Observational constraints on the fractal cosmology
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.

THE COSMOLOGICAL SPACETIME [PDF]
We present here the transformations required to recast the Robertson–Walker metric and Friedmann–Robertson–Walker equations in terms of observer-dependent coordinates for several commonly assumed cosmologies. The overriding motivation is the derivation of explicit expressions for the radius Rh of our cosmic horizon in terms of measurable quantities ...

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

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

DECOHERENCE IN QUANTUM COSMOLOGY AND THE COSMOLOGICAL CONSTANT [PDF]
We discuss a spacetime having the topology of S3×ℝ but with a different smoothness structure. The initial state of the cosmos in our model is identified with a wildly embedded 3-sphere (or a fractal space). In previous work we showed that a wild embedding is obtained by a quantization of a usual (or tame) embedding.

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

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