One of the scientists I follow in my book is Steve Giddings, a theoretical physicist at U.C. Santa Barbara who is also a highly skilled mountain-climber. In this video, he explains how quantum mechanics, when applied to black holes, calls the principle of locality into question and suggests that spacetime is not a fundamental ingredient of nature. The filmmaker is Gary Smaby, who was an artist-in-residence at the Kavli Institute for Theoretical Physics in Santa Barbara in 2012, at the same time I was the writer-in-residence there.
