Big Bang contd...
Article Abstract:
The Big Bang theory of an expanding universe lacks experimental and observational confirmation. This theory, though widely supported by astrophysicists, fails to account for such phenomena as the origin of galaxies, the lack of 'missing mass,' and the inability to find traces of the Big Bang explosion in the microwave background radiation. On the other hand, the characteristics of the background radiation do seem to necessitate an expanding Universe. Moreover, no thoroughly proven observation has been found to invalidate the Big Bang theory.

The search for dark matter (contd)
Article Abstract:
Jes Madsen of the University of Aarhus has written an intriguing article on how the 17 keV neutrinos may have influenced the existence of hot and cold dark matter. The article, entitled 'Bose condensates, Big Bang nucleosynthesis and cosmological decay of a 17keV neutrino' and published in the Jul 27, 1992 issue of Physical Review Letters, also argues that the 17 keV neutrinos may have affected temperatures and the production of heavier particles during the Big Bang.

Big Bang not yet dead but in decline
Article Abstract:
The latest findings of scientists using the Hubble Space Telescope have shed doubt on the Big Bang theory of the origin of the universe. The Hubble constant (Ho), calculated using the recession speed of clusters of galaxies, suggests that the age of the Universe is much smaller than those of stars in globular clusters of our galaxy. To prove this finding, more data on astronomical measurements is required.
