suppose we use a machine that can fire two lasers at opposite direction at the same instant
after 1 second the one laser would have traveled |C| distance to right
and the other laser would have traveled the same distance to the left
so from the lasers point of view the other one in moving -2c m/s in the opposite direction right?
