cardinal points could have been achieved by a simple means.
"It's impressive, close to perfect. But, as Dash also points out, not
exactly perfect. In fact, the pyramids' alignments all suspiciously err
to exactly the same degree. "All three pyramids exhibit the same manner
of error; they are rotated slightly counterclockwise from the cardinal
points," he added.
And this consistent error, Dash believes, might just provide the clue
that finally solves the mystery of how these alignments were made. In
fact, he and his team have devised a method that can achieve the same
precision and, tellingly, the same degree of error found in the
pyramids using nothing more than a simple rod-and-shadow trick.
The method, using just a rod and a string, relies on the shadows
generated during the autumnal equinox, the moment when the plane of
Earth's equator passes through the center of the sun's disc."
