The + trending A study reveals that in 2020 the record was already broken and in this it will be even shorter
Lhe coronavirus pandemic was not the only strange thing that happened during 2020, since our planet Earth has been spinning faster than usual for the last few years, with 2020 being the worst of these, since of the 366 days, These were the shortest for humanity since 1960.
The thing to keep in mind is that the Earth works like a stopwatch, turning completely once every 86,400 seconds, that is, every 24 hours, but these rotations are not perfect, since sometimes they tend for less or more than seconds before set.
Thanks to the studies carried out by timeanddate.com, it has been possible to corroborate that during 2020, the record was broken at least 28 times as the shortest days, with July 19 being the first place. That is why according to science, it is calculated that by 2021, every day will be shorter than its 86,400 seconds, with an average of 0.05 milliseconds. The fact that every day of the year is on average shorter than 24 hours has not happened since 1937.
According to the Earth Orientation Center, this event has its pros and cons, that is, it can be useful for the actual synchronization of astronomical observations according to the time indicated by certain atomic clocks. While its negative part includes the collection of data for some infrastructure or telecommunications applications.
The end result of the entire duration of a day is derived from a process in which scientists determine the speed with which the Earth completes its rotation on its same axis, taking as references, natural or artificial satellites for a greater precision of the time that was required to get to that point. This entire process is known as Universal Time (UT1) and just after collecting the aforementioned information, a comparison is made with International Atomic Time, which is a very high precision time scale with more than 200 clocks. established in laboratories in different parts of the world.
