aside the $C_1$ term in (61), it gives the Hartle-Hawking wavefunction when $V(\phi)=Constant\;=V$. In our earlier work [@bis:prd] we have shown that the normalization constant $N_o$ thus obtained is consistent with Coleman and Klebanov’s [@col:np; @kle:np] arguments and we interpreted the constant $N_o$ as a manifestation of wormhole contribution to the wavefunction.The recent work [@unru:gr-qc] also supports our viewpoint.

Thus we have shown that the initial condition of SWD equation is fixed by the Gaussian anstaz $$\Psi = N (t) e^{- {{\Omega} \over 2} \phi^2}$$ in which a factor $N(t)$ is obtained taking the contributions of repeated reflections between the turning points. This contribution can be interpreted as due to wormhole contributions.

The superposition principle of quantum mechanics requires the existence of repeated reflections and here it is ensured by the presence of turning points. The classical turning point $a={1\over \sqrt{2V}}$ serves as a doorway to keep the universe’s emergence in the classical regime. The quantum turning point $a=0$ acts as an entrance door of all quantum force supposed to arise from the other ensemble of universes.

An intuitive picture is that there is an ensemble of ‘Quantum Universes’ from which our universe tunnels retaining only the quantum property of
