UE General relativity and cosmology



The General Relativity and Cosmology module gives an introduction to one of the two most revolutionary major theories of the 20th century, Albert Einstein's General Theory of Relativity, and its application to cosmology.

After a brief review of Special Relativity, the fundamentals of General Relativity will be developed, based on the equivalence principle (local equivalence between gravitation and accelerated reference frames). Geometric formalism will be presented in a simplified manner accessible to physicists, along with its application to the gravitational field of a central mass (Schwarzschild metric) and to gravitational waves. Subsequently, this theory's application to the history of the Universe will be developed, with a presentation of the concepts and observations that forged modern cosmology: cosmic background radiation, primordial nucleosynthesis, cosmological constant, formation of major structures, as well as a brief look at current questions about the early Universe (inflation, phase transitions, quantum gravity).
