This is June 29th. Then our planet made one complete rotation around its axis 1.59 milliseconds faster than it did before, writes ScienceAlert.

In recent decades, the Earth has slowed down a bit, causing the days to be longer. Scientists measure this time difference in milliseconds, so you won’t be able to feel it in everyday life.

Now the trend is changing somewhat: the days are not getting longer, but shorter. This means that the Earth is spinning faster and faster. Scientists could not give an unambiguous answer about the reasons for this behavior of the planet.

If the planet continues to accelerate, this could lead to the first ever subtraction of a second from an atomic clock.

What is an atomic clock
This is the name of a device for measuring time, in which oscillations associated with processes occurring at the level of atoms or molecules play an important role. Without atomic clocks, modern navigation would be impossible.

In particular, determining the position of spacecraft, satellites, ballistic missiles, aircraft, submarines, as well as the movement of vehicles in automatic mode via satellite communications (GPS, GLONASS, Galileo) are carried out using atomic clock readings.
