If we need light 2 c things, how is it then that we can c the dark? If light is present,it cant be dark..rite?

Question

It can therefore be concluded that darkness is imaginary/not real...

Answer 1

We can't "see" dark. What we see as darkness is simply very low levels of light.
A shadow is dark only by comparison to the light around (like the shadow you make in sunlight, you see the shadow because there is still light even in the shadow).
We would see nothing in absolute darkness (say in a completely sealed room with no windows or any light source).

Answer 2

When you go into the dark, your pupils open wide, and you have special dim light receptors in your retina that kick in. About 100 times as much light information is received by your brain as when you are out in bright sunlight.

That means you can see in very little light, once your eyes adjust.

However, in absence of light, you won't see a thing.

Yes, the closet idea is good. wait til night. Keep the drapes closed, switch off all the lights, and then go into a closet.

The only thing you will see is that your conclusions are wrong. You cannot see in complete darkness.

Answer 3

No darkness is nothing but light not reflected off things, whatever we see is light bouncing off matter, thus a photo receptor like our eye will get stimulation from light coming out the visible spectrum, if matter doesn't reflect light there is darkness, so in real everything is in darkness unless light comes out of the matter or bounces off it.So to answer you question darkness is not hypothetical and can be measured until -infinity.

Answer 4

I think u guys forgot to mention the extremes at either end such as ultraviolet and infra-red. "Dark" refers to the range that our human eye percepts. However "night-vision" goggles (the goggles that marines put on at night that makes everything a shade of green) recieves infrared through special receptors on the lenses. So in fact, "Dark" to the human eye mean lack of colour, but "Dark" in astronomical terms means lack of radiation. (spanning outside the perception of the human eye. Light is a form of radiation from particle theory and wave theory, although I dun really wanna get into that cuz I still don't know whattheory they are now using for light...is it a wave or is it particles? or both? hahah).

Yeah so long answer short, "Dark" to the human eye means lack of colour, "Dark" in Astoronomy means lack of radiation.

ta!

Answer 5

What you think of as dark has actually got plenty of light from a variety of sources. "Dark" is a human definition that means low light, not a real physical state.

Answer 6

As dark as it gets your eye is very sensitive, so there is light present. Absolute darkness is easily attainable artificially and in nature in the nights when there is no moon and no light pollution it can get pitch black. But you are right. For instance there is no color black. The same goes for white. White is our interpretation of all the different 'colors' blended together. Black is the absence of color. So even the blackest black is reflecting light.

Answer 7

we see in the dark because there is still a small amount of light.

complete darkness in nature is rare.

stars planet moon ...ect

try going into a closet and closeing the door and block all light seeping around the edges of the door.

then see if you can see in the dark

Answer 8

dark is not imaginary. when it is dark, my optical sensor tells me so . therefore it is not imaginary. life at the bottom of the ocean, where it is so dark, these creatures produce their own light , through phosphorescence.

Answer 9

your right. darkness is a term to describe LACK OF LIGHT.
if you can see in the dark, there's still light. true darkness is having no light at all.
