A question from Twitter ...

A significant lack of electromagnetic radiation in the visible spectrum.

A different question should be asked first: what is light?

A ray of light DOES NOT split into any component colours:

Tides and radio waves:

Light cannot be anything else but a longitudinal disturbance in the ether, involving alternate compressions and rarefactions. In other words, light can be nothing else than a sound wave in the ether.

Nikola Tesla


Darkness simply means that the aether and ether have not been activated.


Cymatics, how to activate the latent aether by sound:

Perhaps the author of the question was referring to outer space...there is no such thing as outer space.

This is what our universe looks like:








Where is our universe located?

What is the scale of our universe?

Where is the only place a universe could have been created?

What does it mean for space to be dark? Broadly generalising, the light we see is that which was reflected or emitted from other objects at such an angle that it reaches our eyes. Outer space itself isn't any darker than your room. It's just that the stuff up there covers a relatively small fraction of a human's angle of view.

Long story short, my answer is: space isn't dark.

because an atmoshere is needed to produce light.
