Have you seen Christopher Nolan's Interstellar yet? It's generating a lot of discussion both about the story and the science, and as one of the characters explains in the movie, the science focuses around Einstein's theory of relativity. As the author of a new book about that theory, I thought I should weigh in on the movie.
At an international conference in Mexico a few years ago, Richard Dawkins, having expounded at length on how sexual natural selection explains life on Earth without any need for a "creator," went on to say, "And I am sure that something like the principle of natural selection operates in the physical universe as well." Sounds totally silly? Well, there's more to it: a huge irony.
