About this listen

 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.
