Zack McCurrie

The largest, most dense object in the known universe more commonly known to it's discoverers as Zack McCurrie. It has a gravitational pull 10x the average black hole's and is thought to be the centre of the universe, the thing that binds all galaxies, nebulas and lone planets to have ever existed in an eternal swirl of all matter.

Holy sh*t that's Zack McCurrie, I didn't even know it was real!
