Are we living in a bidirectional big bang / big crunch universe? — •Fritz Wilhelm Bopp — Universität Siegen, Walter-Flex-Str. 3, 57068 Siegen

The interrelation of macroscopic classical and usually microscopic quantum physics is considered. Arguments for fixed two state vector quantum mechanics are outlined in a somewhat pedagogic way. A heuristic concept is developed how something like classical physics could emerge in an early epoch of a finite universe with a compact initial state and an extremely extended final one. The concept contains no intrinsic paradoxes.

However it can not incorporate free agents which are somehow essential. To allow for free agents the fixed final state is replaced by a matching state of maximum extend between an expanding and a contracting universe. How a bidirectional macroscopic world with possible free agents could emerge in such a big bang / big crunch universe is the central object of the paper.
