    • 2013 June 7, David Simpson, Fantasy of navigation”, in The Guardian Weekly, volume 188, number 26, page 36:
      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).
    • 2012 January 1, Michael Riordan, Tackling Infinity”, in American Scientist, volume 100, number 1, page 86:
      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.
  4. Specific gravity.
  5. The state or condition of being grave (graveness).
