Origins of dark energy and inflation in semiclosed Friedman model universe are sought by examining the imaginary pair of gravitationary bound Planckeon-Higgs boson composite requiring temperature T~1015K for thermal creation. Inflation is likely to be related to the singular nature of the transition amplitude D(s2) of the Higgs boson obeying PC-and Tsymmetric Klein-Gordon equation, between neighboring points separated by a space like distance s2 = (ct)2 – r2 < 0 in the ultraviolet region outside the light cone, past and future, violating time-symmetry and local causality .
