“I favour an interpretation of quantum mechanics (the 'Everett interpretation') according to which reality branches in any chancy quantum situation. On this view, Schrödinger's set-up will give rise to in two future branches of reality, one with a live cat, and one with a dead cat - and the talk of '50% chances' just indicates that the two branches are both equally real futures of the cat that originally entered the box.”

About This Quote

Source Paper: "Everett Interpretation" discussion, 2000s

Reality splits into multiple equally real outcomes whenever quantum events occur, making probabilistic language a description of branch weighting.

In simple terms: Quantum events create multiple real futures.
