Within Any Possible Universe, No Intellect Can Ever Know It All: Scientific American.
An interesting proof of the ultimate limits of knowledge for any Being within a system. Even a mighty Kardashev Type IV Civilization will face unknowns if trying to operate within the Universe. Of course that does pose the possibility of inter-Cosmic entities linking up multiple Brane-i-verses through the Bulk and knowing them to their fullest extent thanks to their transcendent vantage point. I’m not sure if that’s possible, but it’s as possible as it is not, due to our ignorance of the Bulk and its non-gravitational physics.
