Eclipses & the August 12, 2026 Total Solar Eclipse

The claim

“Eclipses work in any model and predictions are just pattern-matching.”

What is true

Eclipse dates can be forecast from repeating cycles without knowing anything about gravity or shape. The Babylonians did it.

What is measured

The April 2024 total eclipse’s path was forecast years ahead to the minute and the mile. That is impossible without a full 3-D Sun–Earth–Moon model.

What would show this is wrong

an eclipse occurring off the predicted Sun–Earth–Moon alignment, or one that orbital geometry could not forecast.
