Time at the origin of the Universe: fluctuations between two possibilities

TL;DR

This paper explores a novel idea that fluctuations in the metric signature near the universe's origin could explain its nonsingular birth, building on Hawking's Euclidean origin concept.

Contribution

It introduces the concept of metric signature fluctuations at the universe's origin as a potential mechanism for a nonsingular beginning, extending Hawking's Euclidean approach.

Findings

Metric signature fluctuations are possible near t=0.

Such fluctuations could lead to a nonsingular universe birth.

The idea offers a new perspective on the universe's initial conditions.

Abstract

A variation of Hawking's idea about Euclidean origin of a nonsingular birth of the Universe is considered. It is assumed that near to zero moment $t = 0$ fluctuations of a metric signature are possible.
