Not sure if you meant it that way but information actually can't be created or destroyed in quantum mechanics. This is known as the no-hiding theorem [1] which has been experimentally proven and which leads to the black hole information paradox. [2]

- bouncycastle 6y agoSo, is it kind of like a cryptographic hash function?
- infogulch 6y agoSomewhat. Like a hash function, it projects some large state space (the hash input/you) onto a different state space (hash digest/2d-surface of a BH). But a hash digest actually has lost information, i.e. it's guaranteed by pigeonhole principle that some two inputs have the same digest, which means you lose the information about which one it was. Whereas a black hole scrambles you, but none of the "bits" are actually erased, just smeared out and projected onto the surface.
