Is the butterfly effect in play or does the timeline have some kind of inertia? What happens to the previous timeline?It seems that time travel could only work by sending things into the future instead of the past. If you sent stuff into the past you would always get the result where you sent stuff into the past to correct the problem caused by sending stuff back into the past the first time.
For instance, suppose you went back into the past to kill Hitler. It should be obvious that whatever you did didn't work because you had to go back into the past to kill him again. Besides, if you were able to do such a thing then chances are you and countless millions of people wouldn't have existed.
Everything we have right now, including our very lives, we owe to Hitler's existence. Therefore it would be a tragedy for all of us if he had been killed as a baby.
