Does the Universe Have a Handedness?
===================================

 I have studied the distribution of spiral galaxies in the Sloan Digital Sky Survey (SDSS) to investigate whether the universe has an overall handedness.  A preference for spiral galaxies in one sector of the sky to be left- handed or right-handed spirals would indicate a preferred axis in the Universe.  The SDSS data show a strong signal for such an asymmetry.  Its axis seems to be strongly correlated with that of the dipole, quadrupole and octopole moments in the WMAP microwave sky survey, an unlikely alignment that has been dubbed "the axis of Evil".  Our Galaxy has its axis along the same direction.
     I propose a mechanism that explains all of these alignments in terms of a large-scale cosmic magnetic field.
