love to read your articles. If anti matter and matter are in the same amount then if we add them together the universe will become empty, right?

In theory there should be equal amounts of matter and antimatter, so any particles that did form would not last long before annihilating. The universe wouldn't exactly be empty, but instead would be full of particles popping into existence before disappearing again a few minutes later. Things like planets, stars and galaxies would be impossible.
