As for something more substantial, I finally found Collins and Hawking’s full paper on THE ROTATION AND DISTORTION OF THE UNIVERSE, and it does not look good for any rotating universe hypothesis.

At the bottom of page 13 of his paper "Soft Hair on Black Holes", Stephen Hawking writes that the Compton wavelength [math]\lambda[/math] (is equivalent to) [math]\frac {\hbar}{M}[/math] when he was actually referring to the reduced Compton wavelength [math]\frac{\lambda}{2 \pi}[/math] not [math]\lambda[/math]. If you don't pick this one up your M will become [math]2 \pi[/math] larger than it should be, especially when [math]\hbar[/math] and [math]\lambda[/math] are both constant. .
