Abstract

A new generation of interferometric gravitational-wave (GW) detectors has begun operations. They are rapidly approaching a level of sensitivity such that direct detection of GWs is possible (though not quite probable). A vigorous program of R&D and planned upgrades promises to improve sensitivity to the level that detection is very probable, converting these detectors into astrophysical observatories. In this talk, I give an overview of GW science, describing the basic physics of GWs and motivating their promise for astrophysics.
