# A Bi-directional Big Bang/Crunch Universe within a Two-State-Vector Quantum Mechanics?

@article{Bopp2018ABB, title={A Bi-directional Big Bang/Crunch Universe within a Two-State-Vector Quantum Mechanics?}, author={Fritz Wilhelm Bopp}, journal={Foundations of Physics}, year={2018}, volume={49}, pages={53-62} }

A two boundary quantum mechanics incorporating a big bang/big crunch universe is carefully considered. After a short motivation of the concept we address the central question how a proposed a-causal quantum universe can be consistent with what is known about macroscopia and how it might find experimental support.
