if you walk into a pitch black room and flick the lightswitch on it goes bright quickly ...., but the dark was there first surely ?? does this mean that speed of dark is faster than the speed of light ????

You're confusing different concepts and the same word used as an adjective here, but with different meanings. "Dark", in your garage example, is just the absence of light. Dark doesn't move - light leaves, and the absence of light remains. It's like shutting off the water in your shower. You don't suddenly get hit with a bunch of non-water. The water stops flowing, is all. "Dark matter" is simply matter that we can't detect. Scientists CAN measure the speed of objects as they move through space, and can estimate their mass. They also know the laws of motion that all mass must follow, be they something the size of a bagel, or something the size of the Andromeda galaxy. The stars and galaxies that we can see don't follow the rules correctly - the stuff that we can see doesn't have enough mass to move the way it does. They move as if there was much more mass involved somehow. So scientists and physicists decided that there must be more mass out there, and they've given the name "dark matter" to this mass.

In reality, there is no such thing as dark. Dark is simply the absence of light. Just like quiet is the absence of sound, cold is the absence of heat, etc.

The reason you perceive light getting brighter / changing intensity once you flip the switch is because your eyes are adjusting how much light they're letting in after the brightness in the room changed.

The reason a room doesn't seem instantly dark when the lights go out is that your eyes are still having residual effects from the recent stimulation of the light that was previously there. (Like removing a pan from a burner on a stove doesn't instantly cool it to room temperature) It's not because that's how

If there were physically such a thing as darkness (negative light), then its presence would actually cancel out light - leaving behind less of whichever was present in greater quantity (light or dark).

Sending Light Matter faster then the speed of light is not Hard.
By creating a Method to send Communications Faster then the speed of light itself...Piece of Cake !
Answer was figured out by me years ago...Multiple laser pulse Communications, And it's fastest way ever...

Not really. If you walk into a room and a very very fat man and a very fat man is in there does that mean he is a faster runner than you? Just because something is there first does not mean it travels faster. If I set off now I could walk a mile in 15 mins, a good runner can run a mile in 4 mins but if I set off 12 mins before the runner I get there first but my speed is a lot slower.

According to Einsteins Theory of relativity, there is no way to go faster than the speed of light. But some other branches of mathematics state that Tachyons can go faster that light, if only because the mathematical equations need them to exist for the theory to be true.
Darkness is only the absence of light. You are not faster than me just because I am not there.

no the fastest thing is not just light, you are refering to "the speed of light in a vacum" it is the same as the speed of any form of electromagnetic radation in a vacum(anything in the electromagnetic spectrum) , ie radio waves, microwaves, infa red rays, normal light, ultra violet, x-rays, gamma rays and cosmic rays (in that order from largest wave-lengh to shortest) is speed is 299,792,458m/s normally it is writen in standard form 2.99792458 x 10 to the power of 8 just a little 8 to the upper right of the 10. but no dark is not faster than light, dark is an absence of light, it carries no energy, and has no "photons" it is just what you see when there is no light, a visual perseption, but there in to detect dark from the absence of light is the time it takes for your eyes to rely that to your brain.

no. According to scientific theory, dark is the absense of light. Light is composed of weird particles called photons. If your eye doesn't detect any photons, it sees "dark", which is just your brain's way of telling you that you don't see photons. Light comes in different frequencies and wavelengths, which is what causes variation in color. A pure mixture of all the different frequencies produces white light (note: it doesn't work this way for things like paint, where a mixture of paints gives you a brown-black color).
