"Professor Geoffrey Taylor, from the University of Melbourne and part of the scientific team involved with the Large Hadron Collider's Atlas Detector, describes the work as an amazing achievement.
"This state of matter doesn't exist anywhere naturally on Earth and is thought to only now occur during the collision of two neutron stars," he said.
"This will help our understanding of the dynamics of the astrophysical processes taking place as a star collapses.
"Looking at how particle jets and subatomic particles like W and Z bosons are created in heavy lead ion collisions compared to lighter hydrogen proton collisions gives us an insight into the conditions that existed in a quark gluon plasma when the universe was just milliseconds old."
Professor Taylor says the results were accomplished in just two weeks of atom smashing.
"These collisions are also generating antimatter, which will help us try to understand why we live in a stable universe of matter when equal amounts of matter and antimatter were created in the big bang," he said.
"It takes our understanding of things that are happening in the cosmos one step further."
