Well, if there is matter, then there has to be a form of matter that is the opposite of it, named anti-matter by scientists. There is the + and - sign, there is the North and South Pole, there is the add and subtract, multiply adn divide, so there must be a kind of matter that reacts quite the opposite of matter, something that cancels out matter. That is why scientists theoritically say that when matter and anitmatter clash, a hugh explosion is the result of the combination of the two opposite materials. Of course, if there has to be more of matter than anti matter if there still is matter right now, or else antimatter would have canceled out our entire world! It is still a mystery on how to make antimatter, but then again, we aren`t sure on how to make matter as well. Matter is like energy, you can`t create it or destroy it, you can only modify it. Does this answer your question?
