[astro-ph/0703325] Does the Universe Have a Handedness

An interesting observation - but it is not clear from this paper if the handedness bias seen in the SDSS spiral galaxies is really significant. There will be some correlation between the rotation axis and handeness of nearby galaxies, and this has not been taken into account. I imagine the ~2.9 sigma result would be reduced.

The analysis has been done in the equatorial coordinates only, with results binned by RA (averages taken over declination). The signal might be stronger in a different frame...
