What exactly is a hash collision? What is a real life comparison of one?

two people, having completely different parents and ancestries, being virtually identical (presumably their DNA). a collision of probabilities

Genetic reincarnation! Same Y chromosome, same mitochondrial DNA, similar autosomal DNA == natural clone.

basically, the existence of a collision would make the hash function not a true function (fails the vertical line test). say you have a function, f.

f(1) = 10
f(2) = 20
f(3) = 30

now, if for some reason, f(88) = 10, you would have a collision

your question makes me think of birthday paradox - an increasingly high probability of collision with crowdsize

somehow two different inputs give an identical output, which one makes the assumption is (sometimes extremely) unlikely. I think @1617 did a solid job explaining.

is every particle a hash collision?

We need ANSWERS!

How does this apply to the multiverse?

Interesting stuff

this would mean that the theoretical derivation function is lacking isomorphism, so you couldn't work back (or would get multiple possible states) to see what "collided"

Hmmm, I'd say it's like particle physics.

Systemic errors create unexpected readings. But the chance of getting a false reading after a ton of data is insignificant.
