I think this was one of Shrodinger's thought experiments or supposed paradoxes. It might have been referred to as "Shrodinger's Oven".

I think my Fractal Foam Model of Universes has a solution, but I am ignorant of what the supposed problem is.

In case you're wondering, the solution is that there is an energy equivalent of space, so the expansion of space acts as an infinite heat sink.
