The universe formation by a space reduction cascade with random initial parameters

TL;DR

This paper explores universe formation through a cascade of dimensional reductions from a multidimensional Lagrangian, showing multiple initial conditions can lead to the same low-energy physics, thus broadening the understanding of universe origins.

Contribution

It demonstrates that different initial parameters in a multidimensional framework can produce identical low-energy constants, reducing the emphasis on a unique initial Lagrangian.

Findings

Multiple sets of initial parameters yield observed low-energy physics.

A large landscape of low-energy vacua is generated.

Different initial conditions can lead to the same universe characteristics.

Abstract

In this paper we discuss the creation of our universe using the idea of extra dimensions. The initial, multidimensional Lagrangian contains only metric tensor. We have found many sets of the numerical values of the Lagrangian parameters corresponding to the observed low-energy physics of our universe. Different initial parameters can lead to the same values of fundamental constants by the appropriate choice of a dimensional reduction cascade. This result diminishes the significance of the search for the 'unique' initial Lagrangian. We also have obtained a large number of low-energy vacua, which is known as a 'landscape' in the string theory.
