The primary consequence of the computational nature of the universe is that the universe naturally generates complex systems, such as life. Although the basic laws of physics are comparatively simple in form, they give rise, because they are computationally universal, to systems of enormous complexity.
Seth LloydAll physical systems can be thought of as registering and processing information, and how one wishes to define computation will determine your view of what computation consists of.
Seth LloydScience consists exactly of those forms of knowledge that can be verified and duplicated by anybody.
