OptionProbability
The universe obeys the "DeWitt boundary condition" which requires the wavefunctions to vanish at singularities.
(Some) singular solutions are replaced by non-singular bouncing solutions.
(Some) singular solutions are replaced by singular bouncing solutions.
(Some) singularities are resolved by wormholes/topology changes.
Singularities prevented by general relativistic time dilation approaching infinity
Modified gravitational action (as opposed to Einstein-Hilbert action) prevents singular solutions.
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).
