The Geometric Meaning of Time and the Limiting Speed of Signal Propagation

摘要

The geometric representation of the space of events is proposed, which is radically different from pseudo-Euclidian Minkowski space. In the framework of the new model, the space of events is reflected onto a four-dimensional Euclidian space in which time multiplied by the speed of light can be considered as a length of geodesic line. The existence of the limiting speed of motions appears to be the consequence of the proposed geometric interpretation of time. The possibility for the new interpretation of time is discussed in order to consider distortions of GPS signals when they pass through the Earth's ionosphere.
