Wavelengths
The framework has one medium and three structural modes. Everything we call radiation — light, radio, X-rays, microwaves, gamma rays, gravitational waves, neutrinos — is the same medium oscillating, distinguished only by frequency and by which polarisation of the fabric is doing the oscillating. The framework's account of wavelengths unifies every kind of wave in physics into one continuous spectrum across thirty-seven orders of magnitude.
The fabric's spectrum
The fabric supports a continuous spectrum of radiative-mode frequencies. The lowest possible frequency is the mass-gap ω₀ ≈ 3.32 × 10⁻¹⁶ radians per second — the natural fabric oscillation frequency, set by the ratio of the framework's restoring and inertial moduli through ω₀ = √(ε/α). The period at this frequency is about 600 million years, and the wavelength is about 29 megaparsecs. Below this frequency the fabric cannot oscillate as a propagating wave. The mass-gap is the floor.
Above the mass-gap, the fabric supports waves of every frequency in a continuous spectrum. The dispersion relation ω² = ω₀² + c²k² gives one wave frequency for every wavevector above the natural cutoff k₀ = ω₀/c. As frequencies climb, wavelengths shrink. The spectrum extends upward without an intrinsic upper limit — the highest-frequency fabric ripples sit near the soliton-formation scale ω_TCM ≈ 8.85 × 10²¹ radians per second, where one quantum of fabric oscillation carries the natural fabric mass energy m_TCM c² ≈ 5.82 MeV.
That continuous spectrum from the mass-gap to the soliton scale spans thirty-seven orders of magnitude in frequency. Visible light occupies about one part in 10¹⁵ of this spectrum.
The three structural modes
At any frequency, the fabric can oscillate in three distinct structural ways. Each is a different polarisation of the same medium.
The phase-winding mode oscillates while carrying a phase current J^μ — the same current that gives charged solitons their electromagnetic character through the coupling α_J. Phase-winding modes are what conventional physics calls photons. Across the spectrum these are radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays — the entire electromagnetic spectrum is one structural mode of the fabric at different frequencies.
The framing-structure mode oscillates with winding in the framing field γ — the same structure that gives heavy-mediator transitions their character through the coupling α_W. These are what conventional physics calls the carriers of neutrino-like behaviour at low energy and W/Z-boson-like behaviour at high energy.
The density mode is the fabric's scalar oscillation — the magnitude n itself oscillating with no phase or framing winding. Density modes are what conventional physics calls gravitational waves. LIGO detects them in the kilohertz band. LISA will detect them in the millihertz band. The cosmic background of density modes near the mass-gap ω₀ is the next observational frontier.
Three modes, one fabric. Every frequency in the spectrum supports all three modes simultaneously. What conventional physics calls "different forces" — electromagnetism, the weak interaction, gravitation — are different structural modes of the same medium.
The familiar landscape
Here is the fabric's spectrum as it shows up:
Band Frequency Wavelength Conventional name
Mass-gap 10⁻¹⁶ rad/s 29 Mpc cosmic ripples / graviton scale
Ultra-low 10⁻¹ rad/s 10⁹ m LISA-band gravitational waves
Sub-kHz to kHz 10⁰ – 10⁴ rad/s km LIGO-band gravitational waves
Radio 10⁶ – 10⁹ rad/s mm – km Radio waves, microwaves
Infrared 10¹³ rad/s μm Heat
Visible 2.7 – 4.7 × 10¹⁵ 400–700nm Light (red to violet)
Ultraviolet 10¹⁵ – 10¹⁶ 10 – 400 nm UV
X-ray 10¹⁸ rad/s 0.01–10nm X-rays
Gamma 10²¹ rad/s < 10 pm Gamma rays
Soliton scale 10²² rad/s 34 fm Natural fabric energy
Each band is a different stretch of frequency. All are the same medium oscillating.
