General Ether Theory and Graviton Mass

TL;DR

This paper extends the general ether theory by fixing cosmological constants, resulting in an oscillating universe that addresses the horizon problem without inflation, and establishes equivalence with other gravity theories involving massive gravitons.

Contribution

It introduces a restriction in general ether theory that leads to an oscillating universe and proves its equivalence to Logunov's relativistic gravity with a massive graviton.

Findings

Universe oscillates due to fixed cosmological constants

Theory is equivalent to Logunov's gravity with massive graviton

Addresses horizon problem without inflation

Abstract

We introduce additional restriction into "general ether theory" - a generalization of Lorentz ether theory to gravity - which fixes the signs of the cosmological constants in this theory. This leads to an oscillating universe, thus, solves the cosmological horizon problem without inflation. We prove the equivalence of the Lagrangian of this theory with Logunov's "relativistic theory of gravity" with massive graviton and a variant of GR with four non-standard scalar fields and negative cosmological constant. We consider the remaining differences between these theories.
