Change of Optical Properties of Space under Gravitation Field

TL;DR

This paper explores how gravitational fields influence the optical properties of space, suggesting that in a flat 3D space model, gravity affects the refractive indices without breaking spatial symmetry.

Contribution

It introduces a model where gravitational effects alter space's optical properties without causing anisotropy, expanding understanding of space-gravity interactions.

Findings

Refractive indices of space are affected by gravitation.

Space's symmetry remains intact under spherical gravitational fields.

Relations for optical property changes near massive bodies are derived.

Abstract

It is shown that, in the model of a flat 3D space, the time (i.e., the Hubble or the gravitation constant) plays a role of a spatial property. Gravitation field of spherical central mass does not lead to a lowering of symmetry of the space and appearance of anisotropy. In particular, the relations that describe the changes in the refractive indices of the space treated as an optical medium near the massive spherical body under the influence of its gravitation field have been derived.
