Theories of Everything
What do physicists mean by a 'Theory of Everything'? And what do they mean by 'Everything'? Ever since 1982 there has been a focus of attention upon 'string theories' as possible Theories of Everything. What are these theories like and what remarkable things do they predict about our Universe?
Do they mean that physics is coming to an end? In this lecture we also look forward to some of the exciting developments that physics and astronomy may have in store for us in the next few years.
Professor John D. Barrow FRS has been a Professor of Mathematical Sciences at the University of Cambridge since 1999, carrying out research in mathematical physics, with special interest in cosmology, gravitation, particle physics and associated applied mathematics.
