Lee Smolin Quote

There is a smallest unit of space. Its minimum value is given by the cube of the Planck length... If you take a volume of space and measure it to a very fine precision... It has to fall into some discrete series of numbers, just like the energy of an electron in an atom.... we can calculate the discrete areas and volumes from the theory.
