The Origins Podcast with Lawrence Krauss

• Fruitful Disagreement in an Age of Division with Robert George and Cornel WestRobert George and Cornel West

  One of the great pleasures of hosting the Origins Podcast is talking with fascinating thinkers who challenge my perspectives and with whom I can have frank, if provocative, discussions. My recent conversation with Robert George and Cornel West was particularly enjoyable. These two distinguished intellectuals embody the spirit of respectful and meaningful dialogue that the Origins Project Foundation aims to foster. Robert George is a renowned conservative legal scholar and Catholic professor at Princeton University, while Cornel West is a leading progressive philosopher and Protestant scholar at Union Theological Seminary, and an academic celebrity. Together, they've authored a timely new book, Truth Matters, exploring how fruitful dialogue can bridge ideological divides even during polarized times.In our conversation, we tackled subjects including philosophy, theology, politics, and the crucial role respectful disagreement plays in uncovering deeper truths. Joining the discussion as a scientist, atheist, and someone raised in a Jewish tradition, I brought a viewpoint to our exchange that differed from those of both Robert and Cornell, who in spite of their political differences are both Christians, and scholars in the humanities . It was especially rewarding to find common ground with Robert and Cornel despite our differing starting points. All told, I found it one of the most fascinating discussions to date, and the first with more than one person. It worked. :)This kind of rich and thoughtful engagement is precisely what inspired me to start the Origins Podcast. Robert George and Cornel West remind us that disagreements are valuable, as they help us move closer to understanding not only each other, but also ourselves.As always, an ad-free video version of this podcast is also available to paid Critical Mass subscribers.

• What's New in Science With Sabine and Lawrence

  I’m excited to announce the fourth episode of our new series, What’s New in Science, co-hosted by Sabine Hossenfelder. Once again, Sabine and I each brought a few recent science stories to the table, and we took turns introducing them before diving into thoughtful discussions. It’s a format that continues to spark engaging exchanges, and based on the feedback we’ve received, it’s resonating well with listeners.It was a bit of a slow month for science news, but we did find six stories worth examining, including what sounds like a preposterous claim, turning rain into electricity! It turns out it doesn’t violate any laws of physics, but is not likely to address our energy needs. The Hype of the Month award goes to the claim of biosignatures on planet K2-18, which got worldwide coverage, even though experts were pretty certain it was wrong from the get go, and subsequent analysis finds no such evidence. A claim that gravity is just a computation is examined, and dismissed, while evidence for exotic antimatter nuclei at CERN is sound science, even if it is not earth shattering. It reminds us that exotic physics must be considered in exotic locations like the early big bang, or the cores of neutron stars. Sabine was excited about a new result regarding laser fusion, even if it is more likely to be useful for weapons production than commercial energy production, and this time, I was the one to bring up a new result in Quantum Computing, this time using ‘qu-quints’ to simulate an actual physics system, although a simple one in two dimensions. It was another lively and thoughtful exchange, and I hope you’ll enjoy it as much as we did.As always, an ad-free video version of this podcast is also available to paid Critical Mass subscribers.

• Neil Shubin: Science, Exploration, Patience, and Survival at the Ends of the Earth

  One of the best parts of hosting the Origins podcast is talking with remarkable scientists whose ideas have changed the way we understand ourselves and our world. My recent conversation with Neil Shubin was particularly enjoyable, not only because Neil is a friend whose insights I admire, but because our dialogue ranged across some of the most fascinating questions at the intersection of evolution, exploration, and human curiosity.Neil became widely known for discovering Tiktaalik, the fossil fish whose fins contain bones remarkably similar to the limbs of land animals, including us. He is currently the Robert R. Bensley Distinguished Service Professor of Organismal Biology and Anatomy at the University of Chicago and the bestselling author of Your Inner Fish and, most recently, The Ends of the Earth. But beyond his credentials, Neil embodies the careful, patient, and humble approach to discovery that value in science.Our discussion began with the unexpected paths scientists take, including Neil's own formative experiences. He described how museum visits and planetarium shows ignited his childhood fascination, and we talked about how a single course on vertebrate evolution at Harvard redirected his career from veterinary medicine to fossil hunting. Neil recounted, and we discussed at length, the meticulous thought and considerable risk that led him and his colleague, Ted Daeschler, to choose the Canadian Arctic for their famous expedition. It took six summers of tough fieldwork before their gamble yielded Tiktaalik, transforming our understanding of how life transitioned from water to land.But our conversation wasn't just about past discoveries. Neil and I explored broader themes about the nature of science itself: how hypotheses are formed, the patience and courage it takes to test bold ideas, and the critical importance of embracing failure. We agreed that stepping outside one's comfort zone is almost always necessary to achieve scientific breakthroughs, and Neil shared how his own career exemplifies precisely that.This kind of deeper dialogue, going beyond the headlines to explore the very human stories behind scientific discoveries, is one of the reasons I started the Origins podcast. I hope you find this conversation with Neil Shubin as enjoyable and thought-provoking as I did.As always, an ad-free video version of this podcast is also available to paid Critical Mass subscribers.

