Garrett Lisi

Antony Garrett Lisi (born January 24, 1968), known as Garrett Lisi, is an American theoretical physicist. Lisi works as an independent researcher without an academic position.

Lisi is known for "An Exceptionally Simple Theory of Everything," an unpublished preprint paper proposing a unified field theory based on the E8 Lie group, combining particle physics with Einstein's theory of gravitation. The theory is incomplete and has unresolved problems. The theory has been extensively criticized in the scientific community.
