The speed of darkness

De nihilo nigra

Darkness appears out of nothing and dissappears into something.
It expands with the speed of 299.792.458 meter each second
(equals 1000 million km pr hour).

Darkness grows with the square of distance.

Darkness has neither form nor shape,
but if you would like a particle-shape,
I'll suggest the name Noxon...
