The Brief July 9 is expected to be one of the shortest days in history, but you won’t notice a difference. The Earth has been moving faster in recent years, and scientists aren’t exactly sure why.

Scientists anticipate that Earth's rotation will quicken enough to create three shorter days between July and August, starting Wednesday, July 9.

“Atomic clocks and our computer networks are the new, far superior form of time measurement, but we’re forcing them to keep in sync with this older form of measurement,” remarks Dr. David ...
