I've always known Einstein was wrong about time travel but I never felt I had the time to properly debunk it.
So tonight, I'm eating Ben & Jerry's "coffee heathbar crunch" icecream and a simple answer to the problem presented itself
The theory is that if you could travel at faster than the speed of light, you could travel through time. Here is why its wrong:
Time has no relationship to people. Time passes regardless of what a person does.
if something happends in another galaxy and it takes a year to see it because the light is traveling from so far away, by the time we see it, its already a year old (standard stuff)
But if we travel at faster than the speed of light towards that galaxy, we will get closer to seeing the galaxy in realtime. we will NOT be turning back the clock.
The proof of this is our ability to travel faster than the speed of sound.
If a sound takes 10 seconds to reach our ear because the action creating it was so far away, we hear an action that happened 10 seconds ago. Not unlike seeing something from the other galaxy that happened already.
Now, if we travel at the speed of sound towards the action that made the sound, we DO hear the sound sooner but we do not travel back in time.
Swap speed of sound with speed of light and you see why Albert Einstein is wrong.
