The Origins Podcast with Lawrence Krauss

• Announcing our new 12-part series: A dozen Lessons on Physics and Reality

  I am thrilled to introduce a significant new segment for the Origins Podcast. We are producing a fully fledged 12-part series titled “A Dozen Lessons on Physics and Reality.” Over the coming months, we will release these lectures to provide a comprehensive guide to how physicists think about the world. I’m particularly excited to share the wonder and insights that are often lost in standard textbook descriptions, while giving more detail than one might obtain in a standard 1 hour physics lecture. These will be based on lectures I have given to non-scientists at institutions I have taught, ranging from Yale University to The New College of Humanities in London.We begin with Lecture 1: A Tour of the Universe.To understand the cosmos, we must abandon the linear scales of human experience. In this opening lecture, I utilize the mathematical tool of “powers of ten” to map the true playing field of physics. This tour is about perspective. It reveals how the universe operates on scales of space and time that are vastly different from our daily lives, ranging from the subatomic scales to the cosmic microwave background. It is a journey that highlights our cosmic insignificance while simultaneously celebrating the power of science to explore our origins and to change our perspective of our place in the cosmos. This tour is just the beginning. Here is the full curriculum we have planned for the series:* A tour of the Universe* The Gestalt of Physics: Tools for seeing* Space, Scale, and Symmetry* Motion, from Galileo to Einstein* Gravity, Dark Matter, and the Expanding Universe* Electricity and Magnetism, a repeat performance* The Four Forces of Nature* Quantum Mechanics 1* Quantum Mechanics 2: Chemistry* Quantum Mechanics in your face* Heat worth dying for?* The meaning of scientific truthThis initiative ties directly into our ongoing efforts at The Origins Project Foundation to expand our impact and achieve our mission of enhancing your excitement and appreciation of the wonders of the cosmos, providing the public tools to better understand the challenges of the 21st century, and how to deal with them. By making these fundamental ideas accessible, we hope to inspire a deeper appreciation for the scientific method and its importance in creating the world we live in, and producing a better world tomorrow.Enjoy!As always, an ad-free video version of this podcast is also available to paid Critical Mass subscribers.

• (Rebroadcast) Noam Chomsky | Prescient Predictions? | Trump, Brazil, and American Fear

  This week, I’m excited to share a special rebroadcast from the Origins Podcast archives: my original Origins Podcast conversation with Noam Chomsky.We recorded this dialog over six years ago, as an update to a conversation we’d held three years prior , before the political upheavals of Trump and Brexit.Listening back now, it’s striking how much of what Noam said remains relevant, and in many cases, deeply prescient. As always, he was incisive, informative, provocative, and brilliant. We covered a huge range of topics, starting with the history of anti-intellectualism in America and the role of intellectuals during the Vietnam War , before moving into the nature of American exceptionalism.We also dove into the pressing foreign policy issues of the day, including North Korea, Syria, Israel, Venezuela, and Brazil. While many of the underlying causes may be the same, it’s fascinating to see how some of these situations have played out in ways we might never have predicted.From his analysis of free speech debates to his critical concerns about nuclear weapons and the environment, it’s a conversation that remains incredibly important.I hope you enjoy revisiting this fascinating conversation.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

  As we move into the end of the year, I’m excited to return to our recurring series “What’s New in Science” with my co-host Sabine Hossenfelder. In this month’s episode, we started by tackling a favorite subject: scientific hype. Sabine kicked things off by dissecting a recent, highly suspect press release claiming a million-qubit quantum computer is on the horizon. I then brought up a National Geographic article claiming that “warp drive is speeding closer to reality” , and we discussed the reasons why it actually isn’t, including the need for “negative energy,” that keep it firmly in the realm of science fiction.From there, Sabine steered us into the world of academic accolades, discussing the controversy around last year’s Nobel Prize in Physics for work on neural networks and the collaborative nature of science. I then introduced this year’s prize, which was awarded for the beautiful and precise experimental work on seemingly macroscopic manifestations of quantum mechanics—specifically, showing a superconducting quantum state can “tunnel” through a barrier.Finally, we turned to cosmic mysteries. Sabine presented a report on search for “Dark Stars,” a theory that the first stars might have been powered by dark matter annihilation , which require some wishful thinking and what I think are not particularly well motivated physics. For full disclosure this is an issue I thought about in a slightly different context almost 40 years ago and have some a priori skepticism about. I closed with a much more plausible bit of exotic physics that may have been observed: new observations of long-lived gamma-ray bursts. A new model suggests these are caused by a black hole that has merged with a star and is consuming it from the inside out. From wild hype to implausible and plausible models to Nobel-winning physics, I hope you enjoy the conversation.As always, an ad-free video version of this podcast is also available to paid Critical Mass subscribers.

• Spooky Physics!

  In a special Halloween episode of the Origins Podcast, which I’ve have decided to call “Spooky Physics!”, I explore why you shouldn’t be afraid of the unknown, and in particular of supernatural gobbledygook. We look at the fundamental physics that debunks popular supernatural ideas.Take ghosts, for example. Physics is a two way street. If you can see a ghost, it must interact with light. But that very interaction, electromagnetism, is what stops you from walking through a wall. A ghost simply can’t have its cake and eat it too; it either goes through walls or you can see it. Not both.I also confront one of the biggest misuses of physics today: the co-opting of quantum mechanics. People seize on Einstein’s “spooky action at a distance” to argue that consciousness can change the universe just by thinking. This is complete nonsense. I explain what entanglement really is and why it does not allow you to affect things remotely, no matter how much you might want to.The moral of today’s topic is simple: don’t be afraid. And more importantly:The real universe, with its actual quantum wonders and black holes, is far more interesting than any supernatural fantasy. Enjoy Halloween…especially the candy.As always, an ad-free video version of this podcast is also available to paid Critical Mass subscribers.

• Gad Saad: Final Episode of The War on Science Interviews

  As The War on Science continues to circulate and reach readers around the world, I had the privilege of closing our Origins mini series, The War on Science Interviews, with my colleague and book contributor Gad Saad. It felt fitting to end the series with a candid and provocative conversation that reflects the spirit of the project itself.The essays and interviews collected around this book address a wide range of concerns: the ideological corruption of science, the erosion of free speech in academia, the replacement of scholarship with activism in many disciplines, and the disruptions now spreading from mathematics to medicine. We explore how cancel culture and DEI bureaucracies weaken excellence, how biology is distorted for political ends, and how false premises about gender and sex compromise both science and medicine. The conversations are blunt and challenging, but they also aim to outline principles that can help universities recover integrity, trust, and the courage to return to embracing free inquiry.Gad and I discussed many of these themes directly. He confronts the absurdities of modern campus culture, and his voice joins those the other contributors who have argued that ignoring these trends will not make them disappear. Many academics have hoped the problems would fade on their own. They have not. The internal culture war in academia must be confronted openly if scholarship and science are to thrive in the West.I am hopeful the book will spark debate in universities and among the wider public. If you would like the full context for this episode, you can watch the complete War on Science Interviews mini series at this link here. In the meantime enjoy this episode now.With this finale, Origins now returns to its regular biweekly release schedule. We have some fascinating new conversations, educational content, and science news in store that I am excited to share.As always, an ad-free video version of this podcast is also available to paid Critical Mass subscribers.
