  The case for collapsed objects in some X-ray binary systems continues to
strengthen. But there is now even firmer evidence for supermassive black holes
in galactic centres. Gravitational collapse seems to have occurred in the
centres of most newly-forming galaxies, manifesting itself in a phase of
quasar-like activity (which may be reactivated later). These phenomena
(especially the gas-dynamical aspects) are still a daunting challenge to
theorists, but there is `cleaner' evidence, based on stellar dynamics, for
collapsed objects in the centres of most nearby galaxies. The current evidence
does not tell us the spin of the collapsed objects -- nor, indeed, whether they
are described by Kerr geometry, as general relativity theory predicts. There
are now, however, several hopeful prospects of discovering observational
signatures that will indeed probe the strong-gravity domain.
