Seems to have gone quiet here.

Looking at the picture of a pulsing neutrino star and its surrounding system
I wondered if a black hole originally forms from space debris accumulating and then becoming a sun and then a solar system, gradually accumulating mass until it reached a point where the gravity exceeded the ability of light to escape, thence becoming a black hole that would continue on accumulating matter.

This could continue until some unknown point of mass at which a supernova occurs which blows the material outwards and compresses the center and at some point the mass stops moving away and starts falling back in to restart the whole thing over again. The process running over trillions of our years. Somewhat like a heartbeat.

is a very pretty real picture (enhanced) to print twice , stick back to back and hang from your childs bedroom ceiling . Bring out the science fiction/fact bug we all have.
