Re: Cooling issues

Stu, consider yourself corrected.

There is no such thing as "cold", only absence of heat, so for an object to cool off, it has to transfer its heat to something else. On Earth, heat can be transferred to the air. That's how most of our cooling systems work. In space, heat has nowhere to go (no atmosphere), so cooling issues become much more complicated.
