*Schrodinger's Equation describes a quantum wave function and it says
absolutely nothing about that wave terminating, therefore if anything
a _finite_ number of branches have been ruled out. However, if I'm
being fair I have to admit that Schrodinger's Equation can't be the
entire story because it makes no mention whatsoever of gravity, and it
is probably the most fundamental of all of the 4 known forces because
it is the only one that affects spacetime itself. The equation doesn't
say gravity can't exist, and it doesn't say gravity must exist either,
instead it simply ignores gravity entirely. That's why Many Worlds
proponents don't claim to know if there are infinitely many branches
or just an astronomical number to an astronomical power of them. *

*So if Schrodinger is incomplete why do I think those other worlds are
real? Because we know from experiments that things get weird when
things become very small and Many Worlds can explain that weirdness.
And when things get that small gravitational effects become
negligible, or at least they do until they come close to the Planck
level, and that is well outside our experimental range so nobody knows
what's going on there. *
*As for Bruno's ideas I had two basic problems with them. He believed
mathematics was more fundamental than physics while I thought the
opposite, and I thought his ideas concerning consciousness were
worthless.

He just believed in *more* mathematics being fundamental than you do.
