The Centennial of Einstein’s 1915 Theory of General Relativity

Photos of the Month — November 2014

Next year marks the 100th anniversary of Einstein’s publication of three papers on the theory of general relativity. These three publications introduced a new framework for physics and proposed new concepts of space and time. In 1915 Karl Schwarzschild proposed the first exact solutions to Einstein’s field equations. These solutions would lead to the concept of black-holes. Future works from Hilbert and Hubble were based on Einstein’s findings. On the basis of observations carried out with the 100-inch Hooker telescope at the Mt. Wilson Observatory between 1924 and 1929, Hubble showed that the universe was expanding and extended well beyond the Milky Way. Einstein’s theory would contribute to physics discoveries for years to come. We’re celebrating the upcoming anniversary with images reflective of one of Einstein’s greatest accomplishments.
