Podcasts about Quantum gravity

Did evolution never give us the ability to see reality as it actually is? Neil deGrasse Tyson and co-hosts Chuck Nice and Gary O'Reilly sit down with cognitive scientist Donald Hoffman to explore what neuroscience, evolutionary game theory, and consciousness suggest about the nature of reality itself.

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.

One of the major obstacles to understanding quantum mechanics is the difficulty we have in simply accepting what the theory itself is telling us. The problem is that we know what the everyday world looks like -- stuff, arranged in space, evolving through time. So we can't resist the temptation to impose that picture on the quantum description, even if it's not actually there. In this solo episode I talk about what it means to take quantum mechanics at face value, and the difficult work involved in understanding how the everyday world of our experience fits into the picture.

There is something special about gravity. After decades of effort, there is still no convergence on the right way to reconcile Einstein's theory of general relativity with the framework of quantum mechanics. But a number of intriguing ideas have arisen along the way, including black hole radiation, the wave function of the universe, the AdS/CFT correspondence, and the role of quantum information theory. Theoretical physicist Daniel Harlow has made significant contributions to our understanding of information loss in black holes; in this conversation we turn those insights onto quantum cosmology, with potentially significant implications for how quantum mechanics itself works.

What are holographic dualities, and is our universe really a hologram? In this episode of the podcast, I speak with Sabrina Pasterski, a faculty member at the Perimeter Institute for Theoretical Physics. Sabrina has attracted significant media attention over the years and has even been compared to figures like Einstein. I ask her what it was like to grow up under such intense public hype while still finding her footing as a scientist. We also explore whether the media risks being irresponsible when it constructs prodigy narratives — and what that means for young, brilliant minds trying to navigate their own paths. We then turn to the major challenges in quantum gravity — a field that lacks direct experimental data and often relies on internal consistency. Sabrina shares insights from her work in Celestial Holography, which seeks to understand quantum gravity through dual descriptions: simpler, non-gravitational theories that live in lower-dimensional spaces. ►Watch on YouTube: https://youtu.be/Uff-40hOOHw ►For more information about Sabrina and her work: www.youtube.com/@PhysicsGirl-com https://physicsgirl.com/ https://perimeterinstitute.ca/people/sabrina-pasterski https://en.wikipedia.org/wiki/Sabrina_Gonzalez_Pasterski

The self and the world We tend to think of ourselves as observers of the world and experience as something different from the material stuff that makes up reality. Yet at the same time as human beings, we are at once part of the universe and part of that reality. And this profoundly puzzling relationship, that we are both part of something and yet separate from it, has been at the centre of Western thought. Materialists claim there is only physical material. But if so, thought, experience, and consciousness become illusory. Idealists argue there is only consciousness, but then it is reality that becomes an illusion. While dualists hold that both the self and the world exist, but that the connection between the two is mysterious. Is the self part of the world or necessarily outside of it? Was Kant right that the distinction between subject and object is necessary for experience to be possible? Or are these deep metaphysical questions beyond us, and our theories and language incapable of uncovering the ultimate state of things?Slavoj Žižek is one of the most famous philosophers in the world and is the author of more than 50 books, including most recently at the time of the debate Zero Point. Alenka Zupančič is a leading Lacanian philosopher and social theorist. She is a professor at The European Graduate School and at the University of Nova Gorica. Joining from America, Carlo Rovelli is a leading theoretical physicist, the author of several best-selling books, and a founding figure in the field of quantum gravity. His recent book, Reality Is Not What It Seems, has ethical implications for the nature of the self and personal identity. Jack Symes hosts.

