>All normal (baryonic) matter emits electromagnetic radiation when it has a temperature above absolute zero
So that means normal matter will spotaneously evaporate right?

Eg; if you cooled a very region of space down to near absolute zero, and had say a 1kg cube of iron in it also near absolute zero as low as you can get - it cant go lower, and since it will always be above absolute zero it will emit radiation - that energy will come from somewhere, so basically the iron will start evaporating into photons until its completely gone?
