Hopefully this doesn't make me seem like a crank, but it seems to me that the path forward on superdeterminism is to use uncomputability.
1: Untriangulable smooth manifolds exist.
2: The manifolds can be smoothed via Ricci flow in a manner similar to how Perelman solved the Poincare conjecture.
3: This smoothing, applied to an untriangulable manifold, is irreversible, deterministic, and yet somehow must not converge to any triangulable manifold.
- ajkjk 7y agoI'm having trouble seeing what any of that has to do with determinism.
- sdenton4 7y agoCranks to the left of me, jokers to the right, here I am, super determined with you... Even the comments on the blog post seem exceedingly cranky. I can imagine it's very hard to work in such an area, with such a noisy peanut gallery.
- vanderZwan 7y agoIf you click through to the lecture she links by Tim Palmer[0]it becomes clear that he's got to deal with this on an even worse level, because he works on both this topic and on the physics of climate change. The comments there are just painful to read. https://www.youtube.com/watch?v=w-IHJbzRVVU https://www.youtube.com/watch?v=w-IHJbzRVVU
- AlEinstein 7y agoBecause Perelman. I mean he wrote Perelman’s name so he must be onto something.
- ouid 7y agoThe evolution of a manifold under Ricci flow is deterministic as mentioned, and it is also irreversible, ie many manifolds are smoothed to the same manifold. It's also a diffeomorphism, meaning that it preserves all of the topological information of the manifold that it acts on. Furthermore it can act on manifolds which have no normal form, in at least some sense. Because smooth manifolds with no triangulation do indeed exist. The manifold cannot, in whole, as a result of this, get "simpler" or even maintain the same amount of simplicity, it must somehow get more complex, which would require information to be generated. The primary problem with deterministic models, at least as I understand it, is that there's no obvious way for deterministic processes to get more complex.
- comex 7y agoAren't diffeomorphisms invertible by definition?
