13:03 Gerald S. Hawkins, a retired astronomer, believed that his analysis of crop circles revealed a new kind of Euclidean geometry, suggesting that they were created by something beyond human understanding, but his findings have been challenged and not recognized in academic math forums.
17:26 Crop circles are often localized to specific areas, such as where Dave and Doug lived, and some theories suggest that they are created as a form of subversive art and prank.
21:47 Crop circles have been theorized to be created by down drafts from helicopters and airplanes, swirling ring winds called vortices, humans, dust particles caught in charged air, electromagnetic radiation, and even microwave energy.
26:03 One theory suggests that crop circles can be created using a magnetron and microwaves, causing the crops to expand and fall over, similar to popcorn.
30:24 Crop circles can be created using a magnetron and microwaves, or by using ropes and planks to stomp down the crops in a specific design.
34:33 Crop circles are often analyzed using various methods, but skeptics have debunked them based on factors such as an increase in frequency, concentration in certain regions, and the lack of evidence of them being formed.
