Boring name, but interesting particle - the Higgs boson. Dubbed the "God particle", this has been theorised to be the root of all matter, and the reason why matter particles such as those we're made of condense from energy at all. Researchers have been trying to prove these theories for more than a decade now, and they might just have spotted the elusive Boson at frightening energies.
Is the end of theoretical physics now in sight? If this is the Higgs, it may open up the mystery of the universe itself.
