Levengood–Haselhoff vs Grassi (crop-circle science dispute)
concept
Scientists have openly fought over whether crop circles show real strange energy effects or just bad data.
Who they are
A published scientific dispute over crop circles between researchers Levengood and Haselhoff on one side and Grassi and colleagues on the other.
What they do
The engine logs both sides and treats the anomaly claim as contested, not settled.
How it works
Levengood claimed the crops showed swollen and burst plant cells and altered germination suggesting microwave or plasma effects, and Haselhoff claimed a specific energy pattern, but Grassi and colleagues published a rebuttal saying the results were misrepresented and one key spiral lacked the claimed pattern, while the journal in turn rejected Grassi's rebuttal as questionable.
Why it matters
It matters because the engine keeps this held as genuinely disputed, noting the anomaly claim does not survive the rebuttal cleanly.
The engine's record — word for word
Anomalous-Phenomena raw-data extraction (2026-06-11): BOTH SIDES logged. Levengood (Physiologia Plantarum, 1990s) claimed pulvini node-elongation/exploded cells + altered germination (microwave/plasma); Haselhoff claimed a 1/r² EM profile. Grassi-Cocheo-Russo published a peer rebuttal (statistical misrepresentation, discarded results, the Beckhampton spiral lacked 1/r²); Physiologia Plantarum rejected Grassi's rebuttal as 'questionable science.' Held CONTESTED — the anomaly claim does NOT survive the rebuttal cleanly. [DOCUMENTED dispute, both directions]
