As a big scifi fan I thoroughly enjoyed your theory. You reminded me of Steve Caroll and theory of multiverse. If you can listen to him at Joe Rogan's, I highly recommend it. Just having a renowned physicist ponder over how every decision creates two realities sent small chills down my spine.

I'm familiar, but I also don't believe in a multiverse. I believe this is the only reality, as the wave function always collapses in the now, and, consequently, why I don't belive that time travel, in the sense of us jumping through time, a la H. G. Wells, is possible.
It sure is fun thinking about it, though.
