The Big Bang theory predicts that when the universe was born in a great amount of energy, matter and antimatter were created. This is the reverse of when we see large amounts of energy resulting from the eradication of an equal amount of matter and antimatter. So, we are left to wonder where is the antimatter companions to the matter that makes up all we know? Could it be in some distant galaxy and we just don't realize it? This possibility is being explored by keeping an eye on the sky. If an area existed where there was a great deal of antimatter, there would likely be a fringe where matter would collide with the system. So scientists are looking for parts of the galaxy that emit gamma rays, which would indicate the presence of antimatter meeting matter. There has been no significant find of gamma rays that would hint at an anti-galaxy. However, recently scientists have discovered huge amounts of antimatter shooting out of the center of our galaxy.  What is the reason for this fountain of antimatter?  Only time and diligent research will tell.

To understand the theory, we have to picture the creation of matter. A high energy event causes matter and antimatter to form. But as the two are formed, most of it simply collides with its opposite and becomes negated again. What if just once per billion time this happens, not all of the matter is destroyed? That small chance would be enough to form all the matter of the universe. In 1966 Russian physicist Andrei Sacharov outlined three conditions necessary for a matter-antimatter imbalance to be possible. The first says that protons must decay, but so slowly that for all the protons in the Earth, fewer than a bread crumb's worth should have decayed so far. The second constrains the way the Universe must have cooled after the Big Bang, and the third describes a measurable difference between matter and antimatter. Experiments have been trying to measure this difference ever since. The third condition has finally been met with the latest research at Fermilab that has proven there is a differance between matter and antimatter. We can now theorize that this is the way the matter was created.
