[edit] Energy Functional

What is the meaning of the last paragraph, which sets up an energy functional? The n's are not defined anywhere, and the paragraph does not really add anything to the article. —Preceding unsigned comment added by 134.76.215.201 (talk) 13:31, 14 November 2007 (UTC)

It basically says that the expectation value of the Hamiltonian is the energy eigenstates for the Wheeler-DeWitt equation... —Preceding unsigned comment added by 67.166.144.11 (talk) 23:25, 14 December 2007 (UTC)
