So, anti-matter is real, but it’s not scary. Everything around you is made of matter particles such as protons, neutrons, and electrons. Anti-matter is very similar to regular matter, but it has the opposite electric charge: electrons have a negative charge, but an antimatter electron (called a positron) has a positive charge. There are also some other tiny differences, but they are beside the point. If a matter particle and its antimatter counterpart collide, they will annihilate each other and release energy, but this is not something to worry about, as there is a lack of antimatter in the universe - one of the big mysteries in physics.
