The European Laboratory for Particle Physics (CERN) announced that performed collisions of lead ions at a record energy in order to advance the study of what was the state of matter just after the “Big Bang “, when considered in the formation of the universe.
The energy recorded was almost two times higher than any previous experiment, reaching temperatures of billions of degrees (hundreds of thousands of times the Interior Sun), a week after starting the first collisions.
This marks the start of a month of lead collisions of charged ions (lead atoms without electrons).
The collision of ions is a “tradition” that CERN fulfills one month a year, but this time “will be special, because we reached a new energy and explore the material in a period even earlier in our universe,” he said in a statement the CEO of the organization, Rolf Heuer.
In the early universe, a few millionths of a second, the matter was a very hot and dense medium, a “primordial soup” composed elementary particles, known as “quarks” and “gluons”.
The latter keep the quarks together inside protons and neutrons that make up matter.
During the first period operating the Large Hadron Collider (LHC), between 2010 and 2013, there were significant advances in the understanding of the properties of plasma of quarks and gluons.
