Theory:Doctor Who television discontinuity and plot holes/Full Circle

You are exploring the Discontinuity Index, a place where any details or rumours about unreleased stories are forbidden.
Please discuss only those whole stories which have already been released, and obey our spoiler policy.

This page is for discussing the ways in which Full Circle doesn't fit well with other DWU narratives. You can also talk about the plot holes that render its own, internal narrative confusing.

Remember, this is a forum, so civil discussion is encouraged. However, please do not sign your posts. Also, keep all posts about the same continuity error under the same bullet point. You can add a new point by typing:

* This is point one.
::This is a counter-argument to point one.
:::This is a counter-argument to the counter-argument above
* This is point two.
::Explanation of point two.
::Further discussion and query of point two.

... and so on. 

• Romana says that the TARDIS weighs 5x10⁶ kilos 'in your gravity' (i.e. 50,000 tonnes), which doesn't really explain firstly how the Marshmen can easily pick it up and also numerous references in other stories (TV: Marco Polo, Army of Ghosts, etc.) to the TARDIS being light enough to be lifted by a group of men.

It is possible that the gravity is different to Earth's or that the TARDIS's mass is variable.

The gravity is clearly similar to Earth's, as everyone moves around just as on Earth and has an Earth-type physique - and water waves are the same shape as on Earth too. It's possible that Romana is referring to the mass of the TARDIS's internal spaces. If the exterior of the TARDIS weighed 50,000 tonnes it would sink deeply into the soil or destroy floors at most of its landing-points - and could not possibly float as seen in Fury from the Deep.

• How did Adric get to the Rebels without passing The Doctor or any Marshmen? And how did the Rebels get back without seeing them?

• When Adric flys the TARDIS by accident he says he must have pulled the wrong lever when he flicked a switch.

That's a pretty trivial difference. Most likely, he either didn't remember whether he pulled one of the many levers or flicked one of the many switches, or he is simply using the terms interchangeably. On an electronic control console such as that of the TARDIS, a lever is basically just a big switch.

• Whilst it is certainly not at all improbable that the inhabitants of another universe would invent similar components (such as image translators) to those invented in N-Space, it seems remarkably fortuitous that they would apparently be made to a universal (no pun intended) "plug and play" design. Unless some very enterprising computer hardware corporation is abusing the CVEs purely for the purpose of broadening its market base, perhaps...
