Only 17 anomalous events have occurred since the beginning of the project, all of which were probably neutrons.
A device used to detect them on Earth is made of silicon and germanium crystals and as the incoming particles strike the crystals, a temperature change and the change in electron-hole pairs is recorded, and a comparison of the signals allows scientists to rule out cosmic rays, neutrinos, and other radiation. Only 17 anomalous events have occurred since the beginning of the project, all of which were probably neutrons. If they do exist, there is approximately one in each 150 cubic centimeters of space, and they do not respond to the electromagnetic or strong forces. FTP, identify these particles which obey gravity and the weak force and may make up a portion of the universe's dark matter.
