Comment on What are the 'real numbers', really?parentComments−jfarmer12yWell, we can and have made the idea of a computable number precise: http://en.wikipedia.org/wiki/Computable_numberIt's not clear whether the universe is computable, however, in the sense that we only find computable numbers in nature. This is kind of an epistemological catch-22, though. How would we know whether this were the case or not?
