Oxygen collisions at the LHC show new indications of extreme state of matter

Phys.org reports that researchers at the Large Hadron Collider have observed oxygen-oxygen collisions. This experiment provides new data regarding conditions found in the early universe. By smashing oxygen ions together, scientists recreate extreme heat and density levels that existed milliseconds after the Big Bang.

The findings point toward significant differences in how matter behaves under these intense pressures. This data helps physicists refine their models of quark-gluon plasma, a state of matter that fills the void of the early cosmos. Scientists use these collisions to map out the properties of subatomic particles with higher precision than previous proton-based tests allowed.

This work continues to push the boundaries of particle physics at the CERN facility. The oxygen ion run is a shift from traditional lead or proton collisions, offering a unique look at how medium-sized nuclei interact. Experts suggest these results offer a clearer window into the state of the universe during its formation stages.
