I have no opinion on this topic; I just want to see what other people think.

I don't think a universe can rotate because that would mean it has an axis. The universe can't have an axis because it has no center or reference point from which things can be measured.

Agreed, if we are assuming the universe to be infinite there can be no center point or axis on which to rotate around.

The only way something can rotate is in spatial reference to something else....it is meaningless to say the universe is rotating.

Anything can rotate as long as it contains more than one point and has mass - like a rotating planet which will still have an equatorial bulge even without a universe. There are some theories that say that the bulge is dependent on a universe, but nothing certain and really no known way to check.

A rotating universe would not be isotropic so this would show up in the cosmic microwave background radiation. With the latest images of the CMBR this can be tested and some evidence has pointed to a rotating universe. Apparantly this helps to explain the big cold spot in WMaP.

Only if the universe is infinite.

If the universe is rotating that implies that there is a point (at it's axis) from which things can be measured.

If that were the case the speed of light could only be measured from that point.

What we have found is that the speed of light is always the same no matter where you measure it from.

There needs to be a external frame of reference, is this a God thing? What is the nature of the coordinate system in which the universe can be rotating? Are you contending that there is an absolute frame of reference in relation to which the universe is rotating?
