What if the dark shines in the light and not light shines in the dark? What if???

dark is the absence of light...

Its refering to sunlight. Only sunlight goes low or dim (We were afraid that the light was too low)

Assuming that each bulb is turned on, the answer would be no.  While bulb A may block the light cast by bulb B - the blocking of light is how shadows are formed - bulb A would cast its on rays, thereby illuminating the spot on the wall where the shadow would have otherwise been.

the speed of light of course.  dark is the absence of light, so theoretically, the speed of darkness moving in is the same as the speed of light moving out.

If you mean how are shadows formed, the answer is simple.  A solid object blocks light.  Since the light can't go through it, then the area all around it has light, but the area right behind it is dark.  \n\nSince light bounces around, it's not completely black inside the shadow.  Some light will still bounce in there and light it up a little, but it won't be as much light as the area around it.  Less light = shadow.

Darkness has no speed. However if you could put a speed to darkness it would be amazing. If you could actually produce the absence of light, you would have created pure genious. As of right now, Darkness doesn't have a speed because it is nothing. That is like saying how much am i worth, if you don't have money. Technically you're worth $0 but am I trying to say that you are worth the absence of money. You don't have money so your worth nothing. Darkness isn't something that has a speed because it is the absence of light. I guess a better analogy would be: The absence of money has no worth.

Dark does not push light away, the light is what is moving. Using your example of "over the horizon", the sun (which produces light) moves to the other side of the earth (where we can't see it) then we see dark. But dark does not move, it is just the term we have come up with for what it looks like when there is no light present.

use a blacK light and see what happens

If you shine a flashlight in a dark room, the beam of light must hit an object in order for you to see it. If there is nothing to obstruct the light, then you will still see a dark room despited the flashlight. The same is with the sun, the planets are visible because they obstruct the light and reflect it back to our eyes. Everything else is black because there is nothing there.

Considering that weight is really mass, and mass can be converted to energy, -and darkness, by this definition is void of either mass or energy, then no darkness does not have weight.\n\nBut if in the middle of night you get out of bed, and it's dark and you hit your foot on a chair, then yes, darkness does (have) (include) weight.

The light will be on/off

There isn't a speed of dark...Darkness occurs only when there is an absence of light. Therefore the speed of dark will reflect the speed of light dissipation.

A lamp. I feel "enlightened" by much that I have learned. Perhaps if the lamp is turned on (not that way ....for shame!) it could provide illumination to those who can not see in the darkness. Yeah...I wanna be a lamp. :)

dark doesn't exist, what we measure is the absence of light so there is only the speed of light not dark

Tricky....\nI assume that it will be impossible to see the light inside the ball. When you "see" things is because the light bounces on the surface of objects into your eyes... As the light in this hypothetical ball cannot get out of the ball and towards your eyes, you'll see just a dark shiny ball... (i guess)

Sorry but darkness is not a measurable thing. the absence of light however is! The absolute absence of light leaves the condition referred to as darkness. likewise cold does not exist only the absence of heat. thermal dissipation is the term I believe so I guess we could call darkness, photonic dissipation? wink wink nudge nudge.

Does Darkness really exist?
