On Structure and History of Space-time with Variable Speed of Light

TL;DR

This paper explores a variable speed of light within general relativity to address key cosmological problems, finding that it aligns with Newtonian results and resolves issues like flatness and horizon problems.

Contribution

It introduces a variable speed of light into general relativity, providing a new approach that simplifies cosmological problems and aligns relativistic and Newtonian dynamics.

Findings

Cosmological results match Newtonian dynamics.

Flatness and horizon problems are resolved.

No difficulties remain in standard cosmology.

Abstract

We apply the variable speed of light into general relativity in order to solve the problems we met in the standard cosmology. We're surprised to find that, the results from the general relativity in cosmology are exactly the same as those we got from Newtonian dynamics. The relation between the Newtonian dynamics and the relativistic dynamics can be demonstrated with the variable speed of light. With this approach, some problems in the standard cosmology such as the flatness problem and the horizon problem doesn't arise any more. All the cosmological results and the physical results are reasonable and natural. There are no any difficulties in the standard cosmology.
