The multiverse has captured the imagination of scientists and thinkers for centuries, sparking debates in physics, philosophy, and beyond. But is it a valid scientific theory or just science fiction? I’ve had the pleasure of exploring this issue with the leading expert in this field, physicist and author Paul Halpern. Halpern is a professor of physics at Saint Joseph’s University and the author of eighteen popular science books, including Flashes of Creation, The Quantum Labyrinth, Einstein's Dice, Schrodinger's Cat, and Synchronicity. He is the recipient of a Guggenheim Fellowship and is a Fellow of the American Physical Society. Halpern recently published The Allure of the Multiverse: Extra Dimensions, Other Worlds, and Parallel Universes, which tells the epic story of how science became besotted with the multiverse and the controversies that ensued. Today, we’re going to dive headfirst into this fascinating investigation! Tune in.

My colleague Professor Jorge Hirsch joins me to discuss recent claimed breakthrough in high-temperature superconductors, including claims they work at near ambient pressure and temperture. Here come cheap magnetic levitating trains, low-loss power distribution, free MRI scanners in every clinic…. Or not? Watch my solo episode about the controversial claims here: https://youtu.be/hbER0AnwXD4 Since the discovery of superconductors in 1911 by Heike Kamerlingh Onnes, earning the 1913 Nobel Prize in Physics, they have been the subject of much fascination and inquiry. Some of the greatest minds in physics have grappled with how superconductivity works to drive electrical resistance to 0. The 1972 Nobel prize in Physics was awarded to John Bardeen, Leon Neil Cooper, and John Robert Schrieffer "for their BCS theory of superconductivity. Now the race is on to get the highest temperature superconductor possible; another Nobel Prize was awarded just for getting the temperature up to 35K or -396 Fahrenheit! Superconducting has remained impractical, until now... Maybe! The HUGE claim: zero resistance, at temperatures up to 65 degrees Fahrenheit.

This would be a major breakthrough, as superconductors are materials that conduct electricity without resistance. This would have a wide range of potential applications, including in power transmission, medical imaging, and quantum computing. However, the video also discusses some concerns about the validity of the research. The researchers have not yet published their findings in a peer-reviewed journal, and there have been some questions raised about the quality of their data. It is possible that the discovery is a fraud, or that it is not as significant as the researchers claim. It is too early to say whether the discovery is a breakthrough or a fraud. Key concepts discussed in the video: * Superconductors are materials that conduct electricity without resistance. * Room-temperature superconductors would have a wide range of potential applications, including in power transmission, medical imaging, and quantum computing. * The researchers at the University of Rochester claim to have discovered a room-temperature superconductor. * However, there are some concerns about the validity of the research. * It is too early to say whether the discovery is a breakthrough or a fraud.
