Theory:Doctor Who television discontinuity and plot holes/Doomsday


 * The Doctor expressly states that there is nothing in the void in "Army of Ghosts" and earlier in "Rise of the Cybermen"... so where has the "void stuff" come from?
 * The Doctor was wrong, was lying, was simplifying a complex topic, or was merely discounting the value of seemingly unimportant subatomic particle radiation. As Rose mentions in this episode, travel in the Time Vortex soaks you in harmless radiation; this information primes us for the realization that travel throughout the void does a similar thing.


 * When Rose was about to be sucked into the void when Pete rescued her. Wouldn't he have been sucked in?
 * The Daleks and the Cybermen had spent years crossing the void and would be completely coated in the void radiation. Pete would not have been exposed to as much of the Void stuff as he had only been transported across the void about 3 times.
 * It may take time before the void stuff begins to get sucked into the void. Before flying into the void at high speed, the Cybermen hovered for a second, seemingly only being pulled in very slowly to begin with.


 * Even so, Rose had only traveled about as many times as pete. Why was she sucked forcefully?


 * How would Pete have known when and where to teleport to grab Rose or that she even needed saving?
 * He didn't need to know where to teleport as the teleporter goes to the same spot in the other world, and he caught her on instinct/reflex.
 * Also, Pete wasn't showing up to catch Rose, he likely coming back to please Jackie.


 * How does the Doctor know "hope" is going to come with Jake's return?
 * In a deleted scene, the Doctor talked to a Cyber Leader about emotions. "Hope" is an emotion, and, in this case, is the emotion felt when wanting "something", in this case Jake, to intervene and save him.
 * The Doctor has additional senses and could have possibly have felt an impending distortion. At that point, any change would give him hope.


 * How did Rose know that she had used the Time Vortex at the Heart of the TARDIS to destroy the Dalek Emperor? She didn't remember anything at the end of The Parting of the Ways.
 * There was ample opportunity over the course of the intervening season for the Doctor to explain anything which Rose may have forgotten, which is likely as she may have questioned why he had to change further.


 * The Doctor tells Mickey that if the Cult of Skaro tried to open the Genesis Ark by force they would have destroyed the sun. How could he possibly know this with no knowledge of the Genesis Ark or the technology available to the Daleks?
 * He may know how it opens, simply not what is inside it.
 * He also may be suggesting one of their possible courses to make Micky feel better and shut him up.


 * When Rose and The Doctor are sucking the Daleks and Cybermen into the Void, Rose's switch is pulled down. She pulls the switch back up and the switch locks. Why didn't the switch lock the first time?
 * The Doctor could have been in a rush to suck in the Daleks and the Cybermen into the void and could have forgotten to lock Rose's switch.
 * This doesn't make sense since if you look closely they should automatically lock as the lever handles have to be pressed together before they can be moved.
 * Sometimes even rachet lock mechanisms will slip if not be properly seated.


 * When the void first opens, pieces of paper are seen floating around. How would they be attracted to the Void if the paper obviously hasn't traveled through the Void.
 * The Void could be creating enough energy to blow some paper around.
 * Also, the Daleks and Cybermen being pulled into the void would displace air as they flew toward the breach. This air movement could cause the paper to fly around.
 * Ambient void stuff radiation from prior openings returning to the vortex could move the air in a manner similar to how water moves air in the hydraulic ventilation used by firefighters.


