It doesn’t get much cooler than this.<\/p>\n
Physicists at MIT have created what may be world’s coldest chemically stable molecules<\/a>, chilling sodium potassium gas to half of one millionth of a degree above\u00a0absolute zero<\/a> (defined as minus 273 degrees Celsius or minus 460 degrees Fahrenheit, or 0 on the Kelvin scale used by many scientists).<\/p>\n “Now we\u2019re at 500 nanokelvins, which is already fantastic, we love it,” Dr. Martin Zwierlein, one of the physicists, said in a written statement. “A factor of 10 colder or so, and the music starts playing.\u201d<\/p>\n Scientists create such “supercold” molecules in order to observe exotic forms of matter and quantum processes<\/a>, according to Live Science.<\/p>\n Among the exotic forms of matter the researchers hope to see are so-called “superfluid crystals.” As Zwierlein explained in the statement, these crystalline forms “feel no friction, which is totally bizarre. This has not been observed so far, but predicted. We might not be far from seeing these effects, so we\u2019re all excited.\u201d<\/p>\n
