This preprint will make you enjoy physics. All of it. And nature. All of it.

**Abstract.**
It appears possible to deduce black holes, general relativity and the
standard model of elementary particles from one-dimensional strands that
fluctuate at the Planck scale. This appears possible as long as only
switches of skew strand crossings are observable, but not the strands
themselves. Woven fluctuating strands behave like horizons and imply black
hole entropy, the field equations of general relativity, and cosmological
observations. Tangled fluctuating strands in flat space imply Dirac’s
equation. The possible families of unknotted rational tangles produce the
spectrum of elementary particles. Fluctuating rational tangles also yield
the gauge groups U(1), broken SU(2), and SU(3), produce all Feynman
diagrams of the standard model, and exclude any unknown elementary
particle, gauge group, and Feynman diagram. The conjecture agrees with all
known experimental data. Predictions for experiments arise, and the
fundamental constants of the standard model can be calculated. Objections
are discussed. Predictions and calculations allow testing the conjecture.
As an example, an ab initio estimate of the fine structure constant is
outlined.

**Elegance.** It is sometimes claimed that the standard model is 'ugly'. In contrast, the
preprint proposes that the standard model is incredibly simple, unique, without
alternative, complete, and surprisingly elegant: the full, unmodified standard
model is due to strands fluctuating at the Planck scale. A *single*
fundamental process appears to explain the observed interactions and their symmetry
groups, the observed elementary particle spectrum, and the constants describing
them. Here is a shorter preprint on the standard model only:

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

**Tests.** Numerous experimental predictions - about electric dipole moments, graviton
detection options, parity violation, additional elementary particles, new forces,
supersymmetry, anomalous magnetic moments, glueballs, scalar mesons, and many more -
provide tests of the tangle conjecture.

**History.** A more extensive, more fascinating, but also older presentation
(the tangle assignments for the gluons and leptons appear to be *wrong*, in retrospect) is
the original text given here:

**Naming.**
The tangle model appears to be a *complete description of motion*.
This expression is to be preferred to other, more sensational terms that are
used in other fields.
Nowadays, the term `theory of everything' is reserved
for esoteric healers, the term 'final theory' is reserved for tabloids, and the term
`world formula' is used for calculating the optimal way to park a car
backwards.

**Motivation.**
Some thoughts are found on my blog on fundamental physics and tangles and on my blog on teaching.
Past discussions about the strand model can be found on this page. An important motivation
has always been the support for the ailing T-shirt industry.
