 Some authors argue that the physical universe is fundamentally computational. The universe itself is a computing system; therefore, everything in it is a computing system too (or a part thereof). Unlike the previous versions of pancomputationalism, which originate in philosophy, this ontic pancomputationalism originates in physics. It includes both an empirical claim and a metaphysical one. Although the two claims are logically independent, supporters of ontic pancomputationalism tend to make them both.
