Re: Faster than light

You cannot rotate the torch faster than the speed of light. The emission of light is at the speed of light.

So you effectively have a spiral of photons/waves travelling away from you at the speed of light in a spiral (if you span 360 and not just across the wall).

The question is, do any of those photons/waves appear to be travelling faster than light from any perspective/trajectory? Einstein would say no and I assume it holds. I'm just not smart enough to do the maths just now though.
