Super Kamiokande Neutrino Detector, Japan. Every second 65 billion neutrinos pass through every square centimeter of our body and the Earth. They do not carry electric charge, so that they are not affected by electromagnetic forces acting on charged particles such as electrons and protons. They are extremely tiny traveling mostly undisturbed through matter. This makes neutrinos very hard to detect. The harder a particle is to detect, the more massive and sophisticated the detectors have to be.
