1Massive gravity — In theoretical physics, massive gravity is a particular generalization of general relativity studied by Hendrik van Dam, Martinus J. G. Veltman (1) , and Vladimir E. Zakharov.(2) One assumes that physics takes place in Minkowski space and gravity …
2Double quasar — A pair of quasars may be referred to as a double quasar, if they appear close to each other in the sky. This pairing may result in a chance alignment, physical proximity, actual close physical interaction, or effects of gravity bending the light… …
3Multiply imaged quasar — A multiply imaged quasar is a quasar that is undergoing gravitational microlensing, resulting in double, triple or quadruple images of the same quasar. The first such gravitational lens to be discovered was the double imaged quasar Q0957+561 in… …
4Gravitropism — [or geotropism ] is a turning or growth movement by a plant or fungus in response to gravity. Charles Darwin was one of the first Europeans to document that roots show positive gravitropism and stems show negative gravitropism . That is, roots… …
5building construction — Techniques and industry involved in the assembly and erection of structures. Early humans built primarily for shelter, using simple methods. Building materials came from the land, and fabrication was dictated by the limits of the materials and… …

7Kepler problem in general relativity — The Kepler problem in general relativity involves solving for the motion of two spherical bodies interacting with one another by gravitation, as described by the theory of general relativity.Typically, and in this article, one body is assumed to… …
