From Big Crunch To Big Bang - Is It Possible?

TL;DR

This paper explores the theoretical possibility of a cosmological transition from a contracting universe (big crunch) to an expanding universe (big bang), analyzing the conditions and implications of such a scenario.

Contribution

It introduces a novel discussion on the feasibility of a universe transitioning from contraction to expansion within flat space models.

Findings

Identifies conditions under which a big crunch could lead to a big bang transition.

Analyzes theoretical models supporting such a cosmological scenario.

Highlights challenges and open questions in realizing this transition.

Abstract

We discuss the possibility of a transition from a contracting flat space - big crunch - to an expanding flat space - big bang.
