may some one tell me  light speed is?
349230
in english it's 186,000 miles per second

I recall it was something like, \n\nWarp 1 - Speed of light\nWarp 2 - 12x speed of light\nand so on. \n\nUpdate: Did a little more research, and found this:\n\nThis chart compares TOS-era Warp speeds with the speed of light:\n\nWarp ......  Velocity   \n1 ...............1  Speed of Light  \n2 ...............8   \n3 ..............27   \n4 ..............64   \n5 .............125   \n6 .............216  Maximum stable speed of NCC-1701  \n7 .............343   \n8 .............512  Emergency speed of NCC-1701  \n9 .............729   \n10 ...........1000   \n11 ...........1331   \n12 ...........1728   \n13 ...........2197   \n14.1 .........2803  Episode: "That Which Survives" [TOS]  \n \n\nAnd, here's something fun... it's a warp factor calculator to figure out how long it will take you to get to your destination at different warp speeds:\n\nhttp://home.att.net/~srschmitt/script_warpcalc.html

lightspeed is about 186,000 miles per second and the sun is about 93,000,000 miles away.  Divide and you get 500 seconds, which is 8 minutes 20 seconds.

the speed of light, c, is measured to be the speed in vacuum......\nall other mediums (or media?) have greater index of refraction n, (for all other meduims n>1), thus, slower speed of light...\n(for vacuum n=1, for air n=1.003, for water n=1.33 )\nthere can not be a medium where n<1....\n\nif, however, there is a discovered medium such that n of the medium is less than the n of vacuum, the speed of light known to be c is not anymore valid...there will be a new speed of light measured....

Energy = mass x speed of light squared

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

A light year (or light-year), is defined as the distance that a photon would travel, in free space and infinitely distant from any gravitational or magnetic fields, in one Julian year (365.25 days of 86,400 seconds each). Since the speed of light in a vacuum is exactly 299,792,458 m/s by the definition of metre, one light year is exactly equal to 9,460,730,472,580,800 m, or about 5.879 × 10^12 (nearly six trillion) miles.

The accurate speed of light is 299,792,458 m/s.

Actually there is no speed of dark.\nBut according to me it should be the same as the speed of light because as soon as the light goes the dark appears.So it must be as the speed of light i.e. 3* 10^8 meters/seconds

the opposite of the speed of light :)

The speed of light in a vacuum is 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; sometimes roughly 300,000 km per second). This value is denoted by the letter c, reputedly from the Latin celeritas, "speed", and also known as Einstein's constant. Note that this speed is a definition, not a measurement, in that the fundamental SI unit of distance, the metre, is defined in terms of the speed of light: one metre is the distance light travels in a vacuum in 1/299,792,458 of a second. The speed of light through a transparent medium (that is, not in vacuum) is less than c; the ratio of c to this speed is called the refractive index of the medium.

wavelength = speed of light/frequency\n\nwavelength = (299792458[m/s] / 100000000[1/s])\nwavelength = 2.99792458m

The speed of light is a CONSTANT and has the symbol c in Science and is measured in meters per second.\n\nc (the speed of light) is equal to 3 times 10 to the power 9.\n\nNow 3x10*9 meters per second equals 3000000000 meters per second. (3 then nine zeroes!).\n\nc is important in physics because nothing can go faster than  c. \n\nNothing can go faster than the speed of light and as Einstein showed with the Theory of Relativity (a very important theory in physics) when an object (mass if you will) approaches c it gets bigger and bigger!! \n\nIf it gets to c then its mass will become infinite - this is impossible! An object with infinite mass! Hence it is impossible to reach the speed of light. \n\nHope this helps.

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.

The speed of light in a vacuum is exactly 299,792,458 metres per second or 1,079,252,848.8  kilometres per hour. Converted to approximate imperial units, it is 186,282.397 miles per second, or 670,616,629.384 miles per hour.

The speed of light is only defined as a positive number.\n\nThere is no inverse of light speed - no "negative" light speed.\n\nThe speed of "dark" is undefined, since anything times nothing is undefined.  \n\nAll you can do is state how fast light moves out of a location once its source is discontinued.\n\n\nBy the way, saying that "everything has an opposite" is a false statement.\n\n\nHowever, I can see a case for considering that there may actually be a phenomenon of dark spreading at alarming speed, namely the Republican Party.

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
