I get that doing something like this is basically impossible using any practical technology, but I just wanted to know if there was anything about it that was impossible in principle (e.g. not even an ASI could do it).
The main problem that I wanted to ask and get clarification on is whether or not we could know the measure of existence of branches that we cannot observe. The example I like to use is that it is possible to know where an electron “is” once we measure it, and then the wave function of the electron evolves according to the Schrodinger equation. The measure of existence of a future timeline where electron is measured at a coordinate X is equal to the amplitude of the wave function at X after being evolved forward using the Schrodinger equation. But I am guessing that it is impossible to go backwards, in the sense of deducing the state of the wave function before the initial measurement is made using the measurement result (what was the amplitude of the wave function at Y before we measured the electron at Y)? Does that make sense?
