*That almost sounds like something a Many Worlds fan would say, according
to it another name for the Multiverse is the Universal Wave Function. And
there is only one of those. And according to Many Worlds things are
completely deterministic, the reason we are uncertain is because we lack
information. Why is that if everything is part of the same wave function?
Because in quantum mechanics a "state" is a vector in Hilbert space (a
vector space that has infinitely many dimensions), every property a
particle has corresponds with a vector in Hilbert space. And when you
observe something you are looking at how closely one vector aligns with
another vector. And some vectors, like position and momentum, and energy
and time, are perpendicular to each other. *

*And it's impossible to align a vector with two mutually perpendicular
directions at once, the more precisely you pin down one component, the less
you know about the other. And that is the source of the Heisenberg
Uncertainty Principle. And that is the reason things seemed
nondeterministic even though Schrodinger's equation is completely
deterministic. And that is the only reason it makes sense to talk about
separate "worlds".*
