It is deeply connected to the concept of information theory, particularly the idea that the universe's fundamental building blocks might be bits of information rather than traditional particles or fields. 94: 333:, all of which are central to current physical theories. Moreover, existing models of digital physics violate various well-established features of 782: 515: 652: 500: 433: 265: 603: 203: 185: 123: 70: 152: 105: 357: 56: 806: 269: 801: 604:"Quantum randomness: if there's no predeterminism in quantum mechanics, can it output numbers that truly have no pattern?" 98: 775: 698:"A Discrete Analog of General Covariance -- Part 2: Despite what you've heard, a perfectly Lorentzian lattice theory" 348:
Despite these challenges, covariant discrete theories can be formulated that preserve the aforementioned symmetries.
