Absolute Max

[Richie Stan]

I think I understand that Absolute Zero is sort of like when all the molecules are all tightly packed (or not oscillating) and not giving of heat. (I may be wrong), If Im close then is there a theoretical Absolute Max when no more heat can be given off? Or can things just keep getting hotter?

Yes, they can just keep getting hotter.

A while back our universe was, (as a necessary condition of extreme temperature?), virtually pure energy (no matter) confined to a very small space (extreme energy density). This must define "maximum temperature" for our universe.

mibn2cweus: maybe, maybe not.
