Podcast:The Art Bell Archive Published On: Wed Aug 20 2025 Description: Art Bell welcomes theoretical physicist Dr. Michio Kaku to discuss his book Einstein's Cosmos and the approaching 100th anniversary of relativity. The conversation ranges from the GPS system's dependence on Einstein's equations to the nature of time travel, with Dr. Kaku explaining that forward time travel is already proven through satellite measurements while backward time travel remains theoretically possible through hundreds of solutions to Einstein's general relativity equations.Dr. Kaku addresses the Mexican Air Force UFO footage, acknowledging it as one of the few percent of sightings that genuinely confounds physicists because it involved multiple observers using radar, infrared, and visual confirmation simultaneously. He argues that a Type III galactic civilization could theoretically use wormholes rather than conventional spacecraft, bypassing the vast distances between stars.The discussion turns to quantum computers, DNA computing, and the many-worlds interpretation of quantum mechanics. Dr. Kaku explains that parallel universes may coexist in the same room at different frequencies, much like radio stations broadcasting simultaneously. He warns that Moore's Law will collapse around 2020 and that Silicon Valley risks becoming a rust belt without investment in quantum and molecular computing technologies.
