This delay was found to be less than three attoseconds (one quintillionth of a second long) and is caused by slightly different motions of the lighter and heavier nuclei.&#013;<br \/>\n&#013;<br \/>\n&#013;<br \/>\n Click here for original story, <a href=\"https:\/\/www.sciencedaily.com\/releases\/2022\/12\/221205104236.htm\" target=\"_blank\" rel=\"nofollow noopener\">Measuring times in billionths of a billionth of a second<\/a>&#013;<br \/>\n&#013;<br \/>\n&#013;<br \/>\nSource: ScienceDaily&#013;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Scientists have developed a novel interferometric technique capable of measuring time delays with zeptosecond (a trillionth of a billionth of a second) resolution.
