...tide of the people, have shifted fast to the right and co-opted the G.O.P.'s position. But the fellow who is sworn in as President on Jan. 20, 1981-Jimmy or Jerry or Teddy or somebody-will inherit an economy that, Greenspan feels, will rise with a bang...
Black holes apparently come in both economy and giant sizes. The gifted British theoretical physicist Stephen Hawking has shown mathematically that tiny black holes, dating back to the very origins of the universe, could exist. In the Big Bang, the primordial explosion that created the universe some 15 billion to 20 billion years ago, matter was hurled in all directions. In some places, Hawking says, quantities of matter roughly equivalent to the amount in a mountain may have become compressed enough to collapse, forming what he calls mini-black holes. Their circumference, as measured by their event horizons, could...
...were all but invisible in the mirrors and lenses of ordinary optical telescopes. Other signals came from the distant and powerful quasars. At Bell Telephone Labs, scientists working on a new satellite communications system even "heard" a low-level microwave hiss that may be lingering radiation of the Big Bang...
...that discovery be? For one thing, proof of the existence of black holes would clear away some of the mystery about both the evolution and the fate of the universe. Scientists generally agree that the universe is expanding, that its galaxies are still rushing outward from the original Big Bang. But they are uncertain about whether the expansion will continue forever. True, gravitational attraction among the galaxies is slowing the outward rush, but unless there is sufficient mass in the universe, the expansion will never completely halt...
After three years of prodigious calculations, he determined that some black holes must have been created during the birth of the universe, in the cataclysmic explosion called the Big Bang. These black holes, as opposed to those formed later by the collapse of stars, are minuscule; their event horizons are no larger than the circumference of a proton or other atomic particle. Subsequently, he found that they seemed to be radiating energy. That was such a startling break with the accepted concept of black holes that Hawking at first doubted his results. But no one has yet uncovered flaws...
