I've been thinking (OK, OK, I know that's a bad idea but....) we're told a Black Hole (in space) was formed by the collapse of a huge star? Before the collapse, the huge star could be seen? So, if the light from the huge star could have been seen OK then, how is it that after the collapse/explosion/super nova, nothing can be seen? If the gravity of the Black Hole is such that nothing can escape, not even light, how come light could have been seen from the star before it's demise? Surely the gravity from the huge star should have been the same or more powerful when the star was still in existence as a star?
