The 17 pages that link to Loop quantum gravity, each with the reason it gives.

• Quantum gravityCompared with: Unlike string theory, it seeks to quantize spacetime geometry without adding extra dimensions.

• String theoryCompared with: It pursues quantum gravity through a different route and does not require string theory’s extra dimensions.

• GravitonCompared with: It does not require gravitons as fundamental particles in the same way perturbative gravity does.

• Quantum field theory in curved spacetimeCompared with: It directly quantizes geometry, unlike quantum fields on a fixed curved background.

• Edward WittenCompared with: It offers a distinct approach to quantum gravity from the string-theoretic program Witten helped shape.

• Superstring theoryCompared with: It pursues quantum gravity without superstring theory’s unification framework.

• Theory of everythingCompared with: It seeks quantum gravity but does not, by itself, unify the Standard Model interactions.

• Modern physicsCompared with: It offers a distinct route to quantum gravity from string theory.

• History of general relativityCompared with: Its unresolved relationship to general relativity highlights the challenge of reconciling gravity with quantum physics.

• Quantum foamCompared with: It gives geometry a specific discrete structure rather than relying only on Wheeler’s foam image.

• Hypothetical particle physics modelsCompared with: It addresses quantum gravity by a route distinct from adding new particle sectors.
