The quest for the size of the universe in early relativistic cosmology (1917-1930)

open access: yes, 2011
Before the discovery of the expanding universe, one of the challenges faced in early relativistic cosmology was the determination of the finite and constant curvature radius of space-time by using astronomical observations.

UGE, Universo da Gominha Esticada

open access: yesRevista Brasileira de Ensino de Física
Proponho um análogo mecânico unidimensional simples dos modelos de universo tridimensionais da cosmologia relativista moderna. O objetivo principal da proposta é a apreciação apropriada da relação intrínseca entre a lei da Hubble e a homogeneidade dos ...

The Genesis of Relativistic Cosmology

open access: yes, 2017
This chapter highlights the background for the emergence of relativistic cosmology. A specific interpretational issue, which is treated in this context, is the role of Ernst Mach's principle and the first exploration of the cosmological consequences of ...

In the hyperbolic theory of special relativity is space also hyperbolic?

open access: yes
In the hyperbolic theory of special relativity the space of velocities, the kinematic space, is hyperbolic of radius of negative curvature c the velocity of light. Space itself could be either Euclidean or hyperbolic.

Little rip, pseudo rip and bounce cosmology with generalized equation of state in non-standard backgrounds

open access: yesEuropean Physical Journal C: Particles and Fields
The discovery of universe’s late-time acceleration and dark energy has overseen a great deal of research into cosmological singularities and particularly future singularities.

The Idea of Eternity and Modern Relativistic Cosmology

open access: yes, 2007
Here I want to discuss some exciting aspects of modern relativistic cosmology, both classical and quantum, opening new visions of such traditionally theological problems as those of eternity and eternal ...

Applications of cosmological perturbation theory

open access: yes, 2011
PhDCosmological perturbation theory is crucial for our understanding of the universe. The linear theory has been well understood for some time, however developing and applying the theory beyond linear order is currently at the forefront of research in

The expanding Universe: a primer on relativistic cosmology

open access: yes, 2015
Cosmology - the science of the Universe at large - has experienced a renaissance in the decades bracketing the turn of the twenty-first century. Exploring our emerging understanding of cosmology, this text takes two complementary points of view: the ...
