"1. Higgs boson / God particle
The Higgs boson, proposed by Peter Higgs in 1964, if it exists, is what gives matter mass. It has also been named the name God particle by American physicist Leon Lederman. "He wanted to refer to it as that 'goddamn particle' and his editor wouldn't let him," Higgs told the Guardian. So "God particle" it was.
