What chemical discrepancy proved fatal to the Tidal Hypothesis for solar system origins?

Answer

The resulting planets were predicted to be composed largely of elements with higher atomic weights.

Mathematical analysis showed that the material ejected from the Sun, which is overwhelmingly light elements like hydrogen and helium, would result in planets composed primarily of elements with higher atomic weights, indicating a compositional mismatch.
