Acclaimed theoretical physicist and science writer Lawrence M Krauss, in conversation with philosopher AC Grayling, tackles five fundamental mysteries at the forefront of science today: time, space, matter, life, and consciousness. He speaks about the big questions that will shape the state of science for the decades ahead, and why exploring the mysteries that define the scientific forefront – known as the threshold of the unknown – will help us gain a deeper understanding of just how far science has progressed. As well as The Known Unknowns: The Unsolved Mysteries of the Cosmos, Krauss’s books include The Physics of Star Trek and The Physics of Climate Change, and he hosts The Origins podcast.
