"All objects emit radiation based on their temperatures - scientific fact. If you have two objects then there will be two sets of radiation - common sense. The hotter object will emit hot radiation and the cold object will emit cold radiation - common sense. The hot radiation will warm the cold object and the cold radiation will warm the hot object - simple science."

What is complex about that? It is about as simple as you can get.

If I have a bucket with two differently sized holes in the bottom, would
the water that leaks be called big water and small water? Or just water?

You are right in that there is nothing complex about it, Alistair.
Whether the object is warm or cold it emits radiation.

If you have two objects which are of marginally different temperatures,
the radiation emitted will be identical, save that one object will emit
more of it than the other, so you couldn't cal that radiation warm or
cold as your nomenclature is relative.

It is true, that there are temperature levels, either side of which, the
wavelength of the radiation from any particular material will change but
it is still the same radiation and more so, two objects of differing
material can emit the same wavelength of radiation even though they are
at vastly different temperatures. Are you saying that that radiation is
both warm and cold at the same time?

It isn't complex until you start adding warm and cold to it.
