I've read that the Big Bang is sometimes referred to as the "Big Cool," since it is likely that the early universe cooled very suddenly, and thus expanded rapidly. I've also read that the entropy of the universe is always increasing (ok, that's obvious), and as entropy increases the average temperature of the universe is increasing. For some reason, I thought I read somewhere that these two facts were related...did I dream this? I am not posing a theory, or it would be in that section... I was just wondering if anyone has read an article linking these two facts, or something similar. If not, just say "Nope, you're crazy." Thanks.
