Washington: An international team of scientists recently claimed to have set the world record for creating coldest cubic meter in the Universe.
Scientists working on the cryostat that's part of the Cryogenic Underground Observatory for Rare Events experiment (CUORE) cooled an 880-pound block of copper to a temperature of six milliKelvins, the Huffington Post reported.
Dr. Karsten Heeger, director of Yale's Arthur W. Wright Laboratory, has been involved in the CUORE collaboration, which conducts the cryogenics research. The collaboration, based at the Gran Sasso National Laboratory in Italy, involves 130 scientists from the U.S., Italy, China, Spain, France, and other countries.
The record-setting cold temperature, achieved with a chamber-like device known as a cryostat, would be a prelude to another experiment that might help explain the behavior of ghostly subatomic particles known as neutrinos, and it might answer longstanding questions about the composition of matter in the universe.
Scientists stated that the experiment would look at a rare process called neutrinoless double-beta decay and detection of this process would let researchers demonstrate, for the first time, that neutrinos and antineutrinos are the same, thereby offering a possible explanation for the abundance of matter, rather than anti-matter, in the universe.
