The central prediction of loop theory is therefore that space is not a continuum, it is not divisible ad infinitum, it is formed of ‘atoms of space’. A billion billion times smaller than the smallest of atomic nuclei. Loop theory describes this atomic and granular quantum structure of space in a precise mathematical form. It is obtained by applying the general equations of quantum mechanics written by Dirac to Einstein’s gravitational field. In particular, loop theory specifies that volume (for example, the volume of a given cube) cannot be arbitrarily small. A minimum volume exists. No space
