If you want to know how the universe works, part of the answer lies in understanding the building blocks of matter—before they became inextricably bound within the protons, neutrons, and atoms that make up everything visible in our universe today. That’s why producers for the Science Channel’s documentary series “How the Universe Works” made a point of stopping by the Relativistic Heavy Ion Collider (RHIC) at Brookhaven National Laboratory, where physicists recreate post-Big Bang “primal matter” millions of times each day. Learn about RHIC’s role in exploring the building blocks of matter by watching this segment. Courtesy of the Science Channel. Twitter: @ScienceChannel Facebook: facebook.com/sciencechannel
