Relativistic Gravity

Recent astronomical discoveries -- quasars, pulsars, gravitational waves, cosmic microwave radiation — reveal that relativistic gravitational effects are of great importance in our Universe. Unfortunately, we do not now have a firm experimental basis for deciding which relativistic theory of gravity is correct: Einstein\u27s general relativity theory, the Brans-Dicke scalar-tensor theory, or some other theory. However, space technology will make possible a number of high-precision experimental tests in the next decade
