SPECIAL ISSUE: Selected Essays from the Annual Essay Competition of the Gravity Research Foundation 2022
Editor: D. V. Ahluwalia

Abstract

We discuss a new approach to the problem of quantum gravity in which the quantum mechanical structures that are traditionally fixed, such as the Fubini–Study metric in the Hilbert space of states, become dynamical and so implement the idea of gravitizing the quantum. In particular, in this formulation of quantum gravity the quantum geometry is still consistent with the principles of unitarity and also captures fundamental aspects of (quantum) gravity, such as topology change. Furthermore, we address specific ways of testing this new approach to quantum gravity by utilizing multipath interference and optical lattice atomic clocks.

This essay received an Honorable Mention in the 2022 Essay Competition of the Gravity Research Foundation.
