Three‑Body Kernel (TBK): a reusable kernel for the “not solvable” problem

Three‑Body Kernel (TBK): a reusable kernel for the “not solvable” problem

by Marcus Hermansson | Feb 8, 2026 | "Science", Computer Science & AI, Physics & Cosmology

Three‑Body Kernel (TBK): a reusable kernel for the “not solvable” problem Disclaimer This is not a claim of an analytic solution to the general three‑body problem. This is a kernel + tooling handoff: the clean internal formulation you use when you want to simulate a...
Headsets as Actuators, Part II — Additional Vectors (A–F) and How to Harden Against Them

Headsets as Actuators, Part II — Additional Vectors (A–F) and How to Harden Against Them

by Marcus Hermansson | Jan 21, 2026 | "Science", Computer Science & AI, Engineering & Materials, Medicine, Physics & Cosmology

Context: This is a follow-up to my earlier post on the Venezuela “sonic weapon” rumor and the real vulnerability hiding in headsets. This post is a defensive advisory: it explains the biology, maps additional vector classes (A–F), and lists practical hardening steps....
The Venezuela “Sonic Weapon” Rumor — and the Real Vulnerability Hiding in Headsets

The Venezuela “Sonic Weapon” Rumor — and the Real Vulnerability Hiding in Headsets

by Marcus Hermansson | Jan 20, 2026 | "Science", Computer Science & AI, Engineering & Materials, Medicine, Physics & Cosmology

Disclaimer (important): The “sonic weapon” claim tied to the Venezuela raid is unverified and largely traces back to viral testimony and social media amplification. This post is a physics + security analysis of what could explain the symptom-shape people are...
The Evolving Spacetime Expansion Theory (ESET) — v2.1

The Evolving Spacetime Expansion Theory (ESET) — v2.1

by Marcus Hermansson | Sep 14, 2025 | "Science", Physics & Cosmology

Changelog / Version history – ESET v2.1 Last updated: 1 Dec 2025 What this post isThis article is the plain-English introduction to the Evolving Spacetime Expansion Theory (ESET). It explains the basic idea that spacetime is not just curved but also elastic – it can...
Finessing Einstein: Measuring the One‑Way Speed of Light Without Using Light

Finessing Einstein: Measuring the One‑Way Speed of Light Without Using Light

by Marcus Hermansson | Sep 14, 2025 | "Science", Engineering & Materials, Physics & Cosmology

TL;DR The classic problem: you can’t time a one‑way light trip unless your two clocks agree first. Most ways to make them agree secretly use light. Our rule: no light to set the clocks. Our move: build a home‑made time standard from sound sent through three very...
