1.	Let there be a hypothetical vehicle/spaceship traveling at the speed of light(c). The headlights of this spaceship are turned on which emit light. What will be the speed of light from the headlights (a) from person sitting inside spaceship's frame of reference (b) a nearby observer at rest. c =3× 10⁸m/s (approx.)
Answer» tion:No. As OTHERS have explained, you cannot exceed the speed of light. In one dimension this PROHIBITS your light speed car from SHINING at all, because the light cannot move faster from the car, and so can never leave the HEADLIGHTS. However, we LIVE in multiple dimensions and so not all light shines in the same direction.Let us set up a 2-dimensional, massless (i.e. moving-at-lightspeed) car that fires off two photons, one going up and one going down
