Phys. Rev. D 79, 024030 (2009) [10 pages]Simple analytic model of wormhole formationReceived 27 November 2008; published 30 January 2009 An explicit and simple solution representing the wormhole formation is presented. The spacetime is constructed by gluing the Minkowski and Roberts spacetimes at null hypersurfaces in a regular manner. The parameters in the Roberts solution are required to give the negative kinetic term for the massless scalar field. Although a curvature singularity appears at the moment of the wormhole formation, it disappears instantaneously. This instantaneous singularity is weak in the senses of both Tipler and Królak along radial causal geodesics. © 2009 The American Physical Society URL:
