The Earth recorded its shortest day on July 29th as the day was 1.59 milliseconds shorter than 24 hours. The data revealed by the International Earth Rotation and Reference Systems Service highlights that it is the shortest day ever since scientists started using atomic clocks to measure the motion of the Earth.
Scientists say that the duration of the day is the time it takes for the Earth to rotate once on its axis. This process typically takes 86,400 seconds (24 hours). When the duration of the day is increasing, the Earth is spinning more slowly, and when it is decreasing and becomes a negative number, the Earth is spinning more rapidly.
Scientists say that the speed of the Earth has accelerated in recent years. Earlier, the shortest day was recorded on July 19, 2020. Then the day was 1.47 milliseconds shorter than 24 hours. At the same time, in the year 2021, the Earth continued to rotate rapidly, although the shortest day of the year in 2021 was partially longer than in 2020. But, In the year 2022, things have intensified again. However, scientists are yet to find out the reason behind this unusual phenomenon and why it is happening to the planet. There is speculation that this is related to the impacts of climate change and global warming, and it could be related to processes in the Earth's inner or outer layers, oceans, tides, and constant melting and refreezing of ice caps.

Technology is a useful servant, but a dangerous master, it was rightly said. Electronic devices have grown into an inevitable part of our daily lives.
