Wormholes supported by pure ghost radiation
arXiv:gr-qc/0202059 · doi:10.1103/PhysRevD.65.124016
Abstract
Traversible wormhole space-times are found as static, spherically symmetric solutions to the Einstein equations with ingoing and outgoing pure ghost radiation, i.e. pure radiation with negative energy density. Switching off the radiation causes the wormhole to collapse to a Schwarzschild black hole.
