: Is time inversely related to the speed at which you are moving? Does time pass quicker when you're moving slowely than it does when you are moving close to the speed of light?

: Another question, do electrons move around atoms faster in gas than in solids? and, do they ever reach near the speed of light? i know they can't reach c, but as they get closer, does time slow down for them?

: Then again, what would they be moving at light speed relative to? I mean, we're probaby traveling at the speed of light from somethings point of view... i mean, if we were traveling at half the speed of light, and something else was traveling at half the speed of light, wouldn't it appear to them that we were moving at the speed of light?!?!? Oy, my head hurts...

I think you should try to get hold of a book on SPECIAL relativity. The transformations of time, etc. are measurements an observer sees of moving clocks (slow down), moving objects (get shorter and heavier), where these changes are described mathematically by the Lorentz transformation.

The question about electrons in gas vs. solids is complcated, since in gasses, they are associated with individual gas molecules, while in solids, it is a lot more complicated. Ordinarily, however, they do not go anywhere near the speed of light. Physicist have tools (particle accelerators of various sorts, where electrons or other particles are accelerated to close to the speed of light, where the speed is relative to the lab. Time does slow down for them.
