Testing General Relativity with LowFrequency, SpaceBased GravitationalWave Detectors
Abstract
We review the tests of general relativity that will become possible with spacebased gravitationalwave detectors operating in the ∼ 10^{5}  1 Hz lowfrequency band. The fundamental aspects of gravitation that can be tested include the presence of additional gravitational fields other than the metric; the number and tensorial nature of gravitationalwave polarization states; the velocity of propagation of gravitational waves; the binding energy and gravitationalwave radiation of binaries, and therefore the time evolution of binary inspirals; the strength and shape of the waves emitted from binary mergers and ringdowns; the true nature of astrophysical black holes; and much more. The strength of this science alone calls for the swift implementation of a spacebased detector; the remarkable richness of astrophysics, astronomy, and cosmology in the lowfrequency gravitationalwave band make the case even stronger.
