![]() ![]() ![]() ![]() The many-particle problem, which would decide the value of the theory, has not yet been treated. relativity, wide-ranging physical theories formed by the German-born physicist Albert Einstein. In this case, because of the absence of singularities, the field equations determine both the field and the motion of the particles. The many-particle system is expected to be represented by a regular solution of the field equations corresponding to a space of two identical sheets joined by many bridges. The most natural elementary charged particle is found to be one of zero mass. The combined system of gravitational and electromagnetic equations are treated similarly and lead to a similar interpretation. In the third in particular he used general relativity to explain the precession of the perihelion of Mercury. One is able to understand why no neutral particles of negative mass are to be found. In his four papers, published in November 1915, Einstein laid the foundation of the theory. These solutions involve the mathematical representation of physical space by a space of two identical sheets, a particle being represented by a "bridge" connecting these sheets. By the consideration of a simple example they are led to modify slightly the gravitational equations which then admit regular solutions for the static spherically symmetric case. The writers investigate the possibility of an atomistic theory of matter and electricity which, while excluding singularities of the field, makes use of no other variables than the g μ ν of the general relativity theory and the ϕ μ of the Maxwell theory. ![]()
