In this episode, I sit down with Harvard astrophysicist Avi Loeb to explore his provocative new article analyzing the interstellar object 3I/ATLAS — a visitor from beyond our solar system that might not be natural.

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 o

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.

In this exclusive interview, Professor Mario Jurić reveals how the Vera Rubin Observatory accidentally discovered 2,000 asteroids in just 10 hours while testing its capabilities on the distant Virgo Cluster—transforming humanity's asteroid discovery rate from 20,000 per year globally to potentially over one million annually with a single telescope. Jurić explains how VRO's revolutionary multi-messenger astronomy capabilities will detect dark matter's effects and light simultaneously, automatically slewing to capture cosmic catastrophes like black hole collisions within 30 seconds of detection. From mapping dark matter in galaxy clusters 54 million light-years away to building Earth's first comprehensive planetary defense system against asteroid impacts, this conversation explores how one observatory is about to fundamentally change both our understanding of the universe and our ability to survive in it. — Please join my mailing list here

Is everything we thought we knew about the universe… wrong? Is the Lambda-CDM model nearing its breaking point? Could dark energy actually be evolving? In this episode of Into the Impossible, I’m joined by Kyle Dawson and Daniel Green to discuss the latest data from the DESI experiment. These new results are making headlines, and rightfully so, as they hold the potential to transform our understanding of the universe completely.  Kyle Dawson, a key figure in the DESI project and professor at the University of Utah, explains the findings from DESI’s second data release. Together with Daniel Green from the University of California, San Diego, we dig into how fresh observations of dark energy, baryon acoustic oscillations (BAO), and cosmic expansion are revealing cracks in the standard model. We also break down the implications of these results and talk about the possible existence of negative neutrino masses—a topic that’s been gaining a lot of attention in the cosmology community.

How are recent DESI experimental results challenging the traditional view of dark energy as a fixed cosmological constant? Are foundational assumptions in Einstein’s general relativity limiting progress in theoretical physics? And how do tensions in cosmological measurements, like the Hubble constant discrepancy, reflect deeper issues in physics? In this episode, we’ll explore these fundamental questions with none other than Eric Weinstein! Eric is one of the most revered thinkers of our generation. Though not an academic physicist, he proposed a unified theory of physics in 2013, which is supposed to have the potential to explain phenomena that string theory cannot. In a lecture held live at UCSD in April 2025 at the prestigious Astrophysics and Cosmology Seminar, Eric presented an update to his groundbreaking theory. Today, we’ll discuss his fascinating theory, the future of physics and academia, and much more.  Eric is an investor, financial executive, and host of The Portal. He and his brother, Bret Wei

In a world increasingly shaped by science and technology, how do we determine what constitutes truth? What role does society play in shaping scientific knowledge consensus? And what are the implications for the future of research and innovation?  In this episode, I sit down with Steve Fuller, a renowned sociologist of science from the University of Warwick in the UK, for a thought-provoking conversation. Steve and I explore the deep connections between science and sociology, discussing how science can learn from sociology and vice versa. Steve challenges conventional wisdom and invites us to critically examine the complex interplay between science, society, and the pursuit of knowledge.  With a passion for exploring the philosophical underpinnings of science, he shares his insights on social epistemology, the philosophy of science, and the evolving role science should play in society, especially in an increasingly polarized world. —
