Planck length

Even in existing particle physics it is generally assumed that the traditional simple continuum description of space must break down at least below about the Planck length Sqrt[ℏ G/c3] ≃ 2 × 10-35 meters—since at this scale dimensional analysis suggests that quantum effects should be comparable in magnitude to gravitational ones.
