An intelligent machine might come up with a new theory of cosmology, and perhaps no human will be able to understand or articulate that theory. Maybe it will refer to non-visualizable dimensions of space or nonintuitive understandings of time. The machine will tell us that the theory makes good predictions, and if nothing else we will be able to use one genius machine to check the predictions of the theory from the other genius machine. Still, we, as humans, won't have a good grasp on what the theory means and even the best scientists will grasp only part of what the genius machine has done. It would be like trying to explain the Periodic Table of Elements to a five-year-old. Maybe it can be done, but it will hardly serve as an easily grasped, intuitive understanding of what is going on.
