What if the universe was stuck in an eternal cosmic Groundhog Day? Picture traveling backwards through time past the Big Bang only to discover you've looped right back to where you started - like a cosmic snake eating its own tail. Explore the mind-bending possibility that our entire universe repeats itself in endless cycles, where infinite copies of you exist scattered across millions of light years, all having this exact same conversation at different stages of cosmic evolution. Join cosmologist Niayesh Afshordi from the University of Waterloo and Perimeter Institute for Theoretical Physics, and science communicator Phil Halper, fellow of the Royal Astronomical Society, as they dive into Roger Penrose's controversial time loops and the heated scientific battles between cosmologists who engage in academic warfare. Discover the wild world where the universe literally forgets what's big and what's small, why some scientists think this cyclical cosmos is the answer to everything, while others call it pure fantasy - and why both camps might be having religious wars instead of scientific debates. This episode is based on Afshordi and Halper's new book "Battle of the Big Bang: The New Tales of Our Cosmic Origins" from University of Chicago Press, which explores these cosmic battles and 25 different Big Bang models: https://press.uchicago.edu/ucp/books/book/chicago/B/bo244963115.html --- Find out more about Gaby's science fiction short story!

Melvyn Bragg and guests discuss the decisive role of one of the great 20th Century physicists in solving the question of nuclear fission. It is said that Meitner (1878-1968) made this breakthrough over Christmas 1938 while she was sitting on a log in Sweden during a snowy walk with her nephew Otto Frisch (1904-79). Both were Jewish-Austrian refugees who had only recently escaped from Nazi Germany. Others had already broken uranium into the smaller atom barium, but could not explain what they found; was the larger atom bursting, or the smaller atom being chipped off or was something else happening? They turned to Meitner. She, with Frisch, deduced the nucleus really was splitting like a drop of water into a dumbbell shape, with the electrical charges at each end forcing the divide, something previously thought impossible, and they named this ‘fission'. This was a crucial breakthrough for which Meitner was eventually widely recognised if not at first.WithJess Wade A Royal Society University Research Fellow and Lecturer in Functional Materials at Imperial College, LondonFrank Close Professor Emeritus of Theoretical Physics and Fellow Emeritus at Exeter College, University of OxfordAnd Steven Bramwell Director of the London Centre for Nanotechnology and Professor of Physics at University College LondonProducer: Simon TillotsonReading list:Frank Close, Destroyer of Worlds: The Deep History of the Nuclear Age, 1895-1965 (Allen Lane, 2025)Ruth Lewin Sime, Lise Meitner: A Life in Physics (University of California Press, 1996)Marissa Moss, The Woman Who Split the Atom: The Life of Lise Meitner (Abrams Books, 2022)Patricia Rife, Lise Meitner and the Dawn of the Nuclear Age (Birkhauser Verlag, 1999) In Our Time is a BBC Studios Audio Production

By most popular accounts, the universe started with a bang some 13.8 billion years ago. But what happened before the Big Bang? And how do we know it happened at all? Cosmologist Niayesh Afshordi and science communicator Phil Halper offer a tour of the peculiar possibilities: bouncing and cyclic universes, time loops, creations from nothing, multiverses, black hole births, string theories, and holograms. Incorporating insights from Afshordi's cutting-edge research and Halper's original interviews with scientists like Stephen Hawking, Roger Penrose, and Alan Guth, Afshordi and Halper compare these models for the origin of our origins, showing each theory's strengths and weaknesses and explaining new attempts to test these notions. But most of all, Afshordi and Halper show that this search is filled with wonder, discovery, and community—all essential for remembering a forgotten cosmic past. Niayesh Afshordi is professor in the Department of Physics and Astronomy at the University of Waterloo and associate faculty at the Perimeter Institute for Theoretical Physics in Ontario, Canada. His prize-winning research focuses on competing models for the early universe, dark energy, dark matter, black holes, holography, and gravitational waves. Phil Halper is a fellow of the Royal Astronomical Society and a science popularizer. He is the creator of the popular YouTube series Before the Big Bang, which has had several million views. His astronomy images have been featured in major media outlets including The Washington Post, the BBC, and The Guardian, and he has published several papers in peer-reviewed journals.

Einstein's general theory of relativity, plus some reasonable assumptions about the universe and what it's made of, has a remarkable implication: that as we trace cosmic evolution into the far past, we ultimately hit a singularity of infinite density and curvature, the Big Bang. Did that really happen? Einstein's theory is classical, after all, and the world is quantum. And whose to say what assumptions are reasonable? Niayesh Afshordi and Phil Halper have written a new book, Battle of the Big Bang: The New Tales of Our Cosmic Origins, that surveys all of the mind-bending possibilities.Blog post with transcript: https://www.preposterousuniverse.com/podcast/2025/05/26/316-niayesh-afshordi-and-phil-halper-on-the-big-bang-and-before/Support Mindscape on Patreon.Niayesh Afshordi received a Ph.D. in astrophysics from Princeton University.

