Study validates general relativity on cosmic scale, existence of dark matter (page 2)
Sloan Digital Survey data provide test that rules out alternative theories of gravityAn analysis of more than 70,000 galaxies by University of California, Berkeley, University of Zurich and Princeton University physicists demonstrates that the universe ? at least up to a distance of 3.5 billion light years from Earth ? plays by the rules set out 95 years ago by Albert Einstein in his General Theory of Relativity.By calculating the clustering of these galaxies, which stretch nearly one-third of the way to the edge of the universe, and analyzing their velocities and distortion from intervening material, the researchers have shown that Einstein's theory explains the nearby universe better than alternative theories of gravity.One major implication of the new study is that the existence of dark matter is the most likely explanation for the observation that galaxies and galaxy clusters move as if under the influence of some unseen mass, in addition to the stars astronomers observe."The nice thing about going t
