Solution to the Cosmological Constant Problem from Pre-geometric Gravity

TL;DR

This paper proposes a pre-geometric gravity framework where spacetime emerges from symmetry breaking, naturally explaining the small cosmological constant through topological quantization and quantum stability without fine-tuning.

Contribution

It introduces a novel pre-geometric gravity model that links spacetime emergence, topological quantization, and the cosmological constant problem in a unified dynamical framework.

Findings

The cosmological constant is quantized into discrete sectors.

The observed vacuum energy is naturally selected by symmetry-breaking.

The vacuum state is stabilized against quantum tunneling by a large potential barrier.

Abstract

We present a novel solution to the cosmological constant (CC) problem that requires no fine-tunings nor anthropic reasoning. In pre-geometric gravity (PGG), spacetime emerges from the spontaneous breaking of a fundamental gauge symmetry. This mechanism dynamically generates general relativity while also revealing a deep connection: the topological Gauss-Bonnet coupling of the theory scales precisely as the de Sitter entropy, an enormous number which reflects the information content of our universe. This coupling acts as a gravitational $\theta$-angle parameter, forcing the CC to become quantized into discrete topological sectors. The symmetry-breaking dynamics naturally selects the sector corresponding to the observed vacuum energy. The selected vacuum state is stabilized by the extremely large potential barrier of the pre-geometric Higgs field, which effectively seals it off from quantum tunneling transitions to other topological sectors. The PGG framework thus provides a dynamical explanation for the smallness of the CC, linking gravity, topology and quantum information in a unified picture.
