If surviving humans lost 50% of their gut bacteria, that means that those snapped away left 50% of their gut bacteria behind.
More gut bacteria for the rest of us, that's what I say!
That's not how it worked. He killed 50% of gut bacteria by killing 50% of the hosts.
Source? I'm pretty sure random bacteria would still be around a while if your brain activity went to zero.
But that’s not what happened. They literally disappeared, along with the gut biome
Your biome is specialized to live inside of you. They are not identical to wild organisms.
Yeah my interpretation is that half your cells would die - didn't even consider that if half your brain cells died it would probably kill you instantly.
Fewer than 50% of the cells in "your body" contain your own DNA.
There are many more bacteria, since they are much much smaller than "your own" eukaryotic cells.
Where you end and your "gut flora" begin and end is not as clear as you might first believe.
The snap was always the dumbest part of the entire avenger series. Let's say for example, you have a bunch of deer that are eating the forest bare, so you let hunters kill half of them... Then what happens next? You have the exact same problem in a few years. The snap solves nothing.
Also if you can snap your fingers and do this, why can't you snap your fingers and make twice the food supply?
The snap is just stupid, even in a world made-up physics-defying superheroes.
To be fair, it made slightly more sense in the comics, though still batshit. In the comics there was no noble purpose like they tried to shoehorn in for the MCU. IIRC, Thanos was literally doing it to impressed Death (the cosmic entity) to gain her affection.
makes more sense for sure
It's stupid only because they try to rationalize it.
Comics Thanos just wants to commit genocide so his crush notices him. That's also stupid, but he's a big purple space alien so what can you expect? Using a magic space glove powered by stardust and wishfish to kill half of all life as an incredible gesture of his devotion to Death makes internal sense.
His crush is literally Death, so it kinda makes sense that genocide would be the way to get her attention.
Even worse than that. 50% of all life dies, right? That's 50% of the plants too. If you know anything about food chains, taking 50% of everything leaves the top of the chain massively overloaded.
In reality, since it was more random, some poor soul would have their whole biomes destroyed, and just be rekd.
That would be incredibly unlikely. Due to the huge number of gut microbes, the chance to even lose 5% off of the median, even with billions of trials, is functionally zero.
To expand a little:
For a much smaller sample size of just 1 million, the probability to lose just 1% off of the median is basically zero.
WolframAlpha doesn't even bother to calculate the exact result and just rounds it:
https://www.wolframalpha.com/input?i=P[490000+<+X+<+510000]+for+X~B(1000000%2C0.5)
Losing 50% of your gut bioma will be fixed in an hour or two.
Yeah, yeast doubling rate is around 90 mins in optimal conditions, I would assume the rest of the microbes in your gut would have a very similar rate and they would be well adapted to those conditions.
Yeah but I thought about this I realized that whenever somebody vanished from the snap it would leave behind a slurry of gut microbes and a (different looking) dust from all of the skin mites, microbes, and stuff that just live all over the human body. Meaning the aftermath would have been even messier.
Maybe that's exactly what the dust was.
Then it should have been goopier lol
he would have to snap his fingers infinitely many times to kill everyone so he is not that powerful
That’s an interesting question as to whether the infinity gauntlet rounds down.
Like, if there were 3 survivors of a species and thanos snapped the universe, does the gauntlet round up to 2 survivors, or down to one?
The snap must take intention into account, like a genie, and not the literal wording of the wish, like a monkey's paw, because otherwise everyone in the universe would have just been cut in half.
But also: what if Thanos himself got snapped out, along with the power glove (because for some reason it turned their clothes into dust, too)? The heroes would have been fucked, right? It's been a minute since I saw the movies but IIRC, they used the time stone to go back in time. But what if the stone was gone because it was part of Thanos' attire? He himself used the stones to destroy the stones, so there is probably a timeline where he got snapped away with everyone else, destroying the stones in the process.

It might not be possible, since the stones were also performing the action, and Thanos didn't want to destroy the stones while snapping everyone in half. Otherwise, they might just self-destruct by going for the nearest target first (Thanos), and stop there, not fulfilling the desired action. You'd have to destroy/scatter them separately.
I don't think that they used the time stone to go back in time, since it was destroyed when they got there. They had to get it from the past, since a decent part of the movie surrounded that.
I imagine the stones would survive it, just fall out of the vanishing gauntlet. It's not like the stones were a part of it, they were just being held in place by it, but then there's the question of whether or not the contents of people's pockets got snapped as well, we know the pager Fury had didn't count as "part of him".
And no, they used the ant man tech to go back in time, no stones there.
So will bacteriophages and viruses be snapped as well? Does it mean that scientists can utilize the Thanos snap to determine for good whether viruses are alive?
It's bullshit space magic, it probably considers what Thanos thinks of as life. Why it snapped the birds is a different plot hole altogether, because it means he snapped away half the food, too.
50% fewer people working all critical sewer infrastructure, too
50% less financial analysts too :( imagine the economic crisis that would cause.
If you want to be really technical the survivors would also lose 50% of all the other cells in their bodies and probably wouldn't live another few months. I'm not a doctor so I won't try to put a number of weeks, days or hours on it, let alone argue that number, but hey knock yourself out.
/edit based on another comment - even if you could stay physically intact with half the cells in your body dying, half of your brain cells dying would probably kill you instantly.
If you include bacteria, then probably no human died from the snap. There are significantly more of them
That's not how percentages work
Moreover, that's not how probability works in independent events.
It'd be like saying "I flipped coin A 1 billion times and got half a billion heads, so now that I'm flipping coin B 100 times, I probably won't get any more heads."
It should be fairly obvious that you can say the exact same statement about tails, and get a completely contradictory statement.
Say, there exists 2 humans and 98 bacteria. Consider all cells of a human one life.
50% of ALL life doesn't care which species the life is, and therefore there's a chance that 50 bacteria die. The probability of that happening is 98C50 / 100C50 = 98! 50! 50! / (100! 50! 48!) = (50)(49) / ((100)(99)) = 0.247
For my previous argument, I did not actually do the math. Now that I have done a little bit, the probability seems to converge at 25%
Obviously, this is based on the interpretation of "all life". For my interpretation, "all life" includes every life in a single set, and apply the 50% snap to that. For some others however, it may be interpreted as each species in their own set, and the 50% snap is applied on each set individually.
