What is the speed of Darkness?

Asked by SunitaMishra (15points) 1 month ago

As there is speed of light so there should be speed of darkness, just curious to know if there is any theory around that.

Darkness isn’t a thing as such it’s merely the absence of light therefore it can’t have a speed.

I suppose you could say that it is the same as the speed of light. If you have a light source and turn it off, the end of the light and beginning of the darkness travel at the speed of light.

No, since darkness is merely the lack of light.

There has got to be a rule that this question appears every few years on QA sites.

Yeah, dark isn’t something. Dark is something leaving.
