Titre |
General Relativity, Gravitational Waves and Black Holes |
|
Résumé |
General Relativity was finalized by Albert Einstein a century ago, in 1916. Two of the most novel
predictions of General Relativity were also discovered in 1916 : Black Holes (Schwarzschild, January 1916)
and Gravitational Waves (Einstein, June 1916). It took more than 50 years to grasp the physical significance
of these theoretical discoveries. The recent discovery of GW150914 by the two LIGO interferometers has
brought the first direct evidence for the existence of black holes, and has also been the first observation of
gravitational waves in the wave-zone. After reviewing the conceptual foundations of General Relativity, the
talk will explain the theoretical developments on the motion and gravitational radiation of binary black
holes that have been crucial in interpreting the LIGO event GW150914 as being emitted by the coalescence
of two black holes. Some of the mysterious physical properties of black holes will also be reviewed. |
