L’Univers a-t-il vraiment eu un commencement ?

The Big Bang is part of our collective imagination. We often picture this event as a primordial explosion marking the birth of the universe 14 billion years ago. This inevitably raises a question: What came before? Yet this idea of an absolute beginning is as much a linguistic trap as it is a misinterpretation of the equations. Without disputing the scientific facts, physicist Jean-Marc Lévy-Leblond invites us to shift our perspective. Through an accessible and rigorous exploration at the intersection of science and philosophy, he demonstrates how a more subtle reading of physics allows us to eliminate the idea of an “origin” of the world. An invitation to rethink our relationship with time, the infinite, and the language of science. By **Jean-Marc Lévy-Leblond**, theoretical physicist and professor emeritus. Author of numerous reference works, he devotes his work to physics, epistemology, and the relationships between science, culture, and citizenship. He is the editor-in-chief of the journal _Alliage_.
