Monster Black Hole Busts Theory

Genocaust writes "A stellar black hole much more massive than theory predicts is possible has astronomers puzzled. Stellar black holes form when stars with masses around 20 times that of the sun collapse under the weight of their own gravity at the ends of their lives. Most stellar black holes weigh in at around 10 solar masses when the smoke blows away, and computer models of star evolution have difficulty producing black holes more massive than this. The newly weighed black hole is 16 solar masses. It orbits a companion star in the spiral galaxy Messier 33, located 2.7 million light-years from Earth. Together they make up the system known as M33 X-7."

Re:Supermassive black holes

[StikyPad]

If theory says that black holes beyond 10 solar masses cannot form, how do they explain the conjectured supermassive black holes

Like This.

Or, more pedantically, black holes may never form at all from the point of view of an observer outside the event horizon.

Computer models of Supernovae

[confused_demon]

For this discussion it's worth keeping in mind that current computer models have real problems actually getting supernovae to explode. At one point it was so bad that I heard someone say, "If it weren't for the fact that we occasionally observe one explode, I would assure you that they cannot." It's only been in the last couple of years that someone has made a computer model that actually did it.
