So, yeah, Vel has Seele's interests at heart, but literally no one else's - I mean, Bronya kind of gets folded in because Seele cares about her so much - and so Veliona is
decidedly unreliable when it comes to 'presenting information in an unbiased fashion.'
So my model of how all of this bubble stuff works is different than
@Baughn 's. It's not really grounded in anything particularly physics-y; it makes a
number of unfounded assumptions; and it's definitely a lot more ... self-serving? But it's how I've been making sense of this abstraction, so maybe it'll be useful to other people.
...basically, my thinking is... the Sea of Quanta is full of memories. Fragments of time and thought and emotion. Bits and pieces of reality have fallen into it and fractured, and the remains float in the weird soup of abstract potentiality.
Sometimes, these fragments will assemble into a larger structure - a bubble. But I don't think they assemble the way
reality assembles: I don't think they're glued together by
causation, by time, by effects following causes and the world shaking out of that in a logical progression.
I think they're glued together by
correlation. By a sort of narrative pattern-matching, if you will. I think fragments cohere into bubbles
thematically, along lines of shared emotional feeling or ... similar
enough conceptual feeling.
We know the Sea responds to thought, to attention. I think that's how these bubbles form - that the Sea correlates conceptually related fragments together
in response to the mind's desire to impose narrative.
Practical examples. Take the earlier bubble, where Seele accidentally projected herself into mismatched memories of sisters and family and home; where 'Catalia' was simultaneously older and younger than Seele.
Take this city. It's a mess. It doesn't fit together nicely in space. It goes on forever, and yet Seele is never very far from anything else in it.
So, I think ... I think this city is ... is
made out of city-ness. The people in it are made out of mixed bits and pieces of people who fit in cities. It's a jumble of bits and pieces of memory that are
city-flavored, glued together by its inhabitants, and by Seele, expecting it to be a city. It's unstable - of course it's unstable - because all of these fragments are of differing sizes and shapes and materials, and they don't
fit nicely together. There's friction. There's losses. There's ragged edges and holes and weak seams where the whole thing starts to crumble.
But I
do think that when it inevitably
does pop, that's not - that's not
Okay it's still the end of this little world and everyone in it. But it's not the end of the
fragments.
When you disassemble a Lego house, the house is gone, but the bricks remain. You can build other houses, or rockets, or castles, or pirate ships, out of them.
This bubble is going to go, no matter what Seele does; but its components will reconstitute into other bubbles, in response to other thoughts.
'Traveling' between bubbles, under this paradigm, is less about moving in any real sense, and more about
correlating. It's a matter of telling the Sea "Actually, no, I'm not part of
this story, I'm part of
that one"; and the Sea, obligingly, reorganizing around that assertion - either slotting the traveler into an existing bubble, or possibly assembling a new one to spec.
