Einstein thought quantum theory was 'silly.' Heisenberg believed reality is nothing but possibilities. As Sabine Hossenfelder explains, the real challenge is still ahead: reconciling quantum mechanics with general relativity. Can we ever unite the two pillars of physics?

Why quantum theory could have a fractal structure: explained in 83 minutes. The notion of true quantum nonlocality is absurd. In the latest episode of the Quantum Foundations Podcast, Prof Tim Palmer from the University of Oxford suggests that there is a hidden assumption in standard quantum mechanics, and dropping it will save us from this absurdity. Namely, the reality of counterfactuals: the physics of what could have happened but did not. Inspired by chaos theory and the fractal structure widespread in atmospheric physics, Palmer has developed a new underlying structure for quantum theory, with radical implications for our fundamental principles of quantum physics; the limits of quantum computation; and perhaps even the search for quantum gravity.

Physicists are still working on how to make general relativity and quantum mechanics consistent. But there's one problem where they are confident they've made the two theories work together: how many bits of information can you store in a black hole?

Well this is one of the worst takes I've ever heard from Sabine Hossenfelder - that Eric Weinstein's theory is bad, but no worse than any other theory in academic theoretical physics, and physicists won't take Eric seriously because they're "scared" he will expose them

Harvard physicist Jacob Barandes returns with a groundbreaking insight that could reshape quantum theory. By questioning a single hidden assumption, Jacob bridges the gap between classical probability and quantum mechanics. This ‘mathematical accident’ challenges the foundations of Bell’s Theorem, dissolves the measurement problem, and opens a path to a realist interpretation of quantum physics. This episode is a rigorous journey through stochastic processes, non-locality, and the future of theoretical physics.

Physicist Yakir Aharonov argues that the standard story of quantum mechanics is wrong, proposing a time-symmetric “two-state vector” view in which reality is defined by wavefunctions from both past and future. He explains weak measurements (information without collapse), nonlocal dynamics behind interference, and phenomena like the “quantum Cheshire Cat.” Aharonov recounts the birth of the Aharonov–Bohm effect, why gauge potentials mislead about locality, and how pre and post-selection restore causal insight without determinism. He shares memories of Bohm, Heisenberg, and Feynman, touches on gravitational and non-Abelian AB analogs, and lays out why a clear narrative—not just math—is essential to understanding quantum theory.

Hear physics laureate William Phillips speak about how hard it is to predict what quantum mechanics can be used for in the future. Similarly, it was just as hard to predict what it was to be used for 100 years ago. Hear the full conversation: #NobelPrize

Elite physicists are drawn to statistical mechanics because it serves as the "third pillar" of modern physics, bridging the gap between microscopic dynamical laws and the macroscopic world. Albert Einstein is often called the "grand master" of this field because he independently derived the foundations of statistical mechanics between 1902 and 1904, using these principles to prove the existence of atoms and unlock the secrets of quantum reality.

Will we ever know how the universe began? Acclaimed theoretical physicist Sabine Hossenfelder Sabine Hossenfelder argues that not only is discovering the universe’s origins an impossible task, but one that she doesn't consider worth pursuing at all. Instead, theories for the beginning of the universe are merely stories we tell ourselves. In this debate, she joins theoretical quantum physicist Ivette Fuentes and philosopher of science James Ladyman to explore the various lenses through which we perceive and study the cosmological world of the universe.

Quantum theory appears to allow some kind of connection between entangled particles, but not enough to send messages. Prof Antony Valentini argues this is a conspiracy: there must be something deeper than quantum, where nonlocality can actually be used to send messages, but it is hidden from view in standard quantum experiments. In this episode of the Quantum Foundations Podcast, Valentini uses Pilot-wave theory to explain the physics of the nonlocal subquantum world. He discusses various ways that the theory could be experimentally tested, by looking for signatures of violations of the Born rule in extreme environments, such as the early universe. He also discusses the radical technological implications of subquantum physics, if we were able to harness it. Watch on YouTube or listen on audio platforms!

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.

This is a careful lecture that can be followed with zero background knowledge. Einstein thought he'd caught quantum mechanics in an act of spookiness — this podcast asks whether he was even worried about the right thing. Tim Maudlin, professor of philosophy at NYU and a leading philosopher of physics, delivers a rare full lecture tracing Einstein, EPR, and the road to Bell's theorem. The central claim: Einstein's real objection was never determinism — "God does not play dice" is a red herring — but non-locality, which he inferred rather than assumed. Maudlin traces the argument from Einstein's overlooked 1927 Solvay objection through the EPR paper's criterion of reality, showing why Bohr's famous reply never actually answered it.

Why has the unification of Quantum Mechanics and Relativity eluded physics for a century? The barrier isn't a missing force, a new particle, or a hidden dimension. The truth is much more devastating: we are committing a fundamental mathematical error called "basis confusion." The answer is a single geometric structure: the ℂH²/ℂP² compact-dual object. 🧵

We definitely live in a simulation. PROOF the we only see code not solid objects with our eyes. The phrase "everything is energy and nothing is solid" reflects modern physics, especially quantum mechanics, showing that matter isn't solid but vibrating energy fields; atoms are mostly empty space with particles as energy waves, not tiny balls, creating the illusion of solidity through electromagnetic interactions that our brains interpret, revealing reality as a dance of frequencies and potentials, not fixed objects.

The Einstein Test for AGI. Vishal Misra: “You take an LLM and train it on pre-1916 physics and see if it can come up with the theory of relativity.” “If it does, then we have AGI.” “It’s a high bar, but we should have high bars.” “At the time of Einstein, there were a lot of clues that Newtonian mechanics, there was something missing.” “But until Einstein came up with a new representation of the spacetime continuum, we were stuck.” “If you had a model that just looked at correlations and such... it would not have come up with the beautiful equation that Einstein came up with.” Vishal Misra with martin_casado
