If time travel were possible, and I went back in time, and attempted to kill my grandfather, then my father wouldnt be born, therefore I wouldnt be born, and if I am not born, then who was it that went back in time and killed my grandfather? It is then assumed that something will always happen to stop me from killing my grandfather, that means that no one has any FREE will, and everything is preordained? If this is so, what is the larger intelligence implementing these prordained occuranances? God?

Secondly, Leonardo Da Vinci was said to have some ideas on machinery that was unusually ahead of its time, it was said that someone from the future gave him these ideas. If someone 500 years from now travels back in time, and shows them these machinery designs, how can they exist right now if no one has gone back yet? How can something have already happened, and had not happened yet, at the same time?

If time travel were possible

then everything you're saying is false.

No it isn't.

Face it - as soon as we stop working on ways to blow each other up, someone is going to stumble upon time travel.

I mean, we are already getting somewhere with it if you were to look up some info on discovery channel and such.

And yes, I believe its god who predetermines everything.

yeah whatever....whatever.

which means that "Future Us" has already had infinite chances to rectify any mistakes.

It doesn't matter how large or multifarious the number of actions "Future Us" wants to take, because all of those actions can be taken.

Thus, it can be inferred that "Present Us" is living in the most perfect timeline that has been possible

Even if there were multiple groups working towards different ends, each group would still have had infinite chances to impact the past.

So take, for instance, the Cold War. One group argues that the United States should have simply bombed the Soviet Union and China to save all the unnecessary loss of life that was directly or indirectly influenced by the strict tension. Another argues that more attempts at peace-talks should have been made to remove said tension. Another believes that they should have allowed Hitler to further ravish the Soviet Union during WWII to prevent their early acquisition of nuclear weapons.

It doesn't matter how large or multifarious the number of actions "Future Us" wants to take, because all of those actions can be taken.

we exist in a whirlpool of correction where the only constant is change, and where we're approaching perfection at an ever-increasing speed
