The Fabric of Reality is a book by physicist David Deutsch written in 1997. It expands upon his views of quantum mechanics and its implications for understanding reality. This interpretation, which he calls the multiverse hypothesis, is one of a four-strand Theory of Everything (TOE). The four strands are:
His theory of everything is (weakly) emergentist rather than reductive. It aims not at the reduction of everything to particle physics, but rather mutual support among multiverse, computational, epistemological, and evolutionary principles.
According to the many worlds interpretation of quantum mechanics, the total of physical reality is actually a multiverse, consisting of an infinity of universes. Deutsch argues for it on four main grounds:
However:
This emergentist posture allows Deutsch to do some serious work with the Church-Turing thesis (or "Turing principle" as he calls it), which is fundamental in theoretical computer science. In the strong form he favors it implies that a...
