The Nyquist clock is likely a simple asynchronous settling process.

It is likley asynchronous, determined by the settling time of a vacuum sample. Every other sample takes one clock and settle, while the others sample then settle.   Taking three clocks for one sample to shift twice. The clock just settle to some natural rate.

-1 is minimum, so they move to the center faster than zero, and +2 two moves to the outside, zeros in the center. The sampling continues forever, I would assume, but gets stuck when the zeros pile up. The +2 twos will continue indefinitely in the vacuum, until stuck by some other process moving positive phase.

The density of the vacuum would be Higgs, by definition, and they are likely packed, so the shifting ot the +2 hits another group of +2 and we get the 'well' effect around each Higgs, and the halwave is formed. Smaller disturbances get swamped until the Higgs settle.

Likely empty space has already been cleared of the +2 values, empty space is already curved.
