The canonical quantization of the cosmic fluid in the pre-inflationary era: a new kind of Emergent Universe (2308.07982v1)

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.
