The result of the calculation turned out to be that volume really is not a continuous variable; it is discrete, and hence that space is constituted of quanta of volume, or quanta of space. But this is not all: we also realized that these quanta of volume resided exactly on the intersections of the loops. In other words, the volume is composed of quanta, of finite grains of space, and the intersections of the loops represent precisely these grains of space. They are the grains of space we were looking for from the start.
