Dark Matter As An Integral Part Of An Alternative Gravity Model, Hontas Farmer
Dark Matter As An Integral Part Of An Alternative Gravity Model, Hontas Farmer
Hontas F Farmer
The purpose of this paper is to reconcile observations of dark matter effects on the galactic and cosmological scales with the null results of astroparticle physics observations such as CDMS and ANTARES. This paper will also provide a candidate unified and simpler mathematical formulation for the Lambda CDM model. Unification is achieved by a combination of the f(R) approach, with the standard LCDM approach and inflationary models. It is postulated that dark matter-energy fields depend on the Ricci curvature R. Standard methods of classical and quantum field theory on curved space time are applied. When this model is treated as …

Worlds Without End: The Many Lives Of The Multiverse, Mary-Jane Rubenstein
Mary-Jane Rubenstein
Worlds without End explores the recent proliferation of "multiverse" cosmologies, which imagine our universe as just one of a vast, even infinite, number of others. While this idea has been the stuff of philosophy, religion, and literature for millennia, it is now under consideration as a scientific hypothesis, with wildly different models emerging from the fields of cosmology, quantum mechanics, and string theory. Beginning with the Atomistic and Stoic philosophies of ancient Greece, this book assembles a genealogy of the multiverse, seeking to map contemporary models in relation to their forerunners, and to ask why the proposition has become such …
