Howling:After someone's been absorbed by the Crack...

It's stated numerous times in Series 5 that once an object or person is absorbed into the Time Crack, it never existed at all. Retconned out of history entirely, so to speak (At least this appears to be the dominant theory). But what if you went back in time after someone was absorbed, to a place and time you know that person was, what would you see? Would there just be a patch of empty space where they used to be? After Rory was sucked into the Crack, what would you have seen if you'd gone back to the moment he took the Silurian's gunblast and saved the Doctor - would the bolt just hit air? This, to me, is where the scenario comes apart, as it's just too silly to contemplate. Other people I've asked about this say that after something's absorbed, there'd be a "hole" in time where they used to be, but how the heck does this actually work? I feel it's worth noting that throughout the show, the only time it's noticed that something is gone because of the Crack, is AFTER they've been absorbed, not before. I probably didn't word that very well, but I hope you get the idea. 82.2.136.93 16:30, August 4, 2011 (UTC)

I have come to look upon the plotting and continuity in DOCTOR WHO as very English: if you close your eye and squint it looks about okay, and it actually does work, even though it is neither elegant (in the mathematical sense) nor strictly logical. Talk to an expert in military engineering some time and ask about the evolution of World War Two ordinance in Great Britain and watch 'em turn beet red. Now, how does this apply to the Time Cracks? Explain, if you will, how Amy Pond could be when both her parents never existed? You can't? Neither can I. But it works. My advice is to stop worrying and just enjoy the paradoxes. nd in any cases, the cracks never existed, so I don't know what you're talking about. Boblipton 17:35, August 4, 2011 (UTC)

But if you were to travel back in time AFTER a Crack had absorbed someone, and go to a point where that person was involved, what would you see? Anyway, if Amy's parents never existed, how do people explain her existence? Did she just pop out of nowhere one day? What about all the hospital records that would show her mother being admitted into the hospital on the day she was born, don't they still exist? Some knowledge of her parents must still exist, otherwise how would her aunt know she's her aunt? 82.2.136.93 17:51, August 4, 2011 (UTC)

When you've gone and looked, let me know. Boblipton 18:36, August 4, 2011 (UTC)

Ah, but the Cracks did exist though, otherwise how did they survive the Weeping Angels in The Time of Angels/Flesh & Stone? God, I wonder what it must have been like in the hospital on the day Amy was born....the staff would've seen her just pop out of thin air! Daft. 82.2.136.93 21:28, August 4, 2011 (UTC)


 * You're forgetting that time travelers aren't affected by the cracks the same as normal people. But you can make the same point better by asking what would happen if, as a non-time-traveler, you just waited around until 2020 and went down to the Silurian city, then hid in the chamber and waited for the final scene where Rory got shot.


 * So, what would you see? Well, that depends on your theory of how changing history works. There are a number of possibilities, based on your theory of how changing history works.


 * 1. History keeps itself consistent. So, you'd see a different version of the events of The Hungry Earth and Cold Blood, where only the Doctor and Amy showed up. Some things might be exactly the same, but most of the events would happen pretty differently.


 * 2. There's just a naked paradox there. Even though Rory never entered the chamber, you'd still see everyone acting the same way they did in the episode, as if he were there, the shot would dissipate in thin air, Amy would start crying over a death that didn't actually happen, etc. If you tried to interview the characters, their memories would be completely different from yours, and they'd even have physical evidence to back it up (which might contradict physical evidence you had--e.g., if you'd videotaped the last scene).


 * 3. Somewhere in between: history doesn't make itself fully consistent, but it does hide naked paradoxes. So, everything would be exactly the same up until the point where you could see a difference—that is, Rory doesn't walk into the room, the shot goes wide, Amy cries over something else.


 * 4. History has other ways of protecting itself; it's just not possible for you to get a view of what happened, because the hiding place you chose happens to have its line of sight unexpectedly blocked, or because the shot goes wide and kills you, or the Reapers show up and cleanse the whole thing, or whatever.


