1. Information Physics: The New Frontier

At this point in time, two major areas of physics, statistical mechanics and quantum mechanics, rest on the foundations of probability and entropy. The last century saw several significant fundamental advances in our understanding of the process of inference, which make it clear that these are inferential theories. That is, rather than being a description of the behavior of the universe, these theories describe how observers can make optimal predictions about the universe. In such a picture, information plays a critical role. What is more is that little clues, such as the fact that black holes have entropy, continue to suggest that information is fundamental to physics in general. […] http://arxiv.org/pdf/1009.5161v1

[…] it is important to clarify what the problem is not. We are not asking whether the metaphorical interpretation of the universe as a computer is more useful than misleading. We are not even asking whether an informational description of the universe, as we know it, is possible, at least partly and piecemeal. […] We are asking whether the universe in itself could essentially be made of
