        Hey Genius-

        Topics of constant debate! The debate is whether these is more antimatter (the opposite of matter) or more matter. It is basically the same as matter, just with opposite spin and charge. This is what the scientists are trying to explain with big colliders like the ones at CERN. There are some results they are detecting that show that processes that prefer the creation of mater of antimatter, which leads to the excess of matter that we see today. Alternative explanations include that the universe is actually made of antimatter, but that antimatter is repelled by gravity.
