Probing quantum gravity through astrophysical observations

Abstract:

This work is primarily focused on probing quantum gravity through astrophysical

observations based on the theoretical framework of the Nexus Paradigm of quantum

gravity. The Nexus Paradigm is a theoretical framework that is still in development and

offers a different approach to the problem of quantum theory of gravity. In this framework

gravity, Dark Energy (DE) and Dark Matter (DM) are seen as different manifestations of

the quantum gravity. Astrophysical observations offer a unique test bed for gravitational

theories since at large scales gravity is the dominant interaction. The equations of galactic

and cosmic evolution arising from the Nexus Paradigm are tested against astrophysical

observations which include, galaxy rotation curves, black hole observations by the Event

Horizon Telescope and Advanced Ligo gravitational wave observations.
