Time travel is a familiar theme of science fiction, but is it really possible? Surprisingly, time travel is not forbidden by the laws of physics - and John Gribbin argues that if it is not impossible then it must be possible. Gribbin brilliantly illustrates the possibilities of time travel by comparing familiar themes from science fiction with their real-world scientific counterparts, including Einstein's theories of relativity, black holes, quantum physics, and the multiverse, illuminated by examples from the fictional tales of Robert Heinlein, Larry Niven, Carl Sagan and others. The result is an entertaining guide to some deep mysteries of the Universe which may leave you wondering whether time actually passes at all, and if it does, whether we are moving forwards or backwards. A must-read for science fiction fans and anyone intrigued by deep science.
Author
John R. Gribbin is a British science writer, an astrophysicist, and a visiting fellow in astronomy at the University of Sussex. The topical range of his prolific writings includes quantum physics, biographies of famous scientists, human evolution, the origins of the universe, climate change and global warming. His also writes science fiction. John Gribbin graduated with his bachelor's degree in physics from the University of Sussex in 1966. Gribbin then earned his master of science (M.Sc.) degree in astronomy in 1967, also from the Univ. of Sussex, and he earned his Ph.D. in astrophysics from the University of Cambridge (1971). In 1968, Gribbin worked as one of Fred Hoyle's research students at the Institute of Theoretical Astronomy, and wrote a number of stories for New Scientist about the Institute's research and what were eventually discovered to be pulsars. In 1974, Gribbin published, along with Stephen Plagemann, a book titled The Jupiter Effect, that predicted that the alignment of the planets in quadrant on one side of the Sun on March 10, 1982 would cause gravitational effects that would trigger earthquakes in the San Andreas fault, possibly wiping out Los Angeles and its suburbs. Gribbin repudiated The Jupiter Effect in the July 17, 1980, issue of New Scientist magazine in which he stated that he had been "too clever by half". In 1984, Gribbin published In Search of Schrodinger's Cat: Quantum Physics and Reality, the book that he is best known for, which continues to sell well 28 years after publication. It has been described as among the best of the first wave of physics popularisations preceding Stephen Hawking's multi-million-selling A Brief History of Time. Gribbin's book has been cited as an example of how to revive an interest in the study of mathematics. In 2006, Gribbin took part in a BBC radio 4 broadcast as an "expert witness". Presenter Matthew Parris discussed with Professor Kathy Sykes and Gribbin whether Einstein "really was a 'crazy genius' ". At the 2009 World Conference of Science Journalists, the Association of British Science Writers presented Gribbin with their Lifetime Achievement award.
