Are quantum gravity and grand unification inextricably linked?

Determine whether constructing a quantum theory of gravity is intrinsically linked to unifying gravity with the Standard Model forces; provide theoretical or empirical arguments clarifying whether these two problems are separable or necessarily coupled.

Background

The paper distinguishes between developing a quantum theory of gravity and unifying gravity with other fundamental forces, noting uncertainty about their interdependence.

Clarifying this relationship would inform research strategies in high‑energy physics and quantum gravity, including whether progress on one necessarily constrains or enables the other.
