I understood time stands still at light speed. Time is a dimension. So in what dimension are these faster-than-light objects moving in?
It's my understanding that the whole "speed of light limit" thing was predicated on one of Einstein's famous thought experiments. Imagine you are
looking at a clock. You are stationary and the clock is as well, so that you can see the second hand sweeping. You are not moving, but the photons
are, at the speed of light relative
to you. Now you begin to move away from the clock at an ever increasing pace. When you are moving at half
the speed of light, the light doesn't arrive at your position as quickly, so you are seeing "older" photons from the clock, making it appear
move more slowly. If you are moving AT the speed of light, then you are traveling at the same speed as the photons, and you see no change, making the
to be standing still - you are seeing the same photons (NOT the ones coming off the clock at that instant), since you are
traveling at the same speed as they are relative
Some one, somewhere, made the bright leap that "time" was linked to YOUR speed relative to the speed of light, and that you are seeing TIME slow down,
rather than realizing that it's actually just the photons not catching up (using more time to catch you) to your relative position as you move.
Because of that thought experiment, I don't see an actual linkage of actual time as much as the appearance
that time has slowed down. The same
experiment, run backwards, would have you slamming into the photons faster and faster, making time appear
to be accelerating as you race back
towards the clock.
If you had a clock at each end of the journey, one would appear to be slowing down, and the other would appear to be speeding up, depending on which
one you were going towards. This is the same principle as the red shift - moving towards
and object (or it moving towards you) causes you to
meet the peaks of the light waves at a faster rate, making them appear to be shorter (higher frequency), shifting towards the blue.
I personally believe time is a more absolute dimension, appearances
notwithstanding. Appearances can be deceiving, relatively speaking. What
you see is relative to where you are, rather than what is going on where you are looking.
