What would happen if you killed yourself in the past?

Answer 1

Supposing that you found a way to travel back in time and killed your past self, there may or may not be significant repercussions.

Firstly, one must consider the concept of time travel. Time travel in itself is a isolated experience. If you traveled back in time and changed the world's course of events, when you came back to the future, the only person who would know of the changes would be you since you were the only person to have experienced an original and alternate reality.

This concept serves as the basis for the next assumption; if you traveled back in time and killed your past self, 1. it would have different effects depending on how early you killed yourself, and 2. would effectively erase your future self.

If you killed yourself as a baby, or very early into your life, it would have less repercussions because you would not have as many connections with other people.

If you killed yourself later in life, it would appear to have been a murder since the time difference would contribute to you looking dissimilar to your younger self. When you kill yourself, theoretically, you would die and then disappear because you would have erased your existence.

I guess you wouldn't be alive today???

P.S. How would you even get to the past?

This is an example of a paradox. They sound almost sensible but with a little thought you can see they are ridiculous, self contradictory and just go around in circles in most cases.

If you went back in time and killed yourself then there would be no one to go back in time to kill you so it could not happen.

I dont think It is possible for a human to travel back in time.WHY?Because if your future self did not exist in that time it so is not possible for you to exist in that time-space reality, because you never existed then.You traveled in the past and your past self never experienced your future self in the past so therefore it would not be possible.And if you did it would probably rupture Time-Space reality.

My answer, nothing would happen to the you from the future.

This is because it's impossible for you to just disappear. It violates the laws of physics.

The moment you killed yourself in the past, you rewrite the following years. Say that you stop a man from committing suicide in 2009. Then later, in 2010, you travel back to 2008 and kill yourself. The man you would have saved in 2009 actually commits suicide.

Now, what happens to you, however, is a bit more complicated. You (The You from the future) will still exist after you kill the you in the past. The reason, the moment you travel back in time, the timeline you know is rewritten to compensate for your actions. However, you from the future is an exception. Since you had the good fortune of being in the past during the events, you will not be rewritten along with the rest of the timeline.

There isn't a split in timelines, just the rewriting of one. And somewhere along the years that follow, a very lonely time-traveler that shouldn't exist does.
