Quantum Mechanics for Dummys.
Physicist: As much of a trope as “Other Quantum Worlds” has become in sci-fi, there are reasons to think that they may be a real thing; including “other yous”. Here’s the idea.
Superposition is a real thing (on small scales at least)
One of the most fundamental aspects of quantum mechanics is “superposition “. Something is in a superposition when it’s in multiple states/places simultaneously. You can show, without too much effort, that a wide variety of things can be in a superposition. The cardinal example is a photon going through two slits before impacting a screen: the double slit experiment.
