If i were to go back in time and find myself then, then came back to the present, would there be two of me?

Question

this is just something to ponder really, tell me what you think im interested.

Answer 1

No. One of a kind is enough.

Answer 2

I am guessing here that you mean you went back in time and then BRING your past self back to the present with you, is that correct?

(To make the explanation more understandable... I will use two dates - just for argument sake - You are here in 2007 and you go back to YOU in 2002. )
The moment you (the 2007 you - the one that goes back in time) arrive back in 2007, the 2007 YOU will cease to exist. Because the 2002 YOU has come here without living the past (2002 - 2007) so there will never have been YOU here in the present.

But then some might argue that - if the 2007 YOU cease to exist then there is NO one to go back to the 2002 to get the PAST you.
However, that IS possible when we talk about time travelling. By changing the past you have altered reality to a different "present"

However, I am not going to try to explain this as I will readily admit now that I will not be able to articulate it well enough and it will only sound confusing. But the best explanation of this is actually in the movie "Back to the future".

Well... this is what I think (as you asked for)

Answer 3

Normally I don't use science, but since we're talking about time travel (which is science), I'll make an exception...

Scientifically, if you went back to the past, an equal mass of matter would have to come into the future. If that amount was even a single molecule less than what went back into the past, the universe would change entirely (all objects attract each other, Universal Law of Gravity or something like that..I forgot). If a meteor would miss the earth in 1980 and you travel back to 1979, your body could change the course of the meteor and destroy the earth by just being there for a second!

Also, philosophically speaking, imagine that you went to 1930 and killed Adolf Hitler. You completely changed the course of history. If time would allow you to travel through it, one person travelling through time, if even the smallest rodent saw you, the whole universe would be ruined. The universe would already be destroyed if time travel was meant to be invented in the future.

Answer 4

The distinction between past, present, and future is only an illusion, however persistent.
There is no such thing as an absolute past, present or future. All are relative to a particular observer. An individual's memory of history, perception of present, and future destiny are all defined in their time-stream. As long as the time-steam is not interfered with, none of this will change in an unnatural fashion. Irresponsible time-travelling may interfere with any number of time-streams, regardless of how remote the interference seems. Time-streams belong to every space-time event in the universe, not just living sentient beings. However, for the purposes of this manual the term shall only apply to sentient beings.

To a single observer, the past is history: that which has happened. The present is the here and now: the events immediately happening. The future is what is yet to happen. Yet all are illusions of reality. However, all is not lost. We may apply these terms to an individual's time-stream. Within that context, the illusion becomes real, if ephemeral. Imagine a long winding stream of water, a river, stretching from infinity to infinity. Picture this and one pictures their time-stream. Now imagine a powerful wave of water, travelling along this stream. This is an event wave, a temporal signature, the exo-space-time definition of an event. This wave is an individual. As it sweeps along the stream, the crest of the wave represents the present. The stream behind the wave, which the wave has passed by, is the past. And the parts of the stream which the wave has yet to reach is of course the future.

A clarification is required here. The time-stream is not a history of the universe. It is the history of one space-time event, one individual. That person's past is defined only for them. Someone else's future may be that person's past. Such is the illusion of time.

Within the causal event horizon, every time stream interacts in some small, often insignificant way. The causal event horizon is basically the obersevable universe from the viewpoint of the time traveller. Time streams interacting is in itself not dangerous, nor is it avoidable. However, there are situations which much be avoided. At all times one's own time stream must not loop back on itself. This prevents one from meeting oneself. This is the first law of time, and the TARDIS will not under normal circumstances allow this to be broken. Even so, it is a wise practice to keep a record of when and when one visits, and avoid these coordinates if at all possible. Indeed, if a previous spatial coordinate is entered, the TARDIS will add on the amount of time passed on board (TSET) since the visit to the destination coordinate.

There is no past.There is no future.Everything happens in the moment.Everthing happens in the now.

Answer 5

I don't think so. The only way there would be two of you in the present is if you brought your past self back to the present with you. When you travel back in time, there is no longer a "you" in the present, but rather two of you in the past. When you return, you are in the present, and the you of the past remains in the past.

Answer 6

technically it is impossible for the same matter to occupy the same space, but that only means that you can't touch 'you', but the bigger issue would be that of time distortion., if you, as you are today, is the direct result of that earlier 'you' going through the experiences (time line) "you" did, then by taking that earlier you out of that time line and not experienceing those developmental steps, would alter who you are today! Example, younger you experienced a new program that made you consider time travel after the point at which you snatched you away to the future, then it may be that if you never learned about time travel, you would not have asked this question, endevored to pursue it, and finally never snatched the young you, thus completeing a time loop that would totally and completely change your future.

Answer 7

the only way there would be 2 of you is if the guy from the past came with you when you returned to the present, you wouldn't leave him behind would you? but if you brought him to the future with you then he wouldn't live those years leading up to the present , so then you would cease to exist, so , don't do it if you want to live

Answer 8

There would be only one of you if you returned to the exact point in time where "you" went time-travelling back in time, otherwise if you returned to the present 30 minutes prior to "you" going back in time, there are two of you there.

Answer 9

Philosophically this is impossible.
Now in SF (read Asimov "The end of Eternity") it is possible under some conditions. But that's only fiction!
However, a common belief is in metempsychosis. Historically Pythagoras was the first philosopher to believe in it, he thought he was the fourth re)incarnation of a king Darius. Theoretically one could remember some of his/her previous life(s). Now if you know somebody who does, please let me know I would be very interested.
Another interesting concept is "universal consciousness". This are values, attitudes, behaviours etc. that you learn before you even breathe. By animals it's called instinct.

Answer 10

Nope. There would be two of you in the past. And one of you in the present.

Answer 11

Maybe there is an infinite number of you and your consciousness is just traveling through time leaving the old physical "you" behind?
