Atomic Tick Processing Constant: First Principal Evidence of Physical Spacetime

In this work we recognize that within the universe's frame there are only two perfect observers: Reference and Local. Reference observers are constant, first-principal, independent measures that apply universally. There are currently only two: the speed of light, and the atomic tick rate in a vacuum far from mass.

Because κ — the per-atom tick constant — is universal, it applies as both time and space. In this we recognize that time and space are the same thing. The only things that exist are things and between things.

From this we measure the length of proton mass — half the proton's Schwarzschild radius — in order to convert mass into length. We use that length to derive the tick rate at any point, and from that tick rate we define velocity.

In this way, from minimal data, we can calculate multi-body orbits from a radius and a distance, predict mass from known gravitational measurements, and do it all without ever invoking a gravitational constant or a mass unit. Count the protons. Measure the distance. Divide. That is gravity.

The geometry of General Relativity lives in atomic processing. GR works as well as it does because it is a faithful copy of this physics, operating one level of abstraction above it.
