we know that the speed of light (C) is effectively a cosmic speed limit and so if a ray of light was shone from a moving ship in space it will still travel at that speed and time will slow down relative to the ship(although they would not perceive it). so the ship would still accurately perceive the speed of light from that ray. (thanks einstein

my question is what would happen if 2 beams of light were shone in opposite directions, perfectly parallel to each other, from a stationary object in space. what would happen? how would they not exceed the speed of light relative to each other? the only thing i can think of is that the time of the 2 individual beams would slow down by 1/2 so that they would be traveling at the speed of light relative to each other, but wouldn't that cause them to no longer be traveling at the speed of light relative to another object? or would that be just how its perceived by that object?
