Bosonic M Theory

TL;DR

This paper proposes a conjecture that bosonic string theory has a strong coupling limit related to a 27-dimensional theory, potentially providing a stable ground state similar to M theory's relation to superstrings.

Contribution

It introduces a new conjecture linking bosonic string theory to a higher-dimensional theory analogous to M theory, expanding understanding of string theory's non-perturbative regime.

Findings

Conjecture of a 27-dimensional theory underlying bosonic string theory.

Proposal that the line interval becomes infinite at strong coupling.

Discussion of potential implications for string theory stability.

Abstract

We conjecture that there exists a strong coupling limit of bosonic string theory which is related to the 26 dimensional theory in the same way that 11 dimensional M theory is related to superstring theory. More precisely, we believe that bosonic string theory is the compactification on a line interval of a 27 dimensional theory whose low energy limit contains gravity and a three-form potential. The line interval becomes infinite in the strong coupling limit, and this may provide a stable ground state of the theory. We discuss some of the consequences of this conjecture.
