![]() ![]() But if one of the main ways matter and antimatter are opposites is charge, then what does it mean that neutrinos are neutral? Does that mean neutrinos and antineutrinos are the same thing, only differing in the particles (positrons or electrons) produced along with them? Scientists aren’t sure. When matter and antimatter meet, they annihilate in a fiery burst of light.Īn antineutrino is thus simply an “opposite version” of a neutrino. It is also possible to create antiatoms in a laboratory and study them, though this is very difficult to do. ![]() ![]() Scientists aren’t sure where all of the antimatter is, but hope experiments like the Deep Underground Neutrino Experiment will shed light on this issue in the near future. Antimatter particles such as antiprotons and positrons can get together to form antiatoms the same way protons and electrons form atoms. However, most of what we see in the universe is made of matter rather than antimatter. An antiproton is a negatively charged proton.
