Information and cosmological physics

Abstract

Abstract.We have reviewed an information-theoretic approach to quantum cosmology, summarizing the key results obtained to date, including a suggestion that an accelerating universe will eventually turn around. PreambleThere are several intriguing approaches to quantum spacetime, and quantum cosmology, in particular. Here, we have described the work of a number of people involved in one endeavour: An information-theoretic approach to quantum cosmology. Spacetime limit has made this review brief and qualitative.
