This article: http://physicsworld.com/cws/article/news/2011/jul/25/was-the-universe-born-spinning asserts that the universe was "born spinning" and that there is a preferred rotation direction for galaxies in the universe. My question is whether there is a preferred galaxy orientation in the universe, that is, whether there is a preferred plane for the galaxy disk?

1$\begingroup$ Correct me if I'm wrong, but given that orientation is relative in space, how COULD there be a preferred direction? When no one can say which way is up, who can say which way is clockwise? $\endgroup$ – Nerrolken Jan 9 '14 at 1:46

2$\begingroup$ You can compare the angular momentum vector of the plane of a disk galaxy to one another, so it's relative to one another. $\endgroup$ – astromax Jan 9 '14 at 13:26

$\begingroup$ galaxies seem to have a preferred orientation relative to their embedding large scale structure filaments arxiv.org/abs/1308.2816 $\endgroup$ – chris Mar 15 '14 at 20:56

There is no evidence for that. That's either a systematic observation error, or a random result within usual statistical fluctuations, compare this Q&A site.
