In a previous question about the side of the TARDIS interior no actual answer to the size of the interior of the TARDIS could be found. And at the Battle of Canary Wharf we see the Genesis Ark as what looks like at least several thousand Daleks emerge from it, even though it doesn't look big enough to hold more than one Dalek.
I know we can't answer this question on our own, but there's decades of Doctor Who canon, so I'm wondering if someone may have heard something about this somewhere along the line.
Is there a limit, in Timelord technology, to how large an interior of a container can be compared to the exterior size of the container? If there isn't an absolute limit, is there any kind of practical limit, such as how much power it takes to create the larger interior or to maintain the connection between the interior and the exterior?
