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

So you’re talking about the “Many-worlds interpretation” of the double slit experiment.

This is the idea that individual particles act like waves because they are able to collide with themselves in a parallel universe, so you get a wavelike pattern instead of just a single particle that goes in a straight line.

This theory isn’t really accepted though as it doesn’t have any way to explain gravity. Linking gravity to quantum physics is currently a big area of research in physics.
