...minority groups and women, and further, goals and time tables to which the contractor's good faith efforts must be directed to correct the deficiencies and, thus to increase materially the utilization of minorities and women at all levels and in all segments of his workforce where deficiencies exist...
...nearest star to the sun. Proxima Centauri, as it was about four years ago; and some of the farther galaxies as they looked billions of years ago. Peering into the heavens then is like looking back into time, and some of the stars that astronomers see may no longer exist. Truly, as André Schwarz-Bart wrote in The Last of the Just: "Our eyes register the light of dead stars...
...into the very cores of the stars. With increasing confidence, astrophysicists are answering some of the questions that man has asked from the time he became a rational being: How far away are the stars? What makes them shine? How long have they been there, and will they exist forever...
...Princeton Physicist Robert Dicke determined that if the universe indeed began as a fireball filled with intense radiation, a trace of that radiation should still exist and be detectable with a sensitive radio antenna. By a serendipitous coincidence, in the same year Arno Penzias and Robert Wilson of Bell Laboratories were using just such an antenna to listen to radio waves from the Milky Way. They had been puzzled by a faint background noise that seemed to be coming evenly from all parts of the sky. When they heard about Dicke's work, however, and compared the frequency...
...very massive star may have an even stranger fate. Driven by its own immense gravitation, it collapses through its neutron star stage, crushing its matter into a volume so small that it virtually ceases to exist. The gravity of its tiny remnant is so great that nothing, not even light, can escape from it. All external evidence of its presence disappears, and the star, like the Cheshire cat, vanishes, leaving behind only the grin of its disembodied gravity. Anything that fell into such a "black hole" would quite literally be crushed out of existence...
