Hierarchy of scales from one small parameter

In this scenario natural simple powers of the small cosmological constant generate the observed hierarchy of physical scales: the ten-dimensional Planck scale goes as lambda^(1/12), the weak scale as lambda^(2/12), the neutrino/dark tower scale as lambda^(3/12), and the Hubble scale as lambda^(6/12), with the fundamental five-dimensional Planck scale reduced from the usual value by about a factor of 10^9 to roughly 10^10 GeV.
