If you change the future, do you change the past.
Like a magician stacking the deck. Or a poker player folding when he should have bet. Are the cards reshuffled?
Or maybe history changes the rules. Is there now, as there might always have been, five aces in the deck?
If you look at your life, as a race. And there are to keep it simple, 100 different dimensions.
And lets say that in every dimension there is a different eventual outcome. In some you are rich and some your dead.
All of the you's in these dimensions start the same and are running @ the same speed.
Do the choices we make shift the dimensions we are currently running in? Are we in a huge choose your own adventure story, with an infinite number of predetermined outcomes?
From what I can understand of Quantum Physics the answer is most probably, Yes.
Choose your adventure wisely my friends!
