Betz Sphere
Polished metallic sphere recovered from a forest fire site in Florida that exhibited apparently anomalous behaviour, self-stopping motion, low-frequency vibration, and resistance to standard analysis. Examined by the U.S. Navy and the Omega Research Lab.
Overview
On March 26, 1974, the Betz family discovered a small, polished metallic sphere amid the ashes of a brush fire near their property on Fort George Island, Florida. Approximately 20 cm in diameter and weighing 9.5 kg, the sphere appeared featureless except for a small triangular symbol. Witnesses reported that the object would roll back to its original position when displaced, produced low-frequency vibrations that affected nearby animals, and resisted denting or scratching. The U.S. Navy at Jacksonville Naval Station examined the sphere, identifying it as machined stainless steel, but private testing at the Omega Research Lab and by Dr. Carl Willson (who measured persistent magnetic field changes) produced more anomalous readings. The case was widely covered in U.S. press in 1974 and again revisited by researchers in 1996 and 2017.
