Into the Impossible With Brian Keating

For 50 years I taught my students that dark matter surrounds the Milky Way in a giant halo, or that Newton’s laws break down at low accelerations. The Gaia satellite just measured something that makes both of those answers uncomfortable. Subscribe if you want science with evidence, not speculation.

Gaia has measured over a billion stars. What its third data release shows is that the outer rotation curve of our own galaxy appears to decline in a Keplerian fashion. That should not happen if a dark matter halo is doing what we think it does. It also should not happen if MOND is right, because MOND produces flat curves for isolated galaxies. Both camps predicted something flatter. Neither got it.

I walk you through the physics from Kepler to Vera Rubin to Gaia DR3, show you why systematic errors from asymmetric drift, the Large Magellanic Cloud, and the Sagittarius dwarf galaxy matter enormously before anyone draws a conclusion, and lay out the three scenarios that still survive. The most interesting question here is not which side lost. It is why both sides were expecting the wrong curve from our own galaxy.

What you’ll hear:

-Why the neutrino technically counts as dark matter and why that still leaves most of the problem unsolved

-What Kepler’s first law of fatherhood has to do with galactic dynamics

-Why Stacy McGaugh and Mordehai Milgrom might be celebrating too soon

-What Cepheids, stellar streams, and globular clusters could tell us that Gaia cannot

-Whether the Milky Way is too messy to ever give us a clean answer

“The question is not which camp won, but why we were both expecting the wrong curve.” — Brian Keating

Dark Matter Has a Problem. So Does MOND.

Did OpenAI just solve Navier–Stokes—and what would that actually mean for AGI?

Emad Mostaque joins Brian Keating LIVE to examine the claimed breakthrough, what would count as a verified solution, and whether AI solving a major mathematical problem changes the debate about intelligence—or control.

Watch my explainer about AI and the Navier-Stokes problem, including insights from Terry Tao https://youtu.be/je9X59psm6U?si=wGbcLhXmf47jeCHL?sub_confirmation=1 

A convincing answer isn’t necessarily a proof. A mathematical breakthrough isn’t automatically AGI. But if this claim holds up, how much should we update our expectations?

Emad helped bring Stable Diffusion to the world and signed the letter calling for a pause on frontier AI development. In his previous conversation with Brian and AI safety researcher Roman Yampolskiy, he questioned how such a pause could work—and highlighted swarm intelligence as a particularly dangerous and unpredictable risk.

Now we return to the question underneath the excitement: if AI’s capabilities are accelerating, is our ability to understand and control them keeping up?

ON THE TABLE:

• What exactly is being claimed about Navier–Stokes?
• What separates a proposed solution from an accepted mathematical proof?
• If the result holds up, does it demonstrate AGI—or something narrower?
• Can AI produce discoveries that humans struggle to verify?
• What would this change about open-source AI and the argument for a pause?
• Are we watching the wrong risk: a single superintelligence, or swarms of AI agents?
• What evidence would change Emad’s mind?

Bring your questions. We’ll examine the claim, the evidence, and what follows if it’s right.

This livestream discusses a claimed result; it does not assume the Millennium Prize Problem has been resolved.

OpenAI’s Navier–Stokes Claim: Is This What AGI Looks Like? with Emad Mostaque

The man who open-sourced the most-used AI image model in history sat down with the man who has spent a decade proving superintelligence cannot be controlled. Brian set up a debate. What emerged was something more unsettling than any debate.

Roman Yampolskiy is the computer scientist who coined the term AI safety and author of AI: Unexplainable, Unpredictable, Uncontrollable. Emad Mostaque is the co-founder of Stable Diffusion and the only AI CEO who signed the pause letter. He now says he doesn’t know how a pause could work. Yampolskiy thinks that is the only option left.

The question underneath everything is simple: if you have a 50% chance of wiping out civilization and you build it anyway, what are you actually doing? We cover what AI safety researchers actually think the danger is, why nobody has published a paper, filed a patent, or shipped a prototype for controlling a superintelligence, what the Qwen weights being out means for the pause argument, and why Mostaque thinks swarm intelligence is the most dangerous and most unpredictable risk vector we have.

