Wormhole geometry from gravitational collapse

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