Over four fifths of the matter in the universe is an unseen, unidentified substance known as dark matter. Astronomers posited the existence of dark matter in the 20th century but discovering its true nature had become a key goal for experimental physicists in the 21 Century. Scientists are now closing in on the elusive stuff with major experiments underway on three fronts — in space, in deep underground laboratories and in the heart of the world’s largest particle accelerator. The coming 18 month are expected to be crucial because it is a period during which dark matter with either be found or a wide range of possible explanations for it will be ruled out.
