Crop circles, also any other regular, interferences, fractals, or combined pictures are as well as only a tiny fraction of this phenomenon, that may perhaps occur only thanks to very rare interactions of several coincidences, under conditions that are not yet sufficiently explained, can be only very approximately estimated and simulated in laboratory or computer. Considerable influence just before bending stalks to the ground, may play a humidity - even slight showers or drizzle, or even the morning dew.
I-crop ang bilog, din ng anumang iba pang mga regular na, interferences, fractals, o pinagsamang mga larawan pati na rin lamang ng isang maliit na bahagi ng hindi pangkaraniwang bagay na ito, na maaaring marahil mangyari lamang salamat sa napaka-bihirang mga pakikipag-ugnayan ng ilang coincidences, sa ilalim ng mga kondisyon na hindi pa sapat na ipinaliwanag, maaaring lamang napaka tinatayang tinatantya at kunwa sa laboratoryo o computer.
