1. 1. Constant speed of light principle: the speed of light in a vacuum is the same for any observer. In special relativity, the principle of constant speed of light means that no matter what inertial frame (inertial reference frame) is observed, the propagation speed of light in vacuum is a constant and does not change with the relative motion of the light source and the observer's reference frame. This value is 299792458 M / s. space almost precisely matched the speed of light repeatedly measured by experiments - a speed that didn't change no matter what. An observer could be running toward the light or. Link: https://bit.ly/3u0EyyO
