(Some) singular solutions are replaced by non-singular bouncing solutions.

(Some) singular solutions are replaced by singular bouncing solutions.

The universe obeys the "DeWitt boundary condition" which requires the wavefunctions to vanish at singularities.

(Some) singularities are resolved by wormholes/topology changes.

Spacetime is fundamentally discrete, and the discrete structure does not contain singularity.

There is no correct theory of quantum gravity (e.g., gravity is not subject to quantum mechanics).

Modified gravitational action (as opposed to Einstein-Hilbert action) prevents singular solutions.

Singularities prevented  by general relativistic time dilation approaching infinity

Resolves when there is widespread consensus that a viable theory of quantum gravity has been found, or when this is proven impossible.
