Why Phase-Lag Interferometry Could Change Physics — Testing HDIF through measurable optical delays.

The Goal

Phase-lag interferometry aims to detect tiny frequency-dependent delays in geometric response — the cleanest experimental signature of curvature–memory coupling.

The Prediction

HDIF predicts that when light interacts with a memory-bearing interface:

• the phase shift won’t match classical GR responses

• the delay will depend on frequency

• the effect will be small but measurable

Why This Matters

If the measured phase-lag curve matches the HDIF prediction, that would be:

• the first direct evidence that spacetime interfaces store memory

• a measurable unification signature

• a falsifiable test that mainstream theories cannot replicate

Why Interferometers Are Ideal

They provide:

• picometer-scale sensitivity

• controlled frequency scanning

• clean isolation for memory-effects

This is HDIF’s most accessible early validation pathway.
