After doing some reading on the best ways to explain something being "bigger on the inside" a la Doctor Who's TARDIS, preferably without relying on the "tesseract"/higher spatial dimensions explanations, I found a few posts suggesting that the same concepts behind an Alcubierre Drive can be used to expand the volume within a space while contracting/maintaining the regular smaller surface area of it. I think an older comment somewhere on this subreddit even cited this article (I know basically nothing about the math and physics involved here, but from the parts of it written in layman's terms it does seem to be talking about exactly this concept, expanding the interior space of a "bubble" and keeping the spacetime there flat while having the surface area be much smaller).

So a few questions on this concept: first of all, is there any reason to think or reason to NOT think that Alcubierre drive space-expansion could be used for this "bigger on the inside" design? Would it work for an everyday space like a house or other habitation area, or would it be dangerous or disorienting to inhabit/enter an expanded interior volume space, even if spacetime there is flat, without having some sort of protection?

And would the spatial expansion effect be permanent after the drive behind it has performed the expansion, or would there have to be an active supply/maintenance of the effect from whatever technology is creating it, and if it were shut off the space would just revert to normal? (What would happen to the matter, living or otherwise, inside the extra-space then; would it all get destroyed, or just pushed together into the regular-size interior space's area?)

I'm interested in this whole topic and what would be done with it, so answers and general trivia on the matter are very appreciated!
