Black holes and gravitational waves in concert - a probe of superstring cosmology

TL;DR

This paper discusses how combining observations of primordial black holes and gravitational waves can test superstring cosmology models, potentially providing evidence for a unified theory of fundamental forces.

Contribution

It proposes a novel approach to use combined gravitational observations to probe superstring-based cosmological models.

Findings

Potential to confirm superstring cosmology through observational evidence.

Highlights the synergy between black hole and gravitational wave observations.

Suggests new avenues for testing fundamental physics theories.

Abstract

Two strands of observational gravitation, one the search for astrophysical evidence of primordial black holes and the other the search for gravitational waves, may combine to provide strong evidence in favour of cosmological models based on superstring theory, the leading candidate for unifying gravity with the other fundamental forces.
