An antimatter bomb is a theoretical weapon that uses antimatter to produce an explosive reaction. Antimatter consists of particles that have the opposite charge of regular matter; for example, positrons are the antimatter counterparts of electrons. When antimatter comes into contact with matter, they annihilate each other, releasing a tremendous amount of energy according to Einstein's equation, E=mc². Currently, producing and storing sufficient antimatter is extremely challenging and expensive, making the practical use of an antimatter bomb unfeasible. Research in this area is primarily conducted in high-energy physics laboratories, such as those at CERN and Fermilab, where scientists study the properties of antimatter.