Metamaterials are special structures made of tiny components that give them unique electromagnetic properties not found in nature. One key feature is a negative refractive index, which enables technologies like "superlenses" for ultra-detailed imaging and "invisibility cloaks." The concept began when Sir John Pendry theorized special rings (SRRs) that could manipulate electromagnetic waves. Later, Sheldon Schultz and David Smith proved this idea with real experiments. Since then, research on metamaterials has rapidly expanded, covering everything from microwaves to visible light. In this talk, Professors Pendry and Smith will share their experiences and discuss how metamaterials have shaped science and technology over the past 25 years.

We will review the beginning of experimental and theoretical studies of moire systems and their evolution up to present. This type of systems represent a new way of “growing” materials, and has tremendous potential both for fundamental physics as well as for applications. Two dimensional periodic crystals, whose separation between atoms is of order angstroms, can be twisted controllably with respect to each other such that they form new “periodicities”, called moire periodicities. In the new “unit cell” we find thousands of atoms of the original crystal. These atoms behave in ways that are incredibly counterintuitive. We show how the controlled twisting of graphene and MoTe2 layers has led to a slew of states of matter not possible in bulk conventional materials. We will show how the collective behavior of thousands of p orbitals in a moire unit cell of graphene can create single Heavy fermion at moire scale, and how the interaction between such fermions can lead to a perfect quantum simulator of an Anderson model. We will then present a catalogue of possible twistable materials and show how a huge variety of strongly interacting models can be realized in twisted homo and hetero twisted bilayers and multilayers of these materials.

How can a binding international treaty be agreed and put into practice, when many parties are strongly tempted to break the rules of the agreement, for commercial or military advantage, and when cheating may be hard to detect? That's the dilemma we'll examine in this episode, concerning possible treaties to govern the development and deployment of advanced AI.Our guest is Otto Barten, Director of the Existential Risk Observatory, which is based in the Netherlands but operates internationally. In November last year, Time magazine published an article by Otto, advocating what his organisation calls a Conditional AI Safety Treaty. In March this year, these ideas were expanded into a 34-page preprint which we'll be discussing today, “International Agreements on AI Safety: Review and Recommendations for a Conditional AI Safety Treaty”.Before co-founding the Existential Risk Observatory in 2021, Otto had roles as a sustainable energy engineer, data scientist, and entrepreneur. He has a BSc in Theoretical Physics from the University of Groningen and an MSc in Sustainable Energy Technology from Delft University of Technology.Selected follow-ups:Existential Risk ObservatoryThere Is a Solution to AI's Existential Risk Problem - TimeInternational Agreements on AI Safety: Review and Recommendations for a Conditional AI Safety Treaty - Otto Barten and colleaguesThe Precipice: Existential Risk and the Future of Humanity - book by Toby OrdGrand futures and existential risk - Lecture by Anders Sandberg in London attended by OttoPauseAIStopAIResponsible Scaling Policies - METRMeta warns of 'worse' experience for European users - BBC NewsAccidental Nuclear War: a Timeline of Close Calls - FLIThe Vulnerable World Hypothesis - Nick BostromSemiconductor Manufacturing Optics - ZeissCalifornia Institute for Machine ConsciousnessTipping point for large-scale social change?

Sir John Pendry is the 2024 Kyoto Prize Laureate in Advanced Technology. He serves as a professor of Theoretical Solid State Physics at Imperial College London. After earning his Ph.D. at University of Cambridge, Pendry's initial research concerned a low-energy electron diffraction theory for examining and measuring the surface of materials for practical purposes. He theoretically demonstrated that materials with electromagnetic properties not found in nature, such as negative-refractive-index materials (metamaterials), can be created by designing microstructures smaller than the wavelength of the target electromagnetic waves. This groundwork helped create innovative materials such as “superlenses” with subwavelength resolution and “invisibility cloaks.” Series: "Kyoto Prize Symposium" [Science] [Show ID: 39990]

Prior to the rise of Nazism, the University of Göttingen hosted most of the top physicists in the world, either as resident or visiting scientists. With us to discuss the history of physics in Göttingen are Tim Salditt, Kurt Schönhammer, and Sarah Köster. In this conversation over tea at the University of Göttingen, we discuss how Göttingen became a focal point of physics, key moments and people during the decades that Göttingen hosted discovery after discovery, and what happened to the assembly of scholars in Göttingen as Germany descended into the abyss of fascism. Tim Salditt and Sarah Köster are both professors of experimental physics in the Institute for X-Ray Physics, and Kurt Schönhammer is a retired Professor from the Institute for Theoretical Physics.

Physicist Matt Strassler drops in to talk about the origins of the universe and how we how what we know.About  our guest:Dr. Matt Strassler is a  theoretical physicist and writer. His research over the past thirty years has mainly been related mainly to the Large Hadron Collider, though he has written many papers on a wide variety of topics in string theory, quantum field theory and particle physics. He has recently completed a new book, called “Waves in an Impossible Sea“, in which, without assuming readers know any science or math, he explains modern physics and its centrality in human experience.

