June 29, 2022, was the earth’s shortest day since atomic clocks began in the 1960s due to a slight “wobble.”
According to Fox News, Wednesday, June 29, was slightly shorter than any other day by just 1.59 milliseconds, meaning the earth completed one spin in a fraction of a second less than 24 hours.
Scientists say the cause is due to the earth not being a perfect sphere, causing it to wobble slightly. Other causes of the earth’s wobble include ocean tides, gravity from the moon, and climate.
According to Insider, in the last few years, the earth has experienced shorter days, and if the planet continues to speed up, it could lead up to the first-ever requirement to subtract a second from atomic clocks.
