- 22 minutes 38 secondsCurt Jaimungal: What is Existence, Exactly?
I personally subscribe to The Economist. TOE listeners get 35% off the annual subscription. No other podcast has this! https://economist.com/TOE Does Batman exist? Not really—but proving he doesn't turns out to be a logical minefield. This episode tackles negative existentials: why saying "X doesn't exist" seems to require referring to X in the first place. We trace the debate from Russell's theory of descriptions, through Kripke's devastating critique in Naming and Necessity, to Meinong's radical claim that non-existent objects still populate our domain of discourse. Plus: null pointer exceptions as computer science's Meinongianism, why AI struggles with fictional facts, and why three competing theories—descriptivism, Meinongianism, and abstract realism—each come with a steep philosophical price tag. I hope you enjoy.

No other podcast has this! https://economist.com/TOE This is a podcast all about time: depending on how you look at it, that's either unnerving or exhilarating. Professor Simon Saunders — Emeritus Fellow at Merton College, Oxford, and one of the most celebrated philosophers of physics alive — goes deep on what time actually is, why special relativity demands a block universe, and what any of this has to do with the Many Worlds Interpretation. Why doesn't space inherit the paradoxes of time? What's really missing from the block universe picture (and is it the same thing missing from quantum probability?) Saunders argues that Bell inequality violations aren't evidence against locality but evidence for Many Worlds, presents a novel derivation of the Born rule from a single physical postulate, and sketches a quantum version of Leibniz's monadology as a possible path through the mind-body problem. I hope you enjoy.

Sign up for your one-dollar-per-month trial today at http://shopify.com/theories - I personally subscribe to The Economist. TOE listeners get 35% off the annual subscription. No other podcast has this! https://economist.com/TOE This is a breaking podcast. We're premiering a new paradigm for quantizing 4D gravity here first, without strings. Neil Turok — inaugural Higgs Chair at Edinburgh, former director of Perimeter Institute, and 2026 Fellow of the Royal Society — believes quantum gravity may not require strings, extra dimensions, or a multiverse. The key: a 1970s theory called quadratic gravity, long abandoned over two seemingly fatal problems. Turok and Bateman argue both problems dissolve — one by reinterpreting a classical instability as ordinary gravitational expansion, the other by a subtle tweak to the Born rule that allows quantum states of negative norm without ever producing negative probabilities. One quiet assumption, Turok argues, underpins decades of string theory's necessity. Drop it, and the whole case for a multiverse unravels. Neil graciously gave me a sneak peek at his and his PhD student Sam Bateman's new research. Bleeding edge! I hope you enjoy.

He argues AI alignment isn't merely unsolved but fundamentally under-defined: no agreed-upon values, no way to formalize them even if there were, and no mechanism for enforcing them on something smarter than its creators. His strongest argument isn't a doom scenario, it's that you cannot indefinitely control something smarter than you.

He suspects space-time isn't fundamental at all, that geometry itself might be what entanglement looks like from the inside. The singularity isn't a place, it's a name for everything we don't yet understand. I hope you enjoy it.

Philosopher, provocateur, self-described pessimist, he insists on something most thinkers shy away from: that freedom isn't the absence of necessity — it's the moment you choose what you fundamentally are. The fall comes first. Paradise was never real. Reality is the gap, not either side of it.

Why can't local agreement scale to global truth? At the Mind at Large consciousness conference, hosted by the Center for Process Studies, I make the case using sheaf theory and physics — breaking down consciousness, free will, and the hard problem to show why sincerity beats any polished, totalizing philosophy.

Co-author with Stephen Hawking of the singularity theorems, he's spent decades insisting on something most physicists won't touch: that reductionism is simply — patently — false. Physics doesn't decide outcomes. Context does. The thermostat sets the temperature. The algorithm tells the electrons what to do. The physics is the servant, not the master.

For 30 years he's measured aspects of physics others wouldn't touch: Bohmian trajectories, Heisenberg's disturbance bound (he showed it was wrong), even where the photon is inside the double slit. His lab measured negative time, and it keeps reappearing across different experiments.
