L’univers est-il fini ou infini ? | Marc Lachièze-Rey

Over the centuries, the question of the shape and size of the universe has been a subject of ongoing debate. Numerous answers have been proposed, and just as many paradoxes raised. One certainty remains: the universe is not a physical object like any other. Marc Lachièze-Rey, CNRS Emeritus Research Director and specialist in fundamental theoretical physics, is the author of numerous works, including "Initiation to Cosmology" (Dunod, 2020) and "On Infinity: Cosmic Horizons, Multiverses, and Quantum Vacuum," co-authored with Jean-Pierre Luminet (Dunod, 2016).
