Where in that link does it prove that the movement is caused by the rotation of the earth rather than the overhead rotation of the stars?
Tom, again, please listen. The scientific method does not work the way you wish. Here's the the outline of the scientific method as applied to FPs.
Hypothesis: The RE rotates. The amount of rotation of an FP can be predicted by formula based on the FP's latitude.
Design: With FPs in both NH and SH, measure the amount (and direction) of the FPs's rotation.
Result: FPs sweep out the expected amounts with the direction in the NH opposite of the SH.
Conclusion: The hypothesis has predictive merit.
Counter-hypothesis. The FE does not rotate. The behavior of FPs is controlled by the rotation of stars overhead.
Analysis: Since the stars rotate in the same direction in both hemidiscs and the FPs behave differently in each hemidisc, the counter-hypothesis failing to predict this behavior is falsified.
RET is the better model in regards to FPs.
