The Drain Hypothesis is a speculative interdisciplinary paper by Lee Sharks with TACHYON support.
It asks whether hypothetical deep ancient construction near the Nile could have breached confining layers, altered groundwater flow, reduced shallow water availability, and amplified vegetation–rainfall feedback during Saharan drying.
The mechanism depends on unverified claims about deep structures beneath Giza and on unknown hydraulic gradients and magnitudes. Established archaeology confirms internal pyramid features, not the proposed deep network.
The Atlantis material is an operative literary reading rather than historical or geological evidence. The paper states falsifiable tests but does not establish the mechanism.
