The emergence of our Universe

TL;DR

This paper proposes a novel theoretical framework where our Universe emerges from symmetry breaking in a multicomponent algebra related to Jordan algebras, potentially explaining cosmological observations through a modified Friedmann equation.

Contribution

It introduces a new model linking algebraic symmetry breaking to Universe emergence and cosmological expansion, extending previous theories with Jordan algebra structures.

Abstract

We show how our Universe can emerge from a symmetry breaking of a multicomponent $W_3$ algebra, where the components in addition form a Jordan algebra. We discuss how symmetry breaking related to the Jordan algebras $H_3(C)$ and $H_3(O)$ over the complex and octonion numbers can lead to an extended four-dimensional spacetime, where the expansion of the Universe is governed by a modified Friedmann equation. We finally discuss how this modified Friedmann equation might explain a number of puzzling cosmological observations.
