Obviously this song is about SATAN. For god's sake it's like blatantly obvious. Every line works if its SATAN.
The black hole sun is the anti-thesis of a white sun. So, you could say the black hole sun is representing opposites, in this case, the opposite in tradition to white is black with black representing evil and white representing good. By extension to this logic the black hole sun being the opposite of white sun represents the opposite of good, ie Jesus, most likely referring to SATAN ie the anti-christ. Basically it's a call for the apocalypse to occur.
