Physics:Quantum curved spacetime
Quantum curved spacetime refers to curved relativistic geometry considered together with quantum fields or quantum-gravity questions. In general relativity, mass-energy curves spacetime; in semiclassical physics, quantum fields can propagate on that curved background.[1][2]
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]
