I understand how the Planck length (1.6 x E-33 cm) is calculated from the equation ,Gh/( 2πc3), but how is the Planck density calculated at E-5 gm/Planck volume (E93 to E94 gm/cm3). It is based on "energy jitters".(adsbygoogle = window.adsbygoogle || []).push({});

Also, is there an explanation for the vast difference between the observed cosmological constant (E-29 gm/cm3) and calculated value, a difference of E123? Thanks
