By "action of p_+" what do you mean? Does it make your "quantum jump" occur?

I do not understand this sentence.

If the total state \Psi is an eigenstate of the total Hamiltonian L_0(tot) of
yours, how the "quantum jump" occur? See

L_0(tot) \Psi = 0,

and \Psi is the total state. There is nothing happen. Scattering operator S
of the universe becomes I, the identity operator. No scattering occur. How
quantum jump can exist?

Then you agree that also geometric time does not exist?

In view of the two observation above, there is no psychological time of the
total universe?
