Imagine that from a spacecraft moving relative to the Earth at a speed equal to half the speed of light, light is emitted in the direction of the spacecraft. What is the speed of this light relative to the Earth?
The speed of light does not depend on the speed of the source and the speed of the receiver, it is the same in all inertial reference frames, so the speed of light is c.
