Benefits of Objective Collapse Models for Cosmology and Quantum Gravity [PDF]

open access: yes, 2013
We display a number of advantages of objective collapse theories for the resolution of long-standing problems in cosmology and quantum gravity. In particular, we examine applications of objective reduction models to three important issues: the origin of ...

On Under-determination in Cosmology [PDF]

open access: yes, 2012
I discuss how modern cosmology illustrates under-determination of theoretical hypotheses by data, in ways that are different from most philosophical discussions.

Type V singularities with inhomogeneous equations of state

open access: yesPhysics Letters B, 2022
Interest in cosmological singularities has remarkably grown in recent times, particularly on future singularities with the discovery of late-time acceleration of the universe and dark energy.

Relativistic Fractional-Dimension Gravity

open access: yesUniverse, 2021
This paper presents a relativistic version of Newtonian Fractional-Dimension Gravity (NFDG), an alternative gravitational model recently introduced and based on the theory of fractional-dimension spaces.

Cosmological analogies, Lagrangians, and symmetries for convective–radiative heat transfer

open access: yesEuropean Physical Journal C: Particles and Fields, 2020
A formal analogy between the Friedmann equation of relativistic cosmology and models of convective–radiative cooling/heating of a body (including Newton’s, Dulong–Petit’s, Newton–Stefan’s laws, and a generalization) is discussed.

CHARLES SANDERS PEIRCE AND THE PLACE OF CHAOS IN THE NEW WORLD ORDER [PDF]

open access: yesFilozofia i Nauka
This article examines the main ideas of the metaphysics of the prominent American logician and philosopher Charles Sanders Peirce. It is shown that a significant part of his „scientific metaphysics” is evolutionary cosmology, characterized, in particular,

First-Order Logic Foundation of Relativity Theories [PDF]

open access: yes, 2006
Motivation and perspective for an exciting new research direction interconnecting logic, spacetime theory, relativity--including such revolutionary areas as black hole physics, relativistic computers, new cosmology--are presented in this paper.

Correspondence between dark energy quantum cosmology and Maxwell equations

open access: yesEuropean Physical Journal C: Particles and Fields, 2019
A Friedmann–Robertson–Walker cosmology with dark energy can be modelled using a quintessence field. That system is equivalent to a relativistic particle moving on a two-dimensional conformal spacetime.
