Karl Schwarzschild           After 10 years the publication of special relativity theory (SRT), Albert Einstein (1879-1955) published the general relativity theory (GRT) in November 1915, a new gravity theory (the most successful theory at that time was the Newton's theory of Universal Gravitation). Einstein himself thought that the field equations couldn't be solved  precisely. Einstein Field Equations     On that occasion the  World War I  happened and a German physicist and astronomer who was serving the German army provided the first exact solution to the Einstein fields equations of GRT in the same year. His name? Karl Schwarzschild.  T he solution formulated by Schwarzschild describes a spherical non-rotating mass, static, non-charged electrically, it's in fact a vacum solution and is usua

Albert Einstein      Albert Einstein (1879-1955) was probably the most famous scientist who ever lived on this planet, and as famous as he, was his Relativity Theory (Well, at least in the scientific community) : grossly this theory says that gravity is nothing more than the curvature of the space-time (a mathematical identity where the space and time are trated as the same in a four-dimensional manifold). Spacetime Curvature      Although it is his masterpiece, this did not yield a Nobel Prize: the relativity theory is in fact the most accurate theory by the experiments carried out of all times, it predicts gravitational waves, time dilatation, Black Holes.     In 1905, Einstein published four important papers, between these papers there was the start of the special relativity theory in addition to what expl
