Think of shapes drawn on paper (these are geometric objects). Now imagine you want to keep track not just of one shape, but of all possible shapes that follow certain rules — like every possible circle, every possible triangle, or every possible twisty curve. A "moduli space" is like a big catalog or playground that organizes all those shapes so you can look them up.

An "Igusa stack" is a special kind of catalog (a stack is a more flexible catalog than a plain list) for certain geometric objects that come with extra structure used in number theory. Two key ideas:

Objects: The shapes being cataloged are things like "abelian varieties" (think of these as higher-dimensional, very symmetric shapes that behave like circles but in complicated ways) together with extra markings, like special points or a way to measure them.
Stack vs. space: Sometimes many different objects look the same from far away but have small internal symmetries (like two identical toys with different stickers). A plain catalog would lose that sticker information; a stack remembers it. So an Igusa stack keeps track of objects and their symmetries carefully.
Why "Igusa": Named after mathematician Jun-Ichi Igusa, because these stacks record structures important in studying how these geometric objects behave when you do arithmetic (counting, working modulo primes, etc.). They show up when studying the shapes in families and how they behave over places like the whole number system or modulo a prime.

>how to deal with the unknown unknowns?
You continue data collection and theory refinement to look for unexpected anomalies or behavior. Really just that. You prepare for and plan for what you expect, have a safety margin that is calculated and observe as many data points as possible to detect something unknown.
>>
>>16962071

>>
experiements pretend the working space is a closed system, an unknown unknown in context is something that is not foreseen as far as explanations go
generally the literature can presume these effects as negligible, the idea isn't that unknown unknown is predictable but whether or not we cleared the field for cause-effect purity

like that oceangate thing, as a boss would you look at carbon fiber again even if in your limited knowledge of material engineering, it''s worked everytime, unknown unknows are always counter intuitive

There are infinite natural numbers. You can take each of those natural numbers and multiply them by 2 and get another infinity of natural numbers. You could do the same thing with 3, 4, 5, etcetera. That must mean that there are infinitely infinite infinities, ad infinitum, ad infinitum, ad infinitum, etc, etc, etc,…(…)…

All the results of your multiplication are naturally already included within our baseline infinity. This infinity plus one rubbish just stems from an inability to conceptualise the basic nature of an infinite set

All experiences fall into a few fundamental types. Everything you've ever lived fits into these:
- Perceptual Experiences (the "world")
- Mental Experiences (the "mind stream")
- Emotional Experiences (the "felt tone")
- Bodily Experiences (the "inner body")
- Volitional Experiences (the "doer sense")
- Awareness Itself (often missed)

[math]{\delta}S=0[/math]

It's existed since the 1800s, and it's fucking beautiful. And some may say, "What's the specific action needed for GUT, though?" My answer is who gives a fuck? You asked for the equation that explains everything, here it is. The action is minimized and that's why all the shit that has ever happened and will ever happen, happens. The end. I'd like one Nobel Prize please.

Consciousness is a result of physical phenomena, some atomic/subatomic particles in the brain produce it. It is a feature of the universe, of physics. We are inside one universe, one physics, therefore there is a single receiver of consciousness. Single actor that experiences it. But the experiences are separated because there is no memory shared between two people. We have separate brain and memory, that's why there is an illusion of many humans, people. But it is an illusion. When you have stomach ache, but then some other person has it too, the result is the same. You think your one (stomach ache) is more important or even that only you have consciousness, but in the universe there is only one consciousness receiver. We are just atoms formed in specific combinations and the brain allows to experience consciousness.

This theory and phenomena extends to animals, including the ones that are eaten alive in the jungle or raised for meat in cages. It even extends to aliens on another planets, as long as they evolved similar mechanism. They could evolve different consciousness though, or no consciousness at all.

It is not enough to avoid your own suffering, we have to avoid suffering of all living, conscious beings. All animals (including humans).

If you make some harm to animal or human, it is the same as if you did that to yourself, you will feel this pain, just in another "dimension", another timeframe.
In some way, there is a single "person" in the universe, the single receiver of consciousness, he is alone in the universe. Multiple, separate people and animals are just an illusion, delusion. They are illusion as a side effect of people's memory being separated into each brain and inaccessible by others.

This is just hyper object consciousness and John Birch’s theory together. It’s fairly solid in meta. Some people won’t like the idea that animals have awareness or that people may not have a traditional soul. I think you could do souls in these systems, but it might mean all animals also have souls. Generally it means that all awareness is the same root awareness and that any harm done to one is done to all. This isn’t really a novel concept, it’s a very frequent thing that comes up as people begin to reflect on consciousness. I’d be more interested in what the biologists have to say.

I would claim that idea is very similar to some ideas in buddhism and specifically to the idea of buddha-mind. The self and the mind are fictions under which there might be a network or plato’s forms or a substrate. Then that network or form or substance or particle become this monist idea that hegel talks about and also this idea has physical manifestations to the probability function and the relativity of the probability function, as a physical theory or a theory about physics, and also as a theory about information, which would result in observable quantum artifacts, such as the double slit experiment and where the idea of taking a measurement has theoretical and practical concerns already attached
