Antimatter is everything matter is not: the protons are negative, the electrons are positive, and the neutrons are neutral. Physically, there is not much difference between matter and antimatter, the seem to follow the same basic principles as matter. But, although they act alike, when in the presence of one another, they annihalate each other and release an amazing amount of energy.
This antimatter energy is not hard to come by. Simply create antimatter in an accelerator, present it to matter, and it creates useable energy. Engineers everywhere are searching for new, efficient ways to get to planet Mars. People have tried combustion, people have tried nuclear. Why not antimatter? The energy is so easy to create, and it is almost impossible to run out of fuel because matter is everywhere! Noone has yet to attempt or even theorize the use of antimatter thrusters, but prove me if I'm wrong.
