Reconciling Quantum Mechanics and Gravity

Establish a consistent theoretical framework that reconciles quantum mechanics with General Relativity, providing a settled resolution to the problem of quantum gravity and clarifying the interplay of quantum effects with spacetime geometry across all relevant energy scales.

Background

In the introductory discussion, the authors highlight Weinberg’s impact on the development of effective field theories and note their relevance to longstanding foundational challenges, particularly the reconciliation of quantum mechanics with gravity. Despite substantial progress in low-energy descriptions and candidate ultraviolet completions, the definitive resolution of quantum gravity remains unsettled.

This explicit acknowledgment frames the unification of quantum mechanics and General Relativity as a continuing open problem, one that motivates diverse approaches such as effective field theory, string theory, and asymptotic safety, all discussed elsewhere in the paper.
