Hmmmmm

Dark is just an absence of light, it doesn’t move lol

Cold is the absence of heat, but cold is still heat........

Light, heat/cold, sound, matter are conversions and forms of energy, darkness isn’t a form but a absence of traverse light.

Not saying there isn’t other forms of energy in darkness or motion but a lack of light that relates to the question.

* the traverse of lights perturbation

Heat is different than light.

But, they both move........

Cold is a temperature. There is no such thing as cold, only heat. Cold is a relative term, but there is only hot and less hot.

The speed of dark is the same as the speed of light

Dark is just the absence of light. There is no speed of dark. There is only light and less light

I know but dark being the lack of light means it is the same speed as light

Absence doesn’t have a speed

You can’t give a speed to nothing. Dark is the absence of light without a speed. Light has a speed because it is a physical thing. The absence of speed is what dark is

Well think of this if there is a horse running 30mph how fast would it be for there not to be a horse? 30mph

-_- No, that’s not how that works

this question makes my brain hurt

Nothing because light has stopped traveling so it’s already dark.

Dark is the absence of light.

dark is the abcense of light so I guess no speed

Like @ChthonicGnosis said, light is just the absence of light so relatively speaking, it's not of physical properties, therefore it can't be measured. So, before getting theoretical about stuff, darkness is just light's shadow, it travels in unison, always filling up one, or the other.

So light matter moves...dark matter doesn't??? and yes, I can add matter here, pyshical properties are applied to light alone......
