I PROPOSE to give some answer to the two questions raised by Sir James Jeans, which so clearly summarise the present state of the problem of the evolution of the universe. I will begin with the second question, because I think that its solution may throw some light on the first one: “Is the universe expanding at about the rate indicated by the spectra of the nebulæ”, the atomic constants not being modified by some artificial change of gauge? I add these words, because it is clear that any… 
83 years of general relativity and cosmology: progress and problems
This paper considers the evolution of the relation between gravitational theory and cosmology from the development of the first simple quantitative cosmological models in 1917 to the sophistication
Better Appreciating the Scale of It: Lemaître and de Sitter at the BAAS Centenary
In September 1931, a panel discussion was convened at Central Hall Westminster on the subject of the ‘evolution of the universe’ at the centenary meeting of the British Association for the
The Relativistic Electron Pair Theory of Matter and its Implications for Cosmology
Although atomic and nuclear physics have made enormous advances during the last century, there has been an increasing crisis in fundamental physical theory with regard to the nature of the ultimate
Implications of Extended Models of the Electron for Particle Theory and Cosmology
Although quantum theory has been very successful in the mathematical description of molecules, atoms and atomic nuclei, it has failed to resolve the conceptual problem posed by the wave-particle
Phenomenological tests of modified gravity
The main goal of this thesis is to test the viability of some modified theories of gravity suitable to describe gravitational phenomena at cosmological and astronomical scales. In the first part of
Cosmic Radioactivity and the Age of the Universe, 1900–1930
During the latter part of the nineteenth century a famous controversy raged in Britain concerning the age of the Earth. On the basis of thermodynamical calculations, Lord Kelvin (William Thomson)
Study of General Relativity and $f(R)$ Modified Gravity with Cosmological Constant for Einstein and Jordan Frames
This thesis investigates a toy model for inflation in a class of modified theories of gravity in the metric formalism. Instead of the standard procedure -- assuming a non-linear Lagrangian $f(R)$ in
To the World
This article provides a comparison of the Hypersphere World-Universe Model (WUM) with the prevailing Big Bang Model (BBM) of the Standard Cosmology. The performed analysis of BBM shows that the Four
Cosmological consequences of theories of modified gravity
Our theoretical understanding of the dynamical evolution of the Universe has certainly improved during the recently established era of precision cosmology. However, the nature of the dark sector
