Speed of light is invariant
WebInvariance of the speed of light The Michelson-Morley experiment, among other experiments, showed that the speed of light in vacuum is a universal constant, as … WebFeb 3, 2024 · In non-inertial frames the coordinate speed of light is arbitrary and can even be much greater than c. In GR there are no global inertial frames, only local ones. What is invariant is that light always travels on null geodesics. In a local inertial frame null geodesics are the paths traveling at c.
