Science fiction, science fact: What is time?
What is time? In the latest online poll of our Science fiction, science fact project you told us that you'd like an answer to this question. So we went to ask the cosmologist and theoretical physicist Paul Davies about the nature of time and revisited the musings of cosmologist John D. Barrow on the beginning of time and the physicist Kip Thorne's take on time travel. We also bring you two timely articles from FQXi who are our partners on this project. Happy reading!
And don't forget to vote for the next question you'd like to have answered!
