The Primordial Particle Accelerator of the Cosmos

TL;DR

This paper explores the theoretical possibility of superluminal particles within certain spacetime metrics, suggesting they could influence early universe conditions and potentially replace inflationary models.

Contribution

It introduces a model for superluminal particles in Euclidean metrics and discusses their implications for early universe thermodynamics and cosmology.

Findings

Superluminal particles are theoretically allowed in Euclidean metrics.

Such particles could enable rapid early universe expansion without inflation.

Euclidean metrics may exist temporarily in the early universe.

Abstract

In a previous paper we have shown that superluminal particles are allowed by the general relativistic theory of gravity provided that the metric is locally Euclidean. Here we calculate the probability density function of a canonical ensemble of superluminal particles as function of temperature. This is done for both space-times invariant under Lorentz symmetry group, and for space times invariant under an Euclidean symmetry group. Although only the Lorentzian metric is stable for normal matter density, an Euclidian metric can be created under special gravitational circumstances and persist in a limited region of space-time consisting of the very early universe which is characterized by extremely high densities and temperatures. Superluminal particles also allow attaining thermodynamic equilibrium at a shorter duration and also suggest a rapid expansion of the matter density, thus making mechanism such as inflation (which demands invoking and ad-hoc scalar field) redundant. This is in accordance with Occam's razor.
