From NYT: Biggest Black Holes Yet

www.nytimes.com...

One of these newly surveyed monsters, which weighs as much as 21 billion Suns, is in an egg-shaped swirl of stars known as NGC 4889, the brightest galaxy in a sprawling cloud of thousands of galaxies about 336 million light-years away in the Coma constellation.

It seems like every time you turn around, a larger black hole has been discovered. Has there ever been any therories on how big a black hole could get

Mods please move this to the proper forum.

Considering black holes are theory, I could theorize that their size isn't finite. I assume the more mass they consume the larger they become, but, again, theory.

I thought black holes were pretty much proven? Their physics and mechanics maybe be theoretical, but the idea they exist i believe is a fact.

Theyve seen the one in e middle of our galaxy. Of course they havent seen it directly, they have seen stars of enormous size whipping around an unknown objects at tremendous speeds. What else would it be besides a blackhole?

The reason I'm asking about how large a black hole can become is because I'm wondering if a "critical mass" point has been proposed where the mass or densisty has become so great some type of chain reaction occurs.

Doesnt a black hole have the same mass as the star that formed it, that it doesnt change? I believe that if a black hole had infinite mass, you'd be in a black hole right now since it would have infinite gravity.

Wouldn't the material falling into the black hole cause it to accumulate more mass, or is ALL of the material ejected from the black hole?

My guess.... is that a black hole can get as big as the object before the Big Bang.

As we havent observed it directly it could be absolutely anything. The fact that black hole theory has to be amended almost every time a new piece of data is collected makes it more probable (IMO) that a black hole is in fact not at the centre of our galaxy.