This episode of the Physics World Weekly podcast features Alex May, whose research explores the intersection of quantum gravity and quantum information theory. Based at Canada's Perimeter Institute for Theoretical Physics, May explains how ideas being developed in the burgeoning field of quantum information theory could help solve one of the most enduring mysteries in physics – how to reconcile quantum mechanics with Einstein's general theory of relativity, creating a viable theory of quantum gravity. This interview was recorded in autumn 2025 when I had the pleasure of visiting the Perimeter Institute and speaking to four physicists about their research. This is the last of those conversations to appear on the podcast. The first interview in this series from the Perimeter Institute was with Javier Toledo-Marín, “Quantum computing and AI join forces for particle physics”; the second was with Bianca Dittrich, “Quantum gravity: we explore spin foams and other potential solutions to this enduring challenge“; and the third was with Tim Hsieh, “Building a quantum future using topological phases of matter and error correction”.   This episode is supported by the APS Global Physics Summit, which takes place on 15–20 March 2026 in Denver, Colorado, and online.

Titans of Science is all about showcasing science superstars making huge breakthroughs and giant leaps foward in their scientific realms. In this episode, we turn the telescope around around to consider the extremely strange effects that kick in when physics shrinks down to the atomic scale. We are, of course, taking a tour through the world of quantum mechanics, and our guide is the physicist, writer and broadcaster Paul Davies. Like this podcast?

To him, the universe is a cosmic pinball machine. Every ball follows a fixed path. No randomness. No mystery. We only invented quantum mechanics to cope with our ignorance. In his picture, there are no real numbers. No wave functions. No superposition. Just discrete states clicking forward, one after another, beneath everything we see.

Quantum gravity is one of the biggest unresolved and challenging problems in physics, as it seeks to reconcile quantum mechanics, which governs the microscopic world, and general relativity, which describes the macroscopic world of gravity and space-time. Efforts to understand quantum gravity have been focused almost entirely at the theoretical level, but Monika Schleier-Smith at Stanford University has been exploring a novel experimental approach — trying to create quantum gravity from scratch. Using laser-cooled clouds of atoms, she is testing the idea that gravity might be an emergent phenomenon arising from quantum entanglement. In this episode of the Joy of Why podcast, Schleier-Smith discusses the thinking behind what she admits is a high-risk, high-reward approach, and how her experiments could provide important insights about entanglement and quantum mechanical systems even if the end goal of simulating quantum gravity is never achieved.

What is Holography and how does it help us Quantize gravity? In this conversation I speak with Pedro Vieira, one of the worlds leading experts on holographic dualities and their application in quantum gravity. We start our discussion with a few standard but big questions, like why is quantum gravity difficult, what is quantum field theory, and what is gauge symmetry. We then dive into the topic of holography, which in broad and provocative terms is the idea that our universe and everything in it might be a hologram projected from some lower dimensional quantum theory. That is, there might be a duality between the mathematics that describes our world including gravity and the mathematics that describes a world with quantum mechanics and without gravity in one dimension lower. If such a duality were true, then it might provide a radial way of side stepping all of the usual difficulties of quantizing gravity.  ►Watch on YouTube: https://youtu.be/FdpVxLq_PAk ►Find out more about Pedro here: https://perimeterinstitute.ca/people/pedro-vieira  https://inspirehep.net/authors/1027784  These conversations are supported by the Andrea von Braun foundation (http://www.avbstiftung.de/), as an exploration of the rich, exciting, connected, scientifically literate, and (most importantly) sustainable future of humanity.

There is a strong tradition in Islamic culture to intertwine art and mathematics. This talk is about how this tradition has influenced the speaker's work on how physics reveals the structure of the universe, mathematics is the language for this and opens a way for art to help understand things in string theory, which connects quantum mechanics with general relativity via progress toward a theory of quantum gravity. Speaker Sylvester James Gates, Jr., Brown Theoretical Physics Center Director and Distinguished University Professor in Physics, University of Maryland

