The Biggest Thing in Space

So, what’s the biggest thing in space?  A galaxy is pretty big, but it’s really a collection of a lot of things.  A star is one solid mass, but -- huge as it is -- it’s really small compared to a black hole.  At least, when you measure mass, not volume, which you should always do, since mass affects gravity.  That brings us to the largest thing that exists -- the thing that everything else in a galaxy orbits -- a Supermassive Black Hole.  These mega-black holes are the mass of millions of stars, sometimes billions or sometimes even greater numbers!  Recently, astronomers got to see a Supermassive Black Hole being knocked clear out of its galaxy.  Experts believe it may have collided with another SMBH at really high speed!  (article here)
