Black Hole Gravitational Physics and Dark Matter Modelling as Predicted by Dynamic Advanced Newtonian gravity (DNAg)Dr Andrew Worsley The general theory of relativity (GTR) has been enormously successful in describing gravity. However, some problems remain with gravity, not least that dark matter (CDM) is not explained. There are also infinite singularities in black holes. Additionally there appears to be infinite time dilation at the event horizon, which means that matter cannot enter the black hole in the lifetime of the Universe. Here we deconstruct the equations used in the formulation of GTR. This gives a dynamic form of Newtonian advanced gravity termed DNAg, which resolves a number of problems in gravity. Firstly, it obviates the infinite density singularities, and it does not offer infinite time dilation at the event horizon. By the same token it is possible to explain the presence of dark matter at the centre of the galaxy and in the galactic halo, and the presence of cosmological dark matter as a whole. Moreover, it is corroborated in neutron stars, including data from gravitational radiation damping and is corroborated by black hole studies. Importantly, it offers future predictions for black hole physics, which will be readily testable using the Square Kilometre Array and the Event Horizon Telescope (EHT). Andrew has had a lifelong interest in physics, but originally qualified in medicine in
1979. Subsequently he passed a higher qualification in medical training and
also received a PhD equivalent in molecular genetics. More recently his interest
has turned back to Physics and he has gained a Diploma in Astronomy and become
a Fellow of the Royal Astronomical Society. He has since published several papers in international journals on gravitational physics, Black holes, and Dark matter. The lecture will be followed by a drinks reception for the Friends in the Library.
