Max Tegmark, a physicist championing the Mathematical Universe Hypothesis, argues that reality is fundamentally mathematical. Scott Aaronson, a theoretical computer scientist, delves into the implications of viewing the universe as a computer and explores limits on computation from physics. Silvia Jonas, a mathematical pluralist, discusses the set-theoretic multiverse and the independence of mathematical truths, including the continuum hypothesis. Together, they tackle profound questions about the nature of mathematics and its connection to reality.

Episode notes
Physical World As Mathematical Structure
- Max Tegmark argues that physical properties are ultimately numerical and mathematical in nature.
- He concludes that everything, including space and particles, can be a single mathematical structure.
Change Fits A Timeless Math Picture
- Tegmark reconciles change with timeless math via Einstein's spacetime picture.
- He says our dynamic experiences correspond to unchanging four-dimensional shapes in a mathematical structure.
Ask Precise Computational Questions
- Scott Aaronson suggests reframing 'is the universe a computer' into precise computational questions.
- Ask what the universe can compute, how many bits it stores, and which problems it can or cannot solve.
