The case against a massive black hole at the Galactic Centre
Article Abstract:
The existence of young blue stars near the central parsec of the Milky Way Galaxy indicates that the Galactic Center is not occupied by a massive black hole since the powerful tidal forces generated by such an object would have prevented the young stars from coalescing. The young blue stars were detected through analysis of the near-infrared source IRS16. This new evidence backs up the earlier argument that the existence of the compact radio source SgrA near the Galactic Center disproves the giant black hole theory.

More on modified dynamics
Article Abstract:
Modified dynamics (MOND) as a replacement for dark matter cosmology has more merit than D. Lindley indicated. MOND is far more than a slight adjustment of the inverse distance square law of gravity. Actually, lack of agreement between the low accelerations of galaxies provides the principal justification for MOND. MOND also successfully forecasts the rotation curve for particular galaxies based on the known distribution of stars and gas.
