Is 'C' Faster Than the Speed of Light?

[aby001234]

Is it same as 'c'?
or is it greater (though it may be very small difference) than the normal
speed of light?

 

[Pengwuino]

The speed of light is 'c' no matter how fast an observer is going. That's one of the guiding principals behind special relativity.

Passengers aboard airplane measure it as 300,000km/s (c).
Onlookers on Earth on measure it as 300,000km/s (c).
Aliens passing by overhead at .9c measure it as 300,000km/s (c).

the speed of light comes from the solution to wave equation for E and B fields.
And then number is constant.
