Vollgrav

Vollgrav is a term that appears in some theoretical and speculative contexts to denote a hypothetical form of gravity that incorporates the full, non-linear structure of spacetime as described by general relativity. It is not part of standard physics nomenclature, and there is no universally accepted definition. When used, the term typically contrasts full, non-perturbative gravitational effects with common approximations such as Newtonian gravity or linearized gravity.

Etymology and usage: The word appears to be derived from the Germanic root voll meaning "full" and grav, an abbreviation of gravity. In Nordic language contexts it is sometimes used informally to mean "full gravity." Because it is not a standard term, its exact meaning can vary between authors.

Conceptual outline: In principle, vollgrav would refer to the complete solution of the Einstein field equations for a given mass-energy distribution, yielding the exact spacetime curvature rather than a simplified potential. In practice, physicists study analogous ideas by using exact solutions (such as Schwarzschild or Kerr metrics) or numerical relativity to capture non-linear effects, rather than adopting a distinct theory specifically labeled as vollgrav.

Applications and context: The term is more common in speculative essays, science fiction, or educational discussions aimed at illustrating the difference between weak-field and strong-field gravity. It is not associated with a specific predictive framework or experimental program.
