the multiverse theory is along those lines.... where every choice you have is played out in a different timeline or "reality" all at once.... so every choice you actually make is here in this reality, but every choice/option you could have made is also played out simultaneously in alternate timelines....creating a multiverse of yourself...….. like now i have chosen to eat a doughnut instead of my fruit bowl (don't judge...lol) but in an alternate timeline im eating the fruit bowl.....hmmmm actually now i don't feel so bad.....lol...well anyways, that's the basics, before Debi causes my head to explode and i will not even be able to fathom that much again......lolI guess the real question is could other galaxies hold an opposite versions of our selves with different timelines.
