Antimatter

A type of matter whose electrical charge properties are the opposite of 'normal' matter. For example a 'normal' proton has a positive charge, but an antiproton has a negative charge. It can be used in a number of ways, such as weaponry, fuel, scanning technology, and medical uses.

Antimatter can be used to interact with, modify, or destroy normal matter. When a particle of antimatter is brought into contact with an equivalent particle of normal matter, both particles are annihilated, and a considerable amount of energy is released. The controlled annihilation of matter and antimatter is used as the power source for the warp drive systems used aboard Federation starships.