What you’ll hear:
-Why both guests think P(doom) tells you less than you’d hope
-What it means that no company, no lab, and no team has a patent on controlling superintelligence
-Why the models the public receives are slightly lobotomized
-The difference between an AI swarm and the ASI everyone is debating
-Why giving every psychopath access to a cutting-edge intelligence weapon is incoherent safety strategy
-What it would actually take to update Yampolskiy’s assessment

“We either do it, or we die. There is nothing for you to gain by doing it.” — Roman Yampolskiy

Roman Yampolskiy vs Emad Mostaque: I Was The Only Optimist - #569

I joined Peter McCormack to dig into one of the deepest unanswered questions in physics: what is time, and why does it only seem to move in one direction? My answer might surprise you. Time may not be a fundamental feature of reality at all, and understanding space, matter, and energy still doesn't mean we understand the universe itself.

We cover: 

- What may have existed before the Big Bang
- Why something can't truly come from nothing
- How my work with the Simons Observatory could detect gravitational waves from the universe's earliest moments
- What dark matter actually means
- Why even a film as detail-obsessed as Interstellar still gets the physics wrong.

The conversation then turns from cosmic time to human time: mortality, family, meaning, and attention. We get into UFO disclosure, the collapse of institutional trust, and whether AI can ever reproduce the embodied human insight that let Einstein transform physics. My take: AI remains a tool built to serve humanity, and it's time we stop apologizing for humanity's greatness.

The Universe Didn’t Come From Nothing | The Peter McCormack Show

The same mathematics that explains why a fridge magnet sticks to your refrigerator also explains why neural networks work when they have no right to. His group did the calculation. Nobody else had. Subscribe if you want science with evidence, not speculation.

Goldenfeld is a Professor of Physics at UC San Diego, a Fellow of the Royal Society, and a Member of the National Academy of Sciences who spent 36 years at the University of Illinois applying condensed matter physics to problems everyone else had given up on: why the genetic code is optimal, why early life evolved impossibly fast, and why AI works despite being overparameterized beyond anything classical statistics can explain.

The thread connecting all three is one idea: that what emerges from many things together is qualitatively different from the sum of its parts. That idea explains magnetism, AI, the origin of the genetic code, and why life may be inevitable wherever the laws of physics apply. He also argues that what is happening to science right now is not a disagreement about facts but a fracture in how people decide what is true, and that is a more dangerous problem.

What you’ll hear:

-Why the same phase transition that explains magnetism also explains why AI works at all

-Why Francis Crick concluded life must have come from outer space and what Goldenfeld found instead

-What horizontal gene transfer has to do with how libraries work

-Why Goldenfeld thinks Enceladus is a better bet for life than Europa

-The purpose of life, stated as a thermodynamics problem

-Why “different is more” is more useful than “more is different”

“The impact you make is the ratio of what you do divided by what everybody else does. Minimize the denominator.” — Nigel Goldenfeld

CHAPTERS

00:00 AI shouldn't work. It does.

00:56 What is a phase transition?

03:10 What the renormalization group does

08:54 Ising gave up. Wrong dimension.

The Physics Reason AI Works When It Shouldn’t - #568

The system that produces the world’s most important discoveries runs on metrics that nobody agrees on, odds that would stop most people, and mentorship that sometimes looks like cruelty in blue ink. Subscribe if you want science with evidence, not speculation.

Lipomi is Professor and Chair of Chemical and Sustainability Engineering at the University of Rochester and the author of Science Nonfiction: Behind the Scenes in University Research. His lab works on organic electronics, materials science, recyclable polymers, and the science of human touch. He trained under George Whitesides at Harvard, one of the most cited chemists who has never won the Nobel Prize.

The conversation covers the H-index, what elite mentorship actually looks like when your advisor writes “This is illiterate” in blue ink on your outline, and what the future of academic research versus industry careers looks like in an era of AI, demographic headwinds, and graduate school debt that can’t be discharged in bankruptcy. We also get into homochirality, OLED displays, and why Lipomi thinks the nanotechnology revolution already happened, we just didn’t call it that.

What you’ll hear:

-Whether the academic system is designed to produce scientists or to filter them out

-What is Baumol’s cost disease and why it explains rising tuition costs

-Why the nanotechnology revolution already happened and nobody called it that

-How nanotechnology is used in cancer drug delivery today versus what science fiction promised

-What it actually takes to build a PhD career at the intersection of chemistry, mechanics, and neuroscience

-Whether engineering students should be reading Plato — and what countries that skip it are getting right

“Find a skill at the intersection of three or more interests that no one else is working on.” — Darren Lipomi

CHAPTERS

00:00 He says don't go to college. He runs the department.

