The natural
phenomenon of attraction between massive
bodies, and the act or
process of moving under the
influence of this
attraction. Also called
gravity, this phenomenon is described in the
Law of gravitation.
Einstein described
gravitation as a
distortion of
spacetime under the influence of
mass. See also:
general relativity.
Although it is a pretty big thing; according to
Einstein; "gravitation cannot be held
responsible for people falling in
love."