Why frequency matters: energy per quantum
The fabric ripples at every frequency, but each frequency has a different energy per quantum. One ripple in the fabric at frequency ω carries energy ℏω — the framework’s canonical quantum of fabric oscillation at that frequency. Higher frequency means more energy in a single quantum. Lower frequency means less. This single fact is what makes different bands of the spectrum behave so differently when they meet matter.
Consider what it takes to disrupt a catalogue soliton — to knock an electron free from an atom, to break a molecular bond, to damage a strand of DNA. Each of these disruptions has a characteristic energy scale set by the α_J phase-current coupling that binds the catalogue solitons together. Atomic binding energies sit in the electron-volt range; molecular bonds in similar territory; nuclear binding in the mega-electron-volt range. These are the natural energy thresholds the fabric has to clear to do meaningful work on matter.
A radio-wave quantum at frequency 10⁹ rad/s carries energy ℏω ≈ 10⁻²⁵ joules — roughly a millionth of an electron-volt. That is far too small to disrupt any catalogue soliton binding. Radio waves can be absorbed in bulk to warm a substance, but no single radio-wave quantum can free an electron or break a bond. The fabric is rippling; the catalogue solitons barely notice.
An X-ray quantum at frequency 10¹⁸ rad/s carries energy ℏω ≈ 10⁻¹⁶ joules — about a thousand electron-volts. That is well above atomic binding scales. A single X-ray quantum can knock an inner-shell electron clean out of an atom, ionising it. Build up enough of these collisions in living tissue and you damage cells. This is not because X-rays are a different kind of thing than radio waves — they are the same fabric oscillating — but because the quantum energy at X-ray frequencies sits above the catalogue binding scale, where radio quanta sit far below it.
The same logic explains every band. Microwaves are tuned to resonate with rotational and vibrational modes of catalogue-soliton arrangements in molecules — that is why they heat food efficiently. Infrared quanta carry just enough energy to excite low-energy electronic transitions and molecular vibrations — that is why infrared is “heat” to our skin. Visible-light quanta carry enough energy to trigger specific state changes in the rhodopsin solitons of the retina — that is why we see. Ultraviolet quanta carry enough energy to break some molecular bonds — that is why UV damages skin. Gamma-ray quanta carry enough to disrupt nuclear catalogue configurations — that is why gamma radiation is the most penetrating and most disruptive.
The threshold for any observed effect is the same question every time: does ℏω at this frequency exceed the binding scale of the catalogue solitons being hit? The answer determines what the fabric ripple can do. Same fabric, same medium, same physics — different points on the dispersion curve, vastly different consequences.
Why we see only 400 to 700 nanometres
The visible band of light is about one octave wide — frequencies span a factor of two from red to violet. This narrow band is what our eyes evolved to detect, and the choice is not arbitrary.
Our Sun's surface, at about 5,800 kelvin, emits phase-mode fabric ripples that peak around 500 nanometres (yellow-green). Earth's atmosphere has a transparent window in roughly the 400 to 700 nanometre range — most other wavelengths are absorbed or scattered before reaching the ground. Living things that could detect phase-mode ripples in the band most available from our Sun through our atmosphere had a survival advantage. Eyes evolved to that band by selection.
There is nothing fundamental about the band itself. A creature evolving around a different star, or living under a different atmosphere, would have eyes tuned to a different range, and would call that "the visible spectrum." Our 400 to 700 nanometre band is local circumstance, not a property of the fabric.
The fabric is rippling at every frequency in every mode all the time, everywhere. We just evolved a detector for one specific band of one specific mode.
How detection actually works
Every detector ever built is a translator. It takes fabric oscillations in some band or mode we cannot directly perceive, and converts them into a signal we can register — usually a visible-band phase-mode ripple our eyes can see, or an electrical signal we can read.
