The bang of a white hole in the early universe from a 6D vacuum state: Origin of astrophysical spectrum

TL;DR

This paper explores how a 6D vacuum state with a white hole influences the early universe's expansion and the resulting inflaton fluctuation spectrum on large scales.

Contribution

It introduces a model where a white hole in a 6D vacuum state drives cosmic expansion and explains the origin of the inflaton fluctuations spectrum.

Findings

Inflaton fluctuations spectrum derived from the 6D vacuum model

White hole's role in early universe expansion elucidated

Connection between higher-dimensional vacuum and observable spectra

Abstract

Using a previously introduced model in which the expansion of the universe is driven by a single scalar field subject to gravitational attraction induced by a white hole during the expansion (from a 6D vacuum state), we study the origin of squared inflaton fluctuations spectrum on astrophysical scales.
