Black Holes

[Hugh]

Recently I've been toying with the idea that black holes have a limit to how much matter can go into a black hole.

Can anyone tell me if there has been any research into this idea and what they found out?

Thanks.

From what I could tell doing a quick internet search, there doesn't seem to be an upward theoretical limit to a black hole's mass, only a lower limit (about 4 solar masses). There are probably supermassive black holes at the center of active galaxies (including ours) with masses billions of times greater than our sun's.

I know, people gripe about wikipedia, but this article seems to be pretty solidly researched and referenced.

People complain about Wikipedia? I wea reading where they found fewer errors in Wiki than they found in the Encylopedia Briticanica.

As far as the black hole theory, everything I know about black holes I learned from the movie (http://imdb.com/title/tt0078869/)

Thanks for the quick reply. The wikipedia article is interesting but in what I have read so far doesn't cover theories on an upper limit. I'll do a thorough internet search when I have the time. Thanks.

Hey Hugh,

A clarifying question--are you referring to an upper limit of the matter that collapses on itself as the black hole is forming or a limit to the matter that is drawn into a black hole by its massive gravitational force?

I think he was wondering what the critical mass is before the black hole ceases to draw in matter. I fear there is no limit, my theory is ultimately the universe will end with several super massive black holes colliding then sploding in a big bang.....Circle of Life :idea:

I guess I'm just that knowledgable about mass, having not been a Catholic and all.

Everything I know about black holes I learned...
Never mind.

Belize, right?

Black hole. Application of a thought experiment applied to infinity. Gravity in this thought is no different than a constantly accelerating elevator. A clock at the floor of the elevator runs faster than one at the top.

I guess that means I should move to the mountains.

[minorwork]

Nobody caught that? The sun was in my eyes.

Of course the clock on the floor runs slow. Light in the high gravitation near the math structure called a black hole is measured by the clock with it. Relative to us, the clock is so slow that light is trapped in TIME.

I'll be leaving the mountains now.

"Big Al" Einstein did not believe black holes existed in reality.

The thing about Black Holes is that they're not holes. There isn't a 'space' thet gets filled up with matter. AFAIK there's no upper limit.

My God. It...It......Can't beeeeeeeeeeeeeeeeeeeeeeeee.

nice.... obviously there was no practical upper limit on that black hole...

And isn't it odd that you won't see a black hole? an electron? a perfect vacuum? Philosophical concepts all.

What else could explain the things seen where a black hole is postulated to exist? If stars were not fusion powered but electric powered by vast currents flowing through plasma trapped by the pinching of Birkland currents well then the data seen in those areas can be explained in a commonly understood electric explanation.

See a bit more explanation in the literature topic thread: There Are No Electrons.
