Paradox
So the situation is this. Someone goes back in time for some reason. When the person goes back in time, they fix the problem, so now in the future, they no longer have a reason to go back into time, thus creating a paradox. I think, that since the person went back in time, their existence is set, so although the person changes the future into a future where he has no longer a reason to go back, he shall stay in the past. If one goes back, they are now existing in the past and a part of the history of the past. What happens in the future is a different matter entirely. Simply, the person who went back in time no longer has an existence in the future. He did exist in the future, and there should be records of that, however, he longer exists in that time, and so he simply "disappears" from the future world.

Assuming time existed. If someone goes back and fixes the problem the person no longer has a reason to go back, meaning he did not go back, meaning no one fixed the problem, meaning the problem is there and someone has to go back, etc. Also, going back would mean multiplication of energy and matter from the same universe, assuming the person would not just go puff and would simply exist the impossible existence. Someone goes back and changes things so that the future same person would always go back to the one specific time and tell him/herself to go back to the one specific time - instantly the universe would be filled with that person. A new universe created with every time-travel, instead of clogging up even the black holes? Created from what? Time-travel is supposed to be inside the one universe, so there would literally be nothing that could create another version of the same universe outside the universe. You can't use one, limited, thing to make more of the same. Sorry, but all of it is not real, fantasy is nice and fun but it's fantasy for a reason. |
