How will antimatter spacecraft work? Well, to answer that you should know the meaning of antimatter. Antimatter is the opposite of the normal matter. Based on the research, scientists have found that anti-particles exist in our universe. These particles are the mirror images of normal matter. Here are some of the particles such as positrons, anti-protons, and anti-atoms.

When those particles come in contact with the normal matter, they collide and produce an explosion at the speed of light. It transfers the entire mass of both objects into energy that is so powerful. This energy is used to generate the engine that can move so fast.
