Where is the inside of the Tardis? Is it a world in itself? Is it part of a different world?
The Doctor's TARDIS is larger on the inside than on the outside. How can this be achieved?
The conventional answer is that
The TARDIS is dimensionally transcendental ... the interior exists in a different, relative dimension to the exterior.
However this seems to be gobbledygook. It's a lot of technical sounding words with no real scientific basis.
Note: I am not asking about the time-travel aspect - just how a container could be bigger on the inside than on the outside.
Question
What real science could go some way to explaining how the Tardis can be bigger inside than out?
My main solution so far is.
The Tardis has a built-in portable wormhole. When you step inside, you have entered a real normal-size space in a different part of the universe. Maybe this space exists in a bunker on some planet. The problems are (a) how do you make a wormhole portable and (b) how would the Doctor cope if someone on the other planet attacked the bunker?
Can anyone come up with a better explanation? It needs to be based at least a little in real science. No magic is allowed or shrinking of atoms. As far as I know these aren't genuine scientific concepts.

I would say it's a bit of independent space that's "glued" to ordinary space at the entry door. That also explains how time travelling works: That independent space is "unglued" from space, and then "glued" again to space at another time.
The rest of the police box is just a bit of camouflage in ordinary space to hide the glueing (because otherwise it would look quite strange; not to mention that accidentally walking into the glueing position from the side might turn out deadly because your body gets cut in half).
