Description
Traversable wormholes provide a rigorous laboratory for probing the interplay of geometry, matter, stability, and causality in general relativity. This talk centers on the thin-shell formalism: cut-and-paste construction via the Israel-Lanczos junction conditions, precise localization and quantification of exotic matter, and stability analysis. We then examine the geometric characterization of static and dynamical throats, chronology issues, generic thin shells and gravastars, and the black-bounce programme, in which regular black holes and traversable wormholes emerge from a single geometric framework.
