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!)

Answer 1

No, it doesn’t do anything of the sort. All it does is demonstrate wave-particle duality. In other words, all it does is demonstrate that quantum objects sometimes act like particles and sometimes act like waves. There’s nothing in there or anywhere in quantum mechanics that leads to any conclusion that there are alternate realities.

In fact, there is no serious interpretation of quantum mechanics at all that has anything to do with alternate realities. Many people misinterpret the Everett many worlds interpretation to be about alternate realities, but it does not mean that in any way.
