The latest news about black holes
Black holes are among the most fascinating objects predicted by Einstein's theory of gravity. Their gravitational pull is so strong that nothing, not even light, can escape from them (hence the name "black"). Black holes have been put recently in the limelight with the 2020 Nobel prize in physics awarded to pioneers in black hole physics, both on the theoretical side (Penrose) and on the observational side (Genzel and Ghez).
What is a black hole? How can one observe a black hole if it is black? Do they really destroy any information that’s thrown at them? Come and find out. The talk will explain what black holes are, their main properties and their astrophysical relevance. Conceptual puzzles related to black holes (Hawking radiation, wormholes, singularity) will also be addressed.
Have no fear. After the talk, we will cross the horizon altogether to the bright and delightful melodies of Las Lloronas, while enjoying the highlights of our cocktails menu, including the famous « Black Hole ».
Marc Henneaux is professor at the Collège de France (Paris) and professor emeritus at the Université Libre de Bruxelles. He also serves as Director of the International Solvay Institutes for Physics and Chemistry. His research is devoted to the study of the fundamental physical forces and their symmetries with a particular emphasis on gravity, a field to which he made major contributions. He was awarded various prizes, including the Francqui Prize (2000), the Humbold Prize (Germany 2009), the Bogoliubov Prize (Russia 2014), the FRS-FNRS Quinquennal Prize for exact sciences (2015) and two ERC advanced grants. Marc Henneaux was created "Baron" in 2015 by Philippe, King of the Belgians.
