The End Of The Old-Model Universe

That cosmology is in flux is apparent in the following sentence found in Nature:

" The standard ideas of the 1980s about the shape and history of the Universe have now been abandoned -- and cosmologists are now taking seriously the possibility that the Universe is pervaded by some sort of vacuum energy, whose origin is not at all understood."

Does this mean that the Big Bang, the mainstay of the astronomy we were taught in school, is now being cast aside? After all, the Big Bang does model fairly well three important observations:

  1. The apparent expansion of the universe;
  2. The 3K microwave background; and
  3. The abundances of the light nuclei.

But try as they may, cosmologists have not been able to coax the Big Bang model to explain the large-scale lumpiness and structure of the galaxies and galaxy clusters. One problem with the Big Bang is that it has too many free parameters -- too much theoretical slack. Many cosmologists are now looking for a better model. This better model, to use the words of P. Coles, should be more "exciting" and "stranger," something "perhaps not even based on General Relativity."

(Coles, Peter; "The End of the Old Model Universe," Nature, 393:741, 1998.)

Questions. Isn't cosmology already already "strange" enough? Since when do theories have to be "exciting"? If a vacuum is defined as "a volume devoid of mass," how can it contain energy when E = mc2 ?

Quotes

  • "A sourcebook of unexplained phenomena is therefore a valuable addition to a collection of scientific literature. William R. Corliss has provided this in the past with his source books of scientific anomalies in several subjects, and now he has provided it for astronomy. He has done an excellent job of collecting and editing a large amount of material, taken in part from scientific journals and in part from scientific reporting in the popular or semi-scientific press." -- "The Mysterious Universe: A Handbook of Astronomical Anomalies", reviwed by Thomas Gold, Cornell University, in Icarus, vol.41, 1980

  • "An interesting, systematic presentation of unusual weather [..] This book is recommended for a general audience" --"Corliss, William R., Tornados, Dark Days, Anomalous Precipitation, and Related Weather Phenomena, Sourcebook Project, 1983.", revieweed in Choice, September 1983
  • "..the science is necessarily somewhat speculative, but Corliss's symthesis is based on reputable sources." -- "Corliss, William R. (Compiler). Lightning, Auroras, Nocturnal Lights, and Related Luminous Phenomena" reviwed by Joseph M. Moran, Univ. of Wisconsin in Science Books and Films, Sep/Oct 1983

  • "Before opening the book, I set certain standards that a volume which treads into dangerous grounds grounds like this must meet. The author scrupulously met, or even exceeded those standards. Each phenomenon is exhaustively documented, with references to scientific journals [..] and extensive quotations" -- "Book Review: The moon and planets: a catalog of astronomical anomalies", The Sourcebook Project, 1985., Corliss, W. R., Journal of the Royal Astronomical Society of Canada, Vol. 81, no. 1 (1987), p. 24., 02/1987
