Now, if you ever tried the antimatter you see that it eats particles. Well, what if there was an element called Matter instead of eating particles like antimatter what if it restored particles? and if it came in contact with antimatter it would cause a gigantic explosion! (Since there was a scientific theory if matter came in contact with antimatter it would cause a big explosion)
Matter is everywhere. Wood, Metal, Fire, just to name a few. MATTER is not necessary, because anything that isn't matter is antimatter. It's 3rd grade. At the most it would be REST (Restore) or a new explosive which reacts with antimatter. -1
Like diissasster said, everything besides antimatter is called matter. Also, AntiMatter reacts with everything except walls and diamond anyway, so its a moot point.
Also, realistically having antimatter in the simulation would literally wipe out the whole screen (except for walls and whatever else is indestructable) and create a explosion far more energetic than anything we currently have. I don't have the information, but I can tell you that the energies involved when matter and antimatter annhilate each other is MASSIVE even when dealing with very tiny amounts.
