Antimatter (shouldn't be confused with Dark matter) is a negative particles, completely opposite to their normal versions (like numbers 1 and -1). Antimatter is reacting with normal matter strangely. If Normal matter and Antimatter particles will collide, they will annihilate each other, like numbers 1 and -1 after summing).