 * So, which of these is the "right" answer? Well, they didn't give us any information in the episodes in question, and Moffat hasn't said, so the only evidence you can get is from other stories. The Whoniverse hasn't been entirely consistent on this. The best fit for the classic series seems to be #1 with a bit of #3, at least the EDA novels are definitely #2, while the new series seems to be #3 with a bit of #4.


 * You can explain this by saying that it's the Web of Time that pulls things around to tidy up history, maybe with some help from the Guardians, the Eternals (at least Time herself), etc. In the EDAs, with the Web of Time under direct attack and Gallifrey erased and Faction Paradox running around and so on, that doesn't work at all. Then the Doctor restores everything, but the Last Great Time War starts up, the Eternals flee, both sides are wiped out, and we're left with a Web of Time that's still there, but somewhat damaged, and no longer being maintained. (That last bit comes from RTD, explaining why the Reapers were never seen in the classic series.)


 * Of course most of that explanation goes beyond the bounds of what we see on-screen (and on-page) and is just speculation. The behind-the-scenes explanation is obviously not that someone worked out all of the details of how changing history worked in the pre- and post-LGTW universes; it's that Moffat wants to write different kinds of stories than Cartmel did. So your only choice is to try to come up with a theory that fits the slim facts, or just not worry about it; there's no "true" theory that someone has invented but kept hidden from us. --173.228.85.118 09:15, August 7, 2011 (UTC)
 * Well, I'd like to believe that people like Rory, after they're absorbed by the Crack, aren't TRULY erased from the timeline completely; they just cease to physically exist at that moment, and everything they did prior to that remains unchanged, only other people cannot consciously access their memories of that person due to a side-effect of the Crack. Like a kind of selective amnesia. Honestly, I reckon this sounds far easier to get to grips with than the idea a lot of people seem to have, that after someone's eaten by a Crack, the past consists of those not eaten interacting with an empty space where that person used to be. It's the same with the Daleks in The Stolen Earth/Journey's End - you can't seriously believe, even in the context of the Whoniverse, that after they were absorbed, all those buildings on Earth just blew up by themselves, and people dropped dead in the streets for no reason, or pointed up at the empty sky and screaming in terror! 82.2.136.93 13:12, August 7, 2011 (UTC)
 * These things happen. Poeple think they see things. people have heart attacks, people who never buy lottery tickets win the big prize. It's a funny old world and some days it looks like cause and effect is just an illusion. Boblipton 13:32, August 7, 2011 (UTC)

 * You're attacking a straw man here. The obvious alternative to your story isn't that the same events happened without the Daleks; it's that those events didn't happen at all. The buildings are still there, the people are still alive, and nobody screamed in terror, so there's nothing to explain away. Remember, Moffat's storytelling reason for erasing Journey's End was to make people in the 2011 Whoniverse act like they were never attacked by the Daleks; leaving them in devastated cities with horrifying memories but with the cause of those memories removed wouldn't do that. And neither would your explanation, leaving them in the same situation but with the memories themselves edited to censor the cause. Those people are living on a timeline where Journey's End just never happened. And you can't argue that such a thing is impossible in the Whoniverse, because that's exactly what we saw on-screen in Last of the Time Lords (and other past stories).


 * Also, from a physics point of view, if you assume the consistent histories interpretation of quantum physics, removing the Journey's End Daleks gives you Moffat's altered history for free. (I won't try to explain consistent histories in detail; if you don't know about it, start with the Wikipedia article or Murray Gell-Mann's pop-science books.) Removing the causes but leaving the effects might be plausible. But leaving both the causes and effects while systematically altering the brains of everyone in the precise way needed to edit out their memories of the causes seems to require some kind of intelligent, conscious, super-powerful agent behind the cracks to do that.


 * Finally, watch The Big Bang again: the Doctor tells us that spacetime is shrinking, and we see that the history of the drastically-reduced spacetime has been drastically rearranged to make it as consistent as possible.


 * That's not to say that the consistent-histories explanation is the one the writers always use, but it's pretty clearly one of the explanations in their bag of tricks, and the one Moffat was relying on for his 2010 story arc. --173.228.85.118 00:25, August 8, 2011 (UTC)
