Gravitational Wave Astronomy
Waves are one of the most remarkable predictions of Einstein's theory of
general relativity. These waves are ripples in the curvature of spacetime which carry
information about the changing gravitational fields of distant sources.
Although you can generate gravitational waves just by shaking your fist, to
generate gravitational waves strong enough to be detectable with current technology
needs extremely dense, massive objects, such as black holes and neutron stars, and moving
at very high speeds.
By measuring gravitational waves, we hope to learn about systems that cannot be
observed with existing means, such as optical, radio, infrared, etc.
Gravitational waves can penetrate regions these electromagnetic waves cannot,
allowing us to directly observe black holes and other massive objects in the
distant Universe. Since the gravitational waves we will observe are generated
by very strong gravitational fields, precision measurements of these waves will
also allow us to perform unprecedented tests of the general theory of relativity.
