Physics, Astronomy & Cosmology / Speed restriction for light?
« on: 05/04/2008 16:50:20 »
Hi,
This may be a silly question, but I think it will help me understand a whole lotta other things...
I understand that the speed of light (C) is the ultimate speed limit in the universe. Now, if Im driving along at 100km /h and I switch on my lights will the speed of the light emitted from my headlights be c or c+100km/h ? If its just C then what is the factor that causes this limits and what happens if I watch a spaceship travelling at c - 100km/h with its headlights on??
Thanks!
Jim
