What if all of this already happened? :)
I think that's the whole point about time traveling.
I understand the motivation of phisics to find a solution and is fascinating.
Supose that time traveling is posible at year 15000 (or maybe at 100000). Earth totally polluted, water valuable as gold... etc. I think one of the first thing to change in the past could be internal combustion machines, maybe introducting "magically" some kind of machines based on renovable energy. With a change of that nature, every thing in the world could change... change at the level that most of the thing that we know simply.... dissapear ?? (and the energy resultant of this transformation at molecule level in all the world) .
So, in the case of time traveling was possible, and one can change something in the past, how this person could be ensure the change affects ONLY some facts in the past, but others related in the future, be inaltered ?
When i read something about this theme, i am more confused.
