How would you watch a procedure that takes more than one trillion times longer than the age of the universe? The XENON Collaboration investigate group did it with an instrument worked to locate the most subtle molecule known to mankind – dark matter. In a paper to be distributed in the diary Nature, scientists declare that they have watched the radioactive rot of xenon-124, which has a half-existence of 1.8 X 1022 years.

“We really witnessed this decay. It’s the longest, slowest process that has ever been legitimately watched, and our dark matter finder was sufficiently delicate to gauge it,” said Ethan Brown, a professor of physics at Rensselaer, and co-creator of the examination. “It’s an astonishing to have seen this procedure, and it says that our identifier can gauge the rarest thing at any point recorded.”
