I have a bizarre love for the heat death theory, partially because it goes so well with Lovecraft's "And with strange aeons even death may die" in my mind.
I too like it as well but because of a different author and story: "The Last Question" by Asimov [1]. It is a short but a must read (and it is free to read as well). It is one of the most beautiful and optimistic scifi stories. Asimov was and still is so ahead of his time.
