Howling:RTD fixed points vs. Darvill-Evans fixed points

This probably isn't worth the thought I've put into it, but… I think RTD borrowed the term "fixed point in time" from the NAs, without borrowing its meaning. Am I right?

The original meaning of a "fixed point in time", from the NAs, is this: The "universal present" is somewhere around Rassilon Era 6500; everything before that is the past, and therefore immutable; everything after is the future, and therefore in flux. But time travelers "drag their present" with them. So, when the Doctor visited Perivale in 1989, he created a fixed point that was part of his (and therefore the "universal") present, and is therefore now part of the past, and therefore can't be changed.

The new series completely tossed out the way history worked in the NAs, and even gave us an in-universe explanation: With the destruction of Gallifrey, the Web of Time was replaced by a great big ball of wibbly-wobbly timey-wimey stuff. (The BBC novels had earlier done the exact same thing, except with a different destruction of Gallifrey in a different Time War, and without the word "timey-wimey".)

Nevertheless, the new series (unlike the BBC novels) uses the term "fixed point in time", all the time. Is it the same concept, or even related? For example, the Silence seeing the Doctor get killed at Lake Silencio in 2011 was a fixed point in time, one that the Silence intentionally created. Does that have anything to do with the Doctor dragging his present along to 2011? I can't see any way in which it does.

(By the way, if I'm right that they're completely unrelated concepts, I think the RTD version is a much more interesting one. But that's neither here nor there.) --70.36.140.233talk to me 06:25, September 28, 2012 (UTC)

The RTD version is certainly an interesting one but it makes no sense. 94.72.194.203talk to me 15:41, September 28, 2012 (UTC)

I'm not going to try comparing the two uses of the term "fixed point in time", since I've no knowledge of the NAs. What I will do is ask 94 to explain why he/she thinks the RTD version makes no sense. We don't know a huge amount about the RTD version & we certainly don't know all the fine details of it, let alone how it's related to the Moffat concept of a "still point in time", but there's a substantial difference between "we don't have enough information to make proper sense of it" & "it makes no sense".

Please note: I'm not saying 94's wrong about it not making sense. It's just that the bald statement without explanation doesn't get us anywhere. (There's also the question: How is an idea that makes no sense capable of being interesting?) --89.240.250.160talk to me 20:48, September 28, 2012 (UTC)


 * I agree that the bald statement doesn't get us anywhere. There are a few things that are problematic; I think there are answers for most of them which don't require too much fanwank, but maybe I'm fooling myself.


 * A fixed point can never, ever be changed, but River changed one: It's not that it's physical impossible to change them, just that doing so unravels all of causality, which is something you should never, ever do.


 * All Time Lords can sense fixed points; they're "the burden of the Time Lords", but they're part of the timey-wimey nature of post-LGTW history where there are no Time Lords: He's using the same words for pre-LGTW events that, if pulled on, would tear the Web of Time as for post-LGTW events that would unravel the chaotic ball of timey-wimey, because they feel exactly the same to him.


 * Nobody can sense them but Time Lords, but the Daleks were afraid to touch Adelaide Brooke because she was a fixed point: The Daleks have some technological way to detect them.


 * Captain Jack isn't an event, he's a person: The Doctor is speaking loosely; maybe it's Jack's existence at each moment in time that's fixed.


 * Anything else? --70.36.140.233talk to me 01:55, September 29, 2012 (UTC)
