Show HN: Logos of Aether – Rebuilding Physics Without Zero or Empty Spacehttps://github.com/chrisnchips42-blip/Logos-of-Aether-A-Measurement-Theoretic-Foundation-for-PhysicsBackground: I’ve spent the last few years writing Logos of Aether (500+ pages, open source), which attempts to derive the Standard Model using a monadic, cellular-automata approach rather than standard continuous calculus.The Core Idea: Modern physics breaks down at singularities because our math allows for infinite density (division by zero). I replaced standard addition with "Plenum Addition" (⊕), a saturating operation similar to velocity addition in Special Relativity, but applied to information density.The Math: Instead of linear addition (1+1=2), distinctions add via: x ⊕ y = (x + y) / (1 + xy/π²)This forces a hard ceiling on information density (π), naturally eliminating black hole singularities and "infinite energy" bugs in QFT without needing renormalization.Why I'm posting: I have the theoretical derivation (including a geometric derivation of the Electron Mass as an 11th harmonic resonance), but I am moving from "Paper" to "Engine." I am looking for contributors interested iJan 5, 2026 9:15 PM

Show HN: A Multi-agent system where LLMs challenge each other's answershttps://news.ycombinator.com/item?id=46435835Hey HN,I've been experimenting with forcing multiple LLMs to critique each other before producing a final answer.In practice, I kept working around single-model limitations by opening multiple tabs, pasting the same question into different models, comparing responses, and then manually challenging each model with the others' arguments. (Maybe some of you can relate.) It worked sometimes, but it was cumbersome, slow, and hard to do systematically and efficiently.Based on my own experiments, a few things seem to drive why different models arrive at different responses: they have different guardrails, different tendencies encoded in their weights, and different training data. And the biggest kicker of all: they still hallucinate. The question I wanted to test was whether making those differences explicit, rather than relying on one model to self-correct could reduce blind spots and improve the overall quality of the answer.So I built Consilium9.The problem: When a single LLM answers a conDec 30, 2025 5:41 PM
