WebThe effect of the total gravitational field of the Einstein model on the test particle is given by the equation of geodesy (2.5a). Substituting static metrics (5.5) into the geodesic equation body which is at that moment stationary relative to the surrounding mass, we obtain d 2 x i /dt 2 = 0, so the total gravitational field (space-time metric) in Einstein's universe cannot … WebIn 1543, Copernicus suggested the sun was at the center of the cosmos. However, it was centuries before a sun-centered model became widely accepted. The history of science is often thought of as a procession of discoveries and advances. This obscures the complex stories of how theories and models can compete and coexist over long periods of time. … twitch attente

On first learning of Edwin Hubble's discovery of a linear relation between the redshift of the galaxies and their distance, Einstein set the cosmological constant to zero in the Friedmann equations, resulting in a model of the expanding universe known as the Friedmann–Einstein universe. In 1932, Einstein and De Sitter proposed an even simpler cosmi…
