Howling:If the doctor never existed...

when the doctor was errased in the big bang (tbb), how could there still be a universe for amy to live in to remember the doctor back into existance, since if he didn't timelock the last great time war (lgtw) then rassilon would have destroyed the universe, amoung other things the doctor will never have saved the universe from? Imamadmad talk to me 06:43, October 19, 2011 (UTC)

Same reason Amy can still exist even though her parents never existed-when the cracks erase somebody, they don't erase that person's impact on the universe. If it did, then the Time Lords destroying the universe wouldn't be a huge problem. Look at Turn Left and see what the effect is on one planet, when the Doctor's only been dead for two seasons. Now, imagine if he was never born. His impact throughout history remained intact, even though he never existed. Just how that works is anybody's guess.Icecreamdif talk to me 06:52, October 19, 2011 (UTC)

It's arguable that, if the cracks had erased the Doctor's impact on the universe, they'd have erased themselves. Without the Doctor, no Doctor's TARDIS to explode, therefore no cracks caused by the explosion -- and, also, the universe wouldn't have been destroyed by the explosion. --89.240.241.19 14:08, October 19, 2011 (UTC)

What Doctor's impact? There have always been cracks in space. Boblipton talk to me 15:04, October 19, 2011 (UTC)

No there haven't. They only showed up in season 5. They were caused by the TARDIS explosion. The cracks may not have existed without the Doctor's impact, but the universe would have been destroyed by the reality bomb, or Rassilon, or whatever was supposed to be happening in Logopolis, and the Earth would have been destroyed about a thousand times. Still, we know that the cracks do not erase people's impact on the universe, because Amy still exists without her parents, because the Byzantium still crashed without the Angels, and because the clerics weren't replaced with other clerics when they went through the cracks.Icecreamdif talk to me 20:34, October 19, 2011 (UTC)

Icecreamdif: All correct. Without the Doctor's impact, the universe would have been destroyed by something else, but not by the cracks. The (limited) point I was making above was that the cracks couldn't erase the Doctor's impact without causing a paradox, because they were part of his impact. If they'd erased the impact of those whose existence they erased, they couldn't have erased the Doctor at all. --2.101.58.9 (formerly 89.240.241.19) 21:22, October 19, 2011 (UTC)

And my point is what Doctor? He never existed. Just because we haven't figured out how all these things happened doesn't mean they don't have a logical explanation. Given any set of facts you can come up with a logical system to explain them. Boblipton talk to me 01:46, October 20, 2011 (UTC)

So then where did Amy come from? What caused the Byzantium to crash? Why was Amy left alone with no clerics guarding her? These things don't have logical explanations, because there cause was ripped out of existance. The effect of these causes, however, was not removed. After the explosion, the universe seems to have given up on logic altogether, with all the countless paradoxes involved in the ever shrinking history. If Earth is the only thing in the universe, then where did it come from? Why build a museum if there's nothing to put in it. If little Amelia never existed, then where did Amy come from. We know how these things happenned-they happenned due to the effects of people and events that never existed. This is very paradoxical, and it leaves open a lot of questions, such as what would happen if, pre Big Bang 2, the Doctor travelled to the date of Amy's birth? Would she just magically appear out of nowhere? When the cracks are involved, there is no logic behind anything.Icecreamdif talk to me 06:15, October 20, 2011 (UTC)

There would be a universe in which some children exist without ever having had parents. There wouldn't be many of them, likely, but they would exist. People would debate whether spontaneously generated children was proof that God exists, laws would be passed to deal with the legal issues of citizenship and guardianship and Cyril Burt would produce enormous numbers of studies about their development which fifty years later would turn out to be bogus. Boblipton talk to me 12:38, October 20, 2011 (UTC)

Not really. History doesn't change when somebody is erased, except for the obvious effect of removing that person, so there wouldn't be a new history where people had always wondered where it came from. Just look at Amy. It didn't even occur to her that it was weird that she didn't have parents until the Doctor pointed it out. We haven't seen much of her aunt Sharon, but it doesn't seem like she was concerned about the fact that she had a niece but didn't have any siblings. We know that Amy was sent to several psychiatrists, and none of them seem to have noticed that Amy somehow didn't have any parents. Apparently one of the effects of the cracks is that people don't notice these obvious indescrepencies. Icecreamdif talk to me 19:08, October 20, 2011 (UTC)

It goes beyond not noticing the discrepancies. To judge from Amy's conversation with the last surviving cleric in the forest on the Byzantium, they resist having the oddities pointed out to them. Aunt Sharon's reaction (in the dying universe) to Amelia's painting of stars wasn't to shrug it off as a child's imagination; she was seriously worried by it and acted as if a belief in stars were somehow harmful -- she was, in fact, actively hostile to the idea. --89.241.66.33 23:46, October 20, 2011 (UTC)

Well Aunt Sharon's reaction may not be a reaction to the cracks. She sent Amelia to a few therapists because of her "imaginary friend", but the Doctor was never sucked into a crack. Aunt Sharon is worried in general about Amelia's overactive imagination, and adding to that the fact that star believers were considered to be angry cultists, you can understand why Aunt Sharon was worrried even without intervention from the cracks. You are right about Amy's conversation with the clerics though. They do resist having information poined out to them.Icecreamdif talk to me 01:25, October 21, 2011 (UTC)

