Sean Carroll in Preposterous Universe:
I remember vividly hosting a colloquium speaker, about fifteen years ago, who talked about the LIGO gravitational-wave observatory, which had just started taking data. Comparing where they were to where they needed to get to in terms of sensitivity, the mumblings in the audience after the talk were clear: “They’ll never make it.” Of course we now know that they did, and the 2016 announcement of the detection of gravitational waves led to a 2017 Nobel Prize for Rainer Weiss, Kip Thorne, and Barry Barish. So it’s a great pleasure to have Kip Thorne himself as a guest on the podcast. Kip tells us a bit about he LIGO story, and offers some strong opinions about the Nobel Prize. But he’s had a long and colorful career, so we also talk about whether it’s possible to travel backward in time through a wormhole, and what his future movie plans are in the wake of the success of Interstellar.
