So, X, you do feel that Gallifrey originally burned? I want to believe that, and it would fix everything if it did, but in the quote Y linked, Moffat does say he decided that it never happened in the first place and The Doctor only thought it did because he couldn't remember (due to future incarnations being there, presumably).
Sorry, went on hiatus from this thread for a little bit. Aaron's done a kick-ass job saying all the things that I would've (and frequently much better and more clearly as he usually does), but I don't think that this's been addressed.
Idgaf what Moffat says in interviews. Anything that's not immediately in the show itself isn't to be trusted, and even things in the show are only somewhat trustable (as Aaron pointed out with
The Impossible Astronaut).
Yes. Gallifrey totally burned at one point in one timeline.
Sorry this is going to be hella long, and overly in-depth about time-travel mechanics, but time travel as a storytelling device is a TINY BIT of a scifi obsession of mine.
Doctor Who isn't like
Looper, where overwriting a timeline completely negates it, but it's also not at all like
Terminator where each timeline just keeps branching out, and people from other timelines step in. It's... something almost inbetween. This is cleared up by having Timelines and Timestreams. A Timeline is just that. It's the shortest point from A to B, or Past to Present. A TimeSTREAM is something that happens when you travel through time, and that's what allows anyone to follow the progression of events that your PERSONAL history took in, through, and around the linear A to B. Easy way to look at it: Lines are straight & efficient, Streams bend and twist.
NOW.
This gets EXCEPTIONALLY messy when you affect your own personal history, because now you're not just making changes to a Timeline, you're also crossing into your OWN TimeSTREAM. This means that if you do it in a way that's too noticeable (because we don't have branching
Terminator-like multiple timelines that prevent this) you can generate a Paradox that can cause any NUMBER of fucked up consequences: see
Turn Left. This is because space-time in Doctor Who has rules to correct itself that manifest in any number of ways, but there are some rules that are explicitly defined:
There are Fixed Points, and Time Locks. Time Locks prevent you from Ctrl+Z'ing your way out of every scenario with Time Travel and especially surrounds particular events that have been HEAVILY FUCKED by excessive time travel through a single point in Space/Time (essentially Izanagi & Izanami in Naruto). This is why New York with the Angels is locked, ditto with the end of the Time War. Essentially everything is too damaged there to keep using time travel as an opt out. Imagine taking a line on a piece of paper and just drawing a loop to direct the line differently, and then undoing that change with another loop. Now keep doing that. When everything starts turning into too much of a mess, that area gets time locked. (Hence why the Doctor almost burned all of Manhattan just trying to LAND the TARDIS in New York in
The Angels Take Manhattan). That's why at some point, the High Council said - if we can't win, and there's no more time traveling to correct it - fuck 'em all, we'll just stop the line here.
Now, Fixed points keep changes fluxuating within a certain degree of the point that you're at. You can still get around that if you're doing something TOTALLY fucked, like collapsing the universe, or blowing up Earth before Pompeii happened or something. Fixed POINTS matter DURING that point. That's why Jack Harkness keeps not dying, because the fixed point of him being alive in each moment of his death happens
in his own timeline so the rule tells his death event to fuck of, and reverses it. Time fixes itself according to at LEAST those set rules. What makes this different from
Looper is how it affects (or rather doesn't affect) the time traveller themselves.
NOW.
DotD starts because there's a trans-spacetime entity (The Moment) who's capable of "bending" these existing rules, but also not. If you don't exist within spacetime in a linear fashion, you aren't limited to traveling through it in a Timeline or a Timestream. The Moment's interface, Bad Wolf Rose, & the TARDIS exist across all of space and time at once. They're basically in a TimePLANE, which is as different as a line is to a plane. You're looking at a MUCH higher dimensional being. What's time locked to everyone in the universe, is capable of being bypassed by means we'll never have access to from within those constraints. That means that even events that are time locked to linear time travel can still be changed.
Now, re-imagine that line on a paper with the gigantic mess of fucked up loops around it that're so complicated that you can't draw any more to it. What those fancy-looking rifts that The Moment creates are the equivalent of lifting something UP off of the paper, and setting it down. There's nothing in the way UP OR DOWN, but the limitations of the timetravel that makes you travel on the paper means that it's not anything you'd be able to do.
This is ESSENTIALLY how you get the Doctor into a timelocked event, but now you have to contend with the fact that this is not ONLY an attempt to make a change to the existing TimeLINE in a way that's small enough that nothing's disrupted, it ALSO crosses into his own TimeSTREAM.
When The Eleventh Doctor is picked up off the paper and set down, back in the latest Present of his TimeStream. He retains all the knowledge of what happened that got him here, and what he changed. The other previous Doctors don't, because they all NEED to keep travelling through that line on the paper to get to that "Present" of his timeline. That's why he "kind of" remembers things as they're happening (this is a lot like what's seen in
Looper with memories autocorrecting themselves when the past is changed, but this effect is localized ONLY to the individual passing into their own timestream in Doctor Who once they're made aware of it, and not ANY change in the past). The other Doctors are basically stuck at being fixed points of Eleven's own past, so they can't retain the information once they leave being together. They all snap back into place.
NOW.
Personal TimeLINES are straight. No zig-zagging from Point to Point. If Eleven looks back into his own TimeLINE - he'll be able to see back to where he and the other 12 Doctors hid Gallifrey Away, because it's only as of the Present moment that that became true. This is the same for if 10 could look back into his own timeline, he doesn't see it, but Gallifrey is just gone, not burned. This is just like Clara looking back in her own timeLINE - she never died in the depths of the TARDIS.
However, from the perspective of both the audience, as well as from the time travellers once they're able to non-paradoxically encounter the information they no longer HAVE timelines. Amy wonders why she remembers having parents and not having parents - this is because she has a timeSTREAM. She both did and didn't have parents. That's why when the world is rewritten without the Doctor, her memory interrupts the timeline during her wedding. She's essentially forcing the Whoniverse rules of time travel to self-correct and allow both of her pasts to exist simultaneously merging at that point. You now have a line with a little line segment going off and away, but they both meet at a single point: Amy's past WITH parents continues through in a line, however, the POINT at her wedding where it self corrects has a non-parallel line segment of her not having parents, but bringing her to the same place. That timeline ends, because the FUTURE that continues is one where she has parents, but her timestream allows her to have experienced both in a non-linear fashion via timetravel.
This is the same with burned Gallifrey. It's there, but it's around the corner in a timeline now, which means it didn't happen ANY MORE. If you look at it in the Doctor's TimeSTREAM, it's still very much there. I always look at the SHOW Doctor Who as the Doctor's Timestream AKA, his "scar tissue of [his] journey through the universe" because we're following him, not drawing a new timeline every time things change. We follow him along the loops, so we're not someone in the future of that universe who can say, "Gallifrey never burned, the Doctor saved it!" both as an audience and the Doctor can say, "Gallifrey DID burn, and that's WHY the Doctor saved it."
Also, this took WAAAAAAYYYYY too much time to write, and I swear that - if requested, I will draw every single linear/non-linear analogy that I made, and upload them all to help this all make sense.
@ ALL your quotes: They're all going TO versions of the Doctor where, if they change who Eleven becomes and the event doesn't play out that way (why Bad Wolf Rose doesn't just tell him), as well as coming FROM individuals within a point in a timeline where that's currently the reality: It's like people telling Amy she had no parents when she still didn't.
