Into the Impossible With Brian Keating

• Are We Wrong About the Big Bang? Niayesh Afshordi

  Get Dr. Brian Keating’s NEW Book for Only 0.99! This week only: https://www.amazon.com/dp/B0FN8DH6SX?ref_=pe_93986420_775043100 For over a century, cosmologists have believed that the universe began a single fiery moment. The Big Bang. But what if that story is incomplete? Or what if it's even wrong? My guest today, Professor Niayesh Afshordi, is a professor of astrophysics at the Perimeter Institute and the University of Waterloo. He and his colleague Bill Halpern argue that the real battle in science is over the mysteries of singularities, those points where our equations collapse and space, time and physics itself seem to break down. In a new book, Battle of the Big Bang, they take us inside the fight to understand whether the Big Bang was truly the beginning of it all, or whether it was just one chapter in a far stranger cosmic saga. KEY TAKEAWAYS 00:00:00 – Cosmologists no longer see the Big Bang as the beginning of time 00:11:01 – Singularity vs the later hot Big Bang phases like nucleosynthesis 00:12:13 – Survey of physicists shows “Big Bang” is understood differently 00:15:37 – Hawking and singularities 00:23:12 – Black hole information paradox remains unresolved after 50 years 00:30:26 – Religion remains a social tool 00:35:56 – The Simons Observatory was created to probe primordial gravitational waves in the CMB 00:39:50 – Scientific careers are constrained by funding and “hot topics” in research 00:41:17 – Science advances by tying ideas to observation, not just social structures 00:42:07 – Disagreement with Carlo Rovelli 00:44:54 – Competing quantum gravity models are ideas, not fully testable theories yet 00:46:14 – String theory, loop quantum gravity, and holography lack experimental evidence 00:47:55 – Cancellation of CMB Stage-4 highlights limits of experimental cosmology 00:49:14 – Afshordi views himself closer to an observer than a pure theorist 00:54:51 – Scientific progress benefits from bridging between communities 00:57:47 – Repulsive gravity in inflation avoids singularities but leaves open loopholes 01:01:00 – Singularity theorems can break down with quantum gravity or altered dimensions 01:03:05 – Our universe was born inside a black hole 01:06:16 – Future probes might let us see further back than the CMB 01:10:56 – Einstein unknowingly started the quest for quantum gravity - Additional resources: Get Niayesh Afshordi’s book: https://www.amazon.com/Battle-Big-Bang-Cosmic-Origins/dp/0226830470 Get Dr. Brian Keating’s NEW Book for Only 0.99!

• The Matrix Is a Documentary: Riz Virk on the Simulation Hypothesis

  Get my new book Focus Like a Nobel Prize Winner for just 99 cents while the sale lasts: https://a.co/d/hi50U9U Please join my mailing list here 👉 https://briankeating.com/list to win a meteorite 💥 What if your life wasn’t real—not metaphorically, but literally? That’s the premise my guest today has been exploring for years. Rizwan Virk, MIT graduate, gaming entrepreneur, and author of The Simulation Hypothesis, believes that physics, computing, and even ancient wisdom traditions point to the same unsettling conclusion: we may be living inside a programmed reality. In this conversation, we dive into the science, philosophy, and technical roadmaps that could one day prove—or disprove—this theory. We explore quantum mechanics, AI, and the limits of spacetime itself, asking whether reality is an unshakable foundation… or just a beautifully rendered illusion. Key Takeaways:  00:00 Intro  00:00:42 The Simulation Hypothesis  00:10:14 The limitations of AGI 00:15:17 Rizwan’s religious background 00:21:43 Energetic physical limitations in a simulation 00:28:33 Quantum computing and the simulation hypothesis 00:34:45 Judging a book by its cover 00:37:11 The Planck length  00:41:59 Is Deja Vu a consequence of the simulation?  00:43:41 Ethical and moral considerations 00:48:35 How to avoid collapsing the wave function  00:54:33 Cracks in the matrix  01:02:21 What’s the purpose of the simulation?  01:07:28 Rizwan’s next project  01:09:02 The winning strategy  01:10:37 Outro — Additional resources:  ➡️ Follow Rizwan Virk: ✖️ Twitter: https://x.com/rizstanford?lang=en  ➡️ Follow me on your fav platforms: ✖️ Twitter: https://twitter.com/DrBrianKeating  🔔 YouTube: https://www.youtube.com/DrBrianKeating?sub_confirmation=1  📝 Join my mailing list: https://briankeating.com/list  ✍️ Check out my blog: https://briankeating.com/cosmic-musings/  🎙️ Follow my podcast: https://briankeating.com/podcast  — Into the Impossible with Brian Keating is a podcast dedicated to all those who want to explore the universe within and beyond the known.

