...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 mistake of his scientific career...
...physicists thought Einstein's lonely quest was hopeless, and in fact he never succeeded. But Einstein was convinced such a basic harmony and simplicity existed in nature...
...that view has undergone a dramatic change. Says West German Physicist Carl Friedrich von Weizsacker: "Einstein's true greatness lies in the fact that he remains relevant today, in spite of the breakthroughs that have occurred since his death." Indeed, it is many of those breakthroughs that have contributed to the Einstein revival...
Radiating prodigious amounts of energy, they are visible on earth despite the fact that they may be the most distant objects in the universe. Pulsars, or neutron stars, have also been detected; these highly compressed cadavers of massive stars usually signal their existence by their highly regular radio beeps. Even stranger are the giant stars that may have in effect gone down the cosmic drain: those elusive black holes, with gravitational fields so powerful that not even light can escape them. Astronomers have also picked up what may be the echo of the Creation. Coming from everywhere in the skies...
...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...