01:10 The H-index: imperfect, irreplaceable

02:04 1 in 20 PhDs gets the job

08:34 Did life's asymmetry come from space?

12:00 Who is an organic materials chemist at 3am?

13:52 The collaboration that started at a coffee shop

15:22 The nanobot revolution already happened

18:24 Nanotechnology inside your body right now

19:08 The $70 billion invention Kodak gave away

22:12 Kodak, Xerox, Bausch + Lomb: what Rochester built

26:06 Working under Whitesides at Harvard

28:54 What he wrote on the outline in blue ink

30:38 Who you work with matters more than what you work on

31:56 Department chair: hostage negotiator, not boss

34:36 Why the department changed its name after 110 years

36:00 The headwinds have never been stronger

38:44 Should engineers read Plato?

Engineering Chair: Most People Should Not Go To College - #567

John Martinis won the 2025 Nobel Prize in Physics for proving macroscopic quantum tunneling is real. Less than a year later he’s telling why he left Google’s quantum computing team to start over. Subscribe if you want the physics and the politics of building the impossible.

Martinis is the co-founder of Colab and one of the physicists who proved ordinary quantum rules apply to macroscopic systems. He built his career on the same Josephson-junction hardware his Nobel is built on, then led Google’s superconducting-qubit effort, the same team behind Google’s 2019 quantum supremacy claim, before an internal reorg pushed him out.

We go into Anthony Leggett’s challenge to Schrödinger’s cat, what decoherence in quantum mechanics really means, and whether quantum computing is the first technology ever born from pure theory rather than experiment. We also cover the internal Google reorg that pushed Martinis out and what he learned about building something new inside a large institution.

 Whether quantum mechanics applies to the macroscopic world and what it took to prove it

 Why Martinis thinks quantum computing may be the first technology born from pure theory, not experiment

 What negative authority means and why it matters for anyone building something new inside a large institution

 Whether the US can win the quantum computing race against China

 How Martinis thinks about quantum mechanics interpretations after spending a career inside the math

“Always be on the lookout for the impossible, right?” John Martinis

CHAPTERS

00:00 The Nobel call that almost wasn't

01:01 How his wife found out before he did

03:32 Anthony Leggett's challenge to Schrödinger's cat

05:53 Why a Josephson junction, not a quantum dot or trapped ion

07:45 Quantized oscillations: the “smoking gun” and Balmer's ghost

08:18 Measuring the system: the resonance experiment

11:21 Systematic effects: what separates a good scientist from a lucky one

13:42 The Ed Ohm story: the man who found the CMB and doubted it

15:01 Wigner's “unreasonably effective” math and the weirdest thing about QM

16:54 The transistor myth: chewing gum, coat hangers, and germanium

17:34 Microwave engineering meets quantum mechanics

19:26 Decoherence: the friction you can't live without

24:06 The heretical claim: does theory ever precede technology?

28:22 The “paper qubit” problem

29:34 What quantum computers are actually good for

32:27 Should quantum computing be regulated like AI?

33:35 US vs. China: the quantum computing race

35:44 Collapse, Copenhagen, or many worlds? Martinis's answer

37:43 Leaving Google: “essentially demoted”

40:48 Why Colab exists and what “negative authority” means

42:50 The real bottleneck: funding, not physics

John Martinis: The Nobel Physicist Behind Macroscopic Quantum Tunneling - #566

Scott Dodelson spent ten years on the Dark Energy Survey testing the standard model of cosmology. It passed and missed by 2.5 sigma. The Director of Fermilab’s Cosmic Physics Division on why the theory he helped build may be wrong, why nobody can find dark matter, and what it takes to change a scientific consensus. Subscribe if you want science with evidence, not speculation.

Dodelson is Director of the Cosmic Physics Division at Fermilab, Professor of Astronomy and Astrophysics at the University of Chicago, and author of Modern Cosmology, the textbook a generation of cosmologists learned the field from.

Lambda-CDM predicts how the early universe’s tiny fluctuations grew into the structure we see today. The Dark Energy Survey was designed to check that prediction. The answer came back two and a half sigma off. That is both the most precise measurement ever made of how the universe grew, and a crack he cannot stop looking at. His question is not whether the model is close. It is whether close is enough to trust.

We get into the Sigma-8 tension and what it actually takes for a scientific community to change its mind, the Dodelson-Widrow mechanism and his 1994 proposal that sterile neutrinos produced in the early universe could constitute dark matter, and the Neptune vs. Vulcan history of getting dark matter right and wrong. Asked which of those two situations we are in now, Dodelson’s answer is: I have no idea.

