Oct 26, 2010 - Our physical universe is discrete, finite, unbounded, deterministic and computational. Jan 29, 2011 - Even if we found that space-time is a cellular automaton at some level, it is possible that such a discrete level of structure is merely supervening upon a more fundamental continuous substratum. Apr 11, 2012 - And when they duplicate waves in a discrete system, they often think of something like a cellular automaton (CA) running a discrete approximation to the wave equation. Aug 7, 2013 - Some physicists — most prominently Stephen Wolfram — have proposed that the universe itself is a cellular automaton, that is that its phenomena unfold algorithmically. Zuse published his book Calculating Space, proposing that the physical laws of the universe are discrete by nature, and that the entire universe is the output of a deterministic computation on a giant cellular automaton. Apr 9, 2012 - This of course still leaves open the question whether all this playing around will prove that the universe actually is one big cellular automaton. Here's an example of what I mean. The result for elementary cellular automaton Rule 30, starting from a single black cell, is shown below transcribed in the Scriabin musical scale and using a grand piano. With enough time, you could give a distinct WolframTones composition to every atom in the universe. The cells can be typically in two states on or off. Of contiguous black cells at a certain height and mapping it to a single note played by the same instrument. An answer is provided by Conway's Game of Life, a well known example of two-dimensional cellular automaton that became popular in the 1970's. Nov 4, 2010 - In Andrew Ilanchinski's massive tome Cellular automata: a discrete universe, Ilanchinski. Feb 9, 2014 - A cellular automaton (CA) is an algorithm acting on cells in a grid at discrete time steps. The problem with this, and it's a serious one, is that this theory predicts that all fundamental physical quantities are discrete (as opposed to continuous), and that moreover space and time themselves must be fundamentally discrete.
