Foucault’s Pendulums Do Not Prove the Earth Is Spinning

“Foucault’s Pendulums are often quoted as proof of a rotating Earth but upon closer investigation prove the opposite. To begin with, Foucault’s pendulums do not uniformly swing in any one direction. Sometimes they rotate clockwise and sometimes counter-clockwise, sometimes they fail to rotate and sometimes they rotate far too much. The behavior of the pendulum actually depends on 1) the initial force beginning its swing and, 2) the ball-and-socket joint used which most-readily facilitates circular motion over any other. The supposed rotation of the Earth is completely inconsequential and irrelevant to the pendulum’s swing. If the alleged constant rotation of the Earth affected pendulums in any way, then there should be no need to manually start pendulums in motion. If the Earth’s diurnal rotation caused the 360 degree uniform diurnal rotation of pendulums, then there should not exist a stationary pendulum anywhere on Earth!”(1)

The pendulum’s movements clearly do not substantiate a spinning globe. What these movements likely do, however, is substantiate the fact that there are electromagnetic forces surrounding the Earth that cause the particular circular movements of the pendulum. There are documented cases of erratic changes in the pendulum’s movement during solar eclipses, indicating that a spinning Earth had no involvement in the pendulum’s change.

It’s also important to keep in mind that these devices are not perpetual motion machines and therefore require an electrically operated magnetic source to continue swinging or they will eventually come to a stop. (see link to manual below)
