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."
Textbook by Misner, Thorne and Wheeler. Written in 1972, this tome is black with a diagram of an apple being examined under a magnifying glass on the front cover. It is 1279 pages of unrelenting formalisim. I have dipped in and out of this test but have yet to cast myself afloat in it's waters. This book is almost singlehandedly responsible for the resurgance seen in research in gravity in the last quater century.

Grav"i*ta"tion (?), n. [Cf. F. gravitation. See Gravity.]


The act of gravitating.


(Physics) That species of attraction or force by which all bodies or particles of matter in the universe tend toward each other; called also attraction of gravitation, universal gravitation, and universal gravity. See Attraction, and Weight.

Law of gravitation, that law in accordance with which gravitation acts, namely, that every two bodies or portions of matter in the universe attract each other with a force proportional directly to the quantity of matter they contain, and inversely to the squares of their distances.
