Einstein–Gauss–Bonnet gravity: Is it compatible with modern cosmology?

Is cosmology compatible with blue gravity waves?

A primordial gravitational wave background with positive (blue) spectral index is expected in several nonstandard inflationary cosmologies where the stress-energy tensor violates the null energy condition. Here we show that a sizable amount of blue gravitational waves is compatible with current cosmological and astrophysical data. So far most of the works on parameter estimation from cosmic mic...

Modified gravity and cosmology

Lorentzian Gravity and Cosmology

If a material vacuum exists, with the properties of a superfluid through which already recognized material moves, then it is capable of acting as a universal reference frame and as an intermediary for the production of particle pairs throughout the universe, which as they cool and recombine, become the source of both high-and low-temperature cosmic background radiation, as observed. Moreover, i...

Modern Cosmology and Anthropic

Abstract: The anthropic fine-tuning of the cosmos refers to the claim that the laws of nature, the constants of physics, and the initial conditions of the universe must be set to an enormous degree of precision for life to exist. Three major responses have been offered to this fine-tuning: the multiverse explanation; theism; and the claim that it is just a brute fact that requires no further ex...

Innovate and Modern Modeling in Micro-Finance Structure in Compatible with Islamic Shariah Rules

Micro financing is providing financial services and resources for low-income people to improve their financial situation. In many less developed countries, providing these services for low-income classes was next to impossible due to high interest rates and heavy collaterals and guarantees that banks and other credit institutions demand. Micro financing was used since 1960s as a fundamenta...
