Is the Universe Really So Simple?

The intriguing suggestion of Tegmark (1996) that the universe---contrary
to all our experiences and expectations---contains only a small amount of
information due to an extremely high degree of internal symmetry is
critically examined. It is shown that there are several physical
processes, notably Hawking evaporation of black holes and non-zero
decoherence time effects described by Plaga, as well as thought
experiments of Deutsch and Tegmark himself, which can be construed as
arguments against the low-information universe hypothesis. In addition, an
extreme form of physical reductionism is entailed by this hypothesis, and
therefore any possible argumentation against such reductionism would count
against it either. Some ramifications for both quantum mechanics and
cosmology are briefly discussed.
