Anti matter is what

Scientists believe that anti-matter is composed of elementary particles that have the same mass as their corresponding particles in ordinary matter, but with opposite charge. When a particle of matter comes into contact with its anti-particle counterpart, they annihilate each other, releasing a large amount of energy in the process. Anti-matter is a topic of interest in particle physics and astrophysics as it could potentially provide insights into the early universe and fuel for future space travel.
