Many-Particle Quantum Cosmology

TL;DR

This paper explores a novel quantum cosmology approach where the universe is modeled as a bosonic string tachyon, analyzing its thermodynamics and monodromy in Fock space.

Contribution

It introduces the Many-Particle Quantum Gravity framework, treating the universe as a tachyonic bosonic string groundstate, and discusses related thermodynamics and monodromy problems.

Findings

Universe modeled as a tachyonic bosonic string groundstate

Analysis of thermodynamics of the universe in this framework

Discussion of the extremal tachyon mass model

Abstract

The Einstein-Friedmann Universe as whole quantum object can be treated as bosonic string mass groundstate, called a tachyon, having negative mass square and a speed more than the speed of light. I present a brief review of results obtained from this point of view called Many-Particle Quantum Gravity approach - the monodromy problem in the Fock space, thermodynamics of the Universe, and the extremal tachyon mass model.
