Main Question or Discussion Point
Good morning. Not sure if I am doing this right, but I just wanted to ask a question.
It can of course increase in mass over time by objects crashing into it. But, that can happen to a star as well. In any case, the mass remains finite.So the mass doesn't increase over time, and if it's the same mass of the star that created it, how does it have an event horizon or the same gravitational "footprint" as the star that created it?
