I hate to keep making the same point but… the math of the E-R bridge shows that even if one could create a pair of entangled black holes (ordinary black holes won’t work) the E-R bridge expands faster than C, so nothing can traverse it. Sci-Fi is amusing Cowboys-in-Space stuff, but not the basis for speculating on possible real-world opportunities. Add in the tidal forces associated with closing in on a black hole and you get a series of impossibilities that would require ScriptMagic to overcome. Easy in Hollywood, not so easy in reality.
