The religion of Crop Circle

The SDI Circle Hypothesis:

All cells contain DNA and RNA among other things. These two complex
molecules are especially sensitive to UV frequencies in the range of
260 NM.

In addition, cells can be "denatured" or "melted" when exposed to
temperatures in the range of 73 to 77 degrees Celsius. This causes
the ladder-like structure of the DNA/RNA to begin to separate.

This is one of the reasons high energy sources are so dangerous to
living systems. The energy causes micro-heating in the DNA/RNA
which partially "melts" the tissues.

When the heating is removed (and depending on the degree of
melting), the DNA/RNA will revert to the original mirror symmetry
pattern.

This is not always a perfect reversion to the original pattern
however. Sometimes the patterns are so distorted as to produce
mutations in the form of cancer and other diseases.

Plants also are made up of cells. If these cells are subjected to a
high intensity UV laser, heating occurs causing the plants to melt
like plastic at their weakest point, i.e. the stalk.

Two dimensional laser displays rely on a device known as an acousto-
optic modulator. This is simply a front surface mirror (reflecting
only from the exposed side) which vibrates on either an X or a Y
axis.

When the modulator is driven by a sufficiently fast device (like a
computer), the laser beam can be reflected off the mirror to paint a
picture on any surface. The flatter the surface (and the more
perpendicular to the beam), the more perfect the reproduction of the
intended image.

If a UV laser were to be properly directed from a space satellite
(intended to be used for SDI purposes), it could quite easily
"paint" a picture on earth or crops.
