Of course, this is all purely hypothetical since no one’s ever seen a wormhole before, but in my story, I have tech that “contains” the entrance to a small wormhole. Wherever the tech goes, the entrance moves with it, kind of like a sort of Marvel—Tesseract thingy. What I want to know is if the math that actually does predict wormholes tells us anything about the frame of reference they might use for positioning the entrance.
For example, if person X opens and stabilizes a wormhole, will the wormhole’s entrance remain motionless from the person’s point of view, the sun’s point of view, or the galactic center, etc? e.g. if it remains motionless from the person’s point of view, it will remain in the room it was created in, but if it remains motionless from the point of view of, say, the sun, it would instantly whiz away from the room it was created in due to the motion of the Earth in its orbit.
I hope that wasn’t too unclear, if you still need clarification, just let me know. Also, I totally get that no one actually knows this for sure, so I’m just asking for speculations here.
