Quantum Gravity & Extreme Spacetime: Advanced Connections

General relativity describes spacetime and gravity extremely well on macroscopic scales, while quantum mechanics governs microscopic matter and fields. Quantum-gravity research addresses black-hole interiors, the Big Bang singularity, horizon thermodynamics, spacetime microstructure, and unification of fundamental forces.
