Indeed, Seth Lloyd and Jack Ng are proponents of the idea of a discrete
universe. If the universe is discrete, then most models of
hypercomputation are meaningless, something that I believe would make
computationalists really happy. In addition, in a discrete universe there
is practically no free will as Wolfram advocates in his latest book (A New
Kind of Science, Wolfram Media, 2002). Now, on the other hand, Roger
Penrose in his latest book, entitled "The Road to Reality : A Complete
Guide to the Laws of the Universe", gives some really interesting ideas
regarding the discrete nature of energy. And finally, one should not
forget that there is no experimental evidence in favor of the granularity
of space and time!
