Late Great Fall

Some date the decline of the English language to the Great Vowel Shift, but I believe the fall started with the Late Heavy Bombardment.

clue:

The Great Vowel Shift transformed Middle English to Modern English. The Late Heavy Bombardment was an episode in the formation of the solar system.
