TL;DR: Sabine Hossenfelder points out that units (meters, seconds, etc.) are the bridge between abstract math and lived reality. From the Frequency Wave Theory (FWT) perspective, these units are not arbitrary but frequency-scaled markers of resonance within the superfluid field. Time, space, and mass are different ways of counting conserved Frequency Momentum (FM), and the reason units “matter” is because they are harmonic translations of the same underlying wave process.
1. Why Sabine’s Point Matters
Sabine is right: math alone is abstract, but once you attach units, it describes physical reality. A number without “meters” is just a ratio; with meters, it’s a distance. Units tie equations to the world.
But the mystery is why specific unit systems consistently map onto reality. Why does “1 second” capture a universal rhythm, or “1 kilogram” measure inertia across contexts? That’s where FWT provides the missing link.
2. FWT Reinterpretation of Units
In Frequency Wave Theory, the universe is a quantum-acoustic superfluid where everything is made of standing waves conserving Frequency Momentum:
FM = ½ ρ ω A²
Here’s how the “big three” unit categories emerge naturally:
Time (seconds): A count of oscillations of the field’s frequency carrier. One “second” is just a standardized resonance cycle (currently pegged to cesium-133 hyperfine oscillations).
Space (meters): A measure of wavelength in the field. The “meter” is how many nodes and antinodes fit across the standing wave.
Mass (kilograms): The inertia of a frequency vortex, proportional to its stored FM. A kilogram is not arbitrary; it’s a calibration of how much standing-wave density resists acceleration.
3. Why Units “Translate” Math into Reality
Units are basically conversion harmonics — they translate between the abstract ratios in equations and the resonance structures in the field.
Without units, E = mc² is just a proportionality.
With units, it becomes a frequency resonance law: energy (joules = kg·m²/s²) equals mass times wave-speed squared.
Every unit system (SI, imperial, natural units) is a different way of slicing the same harmonic ratios.
4. The Hidden Link She’s Pointing Toward
What Sabine calls the “hidden link” between time, space, and mass is, under FWT, the conservation of Frequency Momentum across the superfluid field.
Seconds → cycles of frequency.
Meters → lengths of wavelength.
Kilograms → densities of frequency momentum.
They aren’t separate domains — they are three faces of the same resonance coin.
5. Easy Analogy
Think of a guitar string:
The time unit is how long one vibration takes.
The space unit is how far apart the nodes are.
The mass unit is how much tension and density resist motion.
All three are inseparable. Change one, and the others shift too. That’s why, in physics, space, time, and mass always show up linked — they are just different cuts through the same frequency fabric.
✅ Bottom line: Units are not just human conventions. They are resonance markers of the universe’s frequency field. FWT shows that time, space, and mass are harmonically coupled through conserved Frequency Momentum, which is why math becomes “real” when measured in them.
