Research ArticleOpen accessIn the keywordsGravity, the Origin of the Mass in the CosmosFrancisco Pavía Alemany, Marcelino Alvarez VillarroyaThe most accepted theory for the evolution of the Cosmos is the Big Bang theory, which suggests that, at the beginning, the entire mass-energy of the Cosmos was concentrated within an extremely small, dense and hot singularity. Here, we present a new physical formula that, although obtained in an extremely simple way, has significant implications in Cosmology. This equation indicates … …Physics International, Vol. 12, Issue 1 · 28 Oct 2021 · 9,391 accessesView PDFCite
Research ArticleOpen accessIn the keywordsGravity. Origin and Quantum Evolution of the CosmosFrancisco Pavía Alemany, Marcelino Alvarez VillarroyaThe most widely accepted hypothesis regarding the birth and evolution of the Cosmos is the Big Bang theory, which states that, before the beginning, all the current mass energy of the Cosmos was already concentrated within an extremely small, dense, and hot singularity. However, in this article, we propose a new model resulting from physical-mathematical deductions and the discovery of … …Physics International, Vol. 16, Issue 1 · 15 Sep 2025 · 5,323 accessesView PDFCite
Review ArticleOpen accessIn the keywordsOn the Generation of Equivalent 'Black Hole' Metrics: A ReviewStephen J. CrothersVarious line-elements purporting different types of black hole universes have been advanced by cosmologists but a means by which the required infinite set of equivalent metrics can be generated has evaded them. Without such a means the theory of black holes is not only incomplete but also ill-posed. Notwithstanding, the mathematical form by which the infinite set of equivalent metrics … …Space Science International, Vol. 3, Issue 2 · 6 Jul 2015 · 13,560 accessesView PDFCite
