In philosophy, the Weyl's tile argument (named after Hermann Weyl) is an argument against the idea of a physical discrete space (where all the distances are multiples of some constant minimum value), by questioning its concept of distance. It says that it is impossible to define a distance function satisfying Pythagoras' theorem (or even, satisfying it only approximately) on a discrete space, and that since it has been verified that the theorem is at least approximately true in nature, physical space can not be discrete.[1][2][3][4] Solutions to Weyl's argument (i.e. arguing that a discrete physical space is not impossible) have already been proposed in the literature.[5]
