next after black holes

I am not sure what you understand by the term "energized" in relation to black holes. A black hole can be thought of (basically and somewhat inaccurately) as an object so massive that the escape velocity is greater than the speed of light. As a result, not even light can escape its gravitational pull when closer than a certain distance to the 'centre of gravity' of the object which is presumed to be so small that it is called a 'singularity'. Read Wikipedia's explanation here: http://en.wikipedia.org/wiki/Black_hole (you can ignore the math for the moment, perhaps, but eventually you need to get your head round it somewhat). You will notice that there is no mention of a black hole being 'energized'. Perhaps what you are referring to is the point when a collapsing star becomes so massive that light cannot escape and it becomes a 'black hole' or is, to all intents and purposes, invisible except by indirect observation of the behaviour of matter in its vicinity?
