Overview
Advanced view of Quantum Gravity & Extreme Spacetime
General relativity describes spacetime and gravity extremely well on macroscopic scales, while quantum mechanics governs microscopic matter and fields. Quantum gravity is the unresolved effort to construct a consistent theory for regimes where both descriptions are simultaneously essential, such as the earliest universe and deep black-hole interiors.
Quantum-gravity research addresses black-hole interiors, the Big Bang singularity, horizon thermodynamics, spacetime microstructure, and unification of fundamental forces.

Classical spacetime can develop singularities where curvature and density become formally unbounded, signaling breakdown of the classical description.
