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...

In this paper we find that the equations for gravity can be adapted by defining the equations for the curvature of space–time in terms of geodesics. Using these equations, we translate this curvature back into equations for an advanced Newtonian force of gravity. Using worked examples, we can show that the advanced Newtonian equations give results that technically agree exactly with gravitational experiment. These equations also technically agree exactly with binary pulsar data. At the same time these gravitational equations resolve the difficulties with the formation of singularities. Importantly, advanced Newtonian gravity provides readily testable gravitational predictions, particularly in the vicinity of black holes.

One of the most important issues of current physics relates to the presence of cosmological cold dark matter (CDM). In this paper CDM at the Galactic centre is modelled using a previously reformulated type of dynamic Newtonian advanced gravity (DNAg). This DNAg gives results which are technically exactly the same as the general theory of relativity (GTR), in the low and medium mass densities. However, in the high mass densities of supermassive black holes, it predicts a dynamic increase in the force of gravity, which explains the apparent presence of CDM at the galactic centre, and at the cosmological level. Thus on the galactic and cosmological mass scales, these equations allow the apparent presence of CDM to be modelled, and accurately calculated. These dynamic Newtonian advanced gravitational equations also offer readily testable gravitational predictions.
