Time Travel is Impossible
I read the whole thread on time travel and figured nobody is going to look at the very last post and the only way to get anyone to look at my opinion would be a new thread. So here is why time travel is impossible, at least into the past, improbable to go into the future.
You cant travel faster then light because even if u are going the speed of light then light, relative to u, is still going the speed of light therefore u cant exceed it. So that sort of answers the question "what happens if your going the speed of light in a car and u turn on your headlights."
Now here is why u cant go into the past. Picture a 1D line, it makes no shadow, now a 2D square, it makes a 1D shadow, now a 3D cube, it makes a 2D shadow, now the 4th dimension, does it make a 3D shadow, yes that shadow is the past, now tell me can we get into our own shadows... personaly i think going to the past is impossible since the past is the shadow of the fourth dimension and living beings generate the 4th dimension since its been proven that farther away from Earth time is slower, hence the atomic clock experiment being sent into space and it came back a little bit off from the other atomic clock.
