ELI5, does DARK have a speed at which it travels, in the same way that LIGHT does?

Question

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?

Answer 1

“dark” is the absence of light. so it moves at lightspeed if you want to give it a speed, but in general it doesnt make much sense to define the speed of “nothing”.
