Earth Breaks the Record , for the Shortest Recorded Day.<br />The International Earth Rotation and Reference Systems Service reported the record-breaking time on Aug. 8.<br />According to the calculations of scientists with the service, .<br />... the Earth's rotation on June 29 was 1.59 milliseconds shy of its standard 24-hour rotation.<br />This time is the shortest time recorded since the atomic clock was invented to keep an accurate-as-possible record of the rotation of the Earth.<br />The last time the Earth broke a <br />rotation-time record was on July 19, 2020.<br />On that day, our planet was 1.47 milliseconds under the standard 24-hour rotation.<br />While scientists have theorized that the rotation of the Earth has slowed since the time of the dinosaurs.<br />... there is evidence to suggest that the speed of its rotation is beginning to speed back up.<br />However, scientists also say that the increased speed is too minute for humans to notice. .<br />Our day-to-day existence doesn't even recognize that millisecond, Dennis McCarthy, U.S. Naval Observatory, via KSL.com.<br />However, scientists also <br />say that the speed is significant <br />enough to make a difference.<br />If records continue <br />to show an increase <br />in the speed of the <br />Earth's rotation, .<br />... a "leap second" will likely need to be considered sooner than scientists had anticipated.<br />But if these things add up, then it could change the rate at which we insert a leap second, Dennis McCarthy, U.S. Naval Observatory, via KSL.com
