replacement value. Probably depends on the psychological impact of the snap. People tend to have fewer children when they know the ones they have are safe.

        But your point is a good one either way.

      How long can gut microbiomes survive after the host is dead? Wouldn’t a dead host essentially mean near 100% fatality for the gut microbiome meaning that anybody killed by a Thanos snap would also mean a 100% kill rate of their gut bacteria, leaving any survivors to basically keep all 100% of their gut bacteria?

        Well the implication in-universe is that the actual snap was killing 50% of all life, not any death afterwards. If we’re counting bacterial life as individual living beings in this 50%, then it shouldn’t matter whether the host itself got snapped or not, since the bacteria are “separate” and would be left behind after a snap…

          Does this mean that for every human that disappeared there should have been massive piles of bacteria and shit left where they were last standing

            Even better, your microbiome covers your entire body (anything exposed to air) and into any organs that are part of the waste processing system.

            So briefly after the snap you would see a vague outline of the creature, with a well defined digestive tract (mouth to anus), eyes, nose, ears, sinus system, and bladder. Because bacteria, viruses, and fungi are all quite small, the cluster of gut organisms would probably fall, and the rest would drift away. Imagine being in a crowded space and just breathing in all those bacteria, viruses, and fungi… 🤮 I bet a lot of people would die from infections.

            If the creature had any parasitic infections, like a tapeworm, that could also be left behind.

          Right so then couldn’t it follow that human survivors may have no impact on their gut bacteria? If there are only two people and their microbiomes, and the snap kills 1 person and their entire microbiome, then the surviving person would have no or microscopically small impact on their bacteria assuming an even distribution of bacteria across the two people. Basically the OOP is assuming that of the people that died, half of their bacteria would survive, impacting survivors’ microbiomes, rather than assuming 100% of bacteria would die with their hosts, leaving the surviving population’s bacteria intact.

      It wasn’t an even 50% from everyone though. Some people had no loss of gut bacteria, other people had 75 - 100% snapped away

        That’s not how statistics works. Every person will lose almost exactly 50%.

        Estimates for the number of bacterial cells within the average 70kg Human male is around 38 trillion

        https://en.wikipedia.org/wiki/Human_microbiome

        Do you know what the chance of 100% of them being snapped is?

        0.50 ^ (38 trillion) = 0.0000000000000…

        The calculator ran out of zeros.

          It depends on how the snap worked. It was 50% of all life in the universe. Was that 50% of every species? Or just 50% of all living things? If it’s the latter it’s possible some species were missed entirely while others were completely wiped out.

            If it’s alive it had a 50/50 shot.

            But no one lost 50% of their own cells, so clearly if it’s alive and can be classified as a single organism. Is the gut micro biome an independent body of organisms, or is it just like any other organ of the human body, and thus would have been unaffected by the snap?

            Either everyone lost almost exactly 50% of their gut biome, or, about half of all living organisms lost 100% of it, or, no one lost any part of it. Those are the only three possibilities.

            The more interesting question is were viruses affected? Or did the magic stones not consider them life?

          It’s random and it effected the entire universe. Can your calculator tell you how big the universe is?
