Consider two spaceships, each traveling at 0.50c in a straight line. Ship A is moving directly away from the Sun and ship B is approaching the Sun. The science officers on each ship measure the velocity of light coming from the Sun. What do they measure for this velocity?
A)Ship A measures it as less than c, and ship B measures it as greater than c.
B)Ship B measures it as less than c, and ship A measures it as greater than c.
C)On both ships it is measured to be less than c.
D)On both ships it is measured to be exactly c.
