Hi- Between the Planck particle and the Quark, these is a sizeable relative difference of about 10^15, or in other words and size unit, as if there were no objet whose size would stand between ours (about 1.70 m) and Antares... this is not only about vaccum (or void) in absolute term but also about potential fill rate between these two units of measure. My questions: Why such a void between 10^-35 and 10^-20? Why not between two other size limits? Does any other object exist between these Quark and Plank particle? Thanks !
