Many people think physics / reality is either guided by a probabilistic distribution or is “determined.” Actually, there’s a third, far‐more unsettling option. Curt Jaimungal explains why Einstein’s general relativity isn't actually deterministic. He discusses how Cauchy horizons and closed time-like curves break predictability, showing that math and physics don't always guarantee a set future for our universe. This is a solo deep‑dive. One that he's been meaning to make for a while.

Professor John Donoghue explains why quantum physics and gravity actually work perfectly together. He tackles quadratic gravity, effective field theory, and random dynamics, arguing that grand unification and naturalness aren't required for a theory of everything.

Physicist Nir Lahav joins me to argue that the hard problem isn't hard so much as confused—a consequence of treating consciousness as an absolute property rather than a relative one. Drawing on the principle of relativity, he proposes that subjective experience is a genuine physical property that manifests only from within a cognitive system's own internal simulation, where the felt sense of good and bad becomes as real as location in space. This conversation requires zero prior background in physics or philosophy. Every concept is built from scratch.

Curt Jaimungal argues that astrophysicists like Neil deGrasse Tyson and spiritual gurus Deepak Chopra and Thomas Campbell can’t logically claim they don’t hold beliefs. This “Theories of Everything” with Curt Jaimungal episode uses analytic philosophy to show why belief’s vital for understanding physics and consciousness, countering what Thomas Campbell and NASA scientist Nathalie Cabrol say.

What is mathematics, really? Mathematician David Bessis joins me to argue that math isn't about numbers in a Platonic realm or a meaningless game of symbols—it's a cognitive technology for rewiring your brain. We explore why the official definitions of mathematics have been unresolved for 2,300 years, why understanding something means finding it obvious, and how the gap between a beginner and Terence Tao looks less like genetic destiny and more like compound interest on intuition. When asked what mathematics fundamentally is, his answer cuts through millennia of philosophy: it's what happens in your head when you pretend something is true until it feels real.

What if gravity is just entropy in disguise? Professor Erik Verlinde joins me to argue that gravity isn't a fundamental force—it's thermodynamic, emerging from quantum information the way gas pressure emerges from molecules bouncing around. We explore why spacetime may be stitched together by entanglement, and how dark energy and dark matter both pop out automatically without extra particles or parameters. Verlinde explains why the cosmological constant problem is a red herring, and why there may be no final theory of physics. When asked where the universe comes from, his answer is one word: chaos.

What if physics is just the universe learning? Most Theories of Everything episodes are mind‑bending for their math, physics, philosophy, or consciousness implications. This one hits all four simultaneously. Professor Vitaly Vanchurin joins me to argue the cosmos isn't just modeled by neural networks—it literally is one. Learning dynamics aren't a metaphor for physics; they are the physics. Vanchurin shows why we need a three‑way unification: quantum mechanics, general relativity, and observers.

From Ancient Egypt to Leibniz... Brand‑new interview out with Robert Spekkens of the Perimeter Institute, one of the sharpest minds working on quantum foundations. In 2004, he constructed a classical toy theory where your maximum knowledge is always incomplete—and out popped the no-cloning theorem, teleportation, and interference effects Feynman deemed impossible to reproduce classically. Spekkens compares our situation to Egyptian hieroglyphs before Champollion: a category mistake where we treat quantum states as descriptions of reality when they actually describe knowledge of reality. If you’re interested in the topics above, you’ll love this podcast.

Hot off the press, Professor Subir Sarkar makes the case that dark energy doesn’t exist (and he’s not being provocative for its own sake). He’s the former head of Oxford’s particle theory group, serves on the Particle Data Group. Sarkar's group has found that the cosmic acceleration supposedly driving the universe's expansion is directional—not uniform as required by a cosmological constant—appearing only in the direction we're moving through space. He claims the 2011 Nobel Prize-winning discovery rests on a century-old assumption of cosmic isotropy that his data now falsifies at over 5 sigma. "We need to go back to square one."

This is an interview with Stuart Kauffman, one of the founders of complexity theory. He invented random Boolean networks at only 23 years old and helped establish the Santa Fe Institute. Now 86, he makes a striking claim: there is no theory of everything. Kauffman argues that biological evolution creates genuinely new possibilities that cannot be deduced from prior states—paralleling the ancient Chinese Tao more than Plato's Logos. He also believes he's found something new in quantum gravity (and, in his words, "genuinely huge"). He unveils it here for the first time.
