With the introduction of multiply connected topologies into physics, a question of causality arises. There are alternative routes between two points in a multiply connected space. Therefore, one may ask if a signal traveling at the speed of light along one route could be outpaced by a signal which has traveled a much shorter path through a handle o...

... Initially, the idea of "bridges" was considered more attractive than that of black holes until Wheeler and Fuller showed that the Einstein-Rosen bridge 1 is unstable. Using a proper analysis, they discovered that the bridge would pinch-off in a finite time [6]. Therefore, Schwarzschild wormholes are not traversable. ...
