“…9 Importantly, this form of gravity makes entirely testable predictions. 10 Overall, quantum mechanics dovetails with thermodynamics and gravitation, and what happens on the smallest Planck scale ultimately connects with what happens on the largest cosmological scale. Nevertheless, this does not occur when we change the units of time.…”

The fundamental constants of thermodynamics, including Boltzmann's constant, Avogadro's number, and the fine structure constant, remain to date empirical. In this paper, the derivations of these fundamental constants and the equations of thermodynamics are explored. It is found that the constants of thermodynamics are related to the constancy of the speed of light and Planck's constant. Such findings result in greater mathematical insights into the relationship between the constants of thermodynamics and the fundamental constants of Nature as a whole.

[http://dx.Résumé: Les constantes fondamentales de la thermodynamique, comme la constante de Boltzmann, le nombre d'Avogadro et la constante de structure fine, restent à ce jour empiriques. Dans cet article, nous explorons comment sont dérivées ces constantes, ainsi que les équations fondamentales de la thermodynamique. Nous établissons que ces constantes sont reliées à la constance de la vitesse de la lumière et la constante de Planck. Une meilleure compréhension mathématique de la relation entre ces constantes et les constantes fondamentales de la Nature dans leur ensemble en découle.

“…Importantly, accurate predictions of black hole physics have been made (Worsley 2011), which are readily testable, using established methods (Schodel et al 2002). The advanced black hole physics presented here, also has the advantage that it obviates the need for the formation of infinitely dense singularities.…”

One of the most important unresolved issues of modern physics is the presence of cold dark matter (CDM). Such dark matter appears to be essential in explaining the observed galactic rotation curves and the missing Cosmological dark matter. Recent attention has focused on galactic halos as an explanation of the galactic rotation curves, and on the possibility that galactic halos may consist of massive compact halo objects (MACHOs). Indeed results of experiment by the MACHO collaboration group have confirmed the presence of MACHOs in the galactic halo at statistically significant levels. What remains unclear is, what percentage of the galactic halo can be explained by such MACHOs, and what these MACHOs are likely to be composed of. Recent research shows the "most plausible" candidates for such MACHOs are being identified as primordial black holes. Such primordial black holes can also explain quasar brightness, spectral variations, and multiply lensed quasar systems. The presence of these primordial black holes in the galactic halo can be further modelled using advances in black hole gravitational physics. Indeed it has previously been shown that advances in black hole physics can be used to accurately model both CDM associated with the supermassive black hole at the centre of the galaxy, and Cosmological cold dark matter. To establish whether the same mechanism applies to primordial black holes in galactic halos, the original data from the MACHO project are reanalyzed using these advances in black hole physics. It is concluded that the majority of the CDM mass of the galactic halo can be accounted for by MACHOs by using a reanalysis of the data, and by applying advances in black hole gravitational physics. Importantly these advances in black hole physics offer further readily testable gravitational predictions.Keywords: Primordial black hole, Gravitation, Black hole physics, Galactic halo, Cold dark matter, Cosmology IntroductionThe presence of CDM remains to date one of the most important unsolved mysteries of modern Cosmology. It is particularly important not only to the understanding of the large scale structure of the Universe, but also in explaining the formation of galaxies. To date the search has concentrated on two main forms of CDM; weakly interactive massive particles (WIMPs), and massive compact halo objects (MACHOs) (Cline 2003). While the presence of WIMPs or some other form of exotic particle is still the favoured model, there has been a recent increase in the interest in MACHOs. Indeed research indicates that the statistical likely hood of MACHOs being present in the galactic halo is high (Alcock et al. 2000a).The question however, remains as to how prevalent these MACHOs are in the galactic halo, and what form do these MACHOs take? Interestingly, a recent comprehensive review suggests that the most "plausible" form these MACHO's take is that of primordial black holes (Hawkins 2011). In that review, a wide range of experimental evidence from quasar brightness, spectral variations, and multip...
