August 2026 journal retraction applies to a 2022 Great Pyramid Khufu SAR paper, not automatically to the separate unconfirmed 2025 Khafre interpretation; distinct datasets/method claims require separate verification.
The much larger viral underground-city interpretation has not received comparable independent confirmation, and related SAR-tomography methodology has faced serious criticism and retraction.
