Thomas Hertog

Thomas Hertog is a Belgian theoretical physicist and cosmologist at KU Leuven. A close collaborator of the late Stephen Hawking, he co-developed the "no-boundary" theory of the universe's origins. Hertog is best known for his groundbreaking book "On the Origin of Time," which presents a radical new vision of cosmology rooted in his decades of collaboration with Hawking. Drawing on cutting-edge physics, the book explores how the universe — and the laws of nature themselves — evolved from the Big Bang. Hertog is celebrated for his ability to make profound scientific ideas accessible to a broad audience.
