Are crop circles man-made or a genuine mystery. Here's some of the best evidence for a paranormal phenomenon.
EFFECTS ON EQUIPMENT
Researchers claim that their electronic equipment is often affected when they are examining crop circles. "There have been numerous reports of electronic equipment failing in crop circles and compasses spinning out of control in and over the crop circles (when flying over in aircraft)," according to "Peculiarities of Crop Circles". "This range of equipment includes watches, mobile phones, batteries, cameras. No explanations for these occurrences, other than the indication of a strong EM field distortions."
EM MEASUREMENTS
Longtime crop circle investigator Colin Andrews says he has recorded electromagnetic (EM) measurements of 40-50 nano Teslas at the centers of some formations, which he says is 10 times the radiation level of a normal field.
STRANGE SOUNDS
Researchers say they have sometimes detected an unexplained sound at 5KHz frequency emanating from crop circles for just a few days after they are formed. "This corresponds to reports of eyewitnesses who often claim to hear a 'trilling' sound coming from the direction of the formations," says "Peculiarities of Crop Circles".
RADIOACTIVE ISOTOPES
In 1991, two American nuclear physicists, Michael Chorost and Marshall Dudley, applied their expertise to crop circle research. "After subjecting a number of seed and soil samples to rigorous lab analysis," according to Freddy Silva's article, "Analysis of Crop-Circle Affected Crops and Soil," "their main discovery was that the soil in genuine formations contained no less than four, short-lived radioactive isotopes - vanadium, europium, tellurium and ytterbium. Tests conducted on soil from the Beckhampton July 31 formation yielded alpha emissions 198% above control samples, beta emissions 48% above, both of which seemed 'strikingly elevated,' since they were two to three times as radioactive as soil from outside the formation." Analyzed DNA samples from plants in another circle were found to be considerably more degraded than that of surrounding plants.
