A New Quantum Gravity Framework Based on the Twintori Model of Cosmology. (Part 1)

Authors: Chris Forbes, Dan Visser
Comments: 18 pages

In this, the final paper in the recent series on the new twin-tori model of cosmology, the model is developed in a logical way. Its historical development is included, and what follows is a statement of the central axioms of the theory. The reasons for them are described and their use in the theory is shown. What then follows is a brief description of the cosmological side of the theory, and its application to large scale structures and astrophysics. The paper then begins to develop the opposite length scale of the model, that on the order of the nuclear scale and ranging down to planck scale physics and Quantum Gravity. The theory is developed by laying theoretical foundations and mathematical idea's and structures and building on these using phenomenology and statistical techniques to fit parameters for the theory, including the dark energy - dark matter coupling constants. Many basic simplified models are then set out in various dimensions and with varying degrees of physical relevance. The models are also tested against current theory using observations of various physical systems ranging from nuclear physics, both earth-bound and stellar, to galactic dynamics and rotations. Historical deatils are included to increase readability from a variety of backgrounds.

Further Research on the Quaoar Criterion

Authors: James Gunasekera
Comments: All databases and the source code are available. Abstract: Percentage of persons satisfying the criterion is higher than expected not only for Nobel Prize laureates, but also for winners of similar awards in similar categories: Ramon Magsaysay Award, Wolf Prize, Pulitzer Prize.

The main purpose of this study is to test the criterion and methods described in the article about Nobel Prize laureates[1] on other data. It was shown that the moments of birth of Nobel Prize laureates satisfy the so-called Quaoar criterion much more often than other moments. A random moment of time satisfies the criterion with probability around 0.245, but among the Nobel laureates 33.47% satisfy the criterion. Because there are 726 persons in five categories, this is a statistically significant deviation: 243 of them satisfy, while the mean value is 177.352, and the standard deviation is 11.535. Shape of the distribution is "bell curve". It was observed that deviation is higher if all laureates in Chemistry and Physics are excluded. +6.145 stdev if only 391 laureates in the remaining three categories are considered: Literature, Physiology/Medicine, Peace prize.

On the Radiation Problem of High Mass Stars

Authors: Golden Gadzirayi Nyambuya
Comments: 14 pages, 1 figure. Published: Research in Astron. Astrophys. 2010 Vol. 10 No. 11, pp.1137-1150

A massive star is defined to be one with mass greater than ~ 8-10M. Central to the on-going debate on how these objects [massive stars] come into being is the socalled Radiation Problem. For nearly forty years, it has been argued that the radiation field emanating from massive stars is high enough to cause a global reversal of direct radial in-fall of material onto the nascent star. We argue that only in the case of a non-spinning isolated star does the gravitational field of the nascent star overcome the radiation field. An isolated non-spinning star is a non-spinning star without any circumstellar material around it, and the gravitational field beyond its surface is described exactly by Newton's inverse square law. The supposed fact that massive stars have a gravitational field that is much stronger than their radiation field is drawn from the analysis of an isolated massive star. In this case the gravitational field is much stronger than the radiation field. This conclusion has been erroneously extended to the case of massive stars enshrouded in gas & dust. We find that, for the case of a non-spinning gravitating body where we take into consideration the circumstellar material, that at ~ 8 - 10M, the radiation field will not reverse the radial in-fall of matter, but rather a stalemate between the radiation and gravitational field will be achieved, i.e. in-fall is halted but not reversed. This picture is very different from the common picture that is projected and accepted in the popular literature that at ~ 8-10M, all the circumstellar material, from the surface of the star right up to the edge of the molecular core, is expected to be swept away by the radiation field. We argue that massive stars should be able to start their normal stellar processes if the molecular core from which they form has some rotation, because a rotating core exhibits an Azimuthally Symmetric Gravitational Field which causes there to be an accretion disk and along this disk. The radiation field cannot be much stronger than the gravitational field, hence this equatorial accretion disk becomes the channel via which the nascent massive star accretes all of its material.

