Actually I think it is the rest of you that need to learn science instead of putting on this act like you know when you don't know. Most of your remarks are twisted semantics and nothing more.
A Sun could be considered a black hole for the following reasons:
1. Intense gravity that does not allow or create orbital transits around the Sun but would in fact pull everything to the Sun based on the objects mass. Objects with larger mass might possibly be able to enter into an orbital transit around such a Sun but would have to be extremely enormous in size.
2. An object passing across the Event Horizon of a Sun that due to its smaller mass the object would not be able to escape the gravitational influence of the Sun regardless of how much thrust the object created against the gravitational pull.
3. Black Holes and Stars do occupy each other at the some moment. If a black hole and star did not occupy the same space and time then the star would never have the potential of becoming a black hole.
As shown in the Hertzsprung-Russell Diagram, Main Sequence stars span a wide range of luminosities and colors, and can be classified according to those characteristics. The smallest stars, known as red dwarfs, may contain as little as 10% the mass of the Sun and emit only 0.01% as much energy, glowing feebly at temperatures between 3000-4000K. Despite their diminutive nature, red dwarfs are by far the most numerous stars in the Universe and have lifespans of tens of billions of years.
On the other hand, the most massive stars, known as hypergiants, may be 100 or more times more massive than the Sun, and have surface temperatures of more than 30,000 K. Hypergiants emit hundreds of thousands of times more energy than the Sun, but have lifetimes of only a few million years. Although extreme stars such as these are believed to have been common in the early Universe, today they are extremely rare - the entire Milky Way galaxy contains only a handful of hypergiants.

If a sun therefore does not emit enough energy to keep from collapsing but does not collapse but the pressure against the smaller massed objects orbiting the Sun are pushed towards the Sun from larger massed objects further away from the sun where the smaller massed objects continue a degenerate transit into the Sun followed by the larger massed objects further out that are being pushed into the sun by larger massed objects further away exerting an inward force then the sun can be considered a Solar Black Hole.
This would take place when the orbital transits of the objects involved degenerated in their transits around the Sun that would over time cause the objects to collide with the Sun but would not have the objects spin off into space.
It takes light millions of years to leave the Sun and is not an instant process.
The Universe is a Big Place. As far I know we haven't even left the planet and colonized the Moon yet so to say that everything would be the same in all Galaxies based on how the Milky Way Galaxy is and how the Sol System is rather a degenerate orbit.
