What car does the speed of light and at night time to? Little boy racer lol. I think the correct answer is the one that it would, because it is travelling from its source at a constant speed, and if the source (light on the car) is moving foreward at the speed of light, then the light will stil travel foreward.
As for the marksman, if he is falling to the ground from FL350 at the speed of a bullet, and fires a bullet from a gun, what ever good that would do to save him, the bullet will leave the gun at the normal bullet speed so to speak.So would it not exit the rifle at the usual speed, but because the rifle is doing bullet speed, it would appear to exit at twice the speed but only be doing its normal speed, it appears as two times faster as it is going x m/s that way < and we are going this way > at bullet speed?
Just a thought, keep these coming, very interesting to ask and pass time.
