The Concept of a Rotational Universe

[Mike Smith Cosmos]

Rotation seems to be a fundamental attribute of many aspects of reality: from particles; to planets; to moons; to stars; to star systems; to galaxies.

 

So why not the whole Universe ?

A global rotation about some axis would violate the cosmological principle. I also read that it is hard to derive cosmologies that have global rotation from general relativity.

 

However, I think the best observational evidence for a rotating Universe would be in the CMBR. To my knowledge there is little evidence to suggest a rotating Universe. The non-Gaussian properties on the CMBR could be consistent with a "slowly" rotating Universe [2]. But this is rather speculative in my opinion.

 

Galaxy studies also suggest that there maybe some large scale or global rotation [1].

 

The suggestion that Universe has a global rotation has always been viewed with a lot of scepticism. I don't see that changing unless very clear evidence is found.

The concept of rotational Universe is related to the shape of Universe. Does Universe have another kind of force to hold all galaxies together?

Not that we know of. The effect of rotation on the formation of galaxies was investigated in [1].

What would it be rotating relative to ?? See Newton's and Mach's 'bucket of water' thought experiment.

 

And, does rotation not imply a centre to the universe ? Or, at the very least, does rotation of the universe imply a 'preferred' direction, thereby undermining symmetry and momentum conservation laws ??

[Mike Smith Cosmos]

Research done by the Refs of AJB in previous posts seems to indicate there is evidence for a rotation of the whole universe of about one ten trillionth (10exp -13) of a radian per year.

 

This seems to be demonstrated by the rotation of galaxies produced by the corriolis effect and eddy currents . This is in relation to the overall structure of the universe.

These are all reasons why it is difficult to really understand what is meant by a rotating Universe and the reasons why people are always very sceptical.

Most of the principals of Mach, Newtons Bucket , gravity , depend on mass influencing other mass. As yet we do not appear to understand where all the mass comes from . In the standard model of particles where 99 % of the mass is missing , ( if I understand it right ), where baryonic quark matter is only responsible for 1 % of mass. We appear to be waiting on the results of large hadron collider research to see if a field exists and a boson ( Higgs field & Higgs boson ) to cause the 99 % mass to be introduced to to all barionic matter within the standard model . It seems to be very quiet from the LHC at the moment. Is there any hint yet of Higgs predictions being verified .

 

Whether a Higgs field or a Wilczec grid of quantum field there appears to be some form of relative field against which a rotating universe could possibly said to relate.

 

In the Newton bucket thought experiment there was always the curvature of the water as it rose up the side of the bucket under the action of centrifugal force which Newton said could still give indication of a rotation.

 

Could we possibly not look for an outward thrust acting within the rotating universe equivalent of the curved surface in Newtons bucket. Say Dark Energy ?

 

Center. Yes. Well if it was proved ( which although there appears to be some fairly thorough research being currently undertaken via galaxy and galaxy cluster formation , is not yet proven ) a center of rotation must exist , as with an individual galaxy. Also if the universe was shown to be similarly egg shaped like a galaxy then a center would exist somewhere . Interesting.

According to the Discovery Channel documentary How the Universe Works -- Black Holes, our cosmos accords with the GR equations, of a Black Hole. If you "plug in the values of the mass of the universe, radius of the universe", it turns out, that our cosmos could exist inside the event horizon, of a BH. What if our cosmos is, in some way, the product, of a rotating BH ?
