But the axis of the earth is a special direction either way. Does the universe have a special direction?

Spin? Hmmm. Relative to what? Are we spinning on the Earth? Depends on your reference frame!

Does the universe (as a whole) spin? What would that even mean, other than violating isotropy?
Thanks,

P.S. Apparently there is controversy about whether there is an observed bias in the direction of spin of surveyed spiral galaxies; if it were so and general, what would that imply about non-zero angular momentum for the whole universe?
