Does dark travel at the same speed that it takes for light to disappear or move on? Or does it have its own metrics entirely?
In: Physics
Light is a wave (enough of the time for this to work). So imagine you have a long piece of rope attached to the wall near the floor and pulled out perpendicular. You can give that rope a snap and send a pulse down it. If The speed of the pulse represents the the speed of light, then what you asking is what speed does the rope return to flat. So yeah, I think as far as we can talk about the speed of the returning absence of something, in this case light, the speed of dark is the speed of light.
