Horava-Lifshitz Cosmology

TL;DR

This paper explores Horava-Lifshitz cosmology, highlighting its potential to provide alternatives to inflation and avoid singularities in the early universe through modified gravitational equations.

Contribution

It analyzes the cosmological implications of Horava-Lifshitz gravity, proposing it as a viable alternative to standard inflationary models and singularity resolution.

Findings

Early universe features may replace inflation

Theory can potentially avoid cosmological singularities

Modified equations lead to new cosmological dynamics

Abstract

The cosmological equations suggested by the non-relativistic renormalizable gravitational theory proposed by Ho\v{r}ava are considered. It is pointed out that the early universe cosmology has features that may give an alternative to inflation and the theory may be able to escape singularities.
