At the very beginning of our universe, a short phase after the big bang, everything is supposed to have existed in the form of a hot soup of particles, presumably containing equal proportions of matter and anti-matter. As the universe expanded in size, the overall temperature lowered and particles coalesced together to form the various structures that we detect with our modern-day astronomical instruments and technology. 

Anti-matter, which is basically the opposite of matter, in most respects behaves just like its matter counterpart, the only key difference is in the charge that it carries. For example, the anti-particle of the electron, a negatively charged particle, is called the positron, which as the name suggests is positively charged. An interaction between electron and positron causes annihilation leaving just photonic radiation behind....
