The canonical quantization of the cosmic fluid in the pre-inflationary era: a new kind of Emergent Universe

TL;DR

This paper explores the early universe's origin through canonical quantization of cosmic fluid, proposing a non-singular, emergent universe model that challenges traditional Big Bang theories.

Contribution

It introduces a novel approach to quantum cosmology by applying canonical quantization to the cosmic fluid in the pre-inflationary era, suggesting a non-singular origin of the universe.

Findings

Proposes a non-singular, emergent universe scenario.

Applies canonical quantization to cosmic fluid.

Offers insights into the universe's origin beyond Big Bang.

Abstract

The early phase of cosmic evolution is still a great topic of interest to the cosmologist community. Especially the mechanism behind the origin of the Universe is yet to be resolved. Most people believe in the Big Bang models (singular origin of the Universe), but fewer of the cosmologists support in favor of the non-singular origin of the Universe in their works. These models are based on the standard general theory of relativity. In this work, we have aimed to investigate the nature of the early cosmic evolution from the canonical quantization of the cosmic fluid and importantly to find a probable answer of what the true origin of the Universe is.
