    4. Less than 0.16 grams of antimatter are produced every year
    5. Unequal distribution of matter and antimatter in our known universe is one of the greatest unsolved problems in physics
    6. Practically applied to medical imaging in the positron emission tomography technique

    “On the big Bang theory: For every one billion particles of antimatter there were one billion and one particles of matter. And when the mutual annihilation was complete, one billionth remained - and that's our present universe.” - Albert Einstein
