Hello, I'm a liberal arts type with an interest in wormholes, so bear with my "science". From my readings, there are two (highly theoretically, of course) ways of creating a wormhole: 1. Focus a galactic-level beam of energy/mass at a single point. This will create a naked singularity that would somehow create a twin singularity elsewhere in the universe. A tunnel would exist between these singularities. Then you dump in a massive amount of exotic matter, whose negative mass would largely negate the gravity of the singularities and change them into transversable mouths. 2. Natural wormholes pop in and out of existence at the Planck level. One of these wormholes would be grabbed from this "quantum foam", probably by means requiring a massive amount of energy as well. By focus energy at this wormhole, it grows to a macroscopic size. Although this is not a singularity, it is a heavily dense object because of the massive energy poured into it to inflate it. Now you pour massive amounts of exotic matter to hold it open and prevent it from collapsing in on itself. My questions are: 1. Am I getting these ideas right, or am I off the mark? 2. Is the first method classical? I understand the second is quantum, but is the first classical? 3. In both methods, is the location of the second mouth entirely random? I just don't understand where the second mouth comes from, in either method. Do quantum wormholes and singularities naturally "reach out across the universe" and somehow pair up with a "kindred spirit" (i.e., another singularity or quantum wormhole mouth) randomly. Or would controlling the level of positive energy pumped into it (during inflation) also control how and where the wormhole connects to? 4. For the first method, rather than just creating your own singularity, could you not instead dump a massive amount of exotic (negative mass) matter into an existing Kerr black hole? Dump enough of this matter into it, then it would eventually evaporate, right? Once evaporated, would you not have a ring-shaped singularity that acts like a wormhole then? Wouldn't the exotic matter negate the gravitational pull of the black hole, and in turn destroy its event horizon and make it safe to go through? Again, I understand this is all theoretical, I was just curious if there are any experts out there that could illuminate some of these points that I am struggling with. Thanks!
