In standard physics, spin is treated as an intrinsic property of a particle. In PT it is not a property at all. It is a consequence of geometry & observation.
Imagine a photon as a glowing 1P ball (🥎) ejected from the Unobserved State (ΦN). Instead of breaking into pieces, it stretches, forming a 2P Phield Phibre. This stretched entity still contains 100% of the original, just elongated into a thread.
Each end cap of this thread is one half of the original point:
One cap is ⁻1
One cap is 1⁺
Viewed from either end, these caps appear as two identical "particles," but each carries opposite half-spin. This is how spin emerges in PT. Not as an intrinsic particle property, but as a visual effect of observing opposite ends of the same stretched photon.
Another way to see this is as a tail, body & head, all part of 1 structure:
The ⁻1 (tail) has half a spin in a scalar opposite direction away from the 1⁺
The 1 (body) has no spin
The 1⁺ (head) has half a spin in a scalar opposite direction away from the ⁻1
All bodies (the 1) in PTST have no spin. All head & tail / end cap pairs (⁻1, 1⁺) have opposite half spin. This is the symmetry & balance of the ternary.
Half-spin refers only to orientation (180°). It does not mean ⁻1, 1, or 1⁺ are fractions. All three are whole and equal as 1.
(Note: In PT there are no "particles." What we call Phenom are vector-point intersections of Phibres. They are not discrete objects but projection points that can acquire Phress.)
We tend to think of polarity as simply + and -. But polarity can't exist without a body connecting the two poles. Saying you have a North Pole and a South Pole but no planet between them is meaningless. Even at the quantum scale, a body is required.
This is why PT uses PTTP throughout. Every component has the full ⁻1 ←1→ 1⁺ structure. The ⁻ and ⁺ symbols represent scalar direction or orientation such as left & right, up & down, front & back. You can equally express it without polarity symbols as simply ←1→.
In a universe with no fixed up or down, the orientation of any ternary state is undefined until observed. Imagine floating in space with a light switch in front of you. There is no universal up or down, so whether the switch is up/off or down/on depends entirely on your position relative to it.
Now imagine 1000 switches all aligned the same way. The moment you establish your orientation relative to one, the moment you know that switch is up, you instantly know the orientation of all 1000. Nothing flipped. No signal was sent. You simply know where you stand & the structure does the rest.
This is how orientation resolves in PT. The Phibre always alternates ⁻1, 1⁺, ⁻1, 1⁺ consistently along its length. What observation collapses is simply which end you are reading from. Once that is known, everything is instantly & consistently knowable across the entire Phenomena.
This points toward PT's broader view of entanglement. Not as a special condition between carefully prepared particle pairs, but as the default state of a structurally consistent universe. See Cotter Pin & Axle for more.
