In 1915, A. Einstein described gravity in the theory of General Relativity on the basis of differential geometry as a curvature of a 4-dimensional space-time. From 1920 on to the time of his death in 1957, he tried to unify …

Gravitodynamics is based on an 1893 article of O. Heaviside or, respectively, on a simplication of A. Einstein’s General Relativity. It represends a set of equations for gravity and gravitymagnetism quite similar to the Maxwell-equations for electricity and magnetism. As …

The Paraconical Pendulum was used by its inventor M. Allais to search for gravitational anomalies during the solar eclipses of 1954 and 1959. Because he claimed to have found an unexpected change in rotation sense and velocity of the pendulum …
