Super Structure - Evidence for Handedness Spiral Galaxies

  1. Aug 8, 2012 #1
    There is observational evidence for preferred alignment of spiral galaxies with alignment to the so called axis of evil in the CMB (cosmic microwave backgound 2.75K) data.

    The 'Axis of Evil' has been a controversial topic. Even the originator of the term has shown a change of heart [The Axis of Evil revisited: http://arxiv.org/abs/astro-ph/0611518] [Broken]. A posteriori statistics are a notorious source of 'amazing' discoveries. Certain researchers have made a career out of them [e.g., Halton Arp]. See http://www.universetoday.com/55200/seven-year-wmap-results-no-theyre-not-anomalies/ and http://www.independent.co.uk/news/science/the-universe-the-new-axis-of-evil-465199.html for discussion. The handedness 'anomaly' has been known since the early SDSS data releases, but, its significance [if any] is not well understood. Marcelo Berman hypothesizes it could be evidence for 'rotation' of the universe - e.g., http://arxiv.org/abs/physics/0610003. Other studies suggest the possible degree of rotation is very tightly constrained - e,g., http://arxiv.org/abs/0902.4575

    The alignment of spiral galaxy spins is interesting. Interesting that no one asks why?

    The CMB is a tough nut to understand. I can make no predictions concerning that one.

    The observational data indicates there are super structures. I believe that is not in contention. There are super structures.
