Howling:What exactly did Moffat erase?

There's another thread about Moffat's confirmation that, because of the cracks and the reboot, the highly public invasions of the 21st century never happened.

But exactly which stories got erased?

Most likely the real answer is "whichever ones Moffat needs to get out of the way", and he hasn't sat down and made a list, much less come up with a rationale. But it would still be nice to come up with an in-universe answer. So:

1. Everything after some cutoff. Say, the end of the TV movie; 1 Jan 2000 sounds like an important date (and the 21st century is when everything changes, right?), and it includes all the RTD episodes but none of the classic ones. But this wouldn't take care of The Next Doctor, which the Doctor specifically talked about being erased. Or Terror of the Zygons, which Moffat has called out as the one classic story that can't have been covered up or forgotten. And how does it affect all the future stories, from The Keys of Marinus to Cold Blood (which include every companion death!).

2. A random smattering. A few dozen things were wiped out of earth history, and they just happen to include the handful of public-knowledge 2005-2009 invasions, the Victorian Cyberking, and Nessie in the Thames. Well, isn't that convenient? Pretty hard to swallow, but if Moffat doesn't have a plan, it may turn out to be the only thing consistent with the evidence we get over the years to come.

3. The ones that were "complicated space-time events". We know the cracks like to eat those. And for the most part, the invasions that risked breaking a fixed point in time were also the ones that went public. So this might actually work. And I can almost see RTD coming up with it and suggesting it to Moffat (or to the public).

4. The ones that were incompatible with Amy's worldview. The world was rebooted from Amy's memories, so if Amy believed humanity wasn't in fear of aliens, some things had to vanish from history to make that sensible. The question is, why would Amy believe that?

4a. Subconscious choice. She wanted to live in a world where all the thrilling adventures happened all around the universe, but she had a nice safe home to return to. And the Doctor had already suggested that she could will her parents into existence, and hinted that she could fix Rory's existence problems, so why not try this as well?

4b. Traumatic delusion. She's lying there dying from Auton Rory's shot. The Doctor shows up and says "We'll get you into the Pandorica, take you back to 21st century England, and everything will be OK". That's the last thing she hears before blacking out. Then she's in statis for 2000-odd years, being repaired by the Pandorica. When she wakes up, she believes that 21st century England is safe.

4c. Spacetime shrinkage. There's not just one Amy there--there's also little Amelia, who grew up in a world without stars. Of course that world didn't have aliens blowing up Big Ben every Christmas.

4d. The Silence. In another thread, it's suggested the Silence deliberately blew up the universe so the Doctor would be forced to find some way to reboot it, so they could turn their post-hypnotic suggestion ability into a history-editing ability. While writing themselves into the history of the Earth this way, why not also remove all of the threats that were common knowledge? Even if they weren't worried about the threats themselves, wouldn't they prefer humans who weren't all convinced that the universe was full of hostile aliens trying to enslave them? --99.33.26.0 03:16, May 7, 2011 (UTC)

PS, Doing a search, I found another similar thread from early last year. However, the consensus at the time was that Moffat wasn't actually erasing anything from history (even the original poster agreed), and obviously nobody could have come up with any good answers before seeing The Big Bang anyway. So I think it's better to keep this new thread instead of reopening the old one. But if someone who's more experienced with this wiki than me disagrees, I'll dig it up and reopen it. --99.33.26.0 03:57, May 7, 2011 (UTC)

In Rememberance of the Daleks the Seventh Doctor has already explained why nobody remembers the Loch Ness Monster. He said something along the lines of "humans have a remarkable capacity for self deception," which has always been a theme in both the classic and the new series. More importantly, Ace does not remember ever hearing about the Loch Ness Monster, but Sarah Jane still remembers it in School Reunion. This means that it was not erased, but people simply didn't believe it. Your first thoery doesn't work because we know that before the universe was restored, one event before 2000, The Next Doctor, was erased. Besides, there were classic episodes that took place in the 21st century. If the Cybermen never attack Earth in the 21st century, Zoe won't be a companion. The erasures happened before the Big Bang, so all your theories about Amy rebooting the universe inaccurately are wrong, or people would have remembered the invasions before the finale. The cracks have just always been shown to appear at random points in space-time, so they appeared in the Dalek invasion, Victorian London, Saturnya, the the Byzantium, Starship UK, etc. Some of the events that they erased were events that we had seen or heard of already, to show the audience what the cracks were capable of.Icecreamdif 13:15, May 7, 2011 (UTC)

First, the fact that Sarah Jane remembers Terror of the Zygons doesn't mean that it wasn't erased. That episode happened before the cracks had erased anything. As for the "remarkable capacity for self-deception" explanation, Moffat himsef called this the one story of the classic series that couldn't be explained away that way (or by UNIT coverup, etc.), which is why I brought it up in the first place.

For theory 1, I'm not sure why you felt the need to repeat the exact same arguments against it that I already gave (The Next Doctor, and the classic episodes that take place in the future), but at any rate, I was already convinced that this was the weakest answer.

For theory 4a-c, the fact that the erasures happened before The Big Bang doesn't actually prove anything. First, we don't know whether anyone remembered the invasions beforehand; we only saw that Amy didn't. From the time we saw the first crack to the finale, not once did anyone mention any of those events. And, oddly, the Doctor never thought to ask Rory, River, Nasreen, etc. about them (which is the first thing I'd do if I were trying to figure out why Amy didn't remember them). So, we don't actually know either way.

Finally, you argue that theory 2 must be the answer because "the cracks have just always been shown to appear at random points in space-time"--but they _haven't_ been at random points. At least not the ones we've seen or heard about. Those appeared at points very near to where Amy and the Doctor were (including the ones on Saturnyne--one of them connected to Venice during Amy's arrival like a wormhole, and the others were near that one). Of course it's possible that there were millions of others that we didn't see, but it's just as possible that there aren't; we don't know either way.
