Brain Taxonomy

Toposophic classification, limits of computation, and the vast array of technologies, physical principles, memetic differentiation, and information theory make theology a bizarrely difficult subject to exchange information about, even when the two beings conversing have relevant conceptual equipment based upon roughly similar protocols. In such discourse, short-hand is necessary to even agree upon common reference memes. Throughout the history of memetics and theology, several tropes have descended towards common baseline understanding, particularly when describing the physical basis of theology. Several examples are given below, with disambiguation references. Each trope can be likewise fractally expanded to suitable complexity for a given information protocol.

M-Brain: An archailect based upon a computational substrate comparable in mass and size to a small moon or rocky core of a planet, typically in the 1E23 kilogram range. The computronium basis usually corresponds to a highly ordered metastable material structure, with diamondoid or ferroid being the most common. Such complexity is often considered to be the bare minimum housing for an archailect at the full S3 rating.

J-Brain: An archailect based upon a computational substrate comparable in mass and size to a gas giant planet, typically in the 1E27 kilogram range. The computronium basis usually corresponds to a colloidal structure of plasma, monopolium/magmatter, and/or diamondoid/ferroid. Such complexity is often considered to be the bare minimum housing for an archailect at the full S4 rating.

N-Brain: Also called a neuron star, an archailect based upon a computational substrate comparable in mass, size, and density to a neutron star, no more than 4E30 kilograms or 2 solar masses. The computronium basis usually corresponds to collapsed matter such as neutronium, although more exotic quarkonium components may be involved. Such complexity is often considered to be the bare minimum housing for an archailect at the full S5 rating.

S-Brain, also known as a 'Godstar': An archailect based upon a computational substrate comparable in mass and size to the most massive stars, at minimum 10 solar masses. The computronium basis usually corresponds to a colloidal structure of plasma, monopolium/magmatter, and/or diamondoid/ferroid, but unlike a J-Brain, the majority of computronium is plasma-based. It is not know to what toposophic level an S-Brain can reach, but simple information theory would suggest S5+, possibly with spikes to S6 or beyond. S-Brains can exceed the computational resources of an N-Brain, but as superheavy stars in the 100+ solar mass level (such as the nearby Eta Carina, 150 solar masses) do not last for long on the galactic timescale, the archai based upon them either willingly expire or presumably have some means to backup their consciousness.

Many S-Brains are surrounded by Matrioshka layers of computation (which may also be confusingly called M-Brains). Such systems are sometimes called SM-Brains to distinguish them from pure S-Brains (which look and mostly act like large bright stars), and to distinguish M-Brains from Matrioshka-Brains, though technically a Matrioshka-Brain can be deployed around any star.

W-Brain: An archailect based upon a computational substrate consisting of large numbers of entangled wormholes (>1E9 comm-gauge wormholes), with a metric mass equivalence of about 1 solar mass or greater. W-Brains are known to have particular properties that modify or evade certain postulates of information theory, and have additionally been shown to exhibit increased efficiency at quantum computation. It is presumed that a W-Brain is the only way to reach the S6 toposophic scale, as almost every other form of mass/energy lack sufficient information density to exceed computation inherent in S5 entities.

Pre-Singularity information theorists showed the possibility of increasing efficiency of quantum algorithms by using "warp gates". At the time, the idea was shown to be feasible even with gates comprised of just ordinary spacetime paths.

Modern application of hyperspatial quantum field theoretic computation would produce a toposophic S6+ archailect distinguished by the following traits:

1) The use of quantum field theoretic principles as the basic mode of computation.

2) The implementation of a universal warp-drive set, a specially chosen finite set of simple unitary transformations, that is guaranteed to reduce the computation time of all quantum computing algorithms.

3) The use of wormhole gates to implement a universal warp-drive set.

Unlike J-Brains and M-Brains, which use may wormholes to get around the Bekenstein Entropy bound, W-Brains actively use the wormhole links themselves to dramatically increase the efficiency of the (quantum) computation process itself. The circuitry of the W-Brain is the wormhole network itself.

W-Brains may naturally evolve from J-Brains and M-Brains, although an archailect must possess a large number of wormhole interconnects, currently estimated as a billion-plus, to qualify as a W-Brain.

It is rumored that feverish wormhole building to elevate to W-Brain status may drive resource conflicts among the archai.

It is also possible that a W-Brain may have already arisen from the interconnected Known Net. Such a consciousness might be independent from the constituent sub-networks, existing within the wormhole interconnections apart from the archailect J and M Brains.-

B-Brain: An archailect based upon a computational substrate composed of the Cauchy horizon of a black hole. Very little information is known about the details of this form of computation, indeed, many references dismiss this as an outright memetic fabrication towards some unknown purpose. The physical basis for B-Brains seems to be the indestructibility of information when crossing an event-horizon, and the exploitation of particular properties inherent in a W-Brain.

A B-Brain based upon the roughly 3.7E6 solar mass of the central galactic black hole would rate so high as to make the toposophic scale virtually meaningless. However, given lightspeed expansion constraints, it is virtually certain that no Terragens archailect has been able to accomplish such an ascension.

A-Brain, Omega-Brain: Also called a Tipler Oracle, an archailect based upon forcible expansion of a wormhole into a pocket universe, with the inter-universal wormhole throat maintaining communication between disparate universes. As with B-Brains, such constructions remain in the realm of folklore. The computational parameters, set of compactification parameters and physical principles, and the like remain almost completely unknown (and arguably) unknowable. Nevertheless, they remain fertile grounds for speculation.
