- TL;DR Summary
- How many branches are possible after measurement?

Say you have a simplified 1d Gaussian wave function describing location of a particle.

Many worlds says that every outcome is a separate branch. Copenhagen says you will get one of those branches.

So how many distinct positions, imaginary or real, can you generate from a fixed segment of a Gaussian curve? Are there N plank lengths under that curve? Can those plank lengths be divided in half, or 10 or more?

Interesting thought, I can see no difference between Copenhagen and many worlds from the perspective of an observer. They are functionally the same. I guess this is sensible otherwise measurement would be wrong for one or the other.
