Fashion, Faith, and Fantasy in the New Physics of the Universe

In this provocative book, Roger Penrose argues that the fields of string theory, quantum mechanics, and cosmology are influenced by fashion, faith, and fantasy, which may be leading researchers astray.

The book is based on lectures given at Princeton University and is aimed at general readers with a non-technical approach.

Penrose critiques string theory's extra dimensions, the uncritical acceptance of quantum mechanics, and the fantastical ideas in cosmology, while also presenting his own theories such as conformal cyclic cosmology.

The work offers an important and insightful critique of contemporary fundamental physics from one of its most eminent figures.
