Abstract

In an attempt to find an origin of dark energy it is found that the hypothetical pair of gravitationally bound Planckeon of mass mpl ~ 0.5g and the Higgs boson of masss mH ~ !0-4 mpl creates a negative attractive potential －GmplmH/lpl. The corresponding temperature of thermal creation T ~ 1028K is higher than T ~1027K accepted by the standard inflationay cosmology, but within the asymptotic limit T ~ ∞ interpolated from Hubble's expansion history to the point origin of the Hubble universe.
