Quantum resolution of the cosmological singularity without new physics

Understand

We study a quantum Hot Big Bang in the connection representation, with a matter constant of motion m whose conjugate defines time.

• Superpositions in m induce a unitary inner product.
• The wavefunction reveals a resolution of the singularity problem without new physics or supplementary boundary conditions.
• Backtracking in time, the probability peak eventually halts at a maximum curvature, its height dropping thereafter while a symmetric contracting peak rises.
