...mission of 1975, whose main theme was mutual assistance in space. Besides, which would be more embarrassing: To ask the Russians for help, or to face possible casualties, billion-dollar indemnification suits and unforeseen political consequences if 85 tons of flaming fragments land in some sensitive region of the earth...
...scientific meeting in Manhattan, Lowell Wood, a young physicist from California's Lawrence Livermore Laboratory, delighted his colleagues (although he did not exactly convince them) with a plan to give the earth a virtually limitless energy supply. He suggested tapping the energy of a mini-black hole in orbit around the planet. From a spacecraft orbiting at a safe distance, pellets would be fired at the hole. This would create so much heat that the energy could be converted into microwaves and beamed down to earth. Even Wheeler, who is now at the University of Texas, and his former student...
Besides the possible black hole in Cygnus, one appears to be part of another double-star system in the constellation Scorpius (the Scorpion). Three more may have been detected, each at the heart of a globular cluster of stars in the halo of the earth's Milky Way galaxy. In the inner regions of these clusters, which contain tens of thousands of individual stars, some of the stars are revolving with wobbly motions, as if disturbed by a center of enormous gravity. Herbert Gursky and Andrea Dupree of the Harvard-Smithsonian Center for Astrophysics believe that these stars "may well...
While black holes may be hard to sight in the heavens, they are gaining high visibility on earth. They are the current rage of astrophysics, a marriage between the older disciplines of astronomy and physics. Says Astrophysicist W. David Arnett of the University of Chicago: "Black holes are where it's happening these days." Hardly a week passes without the publication of some jarring new conclusion or insight about black holes in the scientific journals. In one of several
