And because space and time are one and the same thing (space-time) then any kind of messing around with space is going to result in some form of messing around with time - which means potential time machines and potentially some form of Visser Collapse or an equivalent.
Going back to the original post on the thread - I'm not sure that it's correct to speak in terms of one or another of these being more or less realistic or plausible or 'hard science' - because they are all essentially different sides of the same coin in many respects. You can differentiate based on what you're wanting to do (and the tradeoffs involved) and the amount of exotic mass-energy required or the stability of the thing you are creating. But I don't think it really makes sense to speak in terms of what is more or less 'hard science'
My 2c worth,

So, if they all violate ANEC, why is it wormholes were chosen for OA?
Would the setting not work just as perfectly without them? Or is there a reason they are more feasible?
