A wormhole that actually spits out power? Yeah, it’s all about keeping that throat from collapsing. First you need a steady source of exotic matter—negative energy density—like a lattice of particles that repel gravity. Then you’d wrap it in a containment field that prevents quantum fluctuations from tearing it apart, essentially a shield that’s always on and never leaks. The field has to be tuned to the exact geometry so you don’t get a runaway time‑dilation or a causality loop that kills everyone inside. So, exotic matter, a perfect stabilization field, and absolute isolation from external influence. Anything less and you just turn a dream into a black‑hole‑factory.
