Wow, I was a bit behind. I d/led episodes 21-25 and have started listening to them. I just finished listening to episode 22 (and started 23) and thought I would pop in and try to make the time travel/mwi theory a little easier to understand.

In the Many Worlds Interpretation (mwi) states that any decision in the past has the potential of creating at least 1 additional dimension of existence. If one were to travel into the past, their simple existence there would generate another dimensional world to account for them. Some of the changes start (and sometimes stay) small, a simple decision. Perhaps Byron decides to walk to the other side of the road instead of the other. A minour change, but what if Byron is supposed to meet his future wife because he walked down the other side of the road. In this reality, where he crosses the street instead of staying on the same side, he never meets the woman he's wouuld have married, and he never has what-ever family he's would have had. His great-great grandson doesn't cure cancer, all because Byron crossed the street instead of walking down the side he's on.

I'll use one of the examples given in the podcast.

If I were to travel to the 1920's to kill Hitler, reality would create another dimensional existence to account for my existing. Nothing I do there would have any effect on my history. It would, however, have an effect on that alternate time-line that has come to exist because of my appearance there. In this other, new Earth, Hitler is killed and never comes to power. If I 'return' to the future at that point, I'll still be in the alternate universe, thus I would see the after-effects of my actions. If I were return to the past, to the moment I first appeared in the 1920's, and moved forward again, I would find that nothing I did had any effect because I had returned to my own world.

Hmmm... I hope that makes it a little easier to follow. If there are questions, anything I can do to help clear it up, just ask. Quantum Mechanics are kind of my thing...

i think that was a good theory, I had never heard that theory before, but when you think about it, it's the only way to get around most of the time travel paradoxes
