Re: [Phys-L] As the universe turns

[Anthony Lapinski <alapinski@pds.org>]

I agree with what Tom said earlier.

Regarding a spinning universe, would this be like the cosmological
principle? Every observer would be at the center of that rotation.
And like the Hubble Law, farther objects would be spinning (orbiting)
faster. How would this affect light that we see from distant galaxies?
And would the CMB be different? I think the evidence suggests the universe
is not spinning.
