on the tv earlier, they were talking about time travel... and saying that if a train were to travel round the planet at a speed of 7 times round Earth per second (i.e. almost the speed of light), time would slow down inside the train.... they said that the reason time would slow down is because physics says that if a young girl were to get up and run down the train, she could, inadvertently be travelling faster then the speed of light .. which as we know is impossible.
However, what it the girl was on a motorbike in the train? ok, so probably not gonna make a difference? but what if somehow, the girl was on the train travelling at 99.9% the speed of light, but within that train, on another train travelling at 99.9% of the speed of light?
how does time know just how much to slow down?
