COSMOLOGY IN ISLAM, CONSTRUCTING ISLAMIZATION OF NATURE SCIENCE

open access: yesJurnal Al-Dustur, 2022
Cosmology is one of the philosophical and scientific objects that become attention in Greek philosophers, especially Aristotle. However, with the times, this cosmology was found in The Qur’an, exactly in the concept of the sky and earth creation which ...

Observational constraints on the fractal cosmology

open access: yesEuropean Physical Journal C: Particles and Fields, 2022
In this paper, we explore a fractal model of the universe proposed by Calcagni (J High Energy Phys 03:120, 2010) for a power-counting renormalizable field theory living in a fractal spacetime.

Extending cosmology: the metric approach [PDF]

open access: yes, 2012
In this chapter it is shown how the introduction of a fundamental constant of nature with dimensions of acceleration into the theory of gravity makes it possible to extend gravity in a very consistent manner.Comment: 2012, Extending Cosmology: The Metric

Classical and Quantum Solutions and the Problem of Time in $R^2$ Cosmology [PDF]

open access: yes, 1995
We have studied various classical solutions in $R^2$ cosmology. Especially we have obtained general classical solutions in pure $R^2$\ cosmology. Even in the quantum theory, we can solve the Wheeler-DeWitt equation in pure $R^2$\ cosmology exactly ...

Post-inflationary brane cosmology [PDF]

open access: yes, 2001
The brane cosmology has invoked new challenges to the usual Big Bang cosmology. In this paper we present a brief account on thermal history of the post-inflationary brane cosmology. We have realized that it is not obvious that the post-inflationary brane

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.

Brane-world cosmology [PDF]

open access: yes, 2006
Brane-world models, where observers are restricted to a brane in a higher-dimensional spacetime, offer a novel perspective on cosmology. I discuss some approaches to cosmology in extra dimensions and some interesting aspects of gravity and cosmology in ...

Topics in Cosmology [PDF]

open access: yes, 2006
These lectures present a brief review of inflationary cosmology, provide an overview of the theory of cosmological perturbations, and then focus on the conceptual problems of the current paradigm of early universe cosmology, thus motivating an ...

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.
