Not all things are possible, only potentially possible ones. If you take all the numbers between zero and one, you will find an endless supply of distinct numbers but none of them are 3.

Superdeterminism... quantum noise and the which way paths are all correlated.

Just a reminder.. Hilbert space is just a tool/abstraction/map... and the map is not the territory..

It’s not ‘all’ things that are possible, just things that are allowed within the laws of physics :) Subtle difference, but energy conservation for example has to be adhered to.
