Hi,
Well...the general idea is that time travel is usually not possible because of paradoxes such as those. However, there is at least one scenario in which it may be possible. Say you go back in time (about five years) for the sole purpose of killing yourself. So you're sitting (with your sniper gun) in the top story window of a building across the street from a bank. You are waiting for your "then" self to walk out of the bank so you can kill your "then" self. When you see your "then" self, you take aim and fire. But you miss killing your "then" self and instead you shoot your "then" self in the arm...Now you would have made the shot, if it wasn't for your bum arm, which you got five years ago when some sniper shot you in the arm while you were walking out of a bank.

What you are referring to is called a causality violation paradox. You must be feeling particularly intellectual today, because this concept has caused the great scientists of the world to scratch their heads for many years.
The most frequent example to argue against time travelers tampering with the past is the continuing historical reign of terror of Adolph Hitler and the Third Reich. By now, scientists reason, someone would have kidnapped him at birth and put a stop to the Holocaust, and yet it remains etched in history.
The argument brought forward to explain the tampering such as the girl that goes back in time and kills her own mother, is that this becomes an alternative or parallel time line, and we would have no awareness of any material change in our present time line.
People that dive into time travel live in a world of whirling universes and dimensions that are very theoretical and abstract. Do such parallel time lines exist? People that dream about time travel certainly hope so, because it is the only way to explain away the paradox that you have so brilliantly brought forward into our humble forum.

One possibility is that you can never do this. Your existence may include you going back into time, but something would happen that thwarts your effort. Your existence is a given and includes your time trek as well as your failure.
The other possibility is the sum of all histories philosophy. You end up travelling through spacetime into an alternate universe where that version of your mother has an existence which ends with your killing her.

That would be a paradox. Yet its a theory.
another theory states that by simply traveling in time you change of timeline, therefore killing your mom in another timeline, but the mom from the original timeline would still exist. therefore you will continue to exist .
Remember not to touch anything and do not make yourr mom fall in love with you or anything like that , and wear a seatbelt too

You would soon figure out that you killing your mom or whatever doesn't solve anything and if you did exist after the killing you would miss your old life so then you'd go back and change it and just be happy with the way your life is/was.

When you killed the mother, It put you and her out of existance. Just because you are now out of existance, doesn't mean the mother came back into existance. So the chain stops when you disappear.

There are two theories to time travel.
Linear: What your stating (also seen in Back to the Future)
Parallel: In this concept you are going back to the day you mom was a child but to another dimension, which is almost exactly like this one with one change, your back in time.
The theory basically says that for every combination of every action there is a dimension.

Have you ever heard the theory of parallel universes. This is a real theory. Anyway if one travels back in time and kills their mother, they create a seperate parallel universe where they were never born.

Dont touch anything and get back as quick as you can, killing your own mom or anybody, or anything for that matter could have adverse side effects. The entire world could be different if you killed only one person/thing.

Time exists only in our minds and so do concepts like past, presence and future, and so this question is nothing than a play with words. Sorry Dude, no time travel....
