But if you hadn't come back, I wouldn't have been born. But I *was*
born, proving that time travel does exist.
In any case, since you alrady will have been born it's already too
late to have killed your grandfather.
I love you dad!

jenny I am sorry but if you were to go back in time then no the
person would not have been born but what you were saying was
making no sense whatsoever.
and as I already stated once you have used the "energy" of a time
frame you cant go back and visit that frame again
Don't be sorry. You're just a little confused.
If someone goes back and kills his grandfather then I suppose he can't
be born again. But the simple fact is that he must have been born or
he couldn't have killed his grandfather.
The facts speak for themselves.
================================================
Indeed they do. If someone goes back (in time) and kills his grandfather
(before his grandfather sires his father) then he can't be born the first
time, never mind "again". That is the nature of paradox. One cannot
transmit information to the past without it being paradoxical, or I would
have done so. (The information is "how to transmit information to the
past".)
There was a sci-fi story of a time traveller that visited the past and
impregnated a woman. He then leapt to the future, underwent a sex
change (complete, this is supposedly possible in the future) and returned
to the past where she/he lived out the rest of her/his life. She meets a
man and became pregnant by him, but the man she met was herself and
the child she gave birth to was the man that first travelled to the past.
The story is an anti-paradox of the grandfather paradox, he is his own
father and mother and therefore came into existence spontaneously.
An amusing read, but nothing to do with science.
