The Elephant In The Universe: Govert Schilling (#242)

In The Elephant in the Universe, Govert Schilling explores the fascinating history of the search for dark matter. Evidence for its existence comes from a wealth of astronomical observations. Theories and computer simulations of the evolution of the universe are also suggestive: they can be reconciled with astronomical measurements only if dark matter is a dominant component of nature. Physicists have devised huge, sensitive instruments to search for dark matter, which may be unlike anything else in the cosmos—some unknown elementary particle. Yet so far dark matter has escaped every experiment. Indeed, dark matter is so elusive that some scientists are beginning to suspect there might be something wrong with our theories about gravity or with the current paradigms of cosmology. Schilling interviews both believers and heretics and paints a colorful picture of the history and current status of dark matter research, with astronomers and physicists alike trying to make sense of theory and observation. Govert Schilling is an internationally acclaimed astronomy writer in the Netherlands. He is a contributing editor of Sky & Telescope, and his articles have appeared in Science, New Scientist and BBC Sky at Night Magazine. He wrote over fifty books (in Dutch) on a wide variety of astronomical topics, some of which have been translated into English, including Evolving Cosmos, Flash! The Hunt for the Biggest Explosions in the Universe, The Hunt for Planet X, and Atlas of Astronomical Discoveries. In 2007, the International Astronomical Union named asteroid (10986) Govert after him.
