Quantum Cat: Is the Wave Collapsed if Box Isn't Opened?

[Derek Potter]

I do not believe God plays chess with the universe.

 

[Nugatory]

Why not suppose that the chessboard (the "calculating device") is the universal wavefunction and the moves are collapses?

Feynman clearly states that he is making an analogy. Furthermore, this analogy isn't to how the universe works but rather to the way we make inferences about how it works. You can rework that analogy to use a computer game but it doesn't stretch into being a testable claim about how the universe works.

We have drifted far enough from the original question and from science into philosophy, that it is time to close this thread.
