# A modification of inertia depending on acceleration relative to the rotating Earth.

A modification of inertia depending on acceleration relative to the rotating Earth.

**Still possible** Answers **1** questionPublished0

## Where it stands

**Still possible** Its tests haven't settled it: one piece of evidence for, none against. It needs two reviews to be accepted.

## What it predicts

- Predicted anomalies of 2.9, −0.9, 20.1, 0.9, 3.2 and −1.3 mm/s for the six early flybys.

## What would rule it out

- Disagreement with well-measured flybys beyond errors.

## Evidence 1 for · none against

[Three of six early flybys reproduced within error; the others off by 1 to 3 mm/s.](https://mysteriesdept.com/mysteries/flyby-anomaly/evidence/EVD0CWYEG34196X/three-of-six-early-flybys-reproduced-within-error-the-others)
