Even this might not be correct, and its about at this point that my head starts to implode. The theories about the exploding relative universe are about us also being in motion and expanding at a rate similar to C, so where does that leave us....buggered if i know....
oh gosh......even the serious comments are weird in this thread.
For the record, the properties of light are not fully understood , and cannot be explained by any single theory. Since darkness is essentially the absence of light, its going to follow that our understanding of the properties of darkness are just as incomplete as they are about the properties of light.
For the record light displays some of the qualities of a particle, but by definition has no mass. This suggests, along with other properties of light that it has some properties of a wave.
Light cannot have mass because it cannot and does not obey the accepted laws of physics. If it has mass, einstein and others have proven that it would require more energy than is available to move even a tiny particle of mass. Moreover, as mass starts to approach the speed of light, "C" , its mass increases, until when it reaches the speed of light it has an infinite mass. Moreover, as mass approaches the speed of light, the passage of time for that mass would slow down, until by the time that "C" was reached, time for that object would actually stop. it has been theorised that if the object was somehow able to exceed the speed of light it might actually start to move backwards.
Light is not slowed or stopped relative to outside observation, but we have never been abale to travel at c so cannot know what is happening to time relative to the beam of light itself. We cannot tell if two beams of light shooting parrallel to each other, on parrallel course with each other, would see themselves or each other as two ships sailing parrallel to each other might be able to see each other.

Well, here's the real question...
Is the light on in the 'fridge before the door opens, or just as it opens?
And, if you open the 'fridge at night, with the kitchen lights off, does any dark get into the 'fridge before the door closes?
I think some people thought he said that but they live in N KoreaWonder what would have happened if the 'Boss Man' had said 'and let there be Dark' ?
Interesting subject...
But dark doesn't travel (or move in a perceptable fashion) since it's always present.
When you turn off the light in the room, the darkness seems to fill the room as the lamp shuts off, but in actuality the light diminishes from the darkness.
An analogy would be an empty glass. It is just a void until someone fills it with liquid. So you don't ask "how fast the void travels", you ask how fast the liquid fills the glass. The same could be said for pouring out the liquid. You don't gauge the speed the void of the glass increses, you measure how fast the liquid flows from the glass...
...and when it's been dark for a long time, it gets really really pitch-black dark???
