Over the millennia many philosophers must have been inspired by the stars and mused about our role in this vast Universe. But how can philosophy inspire cosmology? Will we ever know everything about the Universe, what do our models of its evolution really tell us, and what does the strange physics that underlies them mean?

Establishing the philosophy of cosmology is a joint project of the Universities of Cambridge and Oxford bringing together philosophers and physicists to do just that. Plus has been following its progress. On this page you can find articles and podcasts based on interviews with participants in the project.
