This is the correct answer.
+1 or -1.
Agreed. Speed of dark is the speed at which you run out of light, which is the speed of light.

Of course, this is ignoring the question of "In what medium". Free-space speed of light is different from speed in glass, or water, or other materials. (Air doesn't affect it much.) I *seem* to remember that this is related to the dielectric constant of the material, but don't hold me to that one.
Right.  The speed of dark is the same speed as the speed of light, for whatever the given medium might be. 

Similarly, the speed of silence is the same speed as the speed of sound, again, in the specified medium through which the sound, or absence of sound, is traveling.
And the speed of cold is the same as the speed of heat.
Permittivity and permeability: Its one of those magic moments in EE school when you spend two hours deriving it all from first principles, and the answer drops out, just before the end of the exam.
c = 1/√εμ
Thanks. It's been too long; all of that is thoroughly swapped out. (I suspect I could recover it fairly quickly if I needed to by digging into the books, but... well, there are reasons my career drifted back to software.)

It is an established fact that dark moves very slightly faster than light - no matter where you shine your light, the darkness was their first.

I thought that darkness was slightly slower than light, cause it only gets there AFTER the light leaves.

It's sneaky - it gets there first, hides while the light is about, then comes out again as soon as the light is gone.

Are you looking for the most clever misinformation or an accurate answer?

 I pretty sure light moves, but darkness doesn't, just like sound moves, and silence doesn't.

Darkness is the absence of light; it is always present everywhere, just that light will take its place...
...meaning, it has no speed.
my gut says correct. or zero, whichever comes first
Its 42. pretty much un-debatable.

Below, you'll see the two conventional wisdom answers, with a third being darkness (d) being d = SQRT (e/m) +1.  However, what the government won't tell you, the real answer depends on the ninja's motivation, and is therefore variable.
