For some reason, discussion of the laws of thermodynamics seems to be
following me around recently. And of course, my concept of the
“conservation of misery” follows.

So I googled for good defs of the laws of thermodynamics. And
aside from decided that what was once refered to as “the
0th law of thermodynamics” (since a, it was the last one
put into words, but the other two depend on it, and b, cause
it define absolute zero), is now called the 3rd law. “0th law”
was a much cooler name.

But I found an somewhat depressing quote in the process, if
for no other reason, the cold (pun intended) tone it is stated.

From http://www.geog.ouc.bc.ca/physgeog/contents/6e.html

The Universe will attain absolute zero when all energy and matter is randomly distributed across space. The current temperature of empty space in the Universe is about 2.7 Kelvins.
