Time Travel

[Mike Donoghue]

I've got some food for thought on the matter of controlling the passage of time around you (like in movies), although I'm not sure how it relates to worm holes and the like. Here it goes: temperature is a measure of the average kinetic energy of atoms, molecules, etc. in a specific region of space. If time were to "speed up" around you, the motion of things would also increase, thereby raising their temperature. Well, if time were to "freeze" around you, then everything would suddenly fall to absolute zero! This thought experiment is actually what got me interested in physics when I was a little kid. Anybody know if that is actually the case for time dilation?

If only 'time' was a physical medium, maybe we could figure it out. But tisnt, so there's nothing to get hot or cold about it. Apparently, though, time dilation kicks in at less than the speed of light. Maybe someone can explain that, but it won't be me. )
