>True. "You know!" was kind of a joke because no one really knows.
What I find fascinating is that black holes are now practically confirmed by observations. Like the star in the center of our galaxy, that goes once every 15 years around an invisible center, estimated at ca. 3 million sun-masses. Since the star comes so close to the invisible center (3 times the distance Sun-Pluto), any alternative to a black hole is practically ruled out.

Difference in opinions hath cost many millions of lives: for instance, whether flesh be bread, or bread be flesh; whether whistling be a vice or a virtue; whether it be better to kiss a post, or throw it into the fire... (from Gulliver's Travels)
