The Deep Dive series takes a closer look at the strongest crop formations and the questions around them. Each video covers one theme, from the hydrogen signature to the cover-up debate. All the videos are also on the videos page. Challenging the narrative

Many crop formations carry real mathematics. Some encode numbers. Some draw fractals that need a computer to plot. These are the clearest examples in the Crop Signals catalogue. Fractals A fractal is a shape that repeats itself at every scale. Several of the highest rated signals are fractals. Numbers and constants Sound Cymatics is the […]

Contact Through Crops sets out the evidence that some crop circles come from a higher intelligence. This is a summary of its main points. Early history Reports of patterns in crops go back centuries. The best known is the Mowing Devil pamphlet of 1678, which blamed a circle in a field of oats on the […]

If some crop circles are made by a higher intelligence, how are they made? A handful of formations seem to answer that question themselves. They look like diagrams of a device and the process it uses. This post walks through them in order. 2000. The signal device diagram On 10 July 2000 a formation appeared […]

If crop circles are a real phenomenon, why are there so few records of them before the 1970s? Folklore mentions them, but written accounts are scarce. Here are some possible reasons. Lost and destroyed records For much of the medieval period, writing that touched on the supernatural could be treated as heresy. Books were burned […]

Sceptics often point to construction lines and mistakes in formations as proof that people made them. The argument is that a higher intelligence would need no guide lines and would make no errors. It is a fair point. It also rests on assumptions worth testing. Construction lines The claim. Guide lines show that people made […]

The Crop Signals book, Contact Through Crops, is out now. It asks whether crop circles are art, hoaxes or messages from a higher intelligence. It looks closely at the strongest formations, including the hydrogen signature, the Arecibo response, the DNA disc and the device series. The book argues that there are two kinds of formation. […]

Many of the formations rated as genuine signals appear close to the white chalk horses of southern England. This post looks at that link and the theories behind it. The white horses There are around 16 white horses cut into the chalk hills of Britain. Most are in Wiltshire, with others in Oxfordshire and nearby […]

Photo by Ben Sasson There are two main explanations for crop circles. One says they are messages from a higher intelligence. The other says people make them, as art or as pranks. This post sets out the case for each and where the Crop Signals Project stands. The case for a higher intelligence The weakness […]

Many people accept that every crop circle is made by people. Some certainly are. Here are five reasons to doubt that all of them are. 1. Strange events in and around the formations Light orbs, odd fogs and patterns that return faintly in the same field the following year. Crops are bent at the growth […]

Crop circles, also known as agrograms, have puzzled people for decades. Sceptics say they are pranks. Those who take them seriously have several theories. Here they are, from most likely to least likely in our view. 1. Messages from beings elsewhere The designs are deliberate messages from an advanced civilisation. Their complexity and precision point […]

AI image tools can now turn simple shapes into detailed pictures and video. As an experiment we fed them crop circle patterns to see what they would make. Some results are below. We think AI could become a useful tool for spotting meaning in the patterns.
