Why does our universe exist? If there was just as much antimatter as matter in our universe, it would annihilate without ever getting the chance to form stars, stars galaxies and our own planet Earth. You and everything you touch is made of matter. However, if you were to meet someone made of antimatter and shake their hand, the both of you would annihilate in a blinding flash of light...
