Is It Possible to Build a Time Machine? With Paul Davies

Author: John Michael Godier April 28, 2026 Duration: 21:46

Time travel is one of sci-fi’s favorite tools. But is it possible to build a real time machine? Could you travel into the future or the past? Paul Davies joins John Michael Godlier to discuss the possibilities of time travel and how it would work within Einstein’s theory of general relativity. Paul Davies is a theoretical physicist and regents professor at the department of physics at Arizona State University. He is a cosmologist, astrobiologist and best-selling science author, including the author of How to Build a Time Machine.https://amzn.to/2Q5IKNt (affiliate link)Patreon: https://www.patreon.com/EventHorizonShowFollow us at other places!Website: https://www.eventhorizonshow.com/Twitter: https://twitter.com/jmgeventhorizonInstagram: https://www.instagram.com/jmgeventhorizon/Music featured on Event Horizonhttps://stellardrone.bandcamp.com/https://migueljohnson.bandcamp.com/https://leerosevere.bandcamp.com/https://aeriumambient.bandcamp.com/FOOTAGE:NASAESA/HubbleESO - M.KornmesserESO - L.CalcadaESO - Jose Francisco Salgado (josefrancisco.org)NAOJUniversity of WarwickGoddard Visualization StudioLangley Research CenterPixabay
