_Is Quantum Reality Analog after All?_

)
Conventional wisdom says that quantum mechanics is a theory of
discreteness, describing a world of irreducible building blocks.
It stands to reason
that computersÿÿwhich process information in discrete
chunksÿÿshould be able
to simulate nature fully, at least in principle. But it turns out
that
certain asymmetries in particle physics cannot be discretized;
they are
irreducibly continuous. In that case, says David Tong, author of
"_Is Quantum
Reality Analog after All?_
(http://www.scientificamerican.com/article.cfm?id=is-quantum-reality-analog-after-all
) " in the December 2012 issue of
Scientific American, the world can never be fully simulated on a
computer.
That would be a nice confirmation of comp. As I have often insisted
digital physics (the world can be fully be Turing emulated) violated
the consequence of comp which makes necessary the presence of non
computable observable, and even non enumerable spectra.
Digital physics is self-contradictory. It implies comp, but comp
implies the negation of digital physics, so, with or without comp,
digital physics is contradictory.
