If there is a body at x^0 centigrade alone in space; is it emitting:-

radiation,
hot radiation,
cold radiation,
something else ?

What would 99.999999999999999% of physicists' or maybe, engineers say?


I think 100% of engineers and 99% of scientists would say it is emitting
blackbody radiation.

I would say 100% of scientists. None would say that the warmer body is being cooled by 'cold radiation'. Not one. Zilch.

Well 100% of the engineers would say it is being cooled. Might be less than 99% of the scientists. How many do you think would claim, like you, that the warmer body would be made even hotter by an adjacent cold body?

Errrrrr. None, as they understand the second law of thermodynamics. You don't. Simple as that.

Then how many would think it is made cooler?

It cools via net radiation balance. It is not 'made cooler'. **None** would think that because it doesn't happen and can't happen. Cold radiation, by which a colder body cools a warmer one is impossible, as defined by the second law of thermodynamics. Oddly you don't seem able to re-write that law.

The fact that you don't understand this is your problem; no-one else's. All we can do is point it our to you until you learn, or until you disappear from this thread, still ignorant of the physics.
