Divergence Value

Divergence is an objective measure, quantifying a feature of gravity that varies between worlds, with its zero point set on the world line where the first Divergence Meter was constructed.

"First, a foundational measurement of local gravity is taken and then used as a value of reference, wherein after time traveling, the meter generates a local gravitational sine wave, reproducing the tenets of the Kerr Black Hole theory, then measuring gravity via the onboard gravitational distortion apparatus in order to calculate the rate of variation."

Fluctuations in divergence value after the sixth decimal doesn't cause the physical world to entirely reconstruct.
