As we know, the Earth revolves around itself every 24 hours. But most of us probably don’t know that the length of a day varies depending on different factors. Tidal forces between the Earth and the Moon sometimes cause the day to lengthen. Approximately every 100 years, the Earth’s orbit is lengthened by a few milliseconds.
For this reason, in some years, 1 second is added to the hours and this is called a leap second.
But now Earth is surprisingly experiencing the opposite. The record for the shortest day has been broken several times since 2020. It’s been 28 times, the shortest day since the 1960s. Finally, on June 29, 1.59 milliseconds was measured, which shortens each 24-hour rotation. Thus, June 29 was recorded as the shortest day on Earth.
No one knows why this shortening occurred. One theory is that the axis of rotation is touching.
Software giants such as Facebook, Google, Amazon and Microsoft are already completely against the idea of leap seconds. Because adding an additional second to the day creates the possibility of affecting software. Now, the concept of “missing seconds” may come into play. But at least there is no such expectation for 2022.
