### These research papers are about enjoying physics and nature. All of it.

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 motion and their properties. The foundations of what we find around us - space, particles, horizons and colours of everything we see - are explained.

**Extension 1.** This shorter preprint will make you enjoy
the standard model.

**Simplicity, unity, elegance.**
It is sometimes claimed that the standard model is complex, incomplete or
even ugly. In contrast, the strand conjecture argues that the standard model is
simple and complete: the full, unmodified standard model 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. This explanation agrees with all experiments.
The explanation of the standard model using strands is almost incredibly
simple, complete,
surprisingly hard to vary, and truly elegant.

**Extension 2.** This preprint tells how strands induce
gravity - and additional results.

**50 000 solar masses per second.** As strands confirm,
gravitation - like nature itself -
has a mass to length limit c^2/4G, a mass flow limit c^3/4G, a momentum flow limit c^4/4G and a 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 reached these limits.
The momentum flow limit is usually called the ** maximum
force**.

**Tests.** The papers provide numerous experimental predictions
about electric dipole moments, Planck limits, graviton detection, parity
violation, additional elementary particles, torsion, new forces,
supersymmetry, anomalous magnetic moments, glueballs, scalar mesons,
effects beyond the standard model, and dark matter.

**Betting.** The description with strands is called a
** conjecture** throughout. But in fact, it is more
than that: the strand conjecture is a

**on the correct description of nature. For this reason, the preprints provide extensive lists of predictions, as comprehensive as possible, that allow falsifying the model.**

*bet*The author is betting since 2014

– that *no deviation of any kind* will be detected
from quantum field theory or from the standard model with massive neutrinos,

– and that *no deviation of any kind* will be observed
from general relativity at sub-galactic distances,

– and that quantum gravity effects will remain *as hard to detect*
as ever,

– and that the particle spectrum and the interactions, with their gauge groups,
*are determined* by specific tangle families and their deformations,

– and that the fundamental constants *are calculable* from strand
fluctuations of particle tangles at the Planck scale.

The chain of 'and' operators is intended. In 2019, the majority of researchers disagrees with the bet. Just nature appears to agree.

**Background.**
The blog on research about
fundamental physics and tangles tells more.
An important motivation has always been the support for the ailing
T-shirt industry.

**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
started in the five *textbook* volumes.
The first tangle assignments for the Higgs, for the gluons and
for leptons appear to have been *wrong*.
Currently, the text is being corrected and updated with the
results from the above paper and preprints.
