Aberration Angle; Moving Observer; Speed; Special Relativity; Velocity
An Observer moving with velocity v, relative to a source of light moving with velocity u, sees light coming at velocity s = c + u – v, where c is velocity of light, a vector of magnitude c. The speed c is a universal constant relative to the source only. For observer moving with velocity v, relative to a stationary source, light comes with velocity (c – v), at aberration angle a between the vectors c and (c – v). In motion away from a stationary source, speed of light is (c - v), toward the source, speed is (c + v), round the source, at right angle to ray, the speed is (c2 + v2). Speed of light may be exceeded, relative to a moving observer, contrary to the relativistic principle of constancy of speed of light.
