"Burning Walls" May Stop Black Hole Formation
KentuckyFC writes "Black holes are thought to form when a star greater than 4 times the mass of the Sun explodes in a supernova and then collapses. The force of this collapse is so great that no known force can stop it. In less massive stars, the collapse cannot overcome so-called neutron degeneracy, the force that stops neutrons from being squashed together. Now a Russian physicist says another effect may be involved. He points out that quantum chromodynamics predicts that when neutrons are squashed together, matter undergoes a phase transition into "subhadronic" matter. This is very different from ordinary matter. In subhadronic form, space is essentially empty. So the phase change creates a sudden reduction in pressure, forcing any ordinary matter in the star to implode into this new vacuum. The result is a massive increase in temperature of this matter that creates a "burning wall" within the supernova. And it is this burning wall that stops the formation of a black hole, not just the degeneracy pressure of neutrons. This should lead to much greater energies inside a supernova than had been thought possible until now. And that's important because it could explain the formation of high energy gamma ray bursts that have long puzzled astrophysicists."
I'll have to read the paper to see it this idea addresses this issue.
You run along and do that. Also, have you ever kissed a woman in passion?

Is it just my observation, or is eldavojohn an idiot?
So... our solar system will vanish into a blackhole (in a few million of million of years...)!
That's a sad end...
I can't call that English
how is this modded informative? I swear, I spend all my time just dealing with trolls here these days...
It appears that Bible-humpo nut-freaks are getting a lot of mod points these days. A mild side joke about church-child-molesting got my comment modded as flamebait the other day; and now this post I'm replying to, even though it it on-topic, correct, informative, and insightful.
Hey Bible-humpos, stop the hatin'.
