Just tried an experiment with a bag of dark and when I opened it it instantly vanished so it must be the same as the speed of light, but beware because dark can hide but light cant

There is no theoretical limit to the speed of dark. Imagine a screen placed several metres from a light source. If the light source has a very small width but the light is dispersed on the screen and a bullet is fired across the source at a speed approaching the speed of light the shadow on the screen moves much faster than the speed of light. This does not violate the special theory of relativity, as dark is the absence of light.

When we speak about the speed of light we mean the speed of an electromagnetic wave of a particular wavelength. Dark is not the opposite of this and so has no speed anymore than say cold, hard, yellow or scent has.

It is the same as the speed of light. If a light source is terminated, the illumination of a distant object ends only when the last light emitted by the source reaches it. That's the light that was emitted at the moment when the source was terminated, so it reaches the illuminated point after the amount of time that it takes for light to reach that point. The point subsequently experiences darkness, and the effect reaches the point in the same amount of time it normally takes for light from the source to reach that point.

The Speed of Dark is a book by Elizabeth Moon.

"In The Speed of Dark, Elizabeth Moon has created a powerful, complex, and believable portrayal of a man who varies radically from what is defined as "normal." The author insightfully explores the nature of "normality," identity, choice, responsibility, free will, illness and health, and good and evil. The Speed of Dark is a powerful, moving, illuminating novel in the tradition of Flowers for Algernon, Forrest Gump, and Rain Man . --Cynthia Ward --This text refers to an out of print or unavailable edition of this title."

The same as the speed of light.
Darkness is the absence of light.
If there is a place that has light, then it can move away at the speed of light, creating darkness.

Darkness does not exist, therefore it does not have a speed. Darkness is not "something". It is the absence of something, namely light. Therefore it has no physical characteristics of its own. The same can be said of silence (absence of sound), and cold (absence of heat). Heat, sound, and light can be measured. They can be reflected, refracted, filtered, etc., because they are real entities. You cannot reflect an absence. You cannot measure an absence. An absence has no speed or intensity or any measurable characteristic.

I suppose it's the reverse of the speed of light, as light speeds away from it or it could just be how fast you can jump off the settee and flick the switch.
