Parallel Worlds Probably Exist. Here’s Why

The most elegant interpretation of quantum mechanics is the universe is constantly splitting A portion of this video was sponsored by Norton.

We can use the Schrödinger equation to solve for and evolve wave functions. Then we invoke wave-particle duality, in essence things we detect as particles can behave as waves when they aren’t interacting with anything. But when there is a measurement, the wave function collapses leaving us with a definite particle detection. If we repeat the experiment many times, we find the statist
