- W2964274071 abstract "The null geodesic congruence for the Lorentzian version of Hawking’s wormhole is studied in spherical Rindler coordinates. One finds that the wormhole throat, where the stress energy is mostly located, expands exponentially and that the flare-out condition is satisfied. A time reversal is equivalent to an inversion applied to the radial coordinate. Far from the throat (the light cone in Cartesian coordinates, the negative energy density acquires an expression similar to that of the Casimir energy density between two perfectly reflecting plates. We conjecture that the light propagation follows the throat of a pre-existing expanding wormhole (a light dragging phenomenon)." @default.
