Space Forum / Astronomy / March 2008

As I understand it, nominally, 1::1, a requirement
for the general belief that the universe is
isotropic. The Galaxy Zoo project
(http://www.galaxyzoo.org), which attempted to count
that ratio directly, as seen from Earth, seemed to
find otherwise, and got a lot of excitement out of
that preliminary indication of possible anisotropy,
but after careful bias testing of the same group of
classifier volunteers, the result proved to be
"classifier-person bias" rather than real universe
bias.

Had the anisotropy proved real, quite a bit of
astrophysics / cosmology theory would have needed
revision, apparently.

To put a little better answer in place than my prior
amateur summary, there is now (as of 2008/03/27) a
published analysis from the Galaxy Zoo project:

"We conclude that the Galaxy Zoo spin results are
consistent with statistical isotropy."
