Quantum field theory is the best physical theory created by humans. It predicts the anomalous magnetic moment of the electron to twelve decimal places. It also predicts vacuum energy with an error of $10^{120}$ times.

In 1917 Einstein introduced the cosmological constant $\Lambda$ to hold the Universe from expanding. In 1929, after Hubble's discovery, he called it "the greatest blunder." In 1998 two teams of astronomers discovered that the expansion is accelerating — and $\Lambda$ returned. The observed value:

Standard quantum field theory gives $\Lambda_{\text{QFT}} \sim M_P^4$, i.e. unity in Planck units. The discrepancy — 120 orders of magnitude. This is the largest mismatch between theory and experiment in the history of physics.

Each of the existing approaches — supersymmetry, the anthropic principle, sequestering — explains part of the suppression. None explains everything. And none answers the simpler question: why is $\Lambda > 0$ at all?

UHM answers both questions. The positivity of $\Lambda$ is a theorem [Т]. The smallness follows from six proven mechanisms [Т] and a spectral formula [Т]. The final estimate: $\sim 10^{-120 \pm 10}$ [С]. Without fitting.

The Standard Model of particle physics describes everything we have observed in accelerators over the past seventy years. For this it is respected. But it has a small awkwardness that is usually placed at the end of a lecture course or in a footnote: all fermions exist in three copies — and there is no explanation for this.

Electron, muon, tau lepton. Three particles with identical quantum numbers — simply 207 and 3477 times heavier respectively. The same with quarks: u/c/t (up), d/s/b (down). All visible matter — atoms, planets, you, the reader — consists almost exclusively of first generation particles. The second and third exist, are unstable, appear in accelerators and in the early Universe. Why three, not two or five?

The standard answer: "We measured three. So there are three."

This is not an answer. This is an inventory.

In UHM the answer is a theorem. And it is derived from the same Fano plane that organized 21 types of experience in post 2. That same seven-point construction, seven lines — now explaining not qualia, but the physics of particles.

Why do we live in three spatial dimensions and one temporal dimension?

The standard physicist's answer: "Because that's how the world is structured." The standard philosopher's answer: "It is a transcendental condition for the possibility of experience" (Kant, 1781; translation: "I don't know, but it sounds authoritative"). The standard string theory answer: "There are actually ten, it's just that six are compactified." Why exactly six are compactified — a separate question, which also has no answer.

In UHM the answer is a theorem. The seven dimensions of a holon decompose into three classes, and this partition dictates 3+1. Not because "it is convenient," but because the algebra leaves no alternatives.

Below — how this works, where time comes from, and why it does not exist at all as a "flow."
