Actually you wouldn't just disappear.
Your past self would come to your future time and kill you.
And then later the past self would get to that point and time and be killed by his past self.
And it would go on like this forever and ever.
It's pointless really.
In the end, you're the one who dies.
You might as well just not time travel and commit suicide right then and there.

If you were to travel back in time and kill yourself would you then dissapear, but I was thinking if you dissapeared then your future self never existed and since it was you who killed you in the past would you not be dead..... or something hopefully you can understand what I'm trying to say if not feel free to make jerky comments about this thread.
It would cause a paradox to occur because it makes no since and you can't really explain that kind of a situation.
And first of all the fact that you went back and interacted with you past self would cause a paradox, or like the in the back to the future movie, you could also just faint. But doesn't the sound of a paradox sound so much more fun and dramatic. I think so. So I'll stick with the paradox thing. A paradox would happen and the timeline would be destroyed also with the world as we know it.
So much more dramatic....................
According to physics, it is theoretically possible to travel backwards through time, but it would only be possible to travel backwards in time to an alternate dimension. Therefore, it is possible for you to kill a past version of yourself in an alternate universe, but this would not have an affect on you.
Hypothetically, if it was possible for one to travel backwards in time in his own dimension, it would be impossible for him to kill himself. This is because if his future self successfully killed his past self, his future self would not exist. Therefore, the fact that his future self exists to be able to travel backwards in time in his own dimension and attempt to kill his past self means that he can never be successful.

Agreed. Thats the only way to prevent those paradoxes.

what in the holy hell?
1. possible in theory.....with no possible practical application. To do so one would have to travel faster than the speed of light. As you go faster, your mass increases. As you approached the speed of light your mass would become infinite (which is why it's impossible for anything with mass to travel faster than the speed of light). To propel infinite mass you would need infinite energy. To propel infinite mass +1 you would need infinite energy +1, which is just ludicrous. It is only possible in theory........because in theory, we can just make up things like infinite energy and infinite energy +1........things that can exist in our mind where the theory is held but not in reality where we live.
2. where the hell do you get alternate dimensions? Science has never proposed such. you stole that from Back to the Future II.
---------------------------------------------------------------------------------
as I stated earlier, the entire concept is just ridiculous. To entertain such notions is however okay if you realize that it's just "what if?". Even then, it would require predestination........that everything that ever has and ever will happen in our universe was pre-mapped and could not have happened any other way.......which means there is no such thing as choice or free will. We are all slaves to a destiny which we can not control nor change.
If you went back and time and killed yourself, you would not disappear. It would simply be the pre-ordained way that you die, mapped out at the very creation of our universe. You were destined to grow up, go back in time and kill yourself. What of the world around you? It's of no consequence as we all see our universe from a first person perspective. Once you died in the "past".......you would simple be dead, that is all of our universe you could percieve.

1. I agree that modern physics don´t allow us to travel faster than the speed of light.
2.And yes, alternate dimensions was proposed by a physicist named Richard Feymann, and quite famous, his theory came from quantum mechanics.

pretty interesting 😄

yes......alternate dimensions......big player in the cosmic string theory also........that's not the question...so please don't explain something so pedestrian to me. The guy up there said that physics states "According to physics, it is theoretically possible to travel backwards through time, but it would only be possible to travel backwards in time to an alternate dimension."...............and I'd love to know what physicist master minds he has been reading that even mentions time travel, much less saying that it is possible but would take you to other dimensions......
Let's not take this too seriously.
Anyway. Like people say, anything is possible.
Who would of though all those years ago that we would be where we are today. The answer is a bunch of people pictured us being where we are, some didn't and some saw us even further advanced than we are.
So just like with this time traveling thing. Anything can happen and we will see it when we see it and if we don't we just don't.
And personally with all the risk that comes along with time travel if it were possible right now. I wouldn't want to do it and I wouldn't want anybody else to do it.
It's too dangerous and affects too many people.
I hope it never comes to exist.
But I wouldn't mind if there really were alternate universes, like on the movie "The One" with Jet Li.
That would be interesting to experience. To see yourself in many different forms and ways. And whatever you did in those alternate dimensions would cause a ripple effect that would affect the past and present and and everybody in them.

Hugh Everett and David Deutsch.
Hugh Everett and David Deutsch.
2 people state this.........not the laws of physics. they propose their ideas.......ideas of 2 people, not physics.
To dangerous?The past is written in stone, even if time travel were possible, there would be no way to change it.
exactly.......which is why for any time travel hocus pocus to work, it would require that everything in our universe is pre-ordained, fate, destiny, whatever you want to call it. A person could not go back and "change" something. For something to be percieved as being changed it would require that the "change" was already pre-ordained by destiny. You had no choice in changing it.......the universe was mapped out, you have no choice, you were going to change it regardless...........which really means it's not a change, it's only percieved to a person with a first person point of view as a change.
Anything can happen and we will see it when we see it and if we don't we just don't.
no. many things that sentence does apply to. there is much we don't know about our universe......our future advancement of technology may very well lead us to a greater understanding and general knowledge about our universe..........which may in turn lead to many things happening that we would deem impossible today. This however does not apply to the relationship between mass and energy required to move it. It's a very, very, very, very simple concept........one we already know all too well. There are no surprises in our future on this front. No new knowledge to be gained. For anything with mass to move, sufficient energy must be asserted to it. Any parapalegic can tell you that their legs cannot move because the nerves that transmit the signal to their muscles telling them to assert energy are damaged and cannot transmit the signal........and they need not to have ever even studied physics.
Yes I agree that time travelling backwards is not allowed by the modern physics, but it could be possible in the future if someon prove it. The alternate dimension theory is an interpretation of the quantum mechanics, and that theory eliminate all "closed timelinks" contradictions, but it not makes time travel "backwards" a scientific fact.

Your seriously wrong😄
A little on how it could be possible at least for atomic and subatomic particles
http://plato.stanford.edu/entries/time-travel-phys/#4
Quantum tunneling does not preclude time travel either😄

Like lets say I got back in time to meet President Lincoln.The night before the Gettysburg address I see him. He's having trouble trying to write the address so i write down the exact one i learned from my history book. The next day he says the address exactly as planned. Now who really wrote the address?It wasnt me I just took what I knew and gave it to him. It wasnt Lincoln, I gave him what he said.So who wrote it?
I hate this example.
It doesn't even pertain to what I said.
There are many things wrong with it that I could state but it's just too much.
