In this episode I speak with the theoretical physicist and New York Times bestselling author Lawrence Krauss (https://lawrencekrauss.substack.com) about, among other things, the so called Many Worlds Interpretation of quantum mechanics. In order to do this, I mainly draw from the work of the theoretical physicist David Deutsch (https://www.thebeginningofinfinity.com / https://www.daviddeutsch.org.uk).
