Does the experiment where a single photon goes through 2 slits really show the universe is constantly dividing into alternate realities?

Question

Probably not well worded (bad at Physics!)

In: Physics

Answer 1

No, it explicitly *doesn’t* show that, and cannot possibly show that. Any alternate reality would by definition not be something we experience.

The double-slit experiment shows that a photon is not “just” a little tiny ball moving around.
