The atomic clock accurately records the length of each day in milliseconds. Since the adoption of the new technology in the 1970s, the length of a day and night is slightly longer than 24 hours. However, starting from the middle of 2020, the rotation of the earth has accelerated.

Earth Trivia: The Earth will rotate at a rate that exceeds the past 50 years

According to official data, time is passing faster now than at any time in the past half century. According to a report by the “Daily Mail”, if it took 86,400 seconds for the earth to rotate once, then this number is now smaller.

Until 2020, the shortest day occurred in 2005, but this record has been broken 28 times in the past 12 months. On July 19, 2020, this day was 1.4602 milliseconds shorter than the full 24 hours. Note that this is the shortest day on record.

On average, a day will be 0.5 milliseconds less than 24 hours. This tiny loss of time, found only at the atomic level, has a profound impact. Time measurement personnel around the world are discussing whether one second should be deleted in time to adapt to this change, which will make the time measurement accurate and consistent with the rotation of the earth.

Since the 1970s, a total of 27 “leap seconds” have been added to make atomic time consistent with solar time. This is because satellites and communications equipment depend on the time that is exactly the same as solar time, which depends on the positions of the stars, moon, and sun.

In order to maintain the harmony of this relationship, the timekeepers of the International Earth Rotation and Reference System serving the Earth Orientation Center in Paris, France used to add so-called “leap seconds” on a certain day. The last time a leap second was added occurred on the last day of 2016.

Fossil energy sources such as coal and oil have all turned into gas and a small amount of solid residue, so that the earth becomes lighter?