• Stephanie Canizales on the human tragedy of undocumented and unaccompanied migrant youth in the US.

  Six months or so ago, I had a fascinating interview/discussion with Stephanie Canizales about her book, Sin Padres, Ni Papeles, which described her five year PhD project interviewing young people who had migrated from Central America as undocumented and unaccompanied minors in pursuit of a better future. These children were sent by their parents because they had no other choice, either to protect their lives from violence or because they had no means to support them at home. Once these children arrived in the US they were met by either impoverished relatives who often couldn’t support them. With no access to education or any legal means of supporting themselves they were forced to take low-wage jobs just to survive. I believe our society should be judged not by how well we keep people out, but how well we treat people when they are here. The story of these children is heart wrenching, and raises many complex issues, which may challenge previous notions you may have about such things as child welfare laws, about how we treat these young people who were driven here not out of choice, but through necessity, and who our society largely abandons once they arrive. Because of the vicissitudes of international affairs and other unexpected factors, we were not able to release this dialogue before now. But perhaps there could be no more opportune time to address this issue. Kilmar Armando Abrego Garcia came to this country as a 16 year old, a minor sent by his family to protect him from local gangs. In the intervening 14 years in the United States he was never charged or convicted of a crime, just as he had never been so charged or convicted in his home country of El Salvador. He had a job, and had several children with his US citizen wife. Nevertheless, he was recently illegally deported, without any trial, back to a maximum security prison in El Salvador, leading to a vigorous public debate. During the public discussions, Kilmar, and other illegal immigrants have been vilified for the acts of desperation that led them to enter the US illegally. But very little has been discussed about the harrowing challenges people like Kilmar met when they arrived here, alone, as children. My discussion with Stephanie will hopefully add a new dimension to the current public debate on this issue, focusing on real people rather than statistics, and on both the causes for the recent illegal migration to the US, and also the actual impact both on the country and on the immigrants while they live in the US. In so doing, I hope this expands your perspective of this complex problem, which is, after all, one of the purposes of this podcast, and of the Origins Project Foundation.As always, an ad-free video version of this podcast is also available to paid Critical Mass subscribers.

• What's New in Science With Sabine and Lawrence

  I’m excited to announce the third episode of our new series, What’s New in Science, co-hosted by Sabine Hossenfelder. Once again, Sabine and I each brought a few recent science stories to the table, and we took turns introducing them before diving into thoughtful discussions. It’s a format that continues to spark engaging exchanges, and based on the feedback we’ve received, it’s resonating well with listeners.This time, we covered a wide range of intriguing topics. We began with the latest buzz from the Dark Energy Spectroscopic Instrument suggesting that dark energy might be changing over time. I remain skeptical, but the possibility alone is worth a closer look. We followed that with results from the Euclid space telescope, which has already identified nearly 500 strong gravitational lensing candidates—an impressive yield from just the early data.We also returned to quantum computing, comparing the hype around Microsoft’s recent claims to Amazon’s quieter but arguably more meaningful development—a chip with built-in error correction, which could mark real progress toward scalable systems. From there we went to Earth, where a team at Princeton reported a result that almost sounds like a perpetual motion machine: using the Earth’s magnetic field to generate electric current. It’s not going to power the grid, but it raises fascinating questions.And of course, we couldn’t resist discussing a new round of exotic claims about hidden structures beneath the Pyramids of Giza, before wrapping up with a reanalysis of decade-old data from the Curiosity rover on Mars. It suggests the presence of organic compounds that might hint at life—but as always, the story is more complicated.It was another lively and thoughtful exchange, and I hope you’ll enjoy it as much as we did.As always, an ad-free video version of this podcast is also available to paid Critical Mass subscribers.
