Physicists claim world coldest temperature achieved
Colorado researchers led by Carl Wieman report reaching 459.67 degrees Fahrenheit, 1.1 millionth of a degree Celsius from absolute zero, using cesium atoms confined by diode lasers. The team notes the result advances basic matter knowledge and could boost atomic clock precision by a factor of 100, with broader practical potential.
