For all of the BlackStar haters, a Black Hole is a Black Star. Yes, it is a star. Its matter is so sense that it has the ability to curve light. It appears to be black because it takes in all of the light around it. A black hole is a star because it contains all of the elements a star needs. You just can't see it.
Anywho, why not go with Blackhole? This way, the physics nubs will compromise.
