Abstract

Constancy of the speed of light in time-spatial area with the same gravitational potential (or in time-spatial area with equal level of contraction/expansion of the space-time) is demonstrated. All of the experiments (“One-way”, “Two-way” and “Multiple-way” measurements) are made in time-spatial area with the same gravitational potential (or in time-spatial area with equal level of contraction/expansion of the space-time) – this is the Earth’s surface. Explanation that there is no change in the value of the speed of light in all of the above mentioned experiments is given.

The speed of light (or of the electromagnetic radiation) is changing only when the light passes through time-spatial areas with different gravitational potentials (or in time-spatial areas with different levels of contraction/expansion of the space-time). The Pioneer 10 and 11 Acceleration Anomaly is actually a proving experiment of this reality.
