One either has to accept that there is no minimum length or time, or one needs to modify special relativity theory! And yes one need to modify SR, point particles is hypothesis that makes little logical sense! ( Please read Principia, Newton would never have bought into it).
Does Special Relativity Lead to a Trans-Planckian Crisis?
My maximum velocity formula brings back a minimum spatial dimension, that indeed is the Planck scale!
wish i could have shown Max my Max velocity formula, to get his critics, but a bit to late, so the closest i can get is to show Max's original signature to my formula..
