The Singular Universe and the Reality of Time: A Proposal in Natural Philosophy is a book about cosmology, philosophy of time, metaphysics and scientific naturalism by the American theoretical physicist Lee Smolin and the Brazilian philosopher Roberto Mangabeira Unger. The authors argue that the current crisis in cosmology is a result of physicists making the wrong commitments to universalizing local experiments and to a block universe. They suggest instead that new research projects would be revealed if we took seriously the idea of one, and only one, universe as well as the reality of our experience of time. This new paradigm, they say, would also give rise to the revolutionary notion that the laws of nature might not be immutable. The book was initially published by Cambridge University Press on December 8, 2014. Source: Wikipedia (en)
