Moron Peterson disputes this by simple assertion, but consider:
a warm body loses heat through radiation and gains heat through
radiation...

I realize you have neither the wits nor scientific literacy to
understand what I'm saying, but I'll provide this for those who come to
this forum with a genuine interest in science:

There are at least two kinds of matter in the Universe, usually called
"ordinary" and "dark". What you're describing is correct for ordinary
matter, but not for dark matter, which does not interact with EM (or
interacts so weakly that we can't yet detect that interaction). Thus it
is incorrect to say that _all_ matter emits radiation when it is warmer
than 0K.
