I read the different style of story The Last Question by Isaac Asimov. I liked it overall, the story confused me at first after the first character switch. I thought it was just another completely separate story, but I figured out it was just different characters to represent the changing universe but the same old problem. I think one of the meanings of the story is a theory of that life is in a huge cycle and it repeats over and over and over again and that it is a non-understandable unbreakable cycle. Another theme is that people can't make life last forever or anything, and that everything has to reach its maximum entropy and there is no reversing it.