Nassim Haramein was born in 1962 in Geneva, Switzerland. Haramein's father was a scholar at the University of Geneva completing a thesis under the guidance of the notable Jean Piaget, considered one of the fathers of child psychology. Although offered a position at the prestigious Piaget Institute, his father choose to accept a position at the child psychology department of the University of Montreal becoming the director of the orthopedagogy department. As a result, Nassim Haramein grew up in the Canadian environment and wilderness most of his childhood leading to an early successful career in the ski and mountaineering industry affording him a significant amount of time to observe and ponder the mechanics of the natural world. Starting in the early 1980's, Haramein developed a significant interest in sciences and philosophy, specifically in physics and the nature of the material world. This led him to a deep and dedicated self-study of both the foundation of general relativity and quantum theory. After some ten years of intensive study and exploration, Haramein started lecturing in various contexts both in Canada and the USA. This resulted in a first physics paper published in 2004 with co-author, prominent physicist, Dr. Elizabeth Rauscher "The Origin of Spin": a consideration of torque and Coriolis forces in Einstein's field equations and grand unification theory. Eventually Haramein published a seminal paper entitled “The Schwarzschild Proton” which described the proton as having equivalence energy and force structure to a mini-black hole due to quantum vacuum fluctuations. With the event of the holographic principle in physics, Haramein eventually published a series of papers describing the source of mass and the confining forces of subatomic particles being related to quantum vacuum fluctuations in a formalism dubbed the holographic mass solution. This peer-reviewed paper entitled “Quantum Gravity and the Holographic Mass”, published in 2013, employed a generalized holographic principle, relating the proton's charge radius and mass, and predicting a radius differing from the Standard Model by 4%. This proton radius was later validated through experiments at the Paul Scherrer Institute and is now the official CODATA value. From 2013 to present, Haramein publishes multiple papers addressing the nature of the electron and the so called missing mass issue in cosmology as well as a first paper on biophysics relating the structure of spacetime to the biological organizations of the brain entitled “The Unified Space Memory Network: from Cosmogenesis to Consciousness”. In September 2023, Haramein et al. pre-published a paper entitled “The Origin of Mass and Nature of Gravity” detailing the correlation functions related to the dynamic of the quantum vacuum and demonstrating that the mass and confining forces are the result of a screening mechanism of the density of the vacuum at the Planck scale. This initial paper is the first in a series that set the foundation for the unification of forces and physical constants which will follow.

A few weeks ago, I released a video about whether string theory's biggest competitor, Loop Quantum Gravity, might have suffered a fatal blow. The video sparked a lively debate across YouTube, with creators like Sabine Hossenfelder and Phil Halpern making reaction videos and Carlo Rovelli even reaching out to me personally, asking me to take it down. Now, I want to clarify the situation and share my perspective on whether Loop Quantum Gravity is truly on its last legs—or if there's more to the story.  Tune in to the Loop Quantum Gravity War! Key Takeaways:  00:00 Intro 01:02 My initial video on loop quantum gravity  03:42 Quick recap of my correspondence with Carlo Rovelli 04:32 The problem with string theory and loop quantum gravity 09:25 Reacting to Sabine's video  13:11 My final thoughts  Additional resources:  ➡️ Check out the videos referenced:

"The 20th century was the interaction of geometry and physics, and the 21st century is the interaction of number theory with physics." This intriguing insight comes from our recent discussion with Yang-Hui He from the London Institute of Mathematical Sciences.  Yang told us an amazing story about the flow of ideas between mathematics and physics, that involves some of the most celebrated achievements in the last century. Yang-Hui He (Photo Rajarshi Maiti – CC BY-SA 4.0) You can find out more about the ideas we discussed with Yang in this podcast in the accompanying articles String theory: A promise from physics and String theory: Convincing mathematics. And stay tuned for the second part of our conversation with Yang in the next episode!

Quantum gravity research is inspired by experiment — all of the experimental data that supports quantum mechanics, and supports general relativity — but it's only inspiration, not detailed guidance. So it's easy to “do research on quantum gravity” and get lost in a world of toy models and mathematical abstraction. Today's guest, Andrew Strominger, is a leading researcher in string theory and quantum gravity, and one who has always kept his eyes on the prize: connecting to the real world. We talk about the development of string theory, the puzzle of a positive cosmological constant, and how black holes and string theory can teach us about each other.
