Shortly after midnight, crack units of the Javidan guards, which had taken up positions along the road leading to the base, moved forward. As the fighting intensified and the gunfire became almost constant, private cars were commandeered to take the dead and dying to hospitals. One victim was Los Angeles Times Correspondent Joe Alex Morris Jr., 51, a veteran Middle East reporter, who was fatally shot in the chest by a bullet while watching the battle...
...expanding one. Because such a changing, dynamic universe was totally at odds with the popular picture of the heavens portrayed by most astronomers, Einstein had opted for a stable, unchanging universe; he had managed that feat with a mathematical sleight of hand that involved what he called the cosmological constant. A decade later, after the American astronomer Edwin Hubble had shown that the distant galaxies were all receding from one another and that the universe was indeed expanding, Einstein reversed himself and accepted the fact toward which his original equations had pointed. The cosmological constant, he allowed, was the worst...
...impossible to detect. Putting the theory into elegant mathematical form, the Dutch physicist Hendrik Lorentz added another idea: permeating the structure of all matter, the ether would also slow down clocks traveling through it?in fact, just enough so light's speed would always seem constant...
...notion of the ether. Then he went on to state two postulates: 1) An experiment can detect only relative motion, that is, the motion of one observer with respect to an other. 2) Regardless of the motion of its source, light always moves through emp ty space at a constant speed (this seems to violate common sense, which suggests that light projected forward from a moving spacecraft, like a bullet fired from a plane, would travel at a speed equal to its velocity plus that of the craft). From these statements, using thought experiments and simple mathematics, Einstein made deductions...
...actors arrived on the set, they worked hard and fast. Harewood, 28, an actor of enormous range who ages 50 years in the lengthy role of Alex's father, had to get by on three hours' sleep to keep up with memorizing his lines. Says he: "That constant struggle alone made me look 20 years older...
