Answer 1

There is no such thing as "dark light", there is only light or the absence of light. The dark sky is simply the absence of light. Dark isn't a real thing, it is just a lack of a real thing, the real thing being light.

Note that the sky is not totally dark, juts too dark for your eyes to see. There is some dim light everywhere, from distant stars or the cosmic microwave background or whatever, but it is all "light".

Answer 2

That darkness is just the mere emptiness of space. Some of it's light that has not got to us yet while most of the darkness is space. People say it's dark matter and energy but the substance is the gravitational gap fillings.
We live in a 3d universe that is infinite with over that infinite space is nothing apart from these galaxy clusters. There is other dimensions to explore.
Physics or Greek term φυσικός give the 3rd dimension in the gap called the universe.

Answer 3

Indeed, it is just (almost) empty space, with nothing to reflect (to our eyes) the light falling on it from the stars you see. But, read about Olbers Paradox..Olber stated that if there were an infinite number of galaxies, then the more numerous ones further away would add up to the same as the less numerous nearby ones, and we should see dazzling light in all directions. It was a big hairy deal explaining that one (intergalactic dust and the expansion of the universe is part of the explanation).

Answer 4

What you're seeing is a little bit of the sun's light reflected through the atmosphere to the dark side of this planet. Also, light from cities reflects back down to the surface.

Answer 5

A vast emptiness where a light from a star or any heavenly bodies were not able to disturb.

Answer 6

It is not a dark light, it is that part of the universe which we can't see because the light has not reached us yet.

Answer 7

dude your whole yahoo 360 journal thing is spam.

it is what it is, space, and it looks the way it is only to us. if we "saw" in any other part of the spectrum the sky would look vastly different.

peace, spammer.

Answer 8

THE LACK OF MOST LIGHT. ONLY A LITTLE COMES THROUGH FROM MOON AND STARS.

Answer 9

Ultra-violet, this "dark light", is only visible by x-ray, it has been done, check-out NASA, site...

Answer 10

Nothing
