 However,
in demonstrations, human teams have struggled, without
success, to reproduce designs as geometrically complex
as those seen in fields. Certain formations have appeared
within one night; the short amounts of time, the geometric
calculations, and the methods of bending and weaving the
plants are clearly beyond human capabilities.
Work by laboratories on circle-affected crops has
shown biological changes taking place at a cellular level,
and speculation about the causes includes microwave energy,
sound waves, and electromagnetic forces. Other physical
tests have shown anomalies that aren't replicated in man-made
experiments. |
