Well heres a question I really want to get answered or if there is even answer to it. As you all know the grandfather paradox is when the son of a father travels back in time to the fathers fathers time and kills his him would he still be alive in future even if does return or would he be dead or out of existence. And thats before the grandfather conceives with the grandmother. But what is the son impregnates the grandmother would his genetics interfere with the dads genes making him completely different would the result be the same? Then he goes back in time to himself (the one who impregnated the grandmother and returns to see him) would that also change the flow of time for the genealogy of the family.

Assuming time travel is possible, you'd have to know if traveling through time would mean staying within the same timeline that you exist in, or traveling to a parallel universe. If it's the parallel universe, killing any ancestors would have no effect on you personally (although you would prevent another you from existing in that universe - as well as several other relatives). But you would indeed be killing yourself if it was your own timeline.

Even if it is your own timeline, it might not make a bit of difference. What if you can't do anything in the past that hasn't already been done by yourself in the past? Clarification: in your timeline, the "record" and effects of your timetravel there already existed. I believe this to be the most probable of all scenarios.

I don't think it matters until we are put in a position to achieve that technology, at which point we would probably know the answer.

No, this is not theory, this is amateur speculation.

AntiSleep is right. False implies anything. Since time travel is impossible, going back in time is false.. thus implying Bush is awesome. LuL. Learn logic guys.

oh sure you can go back in time, but what ever you've done there has already happened so no matter what you do you've already done it. Because those decisions were already prerecorded by yourself. So in other words, you couldn't go back in time and kill your great grandfather.

AntiSleep. Read: http://en.wikipedia.org/wiki/Logical_implication Until then, don't try to pretend like you understand logic. Because you don't if you don't even understand implications.

I understand implication very well, but you do not. I implied that we are currently not in the technological position to create a viable time travel machine, I did not imply that time travel is physically impossible, because I do not know if it is(Current hypotheses suggest it isn't, but require the storage and manipulation of antienergy).

If you understood implication, you would know that F --> Anything. Hence my Bush comment.

No. It doesn't. The truth table for implication is: A B A->B T T T T F F F T T F F T

Way to hijack the topic, seriously. I think... That the assertion that you can't do anything because it is already done is junk. Here.... If you go back in time five minutes and go to the place you were five minutes ago, you will find yourself five minutes ago. Notice, there are two of you. These two are completely independent past the point of your arrival in the past. Go back in time to your grandpappy's day, and you will still exist, regardless of what you do. However, the you from the past, not so much. If you were to do something that killed your grandfather, and waited (or traveled through the future) until the time of your birth, there will be no new you. The insertion of your mass and energy (which violates the laws of thermodynamics, by the way) into the past WILL affect the future. Waiting for or going to the future, you will always find a different future. In fact, every single piece of matter in the universe is different, because of gravity, and any quantum affects that may have. Any perceived similarity is purely coincidence.
