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.
Las Lloronas starts in the streets of Brussels in the winter of 2017, as a temporary and spontaneous project. Sura Solomon (BE/USA), Amber in ‘t Veld (ES/NL) and Marieke Werner (DE) meet years earlier, sharing a passion for sociology, activism and art. This passion now translates and transforms into music. Reflecting their experiences and origins, their work merges acoustic music and slam, giving birth to multilingual and intimate feminist poetry. Harmonies happen effortlessly, provoking a musical crush between the three voices. This is what drives them to pursue the project professionally.
Inspired by musicians such as Lhasa de Sela, Noname and Ibey, Las Lloronas assert their intimate lyrics, they soak in harmonies and melancholic melodies. Three voices travel through Spanish folk and Hip Hop rhythms, Klezmer sonorities and Blues, somewhere on the edge between lament, daydream and battle cry. In their performance, voices, a clarinet, a guitar, an accordion and a ukulele share a moment of powerful vulnerability.
