The Hole in the Universe

Welcome to the world of cutting-edge math, physics, and neuroscience, where the search for the ultimate vacuum, the point of nothingness, the ground zero of theory, has rendered the universe deep, rich, and juicy. Every time scientists and mathematicians think they have reached the ultimate void, something new appears: a black hole, an undulating string, an additional dimension of space or time, repulsive anti-gravity, universes that breed like bunnies.
