Solving the mysteries of the universe is usually about finding the best answer to a question. But what if we are not even asking the right questions?
A pioneer in quantum computation, University of Oxford physicist and best-selling author David Deutsch has spent most of his career working towards a new way of asking questions about the universe. Deutsch's vision for this "theory of everything" ties together ideas in cosmology, computation, philosophy and evolution to describe the nature of reality.
It has been suggested that his long-awaited theory could account for several fundamental mysteries, such as why time flows in only one direction – a property that is not required by most physical laws. Now Deutsch has posted a taste of the form his theory might take, opening the door to what may become a new branch of physics.
