  The finite age of the universe and the existence of cosmological horizons
provides a strong argument that the observable universe represents a finite
causal region with finite material and informational resources. A similar
conclusion follows from the holographic principle. In this paper I address the
question of whether the cosmological information bound has implications for
fundamental physics. Orthodox physics is based on Platonism: the laws are
treated as infinitely precise, perfect, immutable mathematical relationships
that transcend the physical universe and remain totally unchanged by physical
processes, however extreme. If instead the laws of physics are regarded as akin
to computer software, with the physical universe as the corresponding hardware,
then the finite computational capacity of the universe imposes a fundamental
limit on the precision of the laws and the specifiability of physical states.
That limit depends on the age of the universe. I examine how the imprecision of
the laws impacts on the evolution of highly entangled states and on the problem
of dark energy.
