Quark Gluon Plasma
On an August day in the year 2012, the LHC (Large Hadron Collider) smashed two atom nuclei together, and this stuff popped out under trillion-degree temperatures.
However, this is not the only time scientests have created these gluons. In the past few years, two particle accelerators, the LHC and the Relativistic Heavy Ion Collider, or the RHIC, have created these fascinating specimens.
What is it?
What even is quark gluon plasma? Well, under the extreme heat, these gluons "melt", and allow the protons and neutrons to each split into their basic components; 3 quarks each.
Scientests theorize that this could have been what the universe was like just milliseconds after the big bang, with the quarks not stuck together by the "glue" of the tiny world. After a few milliseconds passed, the quarks and gluons stuck together and formed protons and neutrons, and ultimately, us.
