The Doctor has explained things far better in his previous incarnations so unless the very nature of the universe got change thanks to The Pandorica Opens the Doctor is still spouting nonsense.Rocketboy1313 wrote:Maximara, I don't see the contradiction.
Especially when you throw in the quirk that Smith's Doctor tends to under explain things via analogy, "It's nothing like that, but if that helps."
To take an example, in Genesis of the Daleks the Time Lords wanted the Doctor to avert the creation Daleks from existing or "affect their genetic development so that they evolve into less aggressive creatures."
But the Doctor had met Daleks in his three previous incarnations so the "avert their creation" idea was nonsense out of the gate and the Doctor knew exactly how aggressive the Daleks were so that idea was also nonsense.
In the previously mentioned Day of the Daleks the Doctor is brought to the 22nd century where he is told that Auderly House blew up killing the peace delegation Sir Reginald Styles had set up. This incident falls into "once you know history you're a part of that history and thats a fixed timeline" nonsense and yet the Doctor was able to change it.
DALEK: The Daleks have discovered the secret of time travel. We have invaded Earth again. We have changed the pattern of history.
But to do that the Daleks would have to know history and therefore wouldn't be able to change history.
I should point Day of the Daleks actually names this limitation and how it works.
JO: I just don't understand. I mean, why don't they go back to September the 12th if that's where they want to be. You know, have another go.
DOCTOR: Ah, that's the Blinovitch limitation effect.
Father's Day gives us more information on what happens if you do cross your own timeline and change things.
However, The Waters of Mars shows that small changes can be made without the mess seen in The Wedding of River Song happening.
