Query: Impact on cosmology of the celestial anisotropy of the short gamma-ray
  bursts   Recently the anisotropy of the short gamma-ray bursts detected by BATSE was
announced (Vavrek et al. 2008). The impact of this discovery on cosmology is
discussed. It is shown that the anisotropy found may cause the breakdown of the
cosmological principle.
