> There is no "minimal distance", rather there is "distance at which our math model does not work". The paper is talking about an other type of minimum distance: minimum measurable distance. It predicts it to be 2*planck time (pg.7): Combining the experimental limits on speed v, force F and action W using the general relation for energy E = F vt = W/t leads to a limit on measurements of time t given by t ≥ √4G~/c5. (10) The five principles thus eliminate instants of time and introduce a minimum time interval, given by √4G~/c5 ≈ 1.1 · 10−43 s, twice the Planck time.
