The world's largest particle accelerator is being built at the CERN laboratory on the border of France and Switzerland. Six stories high, in a tunnel 300 meters below ground, the accelerator is part of a project designed to allow physicists to recreate the first moment of the universe, the first infinitesimal fraction of a second after the Big Bang.

Filmmaker Samy Brunett is a former employee CERN laboratory. For SCIENTISTS AT THE RIM OF REALITY he returns to the lab for an update the quest to understand the universal laws. He finds scientists pushing their machines to the edge of technological feasibility, in search of the 'divine particle,' the Higgs boson, the missing link in the Theory of Everything.

Over the past two decades science has changed dramatically. Scientists have been expanding the limits of their investigative methods by implementing new concepts such as symmetry and uncertainty. Thanks to today's technology, they are formulating theories that may provide insight into the most profound questions of our age.
