Black holes and neutron stars are the primary sources of gravitational wave
detectors. My talk will focus on how such observations can be exploited for
testing General Relativity, confirming astrophysical models and answering
questions in fundamental physics. By observing interactions between black
holes we can probe spacetime geometry in the strong field regime. Merging
neutron star binaries should confirm gamma-ray burst models and allow us to
explore the nuclear equation of state. Compact binary sources are standard
sirens but new work has shown that binary neutron star signals are also
standard "spectra", which means that we might soon have a very powerful
tool for cosmography.
