There is little doubt that temperatures of objects or particles in
intergalactic space, and even in interplanetary, i.e moon crater temps
at the poles, for instance, can get close to a few degrees K, after eons
of blackbody radiation with no input.
The speculative point about ZPE being a "prop" for low temps on earth is
that the ZPF itself may have a relevance to the entire local frequency
spectrum, and is a modulating or (de)modulating influence on the
blackbody spectrum. Which is saying that ZPE itself could be tied to
some kind of solar interconnection, not purely "space energy" as is the
typical classification, but not tied in the normally accepted dynamics
of radiation. How can something be blackbody related but not blackbody
dominated?
... hmm, just noticed that this is bordering on political incorrectness.
but essentially the answer could be a lot like the so-called 5th force -
in that there could be a modulation of gravity and/or a modulation of
compreture, which is basically due to oddities in electron acceleration
(as Mills indicates) especially at the extremes. The concept of "virtual
photons" is also interesting if they should become "less virtual" at the
extremes.
