I did not consider the gauge-free condition. Both are required for charge conservation to occur, and both are violated in intra-universal wormholes (see the end of section V).  By the way, this is a good thing. If it were not true, you could generate infinite charge from a single charged particle by repeatedly passing it through wormhole mouths.  In this formulation, the charge is still the same no matter how many times it’s threaded through the wormhole. RE: Wormholes do not conserve charge - Rynn - 04-09-2019 Interesting. If a wormhole can’t be charged I imagine it can’t be moved with a magnetic field. Given that they also aren’t physical objects you can manipulate with physical tools what anchors a wormhole to a linelayer for transportation?

You can still charge a wormhole by keeping said charge in the throat.  The wormhole doesn’t retain that charge once it has passed into the other asymptotically flat region. RE: Wormholes do not conserve charge - Rynn - 04-09-2019 Ahh I see. Thanks for explaining
