Default Four questions (with answers)

So you think, like Dawlish, that the radiation from a cold object will not cool a warmer one?


Yes. That is an absurd proposition.

Take the cold object. It is cold but it is still cooling. It does this
by radiating energy. That which you call 'cold' radiation. This
radiation (which contains thermal energy from the cold object) then
strikes a hot object. Your proposition is that the thermal energy that
radiation contained from the cold object simply evaporates into
nothingness, taking with it some of the thermal energy from the hot
object.

This is a direct contradiction of the Law of Conservation of Energy.

Imagine a universe that contains only two objects. A cold one and a hot
one, that are fairly close to each other. Both objects will cool by
radiating energy. My position is that if you increase the distance
between the objects, both objects will cool quicker. If you remove one
object, the other object will cool quicker.
