Certainly one of the more interesting questions about the universe. Are there properties of the universe that are unknowable? Who knows, maybe a whole class of interactions are so rare or have such low energy we may only ever receive the slightest of hints that they exist. As a programmer, another interesting question involves dimensionless physical constants, such as the fine structure constant. Are these numbers rational? Irrational? Uncomputable? In computing theory, an uncomputable number is one that no finite algorithm given infinite time and storage can produce. Things like Pi and e are computable. Any randomly chosen real number is almost certain to be uncomputable. We may never know if the physical constants of the universe are computable, but I think it would tell us something very fundamental about our universe.
