The Hartle Hawking wave function of the universe has a ground state that describes the amplitude for a universe to appear from nothing. http://www.drees.nl/publications eng/Interpretation of the wavefunction.pdf The WDW-equation addresses a high energy wave function in the evolution of the universe, and so the question is the identity of the low energy condition for that wave function. A universe coming from nothing as a ground state would still involve a high energy physics, would it not, if it was concerned with the initial condition of the universe? I see a problem here, concerning either one of the concepts in how the wave function is treated. You cannot have a high energy wave function describing the evolution of the universe when high energy physics are only concerned with the beginning and geometry is concerned when the universe has sufficiently cooled - equally, you cannot have a wave function govern a ground state if the initial state of the universe is a high energy phenomenon, if that wave function in equality is a high energy phenomenon... How is that a ground state? I am confused.
For instance, the WDW equation has a problem in finding the low energy condition - the condition associated with almost all of the universes history, when it has cooled down and geometreogenesis prevails. But the Hartle Hawking wave function deals with a ground state condition for the initial set-up of the universe, which does not make sense. Anyone?
I feel no one can answer this. Perhaps the wave functions description of the ground state is actually a law of most action?
