Lawrence Krauss is a renowned theoretical physicist, bestselling author, and celebrated lecturer who has greatly contributed to various areas of physics and cosmology. Krauss’s significant scientific contribution includes the 1995 proposal that most of the Universe’s energy resides in empty space, confirmed in 1999 and awarded a Nobel Prize in 2011. He built top-ranked Physics Graduate Research Programs and created pioneering initiatives like the Center for Education and Research in Cosmology and Astrophysics, and a Masters Program in Physics Entrepreneurship. As a part of his tenure at Arizona State University, he led the Origins Project and podcast, an internationally recognized initiative fostering transdisciplinary workshops and public engagement events on topics like the origins of the universe, human origins, consciousness, and culture. “The Edge of Knowledge” represents the culmination of Krauss’s quest to unravel the mysteries of the universe. In it, he takes us on an enthralling journey, meandering from the vast reaches of the cosmos to the intricate details of life itself. But this is more than just a voyage through the known; it is an invitation to explore the “unknown unknowns” that await us at the very edge of our comprehension. With “The Edge of Knowledge”, Lawrence Krauss offers more than just a book. He provides a compass for those eager to venture into the uncharted territories of science and an inspiration for all who believe in the power of knowledge to transform our understanding of the universe. In this interview, I speak to Lawrence Krauss, theoretical physicist, bestselling author, and President of the Origins Project. We discuss some of the biggest questions facing our civilisation including the nature of time, space, and the universe.
