In this insightful conversation, Sabine Hossenfelder, a theoretical physicist and author of 'Existential Physics', tackles profound questions about our existence. She challenges commonly held views on free will and determinism while exploring the tantalizing idea of Boltzmann brains—consciousness arising spontaneously in an eternal universe. Hossenfelder also discusses the complexities of the universe's origins, the nature of mathematical reality, and the evolving perspectives on artificial intelligence, inviting listeners to rethink the fabric of reality.

Episode notes
Simulating Reality
- The simulation hypothesis, suggesting reality is a computer program, faces scientific scrutiny.
- It implies a programmer and requires an algorithm to reproduce observations, which currently doesn't exist.
Creating vs. Simulating Universes
- Creating a universe may be possible, but simulating one is different.
- Creating involves a bubble pinching off, uncontrolled and unprogrammable, unlike a designed simulation.
Free Will and Physics
- Free will doesn't exist given current physics.
- Fundamental laws combine determinism with random quantum events, neither supporting free will.
