Cosmological billiards [PDF]

open access: yesClassical and Quantum Gravity, 2003
It is shown in detail that the dynamics of the Einstein-dilaton-p-form system in the vicinity of a spacelike singularity can be asymptotically described, at a generic spatial point, as a billiard motion in a region of Lobachevskii space (realized as an hyperboloid in the space of logarithmic scale factors). This is done within the Hamiltonian formalism,

Comparison of the relationship between cosmology and political thought in ancient Iran and ancient Greece. [PDF]

open access: yesرهیافتهای سیاسی و بین المللی, 2020
We know that political thought in Iran and the West has grown in two different contexts. In Iran, political thought is in the context of religious cosmology and in the West, in the context of philosophical cosmology.

The concept of fractal cosmos, I: Anaxagoras’ cosmology [PDF]

open access: yesSerbian Astronomical Journal, 2001
The concept of a fractal cosmos occupies a prominent position in the modern cosmology. We trace the development of this concept from the presocratic Greece to the present state of affairs.

Modular cosmology

open access: yesPhysical Review D, 1995
An exploratory study of the cosmology of moduli in string theory. Moduli are argued to be natural inflaton fields and lead to a robust inflationary cosmology in which inflation takes place at the top of domain walls. The amplitude of microwave background fluctuations constrains the dynamics responsible for inflation to take place at a higher scale than

Emergent cosmology from matrix theory

open access: yesJournal of High Energy Physics, 2022
Matrix theory is a proposed non-perturbative definition of superstring theory in which space is emergent. We begin a study of cosmology in the context of matrix theory.

Precision cosmology, Accuracy cosmology and Statistical cosmology [PDF]

open access: yesProceedings of the International Astronomical Union, 2014
AbstractThe avalanche of data over the past 10-20 years has propelled cosmology into the “precision era”. The next challenge cosmology has to meet is to enter the era of accuracy. Because of the intrinsic nature of studying the Cosmos and the sheer amount of data available now and coming soon, the only way to meet this challenge is by developing ...

Higgs cosmology [PDF]

open access: yesPhilosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2018
The discovery of the Higgs boson in 2012 and other results from the Large Hadron Collider have confirmed the standard model of particle physics as the correct theory of elementary particles and their interactions up to energies of several TeV. Remarkably, the theory may even remain valid all the way to the Planck scale of quantum gravity, and therefore

From Reductionism to Contextualism: L. Wittgenstein and the Dimensions of Modern Cosmology [PDF]

open access: yesФилософия и космология
This article offers a consideration of potential ways to apply the methodology of the philosophy of everyday language to solve modern problems of cosmology and the philosophy of cosmology. Modern cosmology emerges as an independent scientific discipline,

When misinterpreting the Bible becomes a habit

open access: yesHTS Teologiese Studies/Theological Studies, 2018
Ancient Near Eastern (ANE) texts should be interpreted against the background of the magico-mythical cosmology of their time, and the Bible is no exception.

Cosmological observatories [PDF]

open access: yesClassical and Quantum Gravity
Abstract We study the static patch of de Sitter space in the presence of a timelike boundary. We impose that the conformal class of the induced metric and the trace of the extrinsic curvature, K, are fixed at the boundary. We present the thermodynamic structure of de Sitter space subject to these boundary conditions, for static and ...
