Quantum gravity is the effort to describe gravitational phenomena using quantum principles. It aims to reconcile general relativity with quantum theory in regimes such as black holes, the early universe, and the Planck scale.[1][2]

Quantum gravity: quantum theory of spacetime and gravity.

Conceptual role

This topic lies at the boundary between quantum field theory, relativity, cosmology, and the foundations of measurement. It clarifies what is meant by fields, particles, vacuum, and geometry.[3]

Open questions

The main unresolved issues concern how geometry, vacuum structure, horizons, and quantum states behave when gravitational and quantum effects are simultaneously important.[4]
