Tom Campbell

Tom Campbell is a physicist and the author of the My Big TOE trilogy. He worked in technology development and risk analysis, and developed a theory of everything in which consciousness is fundamental and physical reality is a kind of simulation. His proposals are speculative, and they are discussed on the programme as ideas to examine, not as established science.

He has been a guest twice. One conversation sets out the theory and asks whether we are living in a simulation. The other follows its consequences, including altered states of consciousness, near-death experiences and what it might mean to leave the simulation.
