Suppose we have two spaceships a lightminute apart from each other. Ship A sends a photon to ship B. To my knowledge the photon will arrive at ship B a minute after is was departed from ship A.
The photon will travel away from ship A with speed c, and will travel towards ship B with speed c.
Suppose that ship A will start moving away from ship B a relativistic speed ten seconds after it sent the photon. What reference does the photon have to determine its speed? It should keep moving toward ship B with speed c, and it should keep moving away from ship A with speed c, but the photon wouldn't keep track of where the spaceships are, right?
