Re: About the Multiverse
I have attached a diagram to help explain the following. It helps if you zoom on in.
I don't think that you jump into other universes when things happen. I do think that different things happen in different universes and I also beleive that to travel through time you MUST go into another universe.
Why must you go into another universe? See the green line in the diagram below. If you attemot to follow that line, you run into yourself. There is an insurmountable difficulty. The moment you try and travel back, you exist at every point you travel back to. But that means you are attempting to travel back to a place and time you already are - and since matter cannot occupy the same space and time, you cannot do it.
So you must try and travel into another universe. (Blue line). That path is possible, you go to another universe, spend some time there and come back to your own universe at the same time you left. Nothing has changed in that universe, accept you, who are a bit older.
The purple path is the interesting one. You can go to another universe, then time(universe?) travel back to yours. Once you are there, you spend time and cause all manner of trouble. You jump to another universe and then back to your time and universe. And things have changed inviting all manner of paradoxes.
And what's the point? Well, one, to elucidate the above. Two, to try and create a framework for analysis this whole multiverse stuff. I hope it helps!
