Abstract: | Using the natural, real units (proper time and proper length) for the definition of the spatial velocity, it is shown that the velocity of light during its propagation through gravitational fields is constant and exactly equal to its value in vacuum. Therefore, according to General Relativity, it is not correct to speak about a variable velocity of light in gravitational fields. |
