By observing the brightness of distant dying stars, astronomers have long come to believe that the expansion of the universe is accelerating. In fact, that apparent reality is deeply built into cosmological models: a mysterious force that influences the universe on the largest scales, dubbed dark energy, is believed to explain the acceleration. However, not everybody agrees with this widely accepted scientific consensus.

Discordance fits into the class of conventional popular cosmology, in so far that it is an account of how our present understanding of the Universe has emerged. But it is also, with some exceptions, more historically correct than other similar books. Baggott's book is a masterpiece that combines depth with clarity and comprehensiveness with readability. It presents modern cosmology as an unfinished business, rather than as the final conclusion on what the Universe is all about.