What's it like to stand at the edge of human knowledge, where we don't know what leap forward in understanding the next technological innovation will herald? To find out, Dr. Charles Liu and co-host Allen Liu welcome Dr. Melodie Kao, resident radio astronomer at the Lowell Observatory in Flagstaff, AZ, where Clyde Tombaugh discovered Pluto back in 1930. (And if you're scratching your heads saying, “What's a radio astronomer doing at an optical observatory?” you're not alone. Short answer: Melodie convinced them they wanted one, and that it should be her!”) As always, though, we start off with the day's joyfully cool cosmic thing, the amazing discovery by the NEID Spectrograph at the WIYN telescope at Kitt Peak Observatory of a planet 9 times the mass of Earth orbiting a sun-like star 49 light years away with an orbital period of just 31 days. Melodie explains the precision of the measurement required to discover a planet at that distance, and shares one of her own recent discoveries using a technique called very-long-baseline interferometry (VLBI). In a groundbreaking effort she strung together 39 radio dishes across the northern hemisphere of Earth in a multi-observatory effort to create an Earth-sized telescope (similar to the technique that was used to create the first image of a black hole) and pointed it at a brown dwarf and measured its magnetic fields and radiation belts (like our Van Allen belts). For comparison, the effort was like measuring a pea perched on the Golden Gate Bridge in San Francisco while standing on the Statue of Liberty in NYC. The trio discusses the importance of the discovery of the Van Allen belts, and how that allowed us to plot trajectories that avoided the worst of that radiation for Apollo astronauts on their journeys to the Moon. For our first audience question, Ari from North Greene High School in Tennessee asks, “What is the percentage of possible exoplanets that are similar to the earth's atmosphere, placed in their solar system (within a similar area of their respective Goldilocks zone), gravity, etc.? And how long would it take to hypothetically get to them?” That turns out to be a very complicated question, and Melodie knows someone who has devoted her entire career to answering it. It's one of the questions that drove the creation of the James Webb Space Telescope and is the basis of the Drake Equation. The bottom line, though, is that we don't know yet, and until we find a rocky planet with an Earthlike atmosphere orbiting a sun-like star outside of our solar system, it will remain unanswerable. Next, Charles asks Melodie how she became an astronomer, especially since she'd always planned on being an architect. She even went to MIT to become one, but she missed studying physics, which she realized she truly loved. MIT had just finished constructing their Center for Theoretical Physics, and Melodie shares the story of how she convinced MIT to bend the rules and let switch her major to Physics while continuing to study architecture. When she attended a lecture by a grad student about galaxy clusters, and learned how you could back out the formation history of a cluster of galaxies by looking at the gradients of colors generated by starlight, she realized astronomy was a way to unlock the secrets of the universe. Our next question comes from Alex at North Greene: What are the conditions necessary for life in the universe? It's a question without an easy answer, but the conversation it spawns is worth your time to listen to. It leads Melodie to talk about her love of exploring the natural world and how she co-created a Wilderness Astronomy class. She's also a guide for off-trail, high route backpacking trips where you don't know what's coming next and you need to rely on your instincts, curiosity and bravery as you explore the world, and the universe, around you. If you'd like to know more about what Melodie is up to, she's not on social media but you can check out her website. You've also got an invitation to visit her at the Lowell Observatory for a personal tour! We hope you enjoy this episode of The LIUniverse, and, if you do, please support us on Patreon.

Beginning in the first Trump presidency and expanded under Joe Biden, the US has taken a strategy of technologically containing China through restricting its access to cutting edge semiconductors. As Chinese Whispers has looked at before, these chips form the backbone of rapid advances in AI, telecoms, smartphones, weaponry and more. Washington's aim was clear: to widen the technological gap between the two powers But has this strategy worked? Lately this has become a hot topic of debate as Chinese tech companies such as Huawei and DeepSeek have nevertheless made technical strides. Some even argue that the export controls have spurred on Chinese innovation and self-reliance. In this episode of Chinese Whispers, two very informed and smart guests debate this issue. Ryan Fedasiuk is U.S. Director of The Future Society, an independent nonprofit organization focused on AI governance, and former Advisor for U.S.-China Bilateral Affairs at the US State Department. Steve Hsu is Professor of Theoretical Physics at Michigan State University and a start-up founder. He also hosts the podcast, Manifold. Produced by Cindy Yu and Joe Bedell-Brill.

Raphael Bousso is the Chancellor's Chair in Physics at the Berkeley Center for Theoretical Physics, where he leads the Bousso Group in research on quantum gravity and quantum information. He is a renowned string theorist famous also for his development of the string theoretic landscape and the Bousso bound in holography. In this episode, Robinson and Raphael talk about the foundations of quantum mechanics and whether or not there are any deep mysteries within the theory that remain to be solved, and whether philosophical discussion of these issues is overblown. More particularly, they get into what quantum theories tell us about the world, whether we need different interpretations of quantum mechanics, whether the final theory of the universe will be quantum mechanical, how quantum mechanics connects to cosmology, the multiverse, and quantum gravity, and more.