Bipolar Outflows as a Repulsive Gravitational Phenomenon Azimuthally Symmetric Theory of Gravitation (II)

Authors: Golden Gadzirayi Nyambuya
Comments: 26 pages, 2 Figures, Published in Research in Astron. Astrophys. 2010 Vol. 10 No. 11, 1151-1176

Abstract This reading is part in a series on the Azimuthally Symmetric Theory of Gravitation (ASTG) set-out in Nyambuya (2010a). This theory is built on Laplace-Poisson's well known equation and it has been shown therein (Nyambuya 2010a) that the ASTG is capable of explaining - from a purely classical physics standpoint; the precession of the perihelion of solar planets as being a consequence of the azimuthal symmetry emerging from the spin of the Sun. This symmetry has and must have an influence on the emergent gravitational field. We show herein that the emergent equations from the ASTG - under some critical conditions determined by the spin - do possess repulsive gravitational fields in the polar regions of the gravitating body in question. This places the ASTG on an interesting pedal to infer the origins of outflows as a repulsive gravitational phenomena. Outflows are an ubiquitous phenomena found in star forming systems and their true origins is a question yet to be settled. Given the current thinking on their origins, the direction that the present reading takes is nothing short of an asymptotic break from conventional wisdom; at the very least, it is a complete paradigm shift as gravitation is not at all associated; let alone considered to have anything to do with the out-pour of matter but is thought to be an all-attractive force that tries only to squash matter together into a single point. Additionally, we show that the emergent Azimuthally Symmetric Gravitational Field from the ASTG strongly suggests a solution to the supposed Radiation Problem that is thought to be faced by massive stars in their process of formation. That is, at ~ 8 - 10M, radiation from the nascent star is expected to halt the accretion of matter onto the nascent star. We show that in-falling material will fall onto the equatorial disk and from there, this material will be channelled onto the forming star via the equatorial plane thus accretion of mass continues well past the curtain value of ~ 8-10M albeit via the disk. Along the equatorial plane, the net force (with the radiation force included) on any material there-on right up-till the surface of the star, is directed toward the forming star, hence accretion of mass by the nascent star is un-hampered.

Azimuthally Symmetric Theory of Gravitation I

Authors: Golden Gadzirayi Nyambuya
Comments: 12 pages, 2 figures, 3 tables, Published: MNRAS, Vol. 403, Issue 3, pp.1381-1392 doi:10.1111/j.1365-2966.2009.16196.x

From a purely none-general relativistic standpoint, we solve the empty space Poisson equation, i.e. ∇2Φ = 0, for an azimuthally symmetric setting, i.e., for a spinning gravitational system like the Sun. We seek the general solution of the form Φ = Φ(r, θ). This general solution is constrained such that in the zeroth order approximation it reduces to Newton's well known inverse square law of gravitation. For this general solution, it is seen that it has implications on the orbits of test bodies in the gravitational field of this spinning body.We show that to second order approximation, this azimuthally symmetric gravitational field is capable of explaining at least two things (1) the observed perihelion shift of solar planets (2) that the Astronomical Unit must be increasing - this resonates with the observations of two independent groups of astronomers (Krasinsky & Brumberg 2004; Standish 2005) who have measured that the Astronomical Unit must be increasing at a rate of about 7.0±0.2m/cy (Standish 2005) to 15.0±0.3m/cy (Krasinsky & Brumberg 2004). In-principle, we are able to explain this result as a consequence of loss of orbital angular momentum - this loss of orbital angular momentum is a direct prediction of the theory. Further, we show that the theory is able to explain at a satisfactory level the observed secular increase Earth Year (1.70±0.05ms/yr;Miura et al. 2009). Furthermore, we show that the theory makes a significant and testable prediction to the effect that the period of the solar spin must be decreasing at a rate of at least 8.00 ± 2.00 s/cy.
