What is quantum gravity?

Quantum Gravity

Quantum gravity (QG) is the field of theoretical physics which attempts to develop scientific models that unify quantum mechanics (describing three of the four known fundamental interactions) with general relativity (describing the fourth, gravity). It is hoped that development of such a theory would unify all fundamental interactions into a single mathematical framework and describe all known observable interactions in the universe, at both subatomic and cosmological scales.

Famous quotes containing the words gravity and/or quantum:

    Grown beyond nature now, soft food for worms,
    They lift frail heads in gravity and good faith.
    Derek Mahon (b. 1941)

    The receipt to make a speaker, and an applauded one too, is short and easy.—Take of common sense quantum sufficit, add a little application to the rules and orders of the House, throw obvious thoughts in a new light, and make up the whole with a large quantity of purity, correctness, and elegancy of style.
    Philip Dormer Stanhope, 4th Earl Chesterfield (1694–1773)
