Quantizing a dust-filled universe with positive cosmological constant yields a unitary wave packet whose expectation value bounces, avoiding the classical Big Bang singularity.
This complexity raises questions about the practical con- struction of a unitary quantum theory with this clock choice, though it does not definitively preclude it
