What state of matter, achieved briefly in particle accelerators like the LHC, reaches temperatures in the trillions of Kelvin?
Answer
Quark-gluon plasma
The highest temperatures engineered by humans, far surpassing even the calculated cores of stable stars, are achieved in particle accelerators such as the Large Hadron Collider (LHC) at CERN. When heavy ions are accelerated to near the speed of light and subsequently smashed together, they momentarily create a state of matter known as quark-gluon plasma. The thermal extreme reached in this fleeting event is measured in the trillions of Kelvin, representing the most intense thermal environment currently created artificially.
