All these theoretical modeling is all speculative and prone to sheer fantasy. Of all Black stars observed in the universe, no one has ever observed a Worm Hole, even Einstein had to come up with the conclusion that they probably don't exist. We want Worm Holes to exist because it would make space travel a possibility. They talk about Dark Matter and Dark Energy, but no one has ever detected this stuff that a large chunk of the universe is made of. Dark matter/Energy does exist; it just doesn't exist here. Worm Holes do exist, but not in our neck of the woods. What of the multiverse? Do infinite dimensions result in an endless photocopied version of this universe, resulting in infinite versions of you? Nothing exists outside this universe, so we implode creating endless variations of me. We have Dark Matter/Energy tearing the universe apart and worm Holes shallowing the caramel centers of galaxies, and a endless array of me in endless dimensional universes. We would be live an interesting life, if we can prove any of these really exists. So far it only amounts to (good or bad) fiction. Till some one proves, beyond a shadow of a doubt, that any of this exists in reality, you can take it to the Tower of Babylon host it up as a flag and see who salutes. If a Worm Hole swallow's a Black Hole and it gets caught in the middle; would you have to perform the Heimlich Maneuver? What would become of the Black Hole once it is coughed up, out of the Black Hole, or would it come out the other end. It is either barfing of crapping, one way or the other it has to dislodge. One way or the other. One way or the other.
