Can scale-dependent cosmology alleviate the H<sub>0</sub> tension?

چکیده

Scale-dependence is a common feature to all effective models of quantum gravity. In this paper, cosmological model based on the scale-dependent scenario gravity presented. It argued that such models, where scale-dependence appears as correction classical $\Lambda$CDM evolution, have potential addressing tensions between early and late time measurements $H_0$. After defining criteria parametrize tension, we perform numerical scan over parameter space model, subject these criteria. analysis, it found that, indeed, tension can be released.

A scale - dependent cosmology for the inhomogeneous Universe

A scale-dependent cosmology is proposed in which the Robertson-Walker metric and the Einstein equation are modified in such a way that Ω 0 , H 0 and the age of the Universe all become scale-dependent. Its implications on the observational cosmology are discussed.

A Proposed Scale-Dependent Cosmology for the Inhomogeneous Universe

We propose a scale-dependent cosmology in which the Robertson–Walker metric and the Einstein equation are modified in such a way that Ω0, H0 and the age of the Universe all become scale-dependent. Its implications on the observational cosmology and possible modifications of the standard Friedmann cosmology are discussed. For example, the age of the Universe in this model is longer than that of ...

Modifications of the Hubble Law in a Scale-Dependent Cosmology

We study some observational consequences of a recently proposed scale– dependent cosmological model for an inhomogeneous Universe. In this model the Universe is pictured as being inside a highly dense and rapidly expanding shell with the underdense center. For nearby objects (z ≪ 1), the linear Hubble diagram is shown to remain valid even in this model, which has been demonstrated both analytic...

Can mirrors alleviate visual hemineglect?

Following right hemisphere stroke, many patients display an indifference to objects and events in the left side of the world ('neglect'). Here, we describe a new technique that might help accelerate recovery from neglect. The patient sits at a table and a mirror is propped vertically on the patient's right side in the parasagittal plane, so that when the patient rotates his head rightward and l...

S-branes, Negative Tension Branes, and Cosmology

A general class of solutions of string background equations is studied and its physical interpretations are presented. These solutions correspond to generalizations of the standard black p-brane solutions to surfaces with curvature k = −1, 0. The relation with the recently introduced S-branes is provided. The mass, charge, entropy and Hawking temperature are computed, illustrating the interpret...
