So, semi-simple antimatter physics state that when antimatter comes in contact with regular matter, an explosion occurs. If there is only antimatter and matter in the universe, how can antimatter even exist, since it will come in contact with matter at one point and explode? So how are scientists able to capture it? They store it in a container made out if matter, so why doesn't that explode? This really doesn't make sense to me. Maybe there could be such a thing called neutral matter, whose atoms are solely composed of neutrons?
