Why Are Neutrinos Only Left-Handed? QTT’s Time‑Tilt Answer

https://doi.org/10.5281/zenodo.17594186

There is a tiny particle that seems to know its left from its right better than we do.

Every neutrino we’ve ever caught in a detector is left‑handed. Every antineutrino is right‑handed. Nature, in the neutrino sector, appears to have a built‑in handedness bias. The Standard Model just asserts this: the weak force is left‑handed, end of story.

Quantum Traction Theory (QTT) tries to go further. It claims the “left‑only” rule is not an accident of the weak force, but a shadow of a deeper structure: a tilt between the Universe’s own background clock and the time we measure in the lab.

This post has two layers:

• Part I – a layperson’s picture: neutrinos as one‑way messengers of a tilted cosmic clock.
• Part II – the QTT mechanics: how the time‑tilt, capacity flow, and weak gauge loops produce left‑handed neutrinos and sterile right‑handed partners.

Part I – The strange one‑handedness of neutrinos (intuitive version)

1. The odd fact: neutrinos are one‑handed

Most particles we know have two “handed” versions:

• Electrons can be left‑handed or right‑handed.
• Quarks can be left‑handed or right‑handed.

Here “handed” (or chirality) is a bit like a screw thread. If the particle’s spin points in the same direction as its motion, we call that one handedness; if it points opposite, that’s the other.

Neutrinos are different. In every weak interaction experiment so far:

• Neutrinos show up only as left‑handed.
• Antineutrinos show up only as right‑handed.

The Standard Model encodes this in a compact way: the weak interaction is “V–A”, shorthand for “vector minus axial vector”, which mathematically means “I only talk to left‑handed chiral states”. But it doesn’t really explain why Nature made that choice.

2. QTT’s new ingredient: a tilted cosmic clock

QTT starts from a radical but simple idea:

• The Universe keeps time with an Absolute Background Clock (ABC).
• Our lab clocks measure a tilted projection of that background time.

Imagine a clock axis pointing “straight up” in some abstract time‑plane. That’s the ABC. Our lab time axis is rotated by a fixed angle relative to it. QTT argues this angle is

This isn’t just declared. The same factor shows up in:

• neutrino mass‑splitting ratios,
• magneto‑optical Faraday plateaus in solid‑state crystals,
• and the mapping between absolute and laboratory Hubble constants.

In QTT, this tilt angle is a global constant of the Universe.

3. Neutrinos as pure “time‑tilt” packets

Now here’s the key move: QTT treats neutrinos as almost pure packets of this time‑tilt capacity. They are tiny ripples that live mainly along the direction of the tilted time axis, with almost no extra “spatial loop” structure.

Other fermions (electrons, quarks, etc.) are more complicated. They carry both:

• a share of the same tilted time structure and
• a genuine spatial loop of capacity (a little circuit in space), which is where electric charge and color charge live in QTT.

Because a loop can be run in two directions, those particles naturally come with two chiralities: left and right.

But a neutrino, as a pure time‑tilt bundle, only has one way to “align” its spin with the background clock projection that the weak force can see. The other orientation is effectively hiding in the background clock sector, invisible to the weak interaction.

4. What we call “left‑handed neutrinos” is just one projection

From this viewpoint:

• The visible left‑handed neutrino is the part of the time‑tilt packet that does project onto our lab’s weak interaction loops.
• The right‑handed neutrino is still there, but its capacity flow lives almost entirely “inside” the Absolute Background Clock. It hardly touches the lab’s weak force at all. That’s what we usually call a sterile neutrino.

Our detectors, which only talk to the lab weak force, therefore only ever see left‑handed neutrinos and right‑handed antineutrinos. Right‑handed neutrinos exist in the QTT ledger, but as almost invisible, gravity‑only modes.

So the one‑handedness of neutrinos stops being a weird special rule bolted onto the Standard Model, and becomes a consequence of how the Universe’s own time axis is tilted relative to our lab time.

Part II – The QTT mechanics: chirality from time‑tilt and capacity

1. Standard Model baseline (what we must match)

In the minimal Standard Model:

• The weak charged current is V–A. It couples only to left‑handed chiral fermions and right‑handed chiral antifermions.
• Neutrinos appear only as left‑handed fields in doublets.
• There is no field in the minimal SM.
• All other fermions (charged leptons, quarks) have both left‑ and right‑handed chiral components.

