In the collective modern imagination, crop circles are usually attributed to either aliens or a vast human conspiracy; possibly both. Some circle-watchers believe the designs are landing strips, maybe, or some kind of communiqué from outer space. Others argue they’re the result of secret government tests, or perhaps secret codes meant to convey information to satellites and aerial drones.
For all the talk about who makes them, few people discuss how. Do people (or little green men) stomp around willy-nilly until the stalks fall down? Or is something decidedly more high-tech going on? We talked to a circlemaker and a materials physicist to get some answers.
It’s a fair scientific question, according to Richard Taylor, a professor of physics and art at the University of Oregon. He believes circlemakers, as they’re known, are using some advanced technology, from microwaves to GPS, to make their increasingly complicated designs.
