Huge black holes video

Years ago, I worked with producer and director Tom Lucas on a documentary, and last year we made a series of short astronomy videos I blogged about here. Tom's latest endeavor is a partnership with Space.com to create short-format videos about astronomy. The Largest Black Holes in the Universe is the newest of these, and it's pretty impressive. Make sure you hit the HD button! The graphics are very nice. The science is good too! I'll have to take some time (when I get some, someday) to watch the rest.
