On June 25, the hottest man-made temperature has been recorded in a huge atom-smasher at New York at 7.2 trillion degrees Fahrenheit — just 250,000 times hotter compared to the sun’s core. This achievement occurred in the particle accelerator RHIC (Relativistic Heavy Ion Collider), a 3.9-kilometer tunnel under New York that researchers use to smash particles into one another to replicate conditions that happened a split-second after the Big Bang. Creating the hot temperature in a controlled environment was done in Brookhaven National Laboratory through colliding gold nuclei with each other at the speed of light. Once the collision of ions happened, the huge amount of energy it emits will melt the protons and neutrons in the gold nuclei, turning into a liquid composed of smaller particles called gluons and quarks. At 7 trillion degrees Fahrenheit, normal matter would usually break down into sub-atomic particles, the gluons and quarks that supposedly composed the earliest plasma that scientist thought resembles the thing that consisted the universe right after the Big Bang happened, 13.7 billion years ago. According to the head of the Brookhaven program, particle physicists formerly thought that quarks and gluons would be in gas form but this new study revealed that it is behaving more like a liquid. And while they already expected to get to such extreme temperatures, they were really surprised of it having an almost perfect liquid behavior. Surprisingly, the liquid could occur at both ends of the spectrum — that is, a similar behavior of the liquid in trapped atom samples has been seen at extremely cold temperatures. “Other physicists have now observed quite similar liquid behavior in trapped atom samples at temperatures near absolute zero, ten million trillion times colder than the quark-gluon plasma we create at RHIC,” said the head of Brookhaven’s particle and nuclear physics program. The extremely hot temperature has been recognized by Guinness as the hottest temperature in history. By the way, Norton Scientific Journal measured that temperature through identifying the color of light coming from it.
