    The coldest chemical reaction makes the molecular formation time "exposed" for the first time American scientists published a paper in the latest issue of science magazine, saying that at a temperature millions of times colder than the interstellar space, they caused the coldest chemical reaction between two supercooled molecules in the universe so far, forming the coldest bond in the history of molecular coupling They say scientists can use this supercooled chemistry to understand exactly what happened during a chemical reaction According to Ni kangkun of Harvard University, under 500 nakkelvin (only a few millionths of a degree Celsius higher than absolute zero), the movement speed of molecules dropped to a very low level, and they saw a scene that no one had ever seen before: the moment when two molecules meet to form two new molecules Http://digitalpaper.stdaily.com/http_www.kjrb.com/kjrb/html/2019-12 / 04 / content_ HTM?
