if it was possible to travel in time and you travelled 15 years back and killed yourself?

Question

what would have to the "you" that has travelled 15 years into the past?
would it disappear?
would it be possible to do so, if you are killed when you are, let´s say 15 , it wouldnt be possible that a yourself of 30 killed yourself (man, i think this is too confusing!!!!)

what would happen to the you..., i meant

Answer 1

Well.... You might create an alternative time line. That means a branching of realities so that two parallel realities exist.

Answer 2

OK, lets look at it this way. You say that your 15 yo self "can't" be killed by your 30 yo self because you won't had been there to turn 30. This is logical. However, the concept of traveling through time is not a logical premise. It's like saying God couldn't have created the world in 6 days because He wouldn't have time for all the paint to dry. If something is a miracle, all bets are off. If you have time travel, all bets are off. In the end, you would be alive and dead at the same time. Joe

Answer 3

You would be changing history which means your 30 year old self would disappear, but at the same time you would have caused a tear in time and space and there by would have destroyed the universe. You killing a younger version of yourself would be like creating a black hole.

Answer 4

Everything would just 'not exist' anymore. I mean, in fifteen years, a person meets lots of other people, affects their lives somehow, affects nature, and these people affected affect other people, and these affect other people....... it's almost endless. That's why it can't be done, because the world would turn into a chaos. Everybody would change history every second, so there would be no history at all. If you went back fifteen years, the 'you' who went back would not exist, and consequently, would not go back fifteen years and kill yourself... it's nonsense!

Answer 5

Depends, some physicists would say that either way, the dimension your original 30 year old self lives in still exists and thus, its past of your 15 year old self still living, would remain existing aswell.

Others like Ray Bradbury would say any transgression one makes in the past will, according to the butterfly effect, some how impact the present day in one way or another.

Answer 6

There are at least three possibilities.

1. you cease to exist
2. you find it is simply impossible to kill yourself
3. the act of killing somehow transports you to a parallel universe where you killed yourself, but your past still exists in the time line of the universe that the killer-version-of-you came from

Answer 7

You could not travel back as you would be dead. To recall 15 yrs would be impossible! Why,because you died at 15

Answer 8

Tear the space-time continuum no doubt. But not by much.

Answer 9

I with bxxdy on this one.

Damn elegant explanation.

Answer 10

Just don't drink anything tonight and you will be okay later.
