Not Knot

Not Knot was created at the Geometry Center / Geometry Supercomputer Project in 1991, directed by Charlie Gunn and Delle Maxwell.

Fun fact: This is a canonical part of the original lovecraft lore on how many eldritch beings work/perceive/traverse reality. The city the great old ones live in under the sea for instance, is made of 4th dimensionally hyperbolic geometry. There's even creatures that specifically use abstract spacial geometry to teleport across vast multidimensional distances, fir nothing more than primitive hunting techniques.

[@ryanh5987]

I've thought of reality in this way for quite a while. The notion of extra dimensions seems to legitimize, to an extent, spirituality and religion in general, as well as lots of what's known colloquially as 'superstition'

[@suruxstrawde8322]

@@ryanh5987 🤔🤔 hmm, idk if those connect (exactly), given almost none of them can really be seen outside here say and stories, especially given ppl who say they can “sense” presences almost always have sensory disorders. But it does lead to science just being magic we can explain, suggesting superstition is seeing real things occasionally, but misinterpreting the how and why. There’s a big difference between assuming something is true, and misinterpreting a preexisting phenomenon.

[@gringusgaming]

​@@suruxstrawde8322I think what he means moreso is that it provides more legitimacy to certain ideas like the "soul", or in other words our "ego" or consciousness existing as more than a concept, but outside of our available perception due to the lack of a need to perceive it evolutionarily. I know that as humans, we generate electromagnetic fields, and many liken that to an "aura", so this could be similar. That said, we have basically no way to know lmao, this is pure speculation

[@sethrenville798]

Isn't really a hallucinatory calm though? In the animation of hyperbolic geometry as it changes, within a perspective, isn't that exactly what we experience from our specific perspectives, for example within a moving car, objects farther away appear to move more slowly than those close to us, and as we get closer to objects they appear to increase and size?..

Not a knot: nothingness entwined, Knotting a knot? Impossibility defined. As I align these dotted words I see, On temporal canvas, mine and free. A million quanta, shimmering bright, Silent motion, shaping cosmic flight. Do I truly grasp knotting's might? A wonder to ponder, where no chords resound. Naught but the soul, in silence found.

[@BodyMusicification]

Random thought: if the complement of your self is everything you are not, then every time you move your body, your complement also shifts, meaning you are affecting the shape of everything you are not as well-making us kind of strangely connected to the entirety of the rest of the universe. However, like unraveling a knot, unraveling your self leads to a mathematical equivalent no matter what pose it is currently taking. So, when moving, have we really changed anything at all? Or just shifted around some molecules while everything is fundamentally unchanged, forever actually. Does time even exist if you consider the unchanging nature of everything in this way?

At different levels that is ultimately true I suppose. The whole oneness thing, while trying to maintain a concept of individual or "separateness." I'm not trying to discount your words. I'll probably think about this sometimes. It's actually a good way to conceptualize "oneness"

[@zonesquestiloveunderworld]

No, the idea of a "complement" is just for the mathematician's convenience so they can actually explain things. It's not something that actually exists. That's like thinking everything in the universe is on a grid because you've seen space represented with grids in documentaries like this. It's just there for ease of understanding. You don't think atoms actually look like those models with different-coloured spheres do you?
