General relativity, also known as the general theory of relativity and Einstein's theory of gravity, is the geometric See more

Henri Poincaré's 1905 theory of the dynamics of the electron was a relativistic theory which he applied to all forces, including gravity. While others thought that gravity was instantaneous or of electromag… See more

General relativity can be understood by examining its similarities with and departures from classical physics. The first step is the realization that classical mechanics and Newton's law of gravity admit a ge… See more

The derivation outlined in the previous section contains all the information needed to define general relativity, describe its key properties, and address a question of crucial importance in physics, namely how the theory … See more

General relativity has a number of physical consequences. Some follow directly from the theory's axioms, whereas others have become clear only in the course of many years of research that followed Einstein's initial public… See more

Examples of physicists who support neo-Lorentzian explanations of general relativity are Franco Selleri and Antony Valentini. See more
