Question: Two space ships are in an epic dual, flying towards a worm whole. Ship A is closest to the whole and is moving at a speed of 0.7 c toward the space anomaly, the other is catching it at a speed of 0.8 c. If ship A fires a laser beam of high energy photons at the chasing ship, how fast will the second ship see the laser coming towards it? answer should be 3x10^8 m/s but how do you get to that answer?
