Is the universe intrinsically random? In this conversation, we dive deep into why the universe may be fundamentally, intrinsically random. Whether inflation on life support, the truth behind the Hubble tension, and whether cosmology is approaching the event horizon, limits beyond which humans can never know. Today we're joined by one of the architects of modern cosmological inference, Professor Andrew Jaffee, author of a new book called The Random Universe that argues that every observation in science is shaped by the models we bring to it, biases and all.

KEY TAKEAWAYS

00:00–01:13 — Science and life rely on building models.

01:13–03:35 — Models of people and reality are often wrong and revised.

04:04–06:01 — Observation depends on prior theories.

06:01–07:32 — Models can’t be escaped, only improved.

07:32–08:57 — No single scientific method exists.

08:57–11:25 — Science uses induction, not pure proof.

11:25–13:22 — Induction isn’t certain, only probabilistic.

13:22–15:36 — Induction works because nature is regular.

17:44–19:08 — Big Bang emerges from well-tested models.

19:08–21:15 — Current cosmology is stressed, not broken.

29:19–30:36 — Probability gives meaning to models.

39:45–41:11 — Randomness often reflects limited knowledge.

43:46–45:00 — Quantum physics is fundamentally probabilistic.

49:09–50:04 — Inflation awaits decisive observational tests.

Can AI help us solve the hardest problems in Mathematics? Terry Tao - #535 Dec 30, 2025

Will AI solve future math proofs?

Every time you type a password, buy something online, or send an encrypted message, you’re trusting an assumption about prime numbers: that they don’t hide an exploitable pattern. Modern cryptography depends on primes behaving “randomly enough,” yet many fundamental questions about primes remain unproven.

In this episode, I’m joined by Fields Medalist Terence Tao to explore what mathematicians can prove, what they strongly suspect, and what could change if unexpected structure appeared in the primes. We discuss pseudorandomness and why it matters for encryption, the twin prime conjecture, and how quantum computing reshapes what is feasible in computation and security.

We also get into AI and mathematics: why large language models can sound convincing even when unreliable, how AI can help with idea generation and literature recall, and why verification and proof assistants will matter if AI is to contribute to real mathematical progress. Along the way, Tao explains proof techniques like proof by contradiction, why complex numbers and the square root of minus one are so central, and how high-dimensional geometry breaks low-dimensional intuition.

Finally, Tao shares a real-world example of how math breakthroughs translate into technology: compressed sensing, which has enabled much faster MRI scans by reconstructing images from far less data.

Physicists Missed These Particle Tracks for Decades (ft. Daniel Whiteson) Dec 26, 2025

Show notes

Please join my mailing list here 👉 https://briankeating.com/yt to win a meteorite 💥

From the electrifying environment of high-speed particle collisions to the challenge of sifting signals from heaps of experimental noise, you'll hear how Prof Whiteson and his team are pushing boundaries. They discuss bold new algorithms capable of spotting non-standard tracks—think wild trajectories that defy classical expectations and could reveal surprises nature has kept hidden. Practical questions about detector design, efficiency, and even the mathematics of “smooth” particle paths make for a rich, dynamic dialogue.

If you’re curious about how physicists ask the universe its most challenging questions, the frustrations and breakthroughs of innovation, and the fascinating interplay between theory and experiment, this episode will take you to the front lines of discovery. Plus, hear how machine learning might help us find not just the next weird particle, but perhaps the next Nobel-worthy revelation. Get ready for a fascinating journey into the impossible!

Daniel Whiteson is a physicist whose research spans a wide range of topics at UC Irvine. By day, he works on the ATLAS experiment, one of the major physics collaborations at the Large Hadron Collider, where he contributes to Higgs boson precision measurements and develops advanced techniques in machine learning, data acquisition, and trigger systems. His research group is known for applying machine learning innovations to physics problems, including projects beyond ATLAS—like using approximate symmetries or jet pattern matching. Recently, his team has been focused on machine learning projects to identify unusual particle tracks, always pushing the frontier between physics and data science.

What Is 3I/ATLAS? Avi Loeb - #534 Dec 23, 2025

Show notes

Please join my mailing list to get FREE notes and resources from this show, plus your chance to win a real meteorite: http://briankeating.com/yt

Join us LIVE with Harvard astrophysicist Avi Loeb for the final verdict on the interstellar object 3I/ATLAS, the third confirmed visitor from beyond our solar system. We examine the newly proposed 14th anomaly: the remarkably rare alignment of 3I/ATLAS’s rotation axis within about 8 degrees of the sunward direction at distances greater than 5 AU, a configuration with a probability of less than about 0.5 percent if random.

This alignment has major implications for how we interpret the object’s anti-tail jet geometry, rotational dynamics, and overall physical behavior, adding to a growing list of anomalies that strain standard cometary explanations. Whether you are interested in jets, rotation periods, anti-tail physics, or what these observations imply about natural versus technological origins, this livestream offers a rigorous, evidence-driven deep dive. We will lay out the data, compare competing interpretations, and ask the central question: is 3I/ATLAS simply an unusual comet, or something fundamentally different?

Did You Know This Genius Changed Physics Forever? Dec 22, 2025

Pilgrimage mode: kilt on, chapeau secured, and I’m standing outside 14 India Street, Edinburgh — the birthplace of the physicist I’d nominate as the quiet GOAT: James Clerk Maxwell.

In this solo vlog, I walk the neighbourhood where Maxwell grew up, try (and fail) to get into the small museum without a reservation, and connect the dots from Maxwell’s equations to the modern world: Wi-Fi, GPS, power grids, and yes… a Tesla charging across the street from his childhood home.
