2. HumbleEngineer commented 9 years ago on video What Happens When Two Black Holes Collide?
I would like to address an error in the video. No way that black hole has a diameter of 15k light years. The Schwarzschild radius of 170 billion M? is 0.053 light years (~0.1 diameter) not 15000 (just 5 orders of magnitude off). A quick search of Wikipedia http://en.wikipedia.org/wiki/Holmberg_15A
shows that the galaxy core is 15kly, that's not the same as the black hole.
