Answers to questions people are actually asking about life, the universe and everything, taken from Andy Fletcher's answers to questions on Quora (where he has been a most-read writer on more than a dozen different topics) about science, mathematics, Chaos, Complexity, Relativity, Big Bang, Black Holes, Fractals, the universe and cosmology, meaning and purpose, science and faith, religion, the existence of God, and pretty much anything you can think of. The third in a series by the same title.
