When does a story about science become science fiction? Cosmologist Lawrence Krauss and theoretical physicist Brian Greene discuss how to spin a yarn about string theory or the Big Bang, without hyping the science. And novelist Ian McEwan, whose books touch on neurosurgery and quantum field theory, talks about what science offers to fiction.
