general relativity
n.
The geometric theory of gravitation developed by Albert Einstein, incorporating and extending the theory of special relativity to accelerated frames of reference and introducing the principle that gravitational and inertial forces are equivalent.

General Relativity  (jnr-l)
A geometrical theory of gravity developed by Albert Einstein in which gravity's effects are a consequence of the curvature of four-dimensional space-time. According to this theory, the energy and momentum of all matter and radiation cause curvature in space-time, in a way similar to the creation of electric and magnetic fields by electric charges and currents. This curvature also opens the possibility that the universe is closed, having finite volume but without any boundary. Among the many experimentally confirmed consequences of General Relativity are the perihelion precession of the planet Mercury, the bending of light in a gravitational field, and the slowing of time in a gravitational field.

One is the problem of quantum gravity--of how you combine quantum mechanics (which focuses on small-scale phenomena and nongravitational forces) and general relativity (which deals with large-scale objects and gravitational forces) into a coherent picture of nature.
Finally, Eisenstaedt ponders what will become of general relativity as today's physicists search for a unifying theory of the quantum and gravitational domains.
The talk is scheduled on the 100th anniversary of Einstein's introduction of the theory of special relativity, which he refined in 1916 in more complete form as general relativity.
