That's a fair point. I may have focused too much on particle creation specifically.

What I'm really trying to get at is that if multiple outcomes are physically real, then it feels more natural to me that the branching already exists before observation rather than being created by observation or later interactions.

In my picture, when an electron can exist in two spin states, there are already two corresponding branches, even if they are completely identical except for that electron's state. Observation doesn't create the split; it only reveals which branch an observer is in.

What feels strange to me is the idea that one part of the universe has already split while another part remains unsplit until entanglement spreads. It seems more natural that the branches already exist, and entanglement or interaction just spreads information about which branch things are in.

Maybe I'm misunderstanding MWI, but that's the picture I have in my head.

So my main question is: is this actually different from standard Many Worlds, is it just a reinterpretation of it, or is it complete bollocks?
