Absolute zero is maybe possible but we can't tell for sure because it would not register on the black body curve...which is what is used to get the radiation/temp of off stars and planets and such.
As for the opposite...when a star collapses the core goes from hydrogen to helium then I think silicon and stuff and finally to iron...now that can get to be 300 mil K in temp...which is damn hot...but no matter what can any energy be produced because iron cannot do thermonuclear fusion

How is that just the lab expoeriments on earth will verify everything that going on in black holes and other galaxies? What if there is a parallel universe, or a negative of this universe where things. I guess these are just my philoshopical question. (damn it, we do not have a ophilosophy forum yet.😞 )
a black hole is the penomenon known as singularity: a point in space so dense(infinite density) that it curves the time-space to infinity. in result, time-space ceases to exist. so you cannot discuss what properties "notimespace" has in another universe.
even if another universe has different properties eg different nuclear force values, once you pass event horizon of a black hole you are identically screwd in all imaginable universes

I was just pointing out that we know so little. The examples might have been a little dramatic. 😛
I still argue that we cannot know answer to the question though.

some we can guess. educated guess. so if you are asking if frogs can fly,we can safely say that they cannot even if we haven't seen all the frogs in the world and we don't know whether there is one that does fly(the greeks thought of this dilemma)
so with i a little logic i made the affirmation that a black hole behaves the same no matter what the laws of physics are. feel free to argue with me 😀

Why?
It would be possible, but overwhelmingly staistically unlikely to happen. Probably the chances of it happenning are lower than all the particles in the universe.

You mean the ratio of the inverse of all the particles in the universe?
Is Absoulte Zero possible...
