So if the spaceship is fitted with a powerful laser-beam and is shooting at a target (enemy mother-ship that is sitting still), and I am observing from afar, will the spaceship see the laser hit the mother-ship before I would observe it hitting the mother-ship?
So, if I have a second spaceship and I speed up to 100,000km and back down to zero, as I observe the light from the other ship, it will always be C? I thought light was constant only in it's local reference frame.
If light travels at a certain speed through fiber-optic cable, would the light get to its destination faster if the fiber-optic cable was actually a liquid, and the liquid had a substantial velocity in the same direction as the light?
