Black holes from yesterday to today🕳🌌
Mysterious, omnipresent in popular culture, especially in science fiction films like Interstellar. Are they really these vacuum cleaners of matter and light, these creators of spaghetti as we sometimes hear?
⏱So, for the next hour, we are going to take stock of the history and science of black holes with two physicists from the CEA: one a theoretician, Antoine Bourget, who works at the Institute of Theoretical Physics at the CEA in Saclay, and the other an observer of black holes and author of a book on black holes and the hidden face of the Universe, David Elbaz, who works at the Institute for Fundamental Research on the Laws of the Universe at the CEA in Saclay. Both of you, with your complementary approaches, will answer some of the big questions we have about black holes.
