well i'm not sure, but i think u're talking about the Grandfather Paradox.here it is.Suppose u have a time machine and you are feeling a bit mischievous.So u think lets go back to the past and have some fun.you go back to the time when your grandfather was very young and your father was not born at that point of time.What you then did was u killed your grandfather(don't take it offensively, i'm just telling u a concept, i'm not suggesting that u did it). now you just killed your grandfather at such a time when your father was not conceived.this means YOU were not born. And if you weren't born, you CANNOT go back in time and kill ur grandfather. but then you DID kill your grandfather didnt ya, thats why you weren't born.this is the paradox.one explanation that has been suggested to explain this is the concept of parallel universes.according to it, you did go back in time and kill your grandfather, but in another universe, so whatever changes you made in that universe, dont show up in this universeits a bit tricky, time travel, some things baffle you, this paradox is one of those things.

hiiii

'Time Travel paradox' which goes something like this :Suppose a person travels to a time before she was born and breaks a causal chain that led to the traveler's birth. This problem has been commonly explored by asking 'What if you killed your own grandmother before she first conceived?' (Curiously the problem is never expressed in terms of killing your own mother). The apparent paradox is then of a logical sort: P entails NOT P and NOT P entails P. If you kill your grandmother then you would not be born, which in turn would bring it about that you not travel into the past, thus you would not kill your grandmother, thus you would be born causing you to again travel into the past to kill your grandmother !!!!!
