“The TVC universe will never collapse. Never. A hundred billion years, a hundred trillion; it makes no difference, it will always be expanding. Entropy is not a problem. Actually, ‘expanding’ is the wrong word; the TVC universe grows like a crystal, it doesn’t stretch like a balloon. Think about it. Stretching ordinary space increases entropy; everything becomes more spread out, more disordered. Building more of a TVC cellular automaton just gives you more room for data, more computing power, more order. Ordinary matter would eventually decay, but these computers aren’t made out of matter. There’s nothing in the cellular automaton’s rules to prevent them from lasting forever.

Durham’s universe - being made of the same “dust” as the real one, merely rearranged itself. The rearrangement was in time as well as space; Durham’s universe could take a point of space-time from just before the Big Crunch, and follow it with another from ten million years BC. And even if there was only a limited amount of “dust” to work with, there was no reason why it couldn’t be reused in different combinations, again and again. The fate of the TVC automaton would only have to make internal sense - and the thing would have no reason, ever, to come to an end.”

“Rabbi Heskel Shpilman is a deformed mountain, a giant ruined desert, a cartoon house with the windows shut and the sink left running. A little kid lumped him together, a mob of kids, blind orphans who never laid eyes on a man. They clumped the dough of his arms and legs to the dough of his body, then jammed his head down on top. A millionaire could cover a Rolls-Royce with the fine black silk-and-velvet expanse of the rebbe’s frock coat and trousers. It would require the brain strength of the eighteen greatest sages in history to reason through the arguments against and in favor of classifying the rebbe’s massive bottom as either a creature of the deep, a man-made structure, or an unavoidable act of God.”

“I luv the ded, this old baster sez to me when I wiz tryin to get some innfurmashin out ov him. You fukin old pervirt I sez, gettin a bit fed up by this time enyway, an slit his throate; ah asks you whare the fukin Sleeping Byootie woz, no whit kind of humpin you lyke.”

“There’s a cellular automaton called TVC. After Turing, von Neumann and Chiang. Chiang’s version was N-dimensional. That leaves plenty of room for data within easy reach. In two dimensions, the original von Neumann machine had to reach further and further - and wait longer and longer - for each successive bit of data. In a six-dimensional TVC automaton, you can have a three-dimensional grid of computers, which keeps on growing indefinitely - each with its own three-dimensional memory, which can also grow without bound.

And when the simulated TVC universe being run on the physical computer is suddenly shut down, the best explanation for what I’ve witnessed will be a continuation of that universe - an extension made out of dust. Maria could almost see it: a vast lattice of computers, a seed of order in a sea of random noise, extending itself from moment to moment by sheer force of internal logic, “accreting” the necessary building blocks from the chaos of non-space-time by the very act of defining space and time.”
