Relativistic Heavy Ion Collider (RHIC) is located at Brookhaven National Laboratory in New York. It is 2.5 mile ring designed to slam gold nuclei near the speed of light. It simulates the Big Bang in small scale. The energy produced by the collision ripped the proton and neutron apart. Inside RHIC scientists found the building block of universe named Quark. They are too small to track. If we can found the behavior of Quark, we can unlock some of the secrets of our mysterious universe.
The project starts at 2000 and it took 5 years to analyze the data. In 2005 they got the shocking result. The universe was not gaseous at that moment. It was in liquid state like a soup. Our early universe turned into a dense hot soup of Quarks.
