Three Articles on the Expansion of the Universe 1997-1998 (reported by James Glanz) **First report of the Acceleratig Expansion of the Universe.** James Glanz. (Neta Bahcall and others) "New Light on Fate of the Universe," in "Science," published by the AAAS, vol 278, 11 October 1997, on pp 799-800, in the issue of pp 774-978. Original wrapper. FINE copy. "Exploding Stars Seen Billions of light-years away have given a preliminary verdict: the universe may be doomed to expand forever". James Glanz. "Exploding Stars Point to a Universal Repulsive Force" in "Science". Vol 279, 30 January 1998, pp 621-768, with the Glanz article on pp 651-652. "At the meeting of the American Astronomical Society in Washington, D.C., earlier this month, Saul Perlmutter of Lawrence Berkeley National Laboratory in Berkeley, California, announced that he and an international team of observers have now studied a total of 40 far-off supernovae, using them as beacons to judge how the cosmic expansion rate has changed over time. Not only did the results support the earlier evidence that the expansion rate has slowed too little for gravity ever to bring it to a stop; they also hinted that something is nudging the expansion along. If they hold up, says Perlmutter, "that would introduce important evidence that there is a cosmological constant."(from the article) "It would be a magical discovery," adds Michael Turner of the University of Chi- cago. "What it means is that there is some form of energy we don't understand." Other observers had already found signs that the universe contains far less mass than the main- stream theory of the big bang predicts, which left open the possibility that some form of energy in empty space could be making up the deficit." James Glanz, Alexi Filippenko. "Astronomers See a Cosmic Antigravity Force at Work" in Science, 27 February 1998, volume 279, number 5355, pp 1298-1299. Original wrappers Very Fine copy. With the Glanz article on pp 1298-1299 in the full issue. [++] This is a very early announcement reporting on the acceleration of the expansion of the universe. "Seemingly in defiance of common sense, space itself appears to be permeated by a repulsive force that is counteracting gravity on large scale. "Team member Alexei Filippenko announced last week that observed dimness of the supernovae pointing to unexpectedly great distances implies that cosmic expansion has actually sped up in the billions of years since the stars exploded." 714.3.…
