astro picture for the day/ Carl Sagan's first documentary? - The Violent Universe

This is the best science documentary finding since the "Physics and Reality" documentary I posted maybe a year ago or so.  This one goes back to 1969.  It may be Carl Sagan's first appearance in television documentaries as well. I'd say it's his best!

This video documentary captures the realization that the predictions of Einstein's General Relativity - Black holes and the Big Bang cosmology - are real.

Major developments after this video were the x-ray telescopes finding Cygnus X-1 in the 1970s - a black hole in orbit around a star . . . 1983's experimental confirmation of electro-weak unification.  It wasn't till the recent Higgs confirmation and then the detection of gravitational waves that something comparatively big to the Wilson/Penzias experimental discovery/confirmation of the cosmic background radiation.  What could be exciting in the near future?  How about the unification of Quantum Mechanics with General Relativity?

Black holes and the Big Bang cosmology confirm Einstein's General Relativity; they also strongly suggest that quantum mechanics and General Relativity must be combined.  Physicists have recently gotten excited about the the quantum entanglement description of spacetime.  Since, as stated, quantum mechanics and General Relativty must be combined, and quantum entanglement has been confirmed(by Alain Aspects 1980s experiement) and is part of quantum mechanics, then seeing how quantum entanglement relates to General Relativity must bare fruit.
