Betz Sphere Remains A Scientific Mystery Decades After It Was Discovered

The so-called evidence of extraterrestrial has been here for many decades. One of them happened to be the Betz sphere that was found in 1974. Experts conducted several tests of the sphere, and they concluded it as a magnetic object sensitive to magnetic fields, mechanical stimulation, and many sound emissions. They found out that it could stand a pressure of 120,000 pounds per square inch, making them conclude that the thing was composed of stainless steel, particularly magnetic ferrous alloy #431.
