David Elbaz - The Secrets of Light

The spectacular and ever more distant images transmitted by space telescopes amaze us, but the cosmic landscape could have been very different. If the Universe had been composed of matter incapable of radiating, there would be no stars, no galaxies, and no life on Earth. Light, the true keystone of our origins, has allowed matter to organize itself since the Big Bang, 13.8 billion years ago.
David Elbaz, renowned astrophysicist and expert in the formation and evolution of galaxies, explores the genesis of the Universe and the major existential questions it raises. Drawing on recent images and videos captured in space, he questions the role of chance and the underlying logic that could guide the cosmos. Author of the award-winning book La plus belle ruse de la lumière (Prix Ciel et Espace 2022), he shares a captivating reflection on light and its fundamental role.
