This preprint is written to make you relish physics. 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.

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, and astonishingly beautiful: the full, unmodified standard model is due to strands fluctuating at the Planck scale.

When we look at the starry sky, we admire the vast space, the coloured twinkling stars and the deep blackness. The preprint proposes a full explanation for the colours of everything we see - including the origin of the fine structure constant. The proposal also appears to explain the origin, motion and details of space, of particles, and of horizons.
