The causality road from dynamical triangulations to quantum gravity that describes our Universe

TL;DR

This paper proposes a causality-guided approach from dynamical triangulations to a quantum gravity theory based on W- and Jordan algebras, explaining universe creation, inflation, topology, and cosmic acceleration without a cosmological constant.

Contribution

It introduces a novel quantum gravity framework derived from dynamical triangulations and causality, incorporating algebraic structures to explain key cosmological phenomena.

Findings

Provides a model for universe creation and inflation

Derives a modified Friedmann equation for cosmic acceleration

Explains universe topology and Big Bang energy origin

Abstract

It is shown how one, guided by causality, starting from so-called dynamical triangulations, is led to a candidate of quantum gravity that describes our Universe. This theory is based on W- and Jordan algebras. It explains how our Universe was created, how cosmic inflation began and ended, how the topology and the geometry of our Universe was formed, and what was the origin of Big Bang energy. The theory also leads to a modified Friedmann equation which explains the present accelerating expansion of our Universe without appealing to the cosmological constant.
