Of the four fundamental forces, gravity has been studied the
longest, yet gravitational physics is one of the most rapidly
developing areas of science today. This talk will give a
broad brush survey of the past achievements and future prospects
of general relativistic gravitational physics based on the
author's service on the National Research Council's Committee on
Gravitational Physics.  Gravity is a two frontier science being
important on both the very largest and smallest length scales considered
in contemporary physics. Recent advances and future prospects
will be surveyed in precision tests of general relativity,
gravitational waves, black holes, cosmology and quantum gravity.
The aim will be an overview of a subject that is becoming
increasingly integrated with experiment and other branches
of physics.
