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.😞 )
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 still argue that we cannot know answer to the question though.

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 😀

...anywhere in the universe? (Absolue Zaro=-273 degrre Celcius or 0 degrees Kelvin-460 degrees Fahrenheit)
Heat means the motion of particles, so is it possible that there's no motion at all anywhere in the universe?
Also another discussion question is "what is the opposite (is there any) of absolute zero?
Discuss.
