Query: An intricate quantum statistical effect and the foundation of quantum
  mechanics   An intricate quantum statistical effect guides us to a deterministic,
non-causal quantum universe with given fixed initial and final state density
matrix. A concept is developed on how and where something like macroscopic
physics can emerge.
  The concept does not allow to incorporate philosophically indispensable free
will decisions. If the quantum world and its conjugate evolve independently one
can replace both fixed final states by a matching common one. This allows for
external manipulations done in the quantum world and its conjugate which do not
otherwise alter the basic structure.
  In a big bang / big crunch universe the expanding part can be attributed to
the quantum world and the contracting part to the conjugate one. The obtained
bi-linear picture has a number of beautiful and exciting consequences.
