  • Did She Just Prove the Multiverse Is Real? (Ft Laura M-Houghton) [Ep. 501]

    Did She Just Prove the Multiverse Is Real? (Ft Laura M-Houghton) [Ep. 501]
    Jul 9 2025
    What if the Big Bang wasn’t the beginning? What if our universe is just one in a vast cosmic ocean of universes, and we have the evidence to prove it? In this episode of Into the Impossible, I’m joined by theoretical physicist Laura Mersini-Houghton to explore one of the most provocative ideas in modern cosmology: the multiverse is not only real—it’s testable. Mersini, author of Before the Big Bang, walks us through her bold predictions about the structure of the cosmos, including the mysterious cold spot in the cosmic microwave background (CMB) that she foresaw years before it was confirmed by the Planck satellite. Together, we dissect her groundbreaking theory that our universe began as one branch of a quantum wave function stretching across a multiverse landscape. We talk quantum decoherence, cosmic scars, and how entanglement with other universes could leave measurable fingerprints in our sky. We also debate criticisms from fellow physicists and dive into what these revelations mean for the future of dark energy and cosmological theory. — Key Takeaways: 00:00 What happened before the Big Bang? 01:56 The CMB cold spot prediction 05:16 Quantum entanglement and decoherence 11:31 Criticism and evidence for the multiverse 17:06 The wave function of the universe 20:48 The string landscape and constants of nature 23:54 The cold spot and the hemispherical anomaly 37:20 Thoughts on the recent DESI suggestions 40:46 Judging a book by its cover 47:31 The multiverse and religion 57:29 Outro — Additional resources: ➡️ 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.

  • Timescapes Make Dark Energy Irrelevant! (ft. David Wiltshire) [Ep. 500]

    Timescapes Make Dark Energy Irrelevant! (ft. David Wiltshire) [Ep. 500]
    Jun 30 2025
    What if everything we know about the universe’s expansion is wrong? David Wiltshire offers a radical perspective on cosmic acceleration and dark energy, proposing that both might be illusions created by the varying passage of time in different regions of the universe. Wiltshire challenges the foundations of modern cosmology with his innovative Timescape model. We discuss the foundations of Einstein's theory of relativity, examining how time behaves differently in regions of high and low matter density. Wiltshire explains how this could alter our understanding of the universe’s expansion, potentially eliminating the need for dark energy altogether. His work revisits Mark’s Principle and its influence on cosmology, offering an alternative explanation for cosmic phenomena. This episode will captivate anyone interested in the future of cosmological theory, the mystery of dark energy, and the complex nature of time. Don’t miss out! — Key Takeaways: 00:00:00 Intro 00:01:36 David Wiltshire’s model and its implications 00:02:35 Mach's Principle and its influence on relativity 00:06:28 Gravitational time dilation and its implications 00:42:16 The cosmological equivalence principle 00:42:50 The Timescape Model and its predictions 00:43:53 The role of dark energy and the cosmological constant 00:53:43 The philosophical and psychological implications of Timescape 01:09:41 Outro — Additional resources: ➡️ 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.

    Please join my mailing list here 👉 https://briankeating.com/list to win a meteorite 💥 This episode, hosted by Brian Keating—Chancellor’s Distinguished Professor of Physics at UC San Diego—delves into one of the most fascinating and underappreciated stories at the intersection of beauty, brilliance, and invention. Today, we step away from pure physics and astronomy to explore the remarkable life of Hedy Lamarr, an iconic Hollywood actress whose real genius lay not just on the silver screen, but at the heart of technological innovation. Listen in as Brian Keating brings to life the legacy of a woman who changed the world—not for fame, but for the sheer joy of invention and enduring curiosity. - Key Takeaways: 00:00 Hedy Lamarr: Star and Inventor 03:30 Dual Facade: Performance and Analysis 09:04 Espionage and Escape Plan 10:35 Hedy Lamarr's Hollywood Transformation 13:59 Frequency Hopping Communication Technique 16:35 Hedy Lamarr's Overlooked Invention 22:43 Genius: Curiosity Over Credentials 24:01 "Hedy Lamarr: Beyond Hollywood" - The Scientists is a documentary-style podcast series hosted by astrophysicist Brian Keating. Each episode explores the untold stories behind history’s greatest minds—from Nobel laureates to visionary misfits—revealing the personal struggles, intellectual triumphs, and paradigm-shifting ideas that changed the world. Each week, I dive into the life and legacy of a legendary scientist—experimentalists, theorists, and observers alike—and uncover insights you can apply to your own work and worldview. Science didn’t appear fully formed; it was built by real people solving real problems under pressure. Their ideas still shape our future. We’ll examine not just what they discovered, but who they were—from their obsessions and honors to their most spectacular ideas, brilliant blunders, and beautifully human flaws. New episodes weekly.

Greatest guests, Great topics. Thoughtful discussions with guests at the top of their fields. For listeners who crave pioneering into subjects that extend to the edges of what humanity knows, this is the podcast for you. Thanks Brian!

Great Guests, great topics

I've just started listening to Brian Keating's podcasts and I know I'm going to binge them. So entertaining, and so thought provoking, and so clear. I hesitated to listen to the September 6 with Steven Koonin since I thought, no way am I going to spend time with a climate change denier. I'm glad I trusted Brian though and gave him a chance. The podcast may not have changed my mind but the time spent hearing the science, the statistical model, and Brian's careful and respectful presentation was a total pleasure. Very highly recommended!

Great Podcast!

Even if you're not an expert of the cosmos (like me) this podcast is very easy to digest and super interesting. The big question of "How did the universe begin?" is not an easy one to answer, but it's a super cool topic to dive into. Dr. Keating takes you on a journey with other scientists to tackle this question and other intriguing phenomena throughout time and space. I love these deep dives and even if we never really find out how it all began I'll keep going into the impossible to learn more about our universe.

Highly recommend!

I have been binging this podcast recently, here and on other platforms. There have been many great episodes but the ones with Shep Doeleman, Heino falcke, Rai Weiss and Barry Barish really resonated with me for both the depth of the technical discussion, passion and interest from both the guests and Dr. Kearting, and the unguarded nature with which they answered the more personal questions.

Going through the history of the podcasts, I think Dr. Keating has grown as an interviewer becoming stronger in the follow-up to guest responses and striking a good balance in the science topics explored. Not to say early episodes were weak. For me, the content of the episodes and passion of the discussions are the main appeal, and those stood out for their excellence right from the beginning.

I would like to thank Dr. Keating for putting these out there. I hope you are able to continue for as long as people keep doing science,

Fascinating and often inspiring

If your goal is to comprehend the universe on a larger scale or explore the properties of celestial bodies. These podcasts will help you in your goal.

Dr. Keating’s personal insights on a wide range of topics, coupled with such highly respected guest are manna for the mind.

From the beginning of my goal to learn about how this wonderful universe works or at least as an observer trying to understand how I believe it might work through my lens jump started by reading Wrinkles In Time by Smoot and Davidson. Then years later finding myself bored with yet another rendition of the double slit experiment I searched for podcasts by physicist near me. Finding the Into the Impossible podcast has never once been disappointing. As a fellow San Diegan I am thrilled with the likelihood that I’ll be lucky enough someday to meet Dr. Keating in person.

My brain is conducting information very slowly indeed, but I enjoyed the superconducting podcast! (The robot-inserted commercial interruptions are confusing, though. Maybe Audible can make its software as smart as the people interviewed on this podcast.)
