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.
50% of all ≠ 50% per person
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.
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?
pining after an annoyed Aubrey Plaza
Can’t have your bad guy be that relatable. Everyone would just be cheering against the avengers.
