Speed of light = 3x10^8 m/s
It is derived from the equation:
c = 1/sqrt(u_0*e_0) where:
u_0 = permeability of free space
e_0 = permittivity of free space
-----------
Hope this helps

Light travels at a speed of 186,000 miles..amazing to think that light takes 8.6 minutes from earth to reach the sun, so our view of the universe is always out of date....

299,792.458 km/s is the speed of light in vacuum. However, according to Einstein's theory of General Relativity, the speed of light appears to vary with the intensity of the gravitational field.
