The speed of dark is a fascinating sci-fi book about an autistic man.  Very good.

The speed of sound isn't even close to the speed of light. The speed of sound in air is usually given as 343 meters per second at sea level in air and the speed of light is approximately 3 X 10^8 meters per second (300,000,000 m/s)in a vaccuum.

This can be proven with a simple experiment.  Light travels at 186,000 mps, if you go to a desk or anything with a drawer that can be pulled out, while the drawer is closed it can be fairly safe to say that it's dark in the drawer.  When you open the drawer you will find that the dark excaped before the light got in.  So, you can safely say that darkness travels faster than the speed of light.

The speed of light in a vaccum (any space with no matter to interfere) is 299,792,458 metres per second.  Light travels slower through fluids like our atmosphere, and water, and through translucent or transparent matter like lenses.

the speed of light is c=3*10 at the 8-th power  m/s\ndark means 0 light

In a vacuum, the speed of light is 299,792,458meters per second and sound is 344meters per second at sea level and 70deg Fahrenheit.\n\nHowever, these speeds are dependent on various outside factors--namely the material they are passing through.

Darkness is the absence of light, although earlier in history it was sometimes viewed as a substance in its own right. \nLooking at this definition, if we were to define what is "speed of light", it would be the speed at which light is leaving a point. And the speed at which light can travel through any point is the constant 'c' used to define the speed of light. \n\nThe speed of light in a vacuum is defined to be exactly 299,792,458 metres per second (or 1,079,252,848.8 km/h, which is approximately 186,282.397 miles per second, or 670,616,629.4 miles per hour).\n\nSpeed of Dark is a Book\nHere's the detail's\nThe Speed of Dark\nElizabeth Moon\nBallantine Books, $23.95, 340 pages, ISBN:03454475570

The speed of light is Warp 1\n\n2xspeed of ;ight is warp 2\n\nand so on and so forth.

There is no speed of darkness.  Darkness is simply an absence of light.

TNG Tech Manual lists it at 656 times the speed of light. This would also be the same for DS9 and Voyager, as these occur in approximately the same time frame. There is some as-yet-indeterminate algorithim to determine the difference in speeds; some say it's logarithmic, but I haven't seen it.\n\nTOS was much easier. According to the orig. ST tech manual, warp speed = (factor)-cubed * speed of light. Warp 1 = 1c (1^3), Warp 2 = 8c (2^3), Warp 3 = 27c (3^3), etc...

To be precise, what we usually call the "speed of light" is really the speed of light in a vacuum (the absence of matter). In reality, the speed of light depends on the material that light moves through. Thus, for example, light moves slower in glass than in air, and in both cases the speed is less than in a vacuum. However, the density of matter between the stars is sufficiently low that the actual speed of light through most of interstellar space is essentially the speed it would have through a vacuum, so we don't make much error by ignoring the difference.\n\nTo make it easier for you to convert, here is the speed in alternative units :\n\n(1) 983,571,056.4304461 foot/second\n(2) 11,802,852,677.165352 inch/second\n(3) 1,079,252,848.8 kilometer/hour\n(4) 299,792.458 kilometer/second\n(5) 582,749,918.3585312 knot\n(6) 880,991.0899527 mach\n(7) 670,616,629.3843952 mile/hour (mph)

No there is no 'summation' of speeds involved with light.  Light is Electro-Magnetic Energy, although light travels as particles as well as waves.  In this Universe the speed of light is a constant, roughly 186,000 miles-per-second, or 300,000 km/sec or 300 Mega-Metres / sec.  Unless some POWERFUL external force acts upon light, it cannot change speed.  This entails the gravity of black-holes and such. (Not even light can escape from them.)\n\nA vehicle might weigh somewhere in the neighbor-hood of 3,300 lbs. (Approximately 1,500 Kg, for those of you who have not learned to count properly, just yet ...)\nCheck out da' math ...\n\n60mph = 100 kmph = 27.77r mps. \n(1,500 Kg x 27.77r mps) / 9.81 mps = ~ 4,246 N\n\nI doubt, very seriously, that a little over 4,000 Newtons is enough force to even put a dent in the factor of light-speed.  For more info, look-up Einstein's Theory of Realtivity' (Although I believe 90% of it to be short-sighted ancient crap ...)  This subject is covered in it ...\n(umm covered in Einstein's Theory, not copvered in crap .. which err .. is the same thing at times ...

the opposite of the speed of light :)

I'm pretty sure that the red light would go faster than the blue.\n\nThe speed of light is NOT constant.  It is only constant in a vacuum.  In other media, the speed is retarded.  The refractive index is a measure of the degree to which light is slowed when it enters a non-vacuum medium.  The more light is refracted, the more it is being slowed by the medium.  Since red light is refracted the least, I think that's indicative of red light being least slowed by the medium transition.

Scientists have defined the speed of light in a vacuum to be exactly 299,792,458 meters per second (about 186,000 miles per second).\n\nThis definition is possible because since 1983, scientists have known the distance light travels in one second more accurately than the definition of the standard meter. Therefore, in 1983, scientists defined the meter as 1/299,792,458, the distance light travels through a vacuum in one second. This precise measurement is the latest step in a long history of measurement, beginning in the early 1600s with an unsuccessful attempt by Italian scientist Galileo to measure the speed of lantern light from one hilltop to another.\nMicrosoft ® Encarta ® 2006. © 1993-2005 Microsoft
