(physics) The speed of electromagnetic radiation, which in a perfect vacuum is equivalent to 299,792,458 metres per second.
Due to its finite speed, sunlight takes 8 minutes and 10 to 27 seconds to reach Earth, depending on the time of year.
(physics) The speed of electromagnetic radiation, which in a perfect vacuum is equivalent to 299,792,458 metres per second.
The Lorentz factor γ as a function of velocity. It starts at 1 and approaches infinity as v approaches c.
(physics) The speed of electromagnetic radiation, which in a perfect vacuum is equivalent to 299,792,458 metres per second.
Event A precedes B in the red frame, is simultaneous with B in the green frame, and follows B in the blue frame.
