Web25 sep. 2015 · we demonstrate the existence of timelike and null geodesics connecting two asymptotic regions of the wormhole, such that the tidal forces in the throat are reasonably small. We discuss bounds on the NUT charge which follow from the Schwinger pair creation and ionization thresholds and speculate that such NUT Web21 jul. 2014 · In terms of these parameters, we compute the conditions for the geodesic to traverse the wormhole, to be reflected by the wormhole’s potential or to be captured on an unstable bound orbit at the wormhole’s throat. These causal geodesics are visualized by embedding plots in Euclidean space in cylindrical coordinates.
