Sarcastic remark goes here
Dark is the absence of light. So it travels at the same speed.I know what the speed of light is. I just wonder what moving at the speed of dark is?
It takes 8 minutes for light to reach Earth from the sun. An event like a solar flare happens 8 minutes before we can see it happen here. So if the sun were to suddenly turn off and go dark, we would continue to have light for 8 minutes. Specifically, it's the absence of light that would take 8 minutes to arrive.
