### Summary of strand quantum theory

Strands provide a microscopic model for wave functions. Wave functions arise as averages of crossing switches. This model allows deriving, from a single principle, the SchrÃ¶dinger equation, the Pauli equation, the Klein-Gordon equation and the Dirac equation. The model explains spin 1/2, fermion behaviour, countable particles, mass and interactions. The model fully agrees with conventional quantum theory and with experiments. Those aspects that go beyond conventional quantum theory agree with experiments as well: strands limit the possible elementary particles and limit the possible interactions to the observed ones. Strands also uniquely fix the masses and mixing angles of elementary particles, and the couplings constants. The strand model thus implies that there is no new physics and no quantum field theory beyond the standard model. For example, strands fully contradict the Clay millennium problem about Yang-Mills theory.

### Testable predictions of strand quantum theory

Neutrino masses have normal order.

No physics beyond the standard model or beyond general relativity occurs.

In nature, there is an upper limit on probabiliy density, given by the inverse smallest volume.

No trans-Planckian effects of any kind occur.

There are no higher (or lower) dimensions.

There is no supersymmetry. Dark matter is not made of unknown elementary particles.

Fundamental constants – elementary particle masses, mixing angles, and coupling constants – can be calculated.

### Qubits

Strands also visualize qubits. The preprint shows the details.

In fact, strands provide a way to visualize the statement by Zizzi about nature: it from qubit. Everything arises from the strand model of qubits.

### The fascination of strand quantum theory

Every electron, every atom, every basketball and every person is tethered.

Everything is connected to everything else.

The universe consists of a single strand.

Strands imply that `every thing' is *made of* `everything'.

### Similar ideas by other authors

So far, apart from the work by Battey-Pratt and Racey, I found no similar ideas in all literature searches I performed. Not even the researchers working on emergent quantum theory published anything similar. But I might have overseen something.

Studying the complement of strands, i.e., the evolution of the space between them, could provide an equivalent alternative. But no model of space has yet achieved a similar explanatory reach.

### Bets and future tests

In science, every statement must be checked continuously, again and again. This is ongoing. A sweeping statement like "strands explain wave functions" must be checked with particular care. If you have a counterargument or notice a missing issue, just send a note.

The numerous experimental predictions and proposed bets listed on this page are precise. They cover all domains of nature and of physics. Finding any single observation falsifying a single prediction of the strand conjecture wins the bet.

In fact, finding *any* alternative, correct and inequivalent description
of wave functions
– or of nature – wins the bet.

It might well be that the similarities between strand gravity and strand particle entanglement can be used to deduce connections between the two effects.

Most interestingly is the following: experiments of tethered asymmetric bodies in slowly flowing liquids should yield estimates for particle mass values.

In the past, models for quantum theory have never been successful. In fact, the whole topic has a mixed image. But if one does not risk making a fool of oneself, there is no progress. Enjoy.