 * Shouldn't the TARDIS and the Daleks' Void ship have sucked into the Void as well? The TARDIS should have had Void stuff from when it travelled to Pete's World.
 * The Doctor probably put it in 'park'. That, and the TARDIS was several hundred floors down inside Torchwood Tower itself.
 * But the void pulled in Cybermen from across the globe, considerably more distance than from the base of Torchwood Tower.
 * The TARDIS was mostly dead when it landed in Pete's World. Perhaps the void stuff can't “stick” to inert objects.
 * The Void Ship was designed to travel across the void and doesn't register mass, temperature, etc. It is “invisible” to the Void and thus unaffected by it.
 * Also, we don't know how heavy the TARDIS is. Maybe it can't be lifted, except by its own propulsion systems.
 * We have seen its exterior lifted with fairly little effort several times. To name one example, when Caecilius was sold it in The Fires of Pompeii.
 * The TARDIS has defenses, even some that can be set to automatic, such as the forcefield from the Tribophysical waveform macro-kinetic extrapolator. Moreover, we're shortly to establish that at this point in the Doctor's TARDIS lifespan, she can manipulate at least some of her own settings TV:Utopia (TV story). She's also recently been seen to resist the gravitational pull of a black hole. TV:The Satan Pit (TV story)


 * Why were all the Cybermen sucked into the Void? Many of them had been converted on earth, and so had never been through the Void - such as Yvonne and Lisa in Torchwood. Lisa wasn't pulled through, yet all of the others appear to have.
 * It is possible that the materials used to make the Cybermen were brought through the void with the Cybermen and so would have gotten void radiation on it. As Lisa was one of the last converted, the Cybermen may have run out of materials from Pete's World and used materials from this world, meaning that she would not have been pulled into the void.


 * When Dalek Sec and the Genesis Ark rise out of the battle with the Cybermen, why didn't the rest of the Cult of Skaro join them?
 * They were no longer needed to aid the Genesis arc. All that was then left to do was to destroy the world, starting with the Cybermen.


 * How can Pete teleport Rose safely away when Mickey clearly said the teleport only works on 1 person, and Pete was shown with only one teleporter in hand?
 * Pete could have had a second one in his pocket.
 * The teleport may only work on one person, but the universe travelling may not support only one.
 * Pete had one on a chain around his neck and a second one in his hand.
 * However when he returns to his world we clearly see that he is only in possession of one teleporter, also when he grabs Rose he only activates one teleport so he shouldn't have teleported back.
 * Pete could have had a different model teleport.
 * Pete and Rose could have had similar enough DNA that the teleport would treat them as the same person.


 * When dalek sec says "emergency temporal shift!" he should getting sucked into the void like the other daleks, not levitating still in the air.
 * Before the Cybermen got sucked they hovered in the air for a moment, so Dalek Sec probably went up a bit which alarmed him (it?) and thought of using the emergency temporal shift.


 * When the Cybermen on the streets firing at the Daleks are sucked in, only two out of a group of 32 are shown to be dead. Although they had Daleks shooting at them relentlessly for 5 minutes.
 * The Cult of Skaro are said to have far superior capabilities to normal Daleks. Perhaps the weapons and shielding of the Genesis Ark Daleks is inferior to the Cult, meaning that the Cybermen could hold their own against them.


 * Sarah Jane Smith has time travelled before meaning she has the "void stuff" she should have got sucked into the void as well.
 * Time travelling doesn't equal void travel watch the fore mentioned episodess and check your facts
 * Also, travel in the void before the demise of the Time Lords may have hazards that weren't present before. They may have had devices to atomically cleanse anyone's void stuff on your reentry to normal space that no longer work with Gallifrey gone.


 * How did the daleks know the doctor was a threat? They haven't seen this incarnation.
 * It probably struck them as odd to see someone wandering about when there was a Cyberman invasion, and then they scanned for the reaction (Rose's heartbeat) and when she said it was the Doctor, it obviously struck a chord for them. I am the last of the Time Legos. ☎  18:20, November 16, 2012 (UTC)
 * Or there is something in the void with corrupted information on later incarnations of the Doctor and they had access to it.


 * It seems awfully convenient that when the Void sucks Daleks and Cybermen from all over the world, that their travel path is redirected through the same window on the building. This would seem to imply that the "void-sucking force" is unidirectional when near the Void but omni-directional further away.


 * When the Cybermen give the order to converge on London, how could they realistically expect the Cybermen on the other side of the world to get there in time by just marching?
