A mass loss of 200 solar masses per year, as has been conservatively suggested if Weber is detecting gravitational waves from an isotropic source at the galactic center, is shown to be incompatible with (1) the existence of old wide binaries, (2) the existence of globular clusters if this loss rate has been constant over the lifetime of the Galaxy, and (3) the observed K-term, even if this loss has occurred only during the last .1 billion years. From the orbit of omega Centauri in the galactic field, its observed mass distribution, and its tidal radius, it is found that an upper limit to the mass loss from a region of approximately 1.3 kpc radius around the galactic center is 1 solar mass per year, averaged over the lifetime of the Galaxy. The alternatives left open by this limit are briefly discussed.
