@david-burton saidNo. Go check out the word "Relativity".
so let me get this right if you are driving your car at the speed of light and you turn your headlight on ......nothing happens ?
@david-burton saidGravity bends light. The more gravity you have, the more the light bends.
so if light has 0 mass why cant it escape a black hole? and surely sun rise is the motion of the earth not the sun actualy moving or amI wrong?and light even with 0 mass can be bent in a vacum.
and
Light doesn't need a vacuum to "get bent" (refract).
@suzianne saidgravity cant bend light it bends the space/time and refraction kinks light not a bend.the earths atmosphere actually slows light down.but because a photon has 0 mass I am not sure why.light travels slowest through diamond.and the universe expansion is traveling faster than light.

-Removed-So at least in Germany "Sonnenufgang" is defined, when you observe the sun coming over the horizon, that the incoming light is actually a bit dated at that time is not of relevance.
Since the sun is emitting the light in all directions (quai) homogenously. The light is alredy 8 minutes travelling, but is arrives directly at the sunrise time.
@drewnogal saidand a budding alchoholic..... well in my past maybe.
Nice to see there is an alchemic among us.
@very-rusty saiddid you know light is lighter than dark.
How fast am I?
Well I can turn the light off and be in bed before it goes dark. 🙂 😛
