Four trillion degrees: U.S. lab hits record temp.
From CBS News:
(CBS News) Brookhaven National Laboratory calls it "the world's hottest Guinness." But they're not talking about beer, they're talking about the Guinness World Records organization which recently acknowledged Brookhaven for creating the highest man-made temperature ever. The New York-based laboratory's Relativistic Heavy Ion Collider (RHIC) smashed particles together and created a substance recorded at four trillion degrees Celsius - over 720,000 times hotter than the surface of the sun.
Scientists were not actually going for a record when analyzing results from their particle collider. The RHIC was designed to recreate the conditions in the first few milliseconds after the Big Bang by smashing atomic particles together along the RHIC's 2.4-mile underground "racetrack." The fact that they smashed a record as well is just a bonus.
A Brookhaven press release describes the experiment that led to the incredible record:
When RHIC collides gold ions at nearly the speed of light, the impact energy becomes so intense that the neutrons and protons inside the gold nuclei "melt," releasing fundamental quarks and gluons that then form a nearly friction-free primordial plasma that only existed in Nature about a millionth of one second after the Big Bang. RHIC discovered this primordial, liquid-like quark-gluon plasma and measured its temperature at around 4 trillion degrees Celsius - that's 250,000 times hotter than the center of the sun.
For the record, 4 trillion Celsius is roughly 39 trillion Fahrenheit.

3. CBS News fixed their bonehead mistake.
The line: For the record, 4 trillion Celsius is roughly 39 trillion Fahrenheit is from the original article. Actually, 4 trillion degrees celsius is 7,200,000,000,032 fahrenheit.
They must have originally done the computation by multiplying 4 trillion by 1.8 and then adding 32 trillion rather than 32.
