Answer: Since this is an infinite universe, all knowledge is potentially available through any source. Potentially, you could learn everything you want to know from a paper cup. Getting into the right state of mind to communicate with a paper cup is the tricky part. Getting the information you want from your Ku, through all your filters of fear and doubt, would be the tricky part, too. If often takes less energy, less time, and less trouble to get information from someone who already has it (or at least some version of it).
