“There is a hole in the universe.

It is not like a hole in a wall where a mouse slips through, solid and crisp and leading from somewhere to someplace. It is rather like a hole in the heart, an amorphous and edgeless void. It is a heartfelt absence, a blank space where something is missing, a large and obvious blind spot in our understanding of the universe.

That missing something, strange to say, is a grasp of nothing itself. Understanding nothing matters, because nothing is the all-important background upon which everything else happens.”
