摘要：

The Wheeler-DeWitt equation for a closed Friedmann universe allows one to impose an (intrinsic) symmetric initial condition (SIC!) at the "big brunch" (the superposition of big bang and big crunch). All degrees of freedom are essentially absent close to this singularity. They enter existence through states of low excitation.