"star believers were considered to be angry cultists": Exactly so. Why? The point is that it wasn't only Aunt Sharon, it was general. Believers in (say) the Flower Faries are regarded with pity/derision but not with hostility, so why were believers in stars regarded with hostility? My guess (and it is only a guess) is that talk of stars made most people slightly uncomfortable -- they didn't want to go there, just as the clerics didn't want to go where Amy's information would have led them. --89.241.77.97 21:24, October 21, 2011 (UTC)

Whenever I think about things like how Amy can still exist without parents, how the Byzantium can still crash, how the Doctor still avoided being shot by the Silurian at the end of THE/CB, the simplest explanation to me is that everything absorbed by the Cracks always exists UP UNTIL THE MOMENT A CRACK APPEARS AND EATS IT; the sequence of events prior to that moment is unchanged, as is evident from stuff like Amy's continued existence, etc. A lot of people seem to think that once eaten by the Crack, things LITERALLY never existed at any point in the timeline, but that would be like trying to build a house from the roof downwards - it just doesn't work, and doesn't make any sense. If that is the case, then you have to jump through all kinds of hoops to make the current scenario consistent with how it was before the Cracks showed up, which IMO makes it even more convoluted. Of course, there are still things like the Doctor specifically saying that every star will supernova at every moment in history if the TARDIS blows up in TPO, but maybe he just meant every moment in history in the future of where and when he and the Alliance currently were in that episode....maybe, I don't know. Why do people forget the things absorbed by the Crack afterwards? I don't know; perhaps it's linked somehow to the Silent's natural ability to cloud people's memories of them when they're not directly observing them, or perhaps it's just how the Cracks work. I realise my ideas aren't particularly popular, and no doubt a number of people will probably poo-poo them. But I'm a naturally logical person, and so like things to have logical explanations. Besides, it's inconsistent with how paradoxes work elsewhere in the mythos: When Rose Tyler saves her father's life in FD and distorts the timestream, the Reapers manifest to sterilise the breakdown. And when River Song doesn't kill the Doctor when she's supposed to in TWORS, all of history breaks down into a chaotic jumble. Thanks for reading. 82.2.136.93 15:08, November 5, 2011 (UTC) That's because it was stated, repeatedly, that things that were swallowed by the cracks never existed. We even see directly this is the case in The Big Bang, remember the cracks are pre/after-shock to the TARDIS exploding, and at the moment it does explode it erases most of the universe from ever existing like the cracks did it was the source of the cracks. Also I've mentioned before comparing the workings of the cracks to other paradoxes in the series is mostly useless because you have to look at circumstances: When Rose summoned the Reapers that was because of a simple paradox and the universe being slightly damaged, like cutting a finger. When the TARDIS exploded it was more like being hit by a truck, the universe was being blown away, all of it, regardless of position on the timeline because everything ever was ceasing to have ever existed in the first place. This is how we know the cracks do what it is said they do because they are part of that explosion. The Light6 talk to me 02:35, November 6, 2011 (UTC)
 * "A lot of people seem to think that once eaten by the Crack, things LITERALLY never existed at any point in the timeline"


 * But then you have to jump through hoops to explain how, if the Weeping Angels never existed, the Byzantium still crashed. How the Doctor survived getting shot at if Rory never existed. If Amy's parents never existed, where did Amy come from? If the Cyberarmy in AOG/DD never existed (as can be inferred from recent episodes), how did Torchwood 1 still fall? If the Dalek army in TSE/JE never existed, how did Harriet Jones die, and how did Donna end up being half-Time Lord? Etc, etc. 82.2.136.93 10:58, November 6, 2011 (UTC)
 * Yes you do, but those are the same loops you have to jump through to explain how anything in The Big Bang happened. Remember after the TARDIS exploded nothing had ever happened ever, except for the rapidly erasing history of Earth. If no stars ever existed, how did all the Hydrogen become the heavier atoms needed to form earth and the life that in habits it? Many alien races over the history of the show have been shown to have important parts in the history of earth and humanity, how was humanity still close to where it was in The Big Bang if none of those races ever existed? Here's the thing, as appealing as it is try to hop around the issue to avoid the hoops, the fact is that they are there and the only way to explain it is to hop through those hoops. The Light6 talk to me 11:45, November 6, 2011 (UTC)

Well, I think what 82 is trying to argue is that the stars and hydrogen and everything else still existed before 101 CE, but it was after that point that every moment in history ceased to exist. I suppose that could explain where the legends of stars came from, but that theory also goes against every line of dialogue that has ever been utterred about the cracks. For one thing, that would mean that the Doctor co;uld use his vortex manipulator to travel to the year 100, and everything would be fine. THe implication of the episode was clearly that there was no universe anywhere or anywhen. The Doctor always says that people will have never existed, so when people are sucked up by the cracks they never existed. Simple as that.Icecreamdif talk to me 19:17, November 6, 2011 (UTC)

Well in that case, when it comes to stuff like Amy's continued existence without ever having had any parents, the Byzantium still crashing, the existence of CyberLisa in TW Cyberwoman, and what killed Harriet Jones, etc, etc....there is no rational explanation. They just happen, even though they make absolutely no sense as the things which cause them never exist. It just bugs me. 82.2.136.93 16:58, November 7, 2011 (UTC)
