An Anomaly in the Angular Distribution of Quasar Magnitudes: Evidence
  for a Bubble Universe with a Mass ~10^21 M\odot
  Quasars provide our farthest-reaching view of the Universe. The Sloan Survey
now contains over 100,000 quasar candidates. A careful look at the angular
distribution of quasar magnitudes shows a surprising intensity enhancement with
a "bulls eye" pattern toward (alpha,delta) ~ (195{\deg}, 0{\deg}) for all
wavelengths from UV through infrared. The angular pattern and size of the
enhancement is very similar for all wavelengths, which is inconsistent with a
Doppler shift due to a large peculiar velocity toward that direction. The shift
is also too large to explain as a systematic error in the quasar magnitudes.
The general features of the anomaly can be explained by the gravitational
lensing of a massive bubble with Mlens ~ 10^21 M\odot, a lens radius ~350 Mpc,
and with the lens subtending an angle of \pm15{\deg} on the sky. It is
remarkable that the presence of such a massive bubble universe can explain not
only the anomalies in the angular distribution of quasar intensities, but also
anomalies in the distribution of luminous red galaxies, anomalies in the CMB,
and bulk flow discrepancies, all of which appear in roughly the same direction.
