Ellis wormhole
Did you know?
WebA massless wormhole called Ellis wormhole was found by Ellis as the simplest wormhole solution of the Einstein equations with a phantom scalar field in 1973 [24] and by Bronnikov in a scalar-tensor theory in the same year [25]. The Ellis wormhole metric is often referred to as the simplest Morris-Thorne wormhole [26, 27]. WebSep 30, 2024 · Whereas static Ellis wormholes possess an unstable radial mode in both four and higher dimensions [16, 31,32,33,34], the inclusion of rotation might stabilize …
WebWe consider the propagation of light along a 3D nanophotonic structure with the spatial shape of a spacetime containing a traversable wormhole. We show that waves experience significant changes of phase and group velocities when propagating along this curved space. This experiment can be realized with state-of-the-art nanophotonics technology. WebSep 1, 2024 · The Ellis-Bronnikov wormhole (4D-EB) [57,58] was constructed separately by Ellis and Bronnikov employing phantom scalar field (a field with negative kinetic term) and is one of the most researched ...

WebOct 26, 2016 · While an Ellis wormhole does not show sign of gravitation because it was specifically constructed to do so, some other wormholes may not be so unforgiving. What a traveller may experience with the curved space-time in the transition zone which creates the dizzying effect is very strong gravitation. So once you get too near to other wormholes ... brown santaevery scene every timeWebare populated by massless Ellis wormholes as conjectured by Abe [25], it is of importance to calculate their observable signatures.
