No, I considered wormholes, but the fundamental predicament concerning the traversability of Einstein-Rosen bridges (wormholes) hinges upon the topological instability of the Schwarzschild metric under standard vacuum fluctuations. Specifically, the maintenance of a non-vanishing throat radius necessitates a violation of the Null Energy Condition (NEC), requiring the deployment of exotic matter characterized by a negative energy density and a sub-zero stress-energy tensor.
Without the preventative intervention of a Casimir-induced repulsive Casimir field to counteract the inherent gravitational flux and subsequent singularity-point convergence, the manifold’s intrinsic curvature would undergo a catastrophic spacetime-pinch-off. This results in a transient geodesic truncation, effectively rendering the Lorentzian manifold non-orientable and inducing a back-reaction of Hawking radiation that triggers an instantaneous event horizon collapse via nonlinear graviton self-interaction. In short, the metric expansion of the throat is stochastically decoupled from the Minkowski background, leading to a quantum decoherence of any baryonic matter attempting to transit the hyperspatial isthmus.
