...globe by heat and radiation -suddenly begin to fall inward toward the star's center of gravity. If the star is massive enough, the imploding gases gather such momentum as they fall that they virtually crush themselves out of existence at the stellar center. Using the formulas of Einstein's general theory of relativity, more recent theorists predict that as the star shrinks toward oblivion, the familiar rules of physics may be violated. Its mass becomes infinitely dense, yet occupies no space. Its gravitational pull becomes so intense that no light or other radiation can escape from...
...amplified on board and transmitted back to earth. The entire round trip took only about 43 minutes, but the results may be momentous for all of physics. Last week, at a conference on gravity at Caltech, the experimenters reported that they had gathered dramatic new evidence in support of Einstein's 1916 General Theory of Relativity...
Such support was needed. Although Einstein's theory offers the most comprehensive explanation of gravity since Newton formulated his gravitational laws, it has recently encountered its most serious challenge. One consequence of the theory is that light and other electromagnetic waves should be measurably bent when passing through a strong gravitational field. Contesting Einstein's equations, Physicists Robert Dicke of Princeton and Carl Brans of Loyola University (New Orleans) argued that such waves are bent to a lesser extent than Einstein had predicted. Though subtle and wrapped in complex mathematics, the differences in the two theories are extremely...
...path would be curved, not straight. The Brans-Dicke theory, on the other hand, predicts less curvature and a slowdown of only 186 millionths of a second. While such bending has been measured before, the tests have never been accurate enough to make a firm case for either the Einstein or Brans-Dicke theory...
Despite the odds stacking up against him. Physicist Dicke was not yet ready to surrender. "If this were a poker game," he said, "I would be staying with my hand." If Einstein were still alive, however, he would certainly be ready to raise...
