Digital physics is a family of speculative proposals in philosophy, holding that the universe is at its most fundamental level digital, informational or computational in character: that physical reality is either the output of a computer program or is itself a computational process. This metaphysical position is also known as pancomputationalism. The hypothesis that the universe is a digital computer was first set out by Konrad Zuse in a 1967 paper and in his 1969 monograph Rechnender Raum ("Calculating Space"). The term "digital physics" was coined in 1978 by Edward Fredkin, who taught a graduate course under that name at MIT and later came to prefer the label "digital philosophy". Fredkin's collaborations with Tommaso Toffoli and Norman Margolus on reversible and conservative logic made MIT's Information Mechanics group the principal early institutional home of the programme. Digital physics is not a single theory but a cluster of positions that differ over what is claimed to be discrete...
