Modern Cosmology: Science or Folktale?
Edited by Andy Ross
The current Big Bang paradigm has it that the cosmos is expanding out of an
initially dense state and that by looking outward into space, one can,
thanks to the finite speed of light, look back to much earlier epochs. This
understanding owes much to two accidents: astronomers' discovery of
redshifts in the spectra of distant nebulae and the fortuitous detection of
an omnipresent background of microwave noise, which is believed to be the
remnant of radiation from a hot and distant past. Set in the theoretical
framework of Einstein's general theory of relativity, such observations lead
to a model that makes predictions and can thus be tested.
AR (2007) I worry about this too. The Big Bang makes a fine theory, but dark matter and dark energy are patches motivated solely by the need to save the phenomena, which is a poor motive for such big fixes, and then lurking behind them both is the more dangerous issue of how to reconcile general relativity and quantum mechanics.
