Phenomenological quantum gravity is a research field in theoretical physics and a subfield of quantum gravity.[citation needed]


The objective of phenomenological quantum gravity is to find observable evidence for the quantization of gravity by the development of phenomenological models, which quantify possible quantum gravitational effects and can ideally be tested experimentally. In many cases, predicted effects are too small to be measurable with presently available technology, but examples exist of models which have been ruled out already and others which might be able to be tested in the near future.[specify][citation needed]

The relevance of this research area derives from the fact that presently none of the candidate theories for quantum gravity has yielded experimentally testable predictions. Phenomenological models are designed to bridge this gap by allowing physicists to test for general properties that the to-be-found theory of quantum gravity has. Even negative results are thus useful guides to the development of the theory by excluding possible properties. Phenomenological models are also necessary to assess the promise of future experiments.[citation needed]
