i'm a little lost here. how does time dilation work again? i can't seem to grasp how someone can "see" time "dilating".. pretend you have two synchronized clocks doing something different for a while, and you come back and put them side by side. if they're sitting at different times - one is ahead of the other - why all of a sudden does this mean time has "dilated"? no matter what you do to the two clocks, you don't change the time - the reason for the different times is because of things happening to the mechanisms that run the clock, not time! anyone??
