How do big objects get into the TARDIS?
Have you ever wondered how a big object gets into the TARDIS?
The front doors are perfect for people to get into and out of the TARDIS, but they're not very practical for moving large objects into it.
I'm guessing the TARDIS simply materializes around large objects. Let's say a new TARDIS console is necessary. I would say the operator simply teleports the TARDIS around the new console to where it needs to go.
Of course, if a TARDIS needs a new console, how do you operate it to get it to materialize around a new console? But, let's not think too deeply. :)
