To study questions of why the universe has matter, physicists can try to create another ?Big Bang' somewhere and study how it evolves. If they only do it once, however, like flipping a coin, there is bias. So they must run a few thousand ?Big Bangs' and wait 14 billion years for each one and see how things come out. Or, they can turn to the new Fundamental Neutron Physics Beam Line at Oak Ridge National Laboratory's Spallation Neutron Source and run experiments at phenomenal power and speed and over several years to get answers to such fundamental physics questions, posed by the origins of matter.