• The Man Who Named the Big Bang… and Hated It! Fred Hoyle

  Buy my new book Focus Like a Nobel Prize Winner for just 99 cents for a limited time only https://a.co/d/hi50U9U Join my mailing list here 👉 https://briankeating.com/yt to win a meteorite 💥 Fred Hoyle coined the term “Big Bang”—but he hated the theory it described. Instead, he championed the steady state universe, helped uncover the stellar origin of the elements, and gave us the immortal phrase: “We are stardust.” This video explores Hoyle’s brilliance and contradictions: Why he mocked the Big Bang yet proved it correct How he predicted the “Hoyle state” that makes carbon—and life—possible His role in the legendary B²FH paper that rewrote cosmic history The injustices that kept him from a Nobel Prize His radical speculations on panspermia, Stonehenge, and cosmic design Hoyle’s story is a masterclass in scientific courage: following data even when it destroys your own theory. 👉 Subscribe for more deep dives into the rebels who reshaped science: Into the Impossible Podcast - Key Takeaways: 00:00 Fred Hoyle: Defying Scientific Norms 06:02 "Fred Hoyle: Unconventional Scientific Curiosity" 10:11 Hoyle and Littleton's Cosmic Inquiry 12:32 Constructive Contrarianism in Cosmology 14:59 Science Communication and Public Responsibility 19:09 B2FH: Stellar Element Synthesis 21:02 Hoyle's Interdisciplinary Genius 25:53 Universe's Surprising Insights 27:46 Nobel Prize Debate: CMB Origins 32:14 "Helium Mystery and Hoyle's Concession" 35:07 Hoyle's Overlooked Nobel Stance 38:23 Hoyle's Unyielding Scientific Pursuits 42:36 Fred Hoyle: Science's Intellectual Rebel - Join this channel to get access to perks like monthly Office Hours: https://www.youtube.com/channel/UCmXH_moPhfkqCk6S3b9RWuw/join 📚 Get a copy of my books: Think Like a Nobel Prize Winner, with life changing interviews with 9 Nobel Prizewinners: https://a.co/d/03ezQFu My tell-all cosmic memoir Losing the Nobel Prize: http://amzn.to/2sa5UpA The first-ever audiobook from Galileo: Dialogue Concerning the Two Chief World Systems: Ptolemaic and Copernican https://a.co/d/iZPi9Un Follow me to ask questions of my guests: 🏄‍♂️ Twitter: https://twitter.com/DrBrianKeating 🔔 Subscribe https://www.youtube.com/DrBrianKeating?sub_confirmation=1 📝 Join my mailing list; just click here http://briankeating.com/list ✍️ Detailed Blog posts here: https://briankeating.com/blog 🎙️ Listen on audio-only platforms: https://briankeating.com/podcast #universe #podcast #briankeating #intotheimpossible #science #astronomy #cosmology #cosmicmicrowavebackground #intotheimpossible #briankeating Learn more about your ad choices.

• Is 3I/ATLAS Alien Technolgy? Avi Loeb & MIchael Shermer DEBATE

  Get my My new book, Focus Like a Nobel Prize Winner -- https://a.co/d/hi50U9U It's just 99¢ on Kindle for launch week ONLY. It’s the perfect companion to this conversation—lessons in thinking clearly, staying curious, and pushing past conventional wisdom from my conversations with 22 Nobel Prize winners! Brian Keating sits down with Harvard astrophysicist Avi Loeb and renowned skeptic Michael Shermer to dissect the latest enigma sweeping through our solar system—3I/ATLAS. • What makes 3I/ATLAS extraordinary? • It’s the third confirmed interstellar object to visit our solar system—after ʻOumuamua and Borisov—racing through space at hyperbolic speeds and exhibiting an orbit intriguingly aligned with our ecliptic plane • Observations by Hubble and James Webb reveal a coma dominated by carbon dioxide, with traces of water, carbon monoxide, nickel, and cyanide—an unusual chemical signature even among comets. • Avi Loeb’s provocative hypothesis: He and collaborators propose that 3I/ATLAS might not be natural at all—but potentially a piece of alien technology, given its improbable trajectory, ecliptic alignment, and close approach to Mars and other planets—arguably orchestrated rather than accidental. • Michael Shermer pushes back: A constructive skeptic’s view on whether the evidence truly supports Loeb’s scenario, grounding the discussion with a critical evaluation of observational data versus speculative inference. Don’t miss this rare convergence of cutting-edge astrophysics and disciplined skepticism—because how we interpret 3I/ATLAS could redefine our understanding of interstellar visitors.
