Same as the speed of light. Darkness is only the absence of light, so when light leaves a specific "space" (at the speed of light) then the time it takes to be dark there will be equal to the time it takes the light to leave.

In discussing hypotheses about dark matter, scientists have developed the terms "cold" dark matter, "warm" dark matter, and "hot" dark matter; with the "hot" hypotheses viewing dark matter as moving faster than it would if it were "cold."
