"The Higgs boson is a cornerstone of modern physics despite never being seen. It is believed to play a key role in imbuing things with mass. It is the last missing part of the Standard Model, a suite of equations that has held sway as the law of the cosmos for the last 35 years."
In popular culture the Higgs boson is also called the God particle after the title of a book by physicist Leon M Lederman, who claimed that the particle was God-like in that it was "so central to the state of physics today, so crucial to our final understanding of the structure of matter, yet so elusive".
This video quickly and simply explains what a particle accelorator/collider is, what a Higgs bosen is, and gives us a glimpse at why this is all important in order to understand the nature of the universe.
