One that travels back in time runs the risk of destroying their own existence which causes in turn them not destroying their own existence.

I simply cannot believe this is possible since accepting time travel will in turn mean accepting something like the grandfather paradox can happen.

Con

Suppose my grandfather has a son who is my father, and my father has a son who is me. We'll call this Reality A.

Now if i travel back in time and meet my grandfather before he has had a child, i would be alive before my father would exist . Since this does no fit with Reality A, We'll call this Reality B. So we can assume that actions taken in Reality B will not affect Reality A

Now if i don't kill my grandfather, we can presume that i will be able to witness my fathers birth, and then mine. If i did nothing and just observed there will be eventually two of me in the world. And then i would witness myself travel back in time. And he would witness my birth a third time, this process could continue for ever.

Now, if i do kill my grandfather, i would not disappear. i would merely watch the world, and never see my fathers birth, or mine. And there would be no additional me's.

I hope this is clear, if not sorry.

That's all assuming that the person reading this article believes in alternate realities.

Now if you believe the mechanics of back to the future(lol) then you killing your grandfather will result in you disappearing from existence.

My opponent says: "That's all assuming that the person reading this article believes in alternate realities."

Well is not the grandfather Paradox assuming there is only one Reality?

If i travel back in time and eat at a restaurant, or buy a pack of gum, is it the same reality before i time travel?
No, any changes i make to the past makes a new reality. Besides we are faced with the possibility of new realities every day. Do I go to the movies or not? Do I debate this topic or not? Our choices dictate what reality we will experience, but different realties could exist. There are multiply realities, but we only perceive our own.

in addition, the paradox uses normal logic to explain for a very illogical situation, does it not?

I guess so Josh.

But theirs still other problems with time travel like if their is alternate realities, then which do you go back to if you travel foward in time after having changed history.

Or If you introduce something from the future into the past and it in turn ends up KILLING EVERYONE ON EARTH. Would you then die?

No seriously I just thought of that one right now holy sh!t lol.

This reasons and more are why time travel couldn't be possible since itll alow you to kill yourself in one reality if you believe in alternate realities. yet live in an other.

How about if you(2008 5:30pm) go back in time to(1988) buy gum come back to the future(2008 5:35pm) go back in time (3 mins) wait for your past self and kill him at (5:35pm). wont that mean you killed your past/future self???????????????

I'm sorry but vote PRO time travels just not possible at least to the past.

My opponent sates:

"But theirs still other problems with time travel like if their is alternate realities, then which do you go back to if you travel foward in time after having changed history."

The one you were currently existing in.

"Or If you introduce something from the future into the past and it in turn ends up KILLING EVERYONE ON EARTH. Would you then die?"

Well if it kills every one on earth, and I am on the earth then of course i'll die.

"This reasons and more are why time travel couldn't be possible since itll alow you to kill yourself in one reality if you believe in alternate realities. yet live in an other."

Ok. i don't really understand your argument.

If i was trying to run a red light there are two possibilities that could happen. i would safely make it or i will die in a car accident. the two different realties that would come of this would be 1 where I'm alive, and another where i'm dead. time travel is wold be myself from a different reality effecting another,

well, i hope you votes CON because i have proven a type solution to the grandfather paradox.

I think there may be a difference between different "realities" and different "dimensions". Is not realty a perception of ones surroundings and experience? People all have different realities but we all live in the same dimension.

Time travel takes place within ones own dimension and therefore the actions that have happened in the past have already taken place and are established. If something interferes with what has already taken place, it would alter the surrounding and later actions of everything along that action path.

Time is just an idea, you cannot feel, taste, or touch time.

You can alter a clock, or the world can change what time zones are what. Travel back a few time zones.

You cannot travel though an idea though. Time technically does not exist. Only our clocks that represent this idea.

You cannot travel forward into something that doesn't exist yet either.
Unless your one who believes in our paths already being chosen.

All those paradoxes could be bypassed if you stopped assuming that there's only one reality.
