We discuss a proposal on how gravitational collapse of a NEC (Null Energy Condition) violating spherically symmetric fluid distribution can avoid the formation of a zero proper volume singularity and eventually lead to a Lorentzian wormhole geometry. Our idea is illustrated using a time-evolving wormhole spacetime in which, we show how a collapsing sphere may never reach a zero proper volume end-state. The nature of geodesic congruences in such spacetimes is considered and analyzed. Our construction is inspired from a recently proposed static wormhole geometry, the multi-parameter Simpson-Visser line element, which is known to unite wormholes and black holes (regular and singular) in a single framework.

Black bounces to traversable wormholes from pure gravity in four and higher dimensions
gr-qc 2026-08 conditional novelty 6.0 of 10

Any static spherically symmetric wormhole or black bounce with a single integration constant can be made the unique vacuum solution of some specially constructed higher-dimensional pure-metric gravity theory.
