• Gravity or gravitation is a natural phenomenon by which all things attract one another including stars, planets, galaxies and even light and sub-atomic particles. Gravity is responsible for the formation of the universe (e.g.
  • Gravity is most accurately described by the general theory of relativity (proposed by Albert Einstein in 1915) which describes gravity, not as a force,
  • Gravity is the weakest of the four fundamental interactions of nature. The gravitational attraction is approximately 10−38 times the strength of the strong force (i.e.

    Definition of gravity in English Dictionary

  • NounPLgravitiesPREgravi-SUF-ity
    1. Resultant force on Earth's surface, of the attraction by the Earth's masses, and the centrifugal pseudo-force caused by the Earth's rotation.
      1. It is tempting to speculate about the incentives or compulsions that might explain why anyone would take to the skies in [the] basket [of a balloon]: perhaps out of a desire to escape the gravity of this world or to get a preview of the next; […].
    2. Gravitation, universal force exercised by two bodies onto each other (In casual discussion, gravity and gravitation are often used interchangeably).
      1. Some of the most beautiful and thus appealing physical theories, including quantum electrodynamics and quantum gravity, have been dogged for decades by infinities that erupt when theorists try to prod their calculations into new domains. Getting rid of these nagging infinities has probably occupied far more effort than was spent in originating the theories.
    3. The state or condition of having weight; weight; heaviness.
      1. Specific gravity.
        1. The state or condition of being grave (graveness).

            • We find new restrictions on the Hilbert space of pure gravity by imposing invariance under large diffeomorphisms and normalizability of the wave function.

          2. Used in the Beginning of Sentence
            • Gravity waves, while predicted by theory for decades, have been notoriously difficult to detect.
