Need for physical excavation to verify findings

Only excavation can confirm or refute satellite scan findings. Existing shafts on the Giza plateau might connect to deeper structures. Ground-penetrating radar could verify some findings within a 20-meter range. Egyptian authorities have been skeptical of previous scan claims. Italian researchers using satellite radar imagery claim to have identified large underground structures beneath the Great Pyramid, but experts say only ground-truthing (excavation or drilling) can confirm whether these are real structures or anomalies.
