Howling:Is the Bubble Universe really e-space?

Could the Bubble Universe featured in The Doctors Wife actually be e-space? From the events of Logopolis we know that one of CVE's to e-space was left permanently open. Could this be the rift the doctor travels through in ''The Doctors Wife? ''The Doctor also describes the bubble universe as being like a plughole universe though which stuff falls through, which kinda fits the discribtion of e-space with the entropy being funneled into it.

E-space may be smaller than N-space, but it is not as small as the bubble universe seemed to be. Also, as the Doctor has been to E-space he would likely have recognized it and called it by name. Even if Amy and Rory didn't know what he was talking about, he would have said something like "this is E-space. It's a different universe, with negative coordinates. Think of it like a bubble etc." Besides, when the Doctor fell through the CVE the first time, he didn't have to delete rooms to gain enough power to reach E-space. He never deleted rooms until 2 episodes after he returned to N-space.Icecreamdif 02:23, May 25, 2011 (UTC)

To add to what Icecreamdif said, the Doctor suggested that there are potentially lots of bubble universes, but there's just one E-space.* Also, whenever the technobabble has been a plot point that they wanted us to look back and say, "Ooh, how cleverly they set that up!", it's been simple and obvious. For example, in The Big Bang, all you need to know to understand that is the basic idea that there are cracks in time because spacetime is being torn apart; you don't need to compare and contrast the cracks to the Cardiff rift. Likewise, to understand the Master's plan in Logopolis, all you need to know about CVEs, BTCs, and heat death is the handful of words the Doctor told us; you don't need to work out how the BTCs would affect the lambda-CDM model.

* OK, I'm cheating a bit there; that's an inference from common sense, and common sense probably doesn't apply. In fact, if you really want to make sense of E-space: Negative coordinates are ridiculous in the Doctor's explanation (unless you think the Southern hemisphere is discontinuous from the Northern on our planet?), but they could be a Doctor-ish way of getting across the idea of T-duality to unsophisticated people like Adric (or possibly even the Doctor forgetting his Academy physics and remembering the metaphor he learned as a Time Tot). The novels establish that the 11-dimensional M-theory is a reasonably accurate description of the Whoniverse, which means you can choose lots of arbitrary D3-branes to be T-dual to the D3-brane we live on, and hence lots of E-spaces. But, while that's the kind of thing they might spring on you in a blistering string of irrelevant technobabble, it's exactly the kind of thing they'll never expect you to work out on your own. The Doctor said negative coordinates, and you only get one unique negative universe for one positive universe, so we're meant to expect there's only one E-space unless told otherwise. --99.20.128.35 07:47, May 25, 2011 (UTC)
