Earth's Shortest Day in History: Scientists Link Speedup to the Moon
Earth's rotation has been speeding up this summer due to the moon's position, causing days to be slightly shorter, with upcoming days on July 22 and August 5 expected to be the shortest of the year by a few milliseconds. This change is linked to the moon's gravitational influence, and while the milliseconds are imperceptible to most, they are crucial for precise systems like GPS and computers. Historically, Earth's days have been lengthening over billions of years, but recent observations show a temporary acceleration in rotation.
