Triple

Target class: non-perturbative quantum gravity approach
Context triple: [loop quantum gravity, instanceOf, non-perturbative quantum gravity approach]

• A. geometric theory of gravity chosen
  A geometric theory of gravity describes gravitational phenomena as manifestations of the curvature or structure of spacetime itself, rather than as a traditional force acting at a distance.
• B. non-singular black hole model
  A non-singular black hole model is a theoretical description of a black hole whose core avoids the classical spacetime singularity, typically by invoking modified gravity or quantum effects that yield a finite, regular interior geometry.
• C. nonperturbative effect
  A nonperturbative effect is a physical phenomenon that cannot be captured by any finite-order expansion in a small parameter (such as a coupling constant) and instead arises from intrinsically non-linear or exponentially suppressed contributions, like instantons or tunneling.
• D. holographic duality
  Holographic duality is a theoretical principle in physics stating that a gravitational theory in a higher-dimensional spacetime is exactly equivalent to a non-gravitational quantum field theory living on its lower-dimensional boundary.
• E. bridge-like spacetime geometry
  A bridge-like spacetime geometry is a curved spacetime configuration that connects two distinct regions or universes via a narrow, tunnel-like structure, analogous to a bridge linking separate domains.
• F. None of above.
