Exact Classical Correspondence in Quantum Cosmology
  We find a Friedmann model with appropriate matter/energy density such that
the solution of the Wheeler-DeWitt equation exactly corresponds to the
classical evolution. The well-known problems in quantum cosmology disappear in
the resulting coasting evolution. The exact quantum-classical correspondence is
demonstrated with the help of the de Broglie-Bohm and modified de Broglie-Bohm
approaches to quantum mechanics. It is reassuring that such a solution leads to
a robust model for the universe, which agrees well with cosmological expansion
indicated by SNe Ia data.
