Despite its vanishingly tiny mass, the existence of the axion, once proven, may point to new physics beyond the Standard Model. Theorized to explain a fundamental symmetry problem in the strong nuclear force associated with the matter-antimatter imbalance in our universe, this hypothetical particle also makes an attractive dark matter candidate. Though axions would exist in vast enough numbers to be able to account for the "missing" mass from the universe, the search for this dark matter has been quite challenging so far.
