Robert.Dark is not something that does not have motion, it is something that automatically appears in the absense of light. Example: If light were shining through a window and you put a curtain down then darkness(assuming all light was being blocked) would be an instantaneous occurance. P.S. The Speed of Dark is a near future sci-fi novel written by Elizabeth Moon...I hear it is quite good

That may be true, but there is another theory that is floating around.... (It's kind of lengthy though) For years it has been believed that electric bulbs emitted light. However, recent information from Bell Labs has proven otherwise. Electric bulbs don't emit light, they suck dark. Thus they now call these bulbs dark suckers. The dark sucker theory, according to a Bell Labs spokesperson, proves the existence of dark, that dark has mass heavier than that of light, and that dark is faster than light. The basis of the dark sucker theory is that electric bulbs suck dark. Take for example, the dark suckers in the room where you are. There is less dark right next to them than there is elsewhere. The larger the dark sucker, the greater its capacity to suck dark. Dark suckers in a parking lot have a much greater capacity than the ones in this room. As with all things, dark suckers don't last forever. Once they are full of dark, they can no longer suck. This is proven by the black spot on a full dark sucker. A candle is a primitive dark sucker. lA new candle has a white wick. You will notice that after the first use, the wick turns black, representing all the dark which has been sucked into it. If you hold a pencil next to the wick of an operating candle, the tip will turn black because it got in the path of the dark flowing into the candle. Unfortunately, these primitive dark suckers have a very limited range. There are also portable dark suckers. The bulbs in these can't handle all of the dark by themselves, and must be aided by a dark storage unit. When the dark storage unit is full, it must be either emptied or replaced before the portable dark sucker can operate again. Dark has mass. When dark goes into a dark sucker, friction from this mass generates heat. Thus it is not wise to touch an operating dark sucker. Candles present a special problem, as the dark must travel in the solid wick instead of through glass. This generates a great amount of heat. Thus it can be very dangerous to touch an operating candle. Dark is also heavier than light. If you swim deeper and deeper, you notice it gets slowly darker and darker. When you reach a depth of approximately fifty feet, you are in total darkness. This is because the heavier dark sinks to the bottom of the lake and the lighter light floats to the top. The immense power of dark can be utilized to mans advantage. We can collect the dark that has settled to the bottom of lakes and push it through turbines, which generate electricity and help push it to the ocean where it may be safely stored. Prior to turbines, it was much more difficult to get dark from the rivers and lakes to the ocean. The Indians recognized this problem, and tried to solve it. When on a river in a canoe travelling in the same direction as the flow of the dark, they paddled slowly, so as not to stop the flow of dark, but when they traveled against the flow of dark, they paddled quickly so as to help push the dark along its way. Finally, we must prove that dark is faster than light. If you were to stand in an illuminated room in front of a closed, dark closet, then slowly open the closet door, you would see the light slowly enter the closet, but since the dark is so fast, you would not be able to see the dark leave the closet. Just a little something to think about.

Well, light and dark are exact opposites so I would say that the speed of dark = the speed of light. Or maybe it's negative? I dunno it's a thinker.....

Actually, dark can travel faster than light. Here's how. Imagine you're standing inside a large gymnasium with no ceiling. It's a bright day and as the birds fly over you see their shadows glide over the gymnasium floor and walls. You notice that the shadows on the ground move at the same speed as the birds, but the shadows on the walls have to move more quickly vertically in order to keep up with the birds as they move horizontally. Well, if a bird was traveling at or near the speed of light, as its shadow moved vertically on the wall it would have to travel faster than the speed of light to keep up with the bird. So, if objects can move at or near the speed of light, their shadows on perpendicular surfaces must go beyond light speed to keep up with them. Voila! Dark is faster than light.

"Pass! Ask me another!"...

I'd think it would be the speed of the light going away when you turn off the light or block it or whatever.

speed of dark is 0 zero because you have the speed of light as in from dark to light

Since darkness is an absence of light it moves as fast as the departing light.

Ask a black hole.

Since "dark" is the absence of light, you could say that it is the same as the speed of light. Consider a light bulb in the middle of empty space somewhere, and this light bulb is able to turn off instantaneously. When the light turns off, you can imagine a "shell of light" continuing to move outward from the light bulb. Its inner radius expands at the speed of light, and this radius also defines the boundary of the sphere of "dark", which is expanding at the speed of light. I hope that helps.

I think the speed of dark would be the speed of light. But, deep inside, I know its a little slower.

Are you suggesting amphetamines used by Caucasians are different than speed used by African Americans?!?

Sped of light with a -ve sign.

http://home.netcom.com/~rogermw/darksuck.txt Just google "dark suckers". There's alot about it out there. :)

dark means blindness so nobody finds comfortable to find out the speed of dark but i think it speeds as same as light.

Ask Batman!

Light can travel at 300000000 meters per second. Light is a phsical entity. It is a wave. When you switch on a light, it enters the room at that speed. Darkness is NOT a physical entity. It is just the name we have given to describe the absence of light. It is not a wave, it does not have energy, and it does not have speed. In fact, it's inacurate to talk about "how fast can darkness enter a room", the correct question would be "how fast can light leave the room". same question, just more accurate. So when taking this into account, you could say darkness travel as fast as light (since light leaves a room as quickly as it enters). And so the answer would be 300000000 meters per second. A good question never-the-less!

Well, dark is the absence of light. It is a non-entity and cannot be defined with the parameters of something that does exist, as say, light. If you wanted to argue that in light travels at 3x10^8 m/s and so it would be dark in a specific amount of time because the light has passed... eh, that might work. Truthfully, dark is a nothing and cannot have a speed. It doesn't, technically, even exist.

According to Terry Pratchett, it's the fastest thing there is, because every time light tries to race it somewhere, it finds the dark already there waiting for it.

according to my calculations it is the exact opposite of the speed of light. +5 for the dumb@ss without a sense of humor

The speed at which the republican spin doctors get their version of a story out?
