The FTL Superfluid routers are what also transfers your consciousness to your next clone when you get podded… So what are you going to say next, that if podded your dead for good?
As for wormholes - they covered how a wormholer survives… They said when they introduced them, that the signal can travel through outgoing wormholes until it reaches a FTL network transceiver and transfers you through the normal network from there.
I would then assume that the signal can travel through the closed abyssal gates as well, because some link has to stay active for the gates to activate on both sides.