What you’ll hear:

Why the April 24, 1992 CMB discovery may have been the only science story ever to lead the New York Times front column

The Dodelson-Widrow mechanism: how ordinary neutrinos in the early universe may have oscillated into the dark matter we see today

Why Brian told Neil deGrasse Tyson to his face that we have already detected dark matter

What it means when a theory can accommodate any result and whether inflation has that problem

Why the particle physics community still does not trust cosmology’s neutrino mass measurements

What cosmology looks like in 2036 if Lambda-CDM breaks

Killing the model is my dream.

0:00 None of it has been found in a lab. How many free passes do we get?

0:44 Dodelson helped build Lambda-CDM. His dream is to kill it.

2:10 10 years. One prediction. Two and a half sigma off.

5:42 "You're in charge" — what mentorship in science actually looks like

6:56 April 24, 1992: cosmology stopped being speculation

9:48 Geoff Burbidge went to his grave a steady-state believer

11:04 What a neutrino is and why it barely interacts with anything

12:36 Brian told Neil deGrasse Tyson we already detected dark matter

18:08 How ordinary neutrinos may have become dark matter

23:24 Lambda-CDM predicts Manhattan's density 13.7 billion years later

26:42 Two and a half sigma: technically a 1% chance the theory is right

28:04 Neptune was dark matter. Vulcan wasn't. Which one are we in now?

31:20 Dark matter, inflation, dark energy: none found in a lab

36:46 If both cracks are the same crack, Lambda-CDM is finished

Fermilab’s Scott Dodelson on Cosmology’s Crisis - #565

Two theoretical physicists helped design landmark surveys of 1,600+ scientists on the deepest unsolved questions in physics — and found almost no consensus at all.

From string theory's shockingly low support to physicists admitting their models run on "belief," this episode exposes the faith hiding inside science.

Adam Frank (University of Rochester astrophysicist and astrobiologist) and Niayesh Afshordi (Perimeter Institute / University of Waterloo cosmologist, co-author of the APS Physics Magazine "Big Mysteries" survey) join Brian to unpack what physicists actually believe versus what they can prove.

We cover: 

- Why string theory pulled a shockingly small share of the vote against loop quantum gravity
- What a Bayesian "prior" reveals about every scientist's hidden beliefs
- Why one branch of physics quietly became unfalsifiable
- How sociology and "tastemakers" can hijack scientific consensus
- Why AI might become the field's unlikely savior.

There is no sane statistical analysis that doesn't have a prior — that's your belief.

Faith & the Physicist: Aliens, Astrobiology, String Theory, and the Search for Meaning

Annie Jacobsen on BIOLOGICAL WAR: how a single lab leak could take us from outbreak to anarchy in six days — and why bio may be scarier than nuclear.

WIN a signed copy of BIOLOGICAL WAR or NUCLEAR WAR, a meteorite & more — enter free: https://briankeating.com/annie

(Join there for the free Biological War Scenario Simulation and Source Dossier + early access to my next Nobel-laureate interview.)

Covid killed ~1% of the people it infected. Pneumonic plague, untreated, kills nearly 100% within 24 hours. In her new book Biological War: A Scenario, bestselling journalist Annie Jacobsen war-games what happens when an engineered pathogen escapes — drawing on interviews with presidential advisors, secretaries of defense, STRATCOM commanders, epidemiologists, and directors of Operation Warp Speed.

We get into gain-of-function, the Soviet bioweapons program, mirror life, AI and bioweapons (including her conversation with Sam Altman), the Fermi Paradox and the Great Filter — and why the first 24 hours decide everything.

Annie Jacobsen: How One Lab Leak Ends the World in 6 Days - #564

Why are men's sex drives so strong? Can genetic information be destroyed? And why does the desert lizard have such intricate patterns? 

I had the extraordinary privilege of exploring these topics with Richard Dawkins, one of the world’s most influential and thought-provoking scientists!

Dawkins is a renowned evolutionary biologist, zoologist, and author. He is also a prominent figure in New Atheism alongside Sam Harris, Daniel Dennett, and Christopher Hitchens and is well known for his criticisms of creationism and intelligent design. 

In our wide-ranging conversation, we explored the evolution of sex drive and aesthetic appreciation, genetics, the intersection of theoretical and experimental science, the potential of artificial intelligence, and more.
