TL;DR
This paper proposes a cosmological model based on M-theory, suggesting a pre-big bang scenario driven by assumptions about supergravity, branes, and initial conditions, offering insights into early universe conditions.
Contribution
It introduces a simple M-theory-derived cosmological model with assumptions that naturally lead to a pre-big bang scenario, connecting high-energy physics with early universe cosmology.
Findings
Supports the plausibility of a pre-big bang phase from M-theory principles
Links supergravity and brane dynamics to early universe models
Provides a framework for understanding initial cosmological conditions
Abstract
We discuss a simple cosmological model derived from M-theory. Three assumptions lead naturally to a pre-big bang scenario: (a) 11-dimensional supergravity describes the low-energy world; (b) non-gravitational fields live on a three-dimensional brane; and (c) asymptotically past triviality.
