Philosophers and physicists discuss the profound question of why there is something instead of nothing, exploring ideas like necessary existence, the role of value, consciousness creating the universe, and ultimate explanations like theism and materialism. Guests include John Leslie, Bede Rundle, Max Tegmark, Simon Blackburn, Quentin Smith, Victor Stenger, Peter van Inwagen, John Polkinghorne, Richard Swinburne, and Paul Davies.

Physicist Max Tegmark, J. Gott, Juan Maldacena, Fotini Markopoulou, and philosopher John Leslie explore the interconnectedness of space and time as part of the same entity. They discuss the challenges of reconciling quantum theory with the continuous nature of space in general relativity. The podcast also delves into the cosmic particle smashing nature of the early universe, challenges the notion of the disappearing past, and contemplates the intricate relationship between space and time as active participants in reality.
