At first I thought  you ment The Shedd in SmF.  If instead you mean the portal Harry used to get to Edinburg from Chicago (I think it was near a slaughterhouse) that was monitored by the contracted out P.I. and Mouse, yah, that certainly seems to contradict things.  Plus Harry's experiences following his Mother's advice.

I think those apparent contradictions could be remedied by considering the intent though. 

The underlying point I was trying to make though, is that it isn't necessarily a 1:1 topographical correlation between the mortal world and the NN. 

I had a prof in my junior year who was lecturing on mathematical fields do a pretty good job of explaining how you could topographically map an infinite plane onto a sphere.  That took some mind bending.

Even in this reality, I don't buy that somehow the NN is only an infinitesimal fraction of our actual universe.  I mean, that's not even one AU.  That's not even the area of the Sun in 3D space.  Much less the areas that humanity has expanded to via satellite and probe.

My understanding of (admittedly, a half remembered quote) is that Earth to the Moon is about as far as you can travel, but not as far as there is, in the same way that about 40 Km is the highest we can fly.  There's PLENTY more out there, we just can't get to it right now.

I think that at the very least, there has to be some sort of topological 1-1 mapping.  After all, I think we have evidence that you can open a portal to the RW anywhere in the NN.

So? All that proves is the NN spirit realm contains thoughtforms from other planets. Doesn't make it reality and Sorry ducky, your Numeromancy doesn't impress without sound logical reasoning taken from cannon. The NN isn't reality and while it can contain alternate worlds it doesn't make them 'real' in the technical sense. All I infer from this is that since the NN only physically encompasses earth and moon, it used to be bigger. The alien worlds in it exist in spirit only because the outside has already retaken them.

Dudesan: Do The Dresden Files and The Codex Alera share the same metacosmology? Were the many migrations (such as the ancestors of the Alerans, the Marat, and the Canim) through the Nevernever? Should we worry about a Vord invasion of Earth? Bob mentioned that many worlds thought to be fictional do exist in some sense- I think his example is that "Spider-man is real... somewhere out there. What, you think this is the only world?"
Jim: 2) What kind of insane person would design a universe like that? Next you're going to come up with some kind of theory about how a single extended family bloodline runs through all of these obviously unrelated story universes, and how all of my central heroes actually belong to one family.
Psssh. No one's going to buy that.
Dudesan: What we've seen of the cosmology of The Dresden Files seems very Earth-centric. Is that because everything really does revolve around the Earth[1] , or because we're seeing only a tiny slice of a much bigger picture? Are there other planets in real-space inhabited by extraterrestrial sentient beings? If so, do they have their own analogues of wizards, fairies, gods, etc? Are supernatural things influenced by their belief as it is by those of humans? If so, to what extent do these "spheres of influence" overlap?
Jim: 3) Everything revolves around /this/ earth, in the Dresden stories. But not necessarily around all (or even a majority of) the other earths that exist in the continuum of possibility created by free will. Other, parallel realities have other worlds playing a more central role, and some of them have earth in a nice quiet backwater, peaceful, relatively conflict free, and boring.

things are a bit err Squishy on this but maybe what happened is that Harry opened a Picogram sized Black Hole for a Picosecond so that the effect was SPLAT! (and what we "saw" was the result of Harry bending Space/Time how he wanted).


Of course Now since Harry is The Winter Knight and can tap The Winter WellSpring he might decide that an entire BLOCK needs to be flatter.

I could also see Harry making a Staff and Cane combo for when Father Forthill needs to Rebuke Mountains.

Here is a thread on the subject.

Does this mean that we can never use arguments based on calculations again?

In case you noticed, it isn't.
