In the latest online poll of our Information about information project you told us that you'd like an answer to this question. We asked Seth Lloyd, an expert on information at the Massachusetts Institute of Technology, and here is an answer. We also bring you two related articles from FQXi who are our partners on this project. Happy reading!
Something called quantum field theory has been hugely successful in describing the fundamental forces and particles. But what exactly is it? This series of accessible articles traces the history of quantum field theory, from its inception at the beginning of the twentieth century to the tantalising questions that are still open today. It's a story of pain and triumph, hardship and success.
Science is much stranger than fiction. It suggests that our Universe may just be one of infinitely many which constantly pop in and out of existence like bubbles in a bubble bath. There may be many more dimensions that the three we can see and our Universe is riddled with black holes at whose centres time and space tear themselves apart. Intrigued? This ongoing project will bring you the latest research in physics with the help of researchers from Queen Mary, University of London.
