when something is moving at the same velocity as you, it appears to not be moving. then if something is aging at the same "rate" as you, wouldn't it appear to be frozen in time? consider special relativity: is it fair to say that at either extreme you basically are either travelling through space relative to another object, but not time (at the speed of light, as photons don't "appear to age" from our perspective); or travelling through time as compared to another object, in which objects appear to age? bonus: if everything in the universe began to move away from you near the speed of light, it would appear to be nearly "frozen in time" (everyone else's watches would barely be ticking) but if you flew off at the speed of light relative to everything else in the universe, everything else would seem to zoom forward in time, but whats the difference in terms of motion? does anyone have anything that could help me understand these concepts better?
