Inflation as a White Hole explosion from a 5D vacuum

TL;DR

This paper proposes a model where the early universe's inflation is driven by a White Hole explosion derived from a 5D Ricci-flat metric, linking quantum fluctuations to the cosmological constant.

Contribution

It introduces a novel 5D Ricci-flat metric framework to model inflation as a White Hole explosion, connecting higher-dimensional geometry with early universe dynamics.

Findings

Quantum fluctuations are scale-invariant and related to the cosmological constant.

The model links White Hole properties to inflationary expansion.

Effective 4D hypersurface exhibits Schwarzschild-de Sitter geometry.

Abstract

Using a new kind of 5D Ricci-flat canonical metric, we obtain by a static foliation an effective 4D Schwarzschild-de Sitter hypersurface. We examine some particular initial conditions which could be responsible for the inflationary expansion of the early universe, which could be driven by the explosion of a White Hole (WH). The zeroth order spectrum outside the WH describes quantum fluctuations, which for a scale invariant power spectrum, can be expressed in terms of the cosmological constant, or the square mass of the WH.
