    Antimatter is not just matter with an opposite charge. It's matter with every type of charges (electromagnetic, strong and weak nuclear charges) inverted, as well as the "parity", that is the relative direction of its spin compared to its propagation direction, are all inverted.

    If you look for "CPT symmetry", you'll find better explanations than this.

    It basically boils down to this: invert the flow of time, and every particle will look like antimatter, while antimatter will look like normal matter.

    It would have been very likely that antimatter moved backwards in gravity of it was normal matter moving backwards in time!

        There's also no real reason for there to be more matter than antimatter in the universe. Any sufficiently high energy action will produce equal amounts of matter and antimatter, but there's overwhelmingly more matter than antimatter floating around. It's one of the big questions.

      You just wrinkled my brain.
