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.

Web1 dag geleden · We have now everything ready to check the null effec-tive geodesic completeness. Let us start with the radial case, L = 0 in Eq.(16). The result of the numerical inte-gration is depicted in Fig. 2 taking λ = 1 for the effective null geodesics (solid purple) curve. As a comparison, we also depict the corresponding curves for the geodesics WebEq. (7) relies in the fact that finding null geodesics in a KIMET JUSUFI and ALI ÖVGÜN PHYS. REV.