The eye is a translator. Visible-band phase-mode ripples hit rhodopsin molecules in the retina. Rhodopsin is a closed-ring soliton arrangement with internal energy levels. When a visible-frequency ripple hits, it triggers a state change in the rhodopsin solitons. The state change opens an ion channel, which generates a neural signal. Your eye converts one type of fabric ripple into another.
A radio telescope is a translator. Radio-band phase-mode ripples induce currents in the antenna's metal structure. The currents become electrical signals that get amplified and recorded.
LIGO is a translator for density-mode fabric ripples. Laser interferometry measures the stretching and squeezing of space (the density-mode polarisation of the fabric) as gravitational waves pass through. The density ripple changes the relative path length of two laser beams; the change shows up as a phase shift in the interference pattern; the phase shift is converted to an electrical signal; the signal is recorded as a chirp we can plot and analyse.
A UV lamp on fluorescent ink is a particularly clean example. UV phase-mode ripples — just above visible frequency — hit the dye molecules in the ink. The molecules' internal solitons absorb the UV energy and jump to higher internal states. Those states are unstable, so the solitons drop back down through intermediate levels, emitting fabric phase-mode ripples on the way — but at visible-band frequencies. Your eye sees the re-emitted visible light. The fluorescent ink is a frequency translator: UV in, visible out, mediated by a soliton state cascade.
This is why a UV lamp can reveal markings on banknotes, biological samples, or stage props that are invisible to the naked eye. The markings are there in the visible-light view; the UV input provides the right frequency to activate the fluorescent translator, which then emits in the band our eyes detect.
Every detector follows the same pattern: take fabric oscillations in one band or mode, run them through a translator that responds to that band, produce a signal we can perceive.
The fabric is bigger than what we see
For most of human history, the visible band was all we had. Every painting, every observation of nature, every record of the sky was made through eyes tuned to a single octave of a single polarisation in a tiny corner of the spectrum.
The story of physics since 1600 has been the slow extension of our reach into the rest of the spectrum.
Newton in 1672 splits visible light into colours, demonstrating that even our narrow band has internal structure.
Herschel in 1800 discovers infrared by feeling warmth beyond the red end of a prism's spectrum. The first detection outside the visible.
Ritter in 1801 discovers ultraviolet by watching it darken silver salts. The band above visible.
Hertz in 1888 generates and detects radio waves. Much lower frequencies, the same medium.
Röntgen in 1895 discovers X-rays. Much higher frequencies.
Through the twentieth century, gamma rays, the entire microwave band, and the full electromagnetic spectrum get mapped.
LIGO in 2015 detects density-mode fabric ripples for the first time. The first observation outside the phase-winding family entirely.
Future neutrino observatories, cosmic-microwave-background polarisation studies, pulsar timing arrays — these will extend our reach further into the framing-mode signals and the cosmic-scale density-mode background near the fabric's mass-gap.
Each discovery has revealed more of what the framework was always saying was there. One medium, oscillating at every frequency, in three structural modes, everywhere. We are slowly building detectors for what the universe is always doing.
What this means
The world is much richer than our eyes can perceive. Right now, fabric ripples are passing through you at every frequency from the cosmic mass-gap (period 600 million years, wavelength 29 megaparsecs) up through the soliton scale (period 10⁻²² seconds, wavelength 34 femtometres). They are in all three modes: phase winding (light), framing structure (heavy-mediator carriers), and density (gravitational ripples).
Your eyes catch one tiny octave of the phase-winding mode. Your skin feels a slightly wider band of the same mode as heat. Your cells exchange signals through specific catalogue-point state changes. Your body is built from closed-ring solitons of the same fabric that is doing all the rippling.
There is no separate "space" through which radiation moves. There is no separate "field" that carries light versus gravity versus neutrinos. There is one fabric. Everything is fabric, oscillating in different modes at different frequencies. The visible band is one thin slice; everything outside it is the same medium doing the same thing at different rates.
The framework names the medium, the modes, and the spectrum. The rest of physics is the slow expansion of our detector reach into bands we cannot directly see.
