You lose a leg in a boating accident and 10 years later they invent time travel. You travel back in time (one way only) and tell yourself not to go on the boat that caused you to lose your leg. Your past self listens to future self and avoids the boat.

The outcome of this action would be:

1. Your future self would immediatly dissapear as without the boating accident you would never travel back in time to tell past self about the accident. (Looper, Back to the Future time travel ideology)

2. You would not have the accident but your future self would be stuck in the past without a leg for the rest of time. (Terminator time travel ideology)

3. You would lose the leg anyways. Without the boating accident your future self would never go back in time, and since that has to happen you have to lose your leg. (Timemachine time travel ideology)

4. Other - please explain

4. You can't travel back in time.

Special relativity alows it :P

OT, this is the classic time paradox. There is no way to know what will happen, the universe might implode for all we know. Most theoretical physicits see this as general and special relativity being flawed and incomplete theories for allowing such a paradox. Others patch the theory with the parallell universe hypothesis, that says that if you travel through time, you'll end up in a different universe, and thus your old self is still allowed to exist.

As long as you get all of the 7 chaos emeralds, you will get the best future possible.

Wouldn't that be time stones? :P

BTW, I edited my above post to include an answer to your topic.

You missed the other big theory, which is the "Split timeline" theory. Another timeline is created upon point of changing the original, allowing both possibilities to exist. (notable examples are Dragonball Z and Ocarina of Time)

I agree with wfz, I don't think traveling back in time is possible :p

number two, with the split timeline where no otherself goes back in the past and you can give yourself a handjob or whatever ( it's not gay, it's masturbation)

Bet reminder: I bet with Tboned51 that Splatoon won't reach the 1 million shipped mark by the end of 2015. I win if he loses and I lose if I lost.

People alwqays view this as paradoxal. Because, in appearence, when you arrive in the past, the machine or mean by which you travelled there wasn't yet invented and may not be in the time it was when you originally traveled. If you go back in time, You go back to a present in which nothing that came after ever happened. Since the first time it happened, you weren't there. Your presence there already changes the state of that point in time (think butterfly effect).

So your time machine, or whatever the mean used to travel in time is an anachronism. But that would be seen as such only to those from that past age. For you, you're still stuck in the reality, with its sets of laws. You wouldn't start aging only when the years finally reach the year you left from, would you?  Now, If you influence past events, leading to an impossibility for you to even exist in the state you arrived in the past, it won't really change a thing at all, since biologically speaking, you are still what you are because of what you experienced in your life. Your memory may end up being the only thing that proves what you went through. But I don't believe the universe will try to balance things out, or collapse on itself because your presence in the past can be viewed as a paradox. That the sensible world around you is aware of it or not, you still went through the experiences that lead you to time travel in the first place.

Here's a quote: ‎"Think of an experience from your childhood. Something you remember clearly, something you can see, feel, maybe even smell as if you were really there. Afterall, you were there at the time, weren't you? How else would you remember it? But here is the bombshell: you weren't there. Not a single atom that is in your body today was there when that event took place... Matter flows from place to place and momentarily comes together to be you. Whatever you are, therefore, you are not the stuff of which you are made." -Steve Grand"

If time travel ever exist, a paradox could never be, because the point in time where you would arrive would start a series of events that'd lead to you actually travel back to that point. Like, if I take your example, the very first time you were to lose your leg, you wouldn't have, because your future self would have already been there to prevent you from losing it.

But now, why would you have gone back to time in the first place, then?

You wouldn't.

If you look at it by drawing a straight time line, putting events in sequences, you notice that the point at which you arrive in the past isn't part of a progression, but a simultaneity. The very first time that this given event happens, you and your time-traveling self are already both there. The event from the past, and the presence of your future self in that same moment are both part of what shapes the moments onward. You were there twice during those events. So the event that you describe, traveling in time to prevent something from happening is impossible. It would already have happened as if you prevented it in the first place. In fact, "prevent" is not the right word. The events would actually have happened this way, since you were already there from the future. You can't change what happened, since you were already part of that time line's conditions.

This reminds me.

5. The timeline splits into 3 areas. One where your leg is still chopped off, one where you saved yourself, and one where you BOTH DIED while trying to warn yourself (for no reason other than wanting to create a third timeline).
