Okay before I drag out an old question I should let you know that according to science light in the form of protons has mass.
Anything which is inside another object which is traveling is traveling at the speed of the object in which it is traveling.
So, given the theory (and I stress theory) that nothing can travel faster than light, what happens when you turn on a moving car's headlights? Is the light, in the form of protons having mass, traveling at the speed of light + the speed of the moving car? Is it therefore traveling at past the speed of itself?

I know this sounds like a stupid question but I've never heard a satisfactory answer to this.

Also, in today's paper, scientists have postulated that the presence of a large body in space "warps" space and time around it. If this "warping" can be accomplished by a simple gravitical body could we not find a way to generate a field to "warp" space and time allowing an alternative to straight forward space travel?