Experimentally, in weak processes:

• All neutrinos are left‑handed.
• All antineutrinos are right‑handed.

QTT must reproduce this pattern, not throw it away. The question is: can we see it as an orientation effect relative to the time‑tilt?

2. Time‑plane, clock tilt and the QTT chirality label

QTT introduces:

• an Absolute Background Clock ,
• a lab clock ,
• a fixed tilt angle between them, with projection

This same is measured independently in the neutrino sector via the QTT relation

which matches global oscillation data at the percent level.

We encode the tilt direction as a unit vector in the extended time direction. For a given fermion, QTT defines a chirality label

where is the spin direction projected into the relevant three‑dimensional subspace. In the ultrarelativistic limit, coincides with the usual helicity, and therefore with the observed left/right assignment in weak processes.

3. Neutrinos as pure clock‑tilt capacity bundles

QTT’s key structural claim is that neutrinos are almost pure clock‑tilt capacity bundles:

• Their capacity flow is dominantly along the ABC ↔ lab time‑tilt direction, with negligible independent spatial loop.
• They are excitations of the mismatch between ABC time and lab time, not self‑contained currents looping in space.

Weak interactions are encoded in QTT as handed twists of capacity around Planck‑scale gauge loops on the QTT dial. To couple a neutrino to such a loop, its spin–tilt orientation must match the sense of this twist.

Mathematically: only one sign of produces a nonzero overlap with the weak gauge loops. The QTT chirality that matches the weak twist is precisely what we call the left‑handed neutrino in the lab.

4. The right‑handed neutrino as an ABC‑only capacity mode

The opposite orientation, , still exists in QTT, but its capacity flow sits almost entirely in the Absolute Background Clock sector:

• It has essentially no projection onto the lab’s gauge loops.
• It couples only via gravity and endurance currents (capacity exchange with the background).

This is QTT’s version of a sterile right‑handed neutrino:

• It is there in the capacity ledger.
• But it is effectively invisible to the and bosons in the lab sector.

The observed fact that neutrinos in weak processes are always left‑handed is then explained by a simple statement:

Our detectors only see the lab‑projected orientation of the clock‑tilt bundle. The opposite orientation is confined to the ABC and shows up, if at all, only through gravitational effects or tiny mixings.

5. Why other fermions automatically have both chiralities

Charged leptons and quarks in QTT are not pure time‑tilt modes. They are space‑plus‑time capacity loops. In addition to sharing the tilted time structure, they carry a genuine spatial closed loop of capacity around Planck‑geometry cycles. That loop is what we usually encode as electric charge, color, etc.

• A spatial loop can be traversed in two orientations. In spinor language, this gives two independent chiral components. In QTT language, it’s two ways to wrap capacity around the loop.
• The Higgs/capacity ledger term couples these two orientations, producing a Dirac mass that links left‑ and right‑handed channels.

Therefore, fermions with genuine spatial loops (electrons, quarks, etc.) naturally come with both and . Neutrinos, being dominantly time‑tilt bundles without their own spatial loop, have only one lab‑visible orientation; the other orientation hides in the ABC.

6. Small neutrino mass as mixing with the ABC mode

Finally, QTT attributes the small but nonzero neutrino masses to a slight mixing between:

• the lab‑active left‑handed neutrino, and
• the ABC‑only sterile right‑handed mode,

through higher‑order capacity bundles.

This mixing is governed by the same time‑tilt angle and by the capacity rules (A1, A6, A7). It naturally produces:

• a tiny neutrino mass scale, and
• the observed ratio ,

while keeping the right‑handed component essentially sterile in all weak processes.

Conclusion – Left-handed by geometry, not by decree

In the Standard Model, the left‑handedness of neutrinos is put in by hand: the weak force is V–A, and that’s that.

In QTT, the same observed pattern emerges because neutrinos are special: they are the cleanest excitations of the Universe’s tilted time axis. Only one orientation of that clock‑tilt bundle overlaps with the weak loops in our lab sector; the opposite orientation is hidden in the Absolute Background Clock sector and behaves like a sterile right‑handed neutrino.

What looks like an arbitrary “left‑only” rule in the weak interaction becomes, in this picture, a geometric fact about how time itself is tilted between the Universe’s ledger and our detectors.

Neutrinos, in short, are not just shy particles. They are the messengers of the Universe’s secret time geometry—and they only ever show us their left hand.
