Gravitational waves and colliding black holes

DTLR has been dormant for nearly a half-year.  However a significant discovery has been reported recently that is worthy of note.  The LIGO (Laser Interferometry Gravitational-Wave Observatory) detected the emission of gravitational radiation from a source event that appears to be the collision of two black holes.  The event marks the dawn of the age of gravitational wave astrophysics.  We are again grateful to be witnesses to the making of physics history.  Congratulations to the LIGO and VIRGO collaborations.
