Theory:Doctor Who television discontinuity and plot holes/A Christmas Carol: Difference between revisions

:::: This isn't actually correct, as Rose touching her infant self ''does'' create a paradox. (''NOTE: Rose never actually touches her infant self in'' [[Father's Day (TV story)|Father's Day]].) I propose a different explanation: the TARDIS can alter or stabilise paradoxes that are expected (presumably, the Doctor has taken active precautions for this). The main support for this theory is that the Doctor is actively messing around with Kazran's timeline, but there are no side effects of this (the changing of Kazran is intentional, thus not a side effect). The interior of the TARDIS is not present for most of the episode in [[TV]]: ''[[Father's Day (TV story)|Father's Day]]'' after an unexpected timeline change when Rose prevents her father's death. In [[TV]]: ''The Big Bang'' the two versions of Amy have a different personal history with the lack of stars. (It's implied that Young Amy can still see them and is questioned by psychiatrists about them, which doesn't occur in the original timeline; also, it's not known whether her original meeting with the Doctor occurs in this timeline.) This is why she can touch her younger self (because they are people with the same genetic makeup, but different personal histories). This also explains why the Blinovitch Limitation Effect does occur with the Sonic Screwdriver, as it's an inanimate object, it does not have an alternate timeline.

:::: When the two Brigadier's touch the effect is an explosion. When the two sonic screwdrivers touched in the previous episode it created a small spark. Therefore the effect seems to vary so it is possible the discharge is so small it is hard to see.
