But what if, nonetheless, Einstein got it wrong?Since the 1930s, physicists have noticed an alarming discrepancy between the universe as we see it and the universe that Einstein's theory of relativity predicts. There just doesn't seem to be enough stuff out there for everything to hang together. Galaxies spin so fast that, based on the amount of visible matter in them, they ought to be flung to pieces, the same way a spinning yo-yo can break its string. Cosmologists tried to solve the problem by positing dark matter—a mysterious, invisible substance that surrounds galaxies, holding the visible matter in place—and particle physicists, attempting to identify the nature of the stuff, have undertaken a slew of experiments to detect it. So far, none have.Now, John W. Moffat, a physicist at the Perimeter Institute for Theoretical Physics in Waterloo, Canada, offers a different solution to the problem. The cap­stone to a storybook career—one that began with a correspondence with Einstein and a conversation with Niels Bohr—Moffat's modified gravity theory, or MOG, can model the movements of the universe without recourse to dark matter, and his work chal­lenging the constancy of the speed of light raises a stark challenge to the usual models of the first half-million years of the universe's existence.This bold new work, presenting the entirety of Moffat's hypothesis to a general readership for the first time, promises to overturn everything we thought we knew about the origins and evolution of the universe.

    Historical records are first found in Babylon and Egypt, and after two millennia the arithmetical astronomy of the Babylonians merged with the Greek geometrical approach to culminate in the Almagest of Ptolemy. This legacy was transmitted to the Latin West via Islam, and led to Copernicus's claim that the Earth is in motion. In justifying this Kepler converted astronomy into a branch of dynamics, leading to Newton's universal law of gravity. The book concludes with eighteenth- and nineteenth-century applications of Newton's law, and the first explorations of the universe of stars.

    For the first time NASA has allowed 900 of its 'master' negatives and transparencies to be taken offsite for electronic scanning so as to produce the sharpest images of space that we have ever seen. From this selection of 'master' photographs Michael Light has distilled a single composite journey beginning with the launch, followed by a walk in space, and orbit of the Moon, a lunar landing and exploration and a return to Earth with an orbit and splash-down. Five enormous gatefold panoramas show the extraordinary lunar landscape.These photographs reveal not only the hardware of lunar exploration in exquisite details but also the profound aesthetics of space in what could be described as the ultimate landscape photography. The reader is encouraged to view these pictures as more than a spectacle. You start to experience them with a sense of the accompanying disorientation and excitement that the astronauts themselves would have felt. The Moon's surface and its extraordinary light are presented with awesome clarity.Full Moon was originally published in 1999 to mark the 30th anniversary of the first landing on the Moon. It was a milestone publication for the millennium, greeted with acclaim worldwide and published in eight countries. This new compact edition preserves all the superb quality of reproduction which was so evident in the original and makes this extraordinary work available to a still wider readership.
