>>12942256>flip-a-coin-make-a-new-universe crap>>12942268>that's what the math tells us should happenYou're both wrong. "Flipping a coin" doesn't "create" anything. The separate universe was always there and always would have been there.
The deterministic Newtonian paradigm predicts a single possible world predetermined by the physical states of the past. Quantum uncertainty dashes this by necessitating multiple possible outcomes futures.
MW reigns this back in by saying that all possible worlds just exist simultaneously. Whereas the Copenhagen interpretation is non-deterministic, MW is actually deterministic.
A deterministic classical universe is sort of like a film, where everything is predetermined. MW is like a videogame with multiple endings, or multiple possible game states. They all exist simultaneously in the game's code. Actions in the game that determine a certain ending do not "create" it, it was already pre-programmed.
