We should all be very thankful for the simple act of spinning that our precious Earth goes through every single day and night. But the spinning itself happens at a higher rate than expected, baffling the minds of scientist. 

Phys.org brings us the intriguing news, as scientists noted that last year on July 19, it was recorded a day shorter by 1.4602 milliseconds than the usual ones.

Several explanations for the discovery

Scientists still have a long way to discover what could have produced such an incredible effect on our planet. Plenty of factors can impact planetary spin, such as global warming, snowfall levels, mountain erosion, and the Moon’s pull.

According to Daily Mail, every day since 2020 lasts less than 24 hours. The collecting of data by scientists began in the 1960s, which means that practically, the day of July 19 (2020) was the shortest day ever recorded.

Live Science writes:

The 28 fastest days on record (since 1960) all occurred in 2020, with Earth completing its revolutions around its axis milliseconds quicker than average.

The International Earth Rotation and Reference Systems Service (IERS) is responsible for measuring the length of a day, and the scientists “determine the exact speed of the Earth’s rotation by measuring the precise moments a fixed star passes a certain location in the sky each day. This measurement is expressed as Universal Time (UT1), a type of solar time”.

While our planet’s spinning forms the day and night, things are not the same on other planets from our Solar System. The Moon, for instance, meaning our every night companion, doesn’t follow the same pattern.

Until an irrefutable answer comes, we’re all free to take our best guess for what could have caused the faster spinning of Earth.
