### Clarification

Since five decades, the 9 lines summarizing textbook
physics as a combination of general relativity and the standard model
(with massive mixing Dirac neutrinos) provide
a complete theory of nature. The 9 lines thus *seem* to be a candidate
for a "theory of everything." However:

(1) Even though the 9 lines contain all natural sciences, they don't contain
"everything".

(2) There are too many lines.

(3) The last 4 lines with their seemingly arbitrary choices for coupling
constants, particle masses and more are not understood.

Therefore, the 9 lines are a complete theory, but not a unified one.

A "theory of everything" does not exist, as explained below.
A *unified* theory does.

The strand tangle model is a candidate for a
unified description of motion:

(1) Strands provide, like the 9 lines, a *complete* description of motion,
i.e., a complete description of all natural sciences - and of nothing outside
natural science.

(2) Strands are based on a *single* statement or line, the
*fundamental principle*.

(3) Strands *explain* the last 4 lines with their seemingly
arbitrary choices for coupling constants, particle masses and more.

The single fundamental principle is: *Crossing
switches of otherwise unobservable, fluctuating strands with Planck radius
define all observable processes in nature.* Equivalently: The Dirac
trick at the Planck scale describes nature completely.

The consequences: Particles are tangles of fluctuating strands. Wave functions are blurred crossing densities. Space is a blurred network of fluctuating strands. Gravity and curvature are blurred inhomogeneous strand networks. Horizons are blurred weaves of strands. Motion minimizes crossing switches.

Publications are at graduate student level. Ideas are accessible.

### Plus

The strand conjecture reproduces general relativity and the full standard model, including the particle spectrum, the interaction spectrum and the gauge groups. Read more here.

The strand conjecture predicts to reproduce the values of the fundamental constants: particle masses, mixing angles and coupling constants. This allows testing the conjecture.

The strand conjecture predicts the lack of physics beyond the standard model and beyond general relativity. This implies hundreds of ongoing and future experimental tests.

These and all other predictions derive from the fundamental principle.

All conclusions and predictions agree with experiment.

None of the predictions is made by any other candidate conjecture.

Nothing unexplained is left over in fundamental physics.

### Minus

Calculations of fundamental constants of the standard model are not yet precise.

The strand conjecture cannot predict human behaviour. It is **not**
a theory of everything. Instead, the strand model is
a candidate for a unified description of motion.

### Bonus

No hype possible: No new effects. No myth. Not a paradigm shift. Not a big deal.

No misuse possible: No new power. No new weapons. No secret knowledge. No new age nonsense. No salvation. No eternal bliss. Not mystical. Not magic. Not a holy grail.

Pretty: Just a few lines that fit on a T-shirt.

Simple: A mix of topology, geometry and algebra. Accessible at science student level.

Global: Also implies a simple cosmological model.

**A Tiny Theory.** In fact, as long as experiments confirm
it, the strand tangle model, with its simple fundamental principle, is the
*tiniest* known theory.

### Smurf

The answer to every question about nature is the fundamental principle. Or, equivalently: "The Dirac trick at the Planck scale." The strand tangle model thus leads physicists to talk about nature like the smurfs (puffi/schtroumpfs/Schlümpfe/smurfen) do: they (almost) only use the word "smurf" in their conversation.

Indeed, since the beginning in 1958, smurf has been the acronym for

"**s**trand **m**odel: **u**nified, **r**igorous, **f**inal".

### On names

The strand conjecture promises to be a *unified description of
motion*. 'Unified' means that it describes all motion, with full
precision, with just one principle. A 'description' is the result of
observation. The term differs from the more sensational ones used in
related fields. The expression 'grand unified theory' is used for a group
of older research approaches that were neither grand, nor unified, nor
theories. The term 'final theory' is reserved for titles of mediocre books
and games. Expressions starting with 'super...' are used for unsuccessful
attempts from the past. The term 'world formula' is reserved for
misleading theatre plays – and for calculating the optimal way to
park a car backwards. The term 'theory of everything' is used for
unsuccessful esoteric healing attempts, and for titles of mediocre films.
In contrast, the expression 'unified description of motion' is correct
– so far. It is also sober enough to keep it from ever appearing or
being misused in mass media headlines.
