Well actually Moloch my view is sort of like yours but mine differs a little. Every choice we make creates a new universe(s). Those universes are based on the results of the other choices we did not make. This goes for every person and they are infinitely growing in number all the time.
CM - To oversimplify a simple topic
Okay I see Moloch's angle and I will try to apply example. The universe is big, it is expanding, It is infinite. There are stars, glaxies, black holes, comets, and planets. (small list to be simple) Each universe is like this, they are just copies of ours with subtle changes. Each subtle change creates a new universe. This subtle change can effect the universe in a big way or a small way. In one universe we may of blown up the moon, in another it is fine. In one universe we blew up the moon and mars. In another the moon is blown up but mars is fine. In this one both are fine. But very subtle changes can branch off into new universes.In one universe you may be rich, in another poor. You could be a queen or just a wench. In one universe you could be the president of the united states. With this in mind you could be anything.Even the order and language I typed these words in would change and create new universes. That is how infinite they are. How subtle the changes can be. Essentially it boils down to time is an illusion and you are everything.

You want a real mindfark? All of what you percieve, and all of what you don't perceive may be nothing but three dimensional holograms rendered in four dimensions and embedded in a universe of infinite dimensions. Try wrapping your brains around that one.
