"Physicists posit that all physical systems store information merely by existing, and can process that information through dynamic evolution over time; by that reasoning, the universe is capable of computation. Physicists are extending that theory to black holes, based on their suspicion that information can escape from these stellar phenomena. A black hole's computational ability stems from information's quantum-mechanical nature, and a black hole's total memory capacity is proportional to the square of its computation rate. This notion dovetails with the holographic principle, which states that the maximum data storage capacity of any region of space appears to be proportional to its surface area rather than its volume. The practical operation of a black hole computer entails the encoding of data as matter or energy, sending it down the black hole--which performs the computation programmed into the data--and then capturing and deciphering the hole's Hawking radiation output with a particle detector. The exactitude with which the geometry of spacetime can be measured is limited by the same physical laws that govern the power of computers. This precision turns out to be lower than physicists used to think, which implies that the size of discrete "atoms" of space and time is bigger than anticipated. With these principles, it can be postulated that the universe is performing a kind of self-computation, computing all matter--from the smallest quantum fields to the most expansive galaxies--and thus mapping out its own spacetime geometry to the highest precision permitted by physical laws.
