### The strand conjecture on the complete description of nature

When we look at the starry sky, we admire the vast space, the coloured twinkling stars, and the deep blackness. The strand conjecture proposes an explanation for their origin, their properties and their motion. The foundations of what we find around us – particles, space, horizons and colours of everything we see – are explained.

The paper argues that all of modern physics arises, directly and inevitably, from the Planck scale.

Below, the more pedagogical paper and preprints – about particle physics, gravitation and quantum electrodynamics – provide numerous experimental predictions and tests. They cover electric dipole moments, Planck limits, parity violation, additional elementary particles, graviton detection, torsion, new forces, supersymmetry, grand unification, anomalous magnetic moments, glueballs, scalar mesons, neutrino masses, numerous effects beyond the standard model, and dark matter. A detailed list of tests is given on the bet page found by clicking here.

### The standard model from strands

**Simplicity, unity, elegance.**
It is regularly claimed that the standard model is complex, incomplete or
even ugly. The strand conjecture argues the exact opposite: *all* of
particle physics is due to tangled strands fluctuating at the Planck scale.
A *single* fundamental process appears to explain the principle of
least action, the observed interactions and their symmetry groups, the
observed elementary particle spectrum, and the constants describing them.
Over 140 tests and predictions about particle physics beyond the standard
model are given. They agree with all experiments. And so far, no other
approach in the research literature makes (almost) any of these
predictions. An additional aspect is noteworthy: no question about the
standard model of particle physics remains unanswered. In summary, the
explanation of the standard model using tangled strands is
consistent, correct, counter-intuitive,
hard to vary and, above all, complete.

### Gravitation from strands

**50 000 solar masses per second.** Strands provide a
microscopic model for space and horizons. This allows to derive the field
equations of general relativity. In addition, a complete list of over
90 tests of the strand conjecture in the domain of gravitation are
deduced from a single principle. All tests agree with
observations so far.

For example, strands confirm that gravitation – like nature itself
– has a mass to length limit c^{2}/4G, a mass flow limit
c^{3}/4G, a momentum flow or force limit c^{4}/4G and a
luminosity or power limit c^{5}/4G. The limits are given by one
quarter Planck mass per Planck time, or 50 756 solar masses per second
(times c^{-1}, times c or times c^{2}). No observation
ever exceeded or even reached these limits.

But above all, strands also explain the gravitational mass of elementary particles and provides upper and lower limits for the mass values.

Any complete description of nature has to be *strange*. To satisfy
this requirement, the following animation, made by Jason Hise, shows how
black hole rotation is modelled in the strand conjecture. (The flattening
of the horizon is not shown.) With a bit of
imagination you can determine the location of the ergosphere.

### Quantum electrodynamics from strands

**Colours and beauty.** The strand conjecture shows how the
tangle model leads to quantum electrodynamics. Over 40 tests for
the conjecture are given. So far, they are all positive. In particular,
the strand conjecture appears to allow approaching two old challenges: how
to calculate the fine structure constant and how to calculate the lepton
masses – both from first principles. The preprint uses the tangle
model of particles to deduce estimates. The fine structure constant
1/137.036(1) and the lepton masses, in particular the electron mass, are
the ingredients that determine all colours, tastes, smells, sounds and most
shapes around us. In other words: it is argued that tangles of strands
generate all beauty in nature.

**The spinning electron tangle**. Strands are not
observable, only crossing switches are. Every chiral crossing produces an
electric charge e/3. Jason Hise produced an animation for the
spinning electron (though the tangle should not be flattened):

### Cosmology from strands

A preprint on cosmology will appear here in future, to complete the
topic. In the strand conjecture, the universe consists of a single closed
strand that forms the cosmological horizon and also the particles and the
space inside it. Over time, this strand gets more and more tangled. This
description reproduces usual cosmology and leads to numerous tests and
predictions. A few ones beforehand: the universe expands; nothing –
no matter, no radiation and no space – exists beyond the cosmological
horizon; the luminosity of the universe is always limited by
c^{5}/4G; dark matter is made of known matter or black holes or
both; dark energy is not due to unknown or additional fields; the
cosmological constant is small and positive; inflation did not occur; there
are no cosmic strings, no higher dimensions and no non-trivial topology;
there is no bouncing universe; there is just *one* universe.

### Physics background

**Technicalities.** The strand conjecture
reproduces the Lagrangians of the standard model and general relativity,
explains the number of generations and the particle spectrum,
deduces all Feynman diagrams and propagators,
explains the gauge groups U(1), SU(2) and SU(3),
explains the fundamental constants ab initio,
solves the hierarchy problem,
explains neutrino masses without a see-saw mechanism,
solves the strong CP problem,
predicts the validity of the standard model and of general relativity
up to the Planck scale without any intermediate energy scale,
implies that the weak interaction violates parity maximally,
explains the equality of proton and positron charge,
has no problems with anomalies,
predicts no issues with baryogenesis,
has no grand unification,
has no supersymmetry,
has no additional spatial dimensions,
has no inflation, no inflaton and no dilaton,
solves a number of black hole and singularity issues,
implies gravitational waves,
has no dark matter particles,
has a naturally small cosmological constant,
solves various problems about gauge theories,
answers Hilbert's sixth problem,
and explains the principle of least action.

**Particle tangles.**
Images of the three conjectured neutrino tangles:

Note the similarity of the electron neutrino tangle with three loose
strands. This is one reason for its low mass value.

Images of the conjectured tangles for the electron, the muon and the tau:

These tangles, together with the quark tangles and the elementary boson
tangles, appear to reproduce all Feynman diagrams of the standard model.

**Motivation.**
An important motivation has always
been the support for the ailing physics T-shirt industry.
Since decades, the industry has been desperate for new designs.

### Volume VI of Motion Mountain

**History.** A more extensive, more passionate, but also
older and less precise presentation is the original text on the strand
model. It was written as a *research* volume that continues the
adventure of the five *textbook* volumes.
The present edition has been updated with most results
from the above preprints, and it also presents and corrects the errors of the past:
