Earth's rotation is faster: The new challenge of time
How are you all, friend? Since childhood, we all know that the Earth revolves around its axis in 24 hours or 86,400 seconds. But do you know that recently scientists have found that the Earth is moving a little faster than before! After hearing this, many people may be surprised that some milliseconds seem less to make the world completely rotated. In today's simple article, I will explain the matter, what is happening, why this is happening, what is the effect on our daily life, and why scientists are so excited.

The speed of the Earth's rotation is not stable at all. Sometimes, due to the effects of tidal forces, the distance of the moon, or due to various movements inside the earth, this speed increases slightly and sometimes decreases. In 2025, it is seen that in July and August, only 1.3–1.5 milliseconds are decreasing, that is, the length of the day is decreasing slightly. It is not worth noting in our eyes or our daily life, but it is a major issue for various institutions such as satellites, computer networks, banking and GPS.
A standardized method called UTC is used to keep a track of time, relying on more than 400 nuclear watches worldwide. But this slight change in the rotation of the Earth was first used to restore the balance regularly by adding leap seconds. In the case of years of leap, an additional day is added every 4 years! Now scientists have a new idea, because the Earth is moving a little faster this time, it can take a negative leap second (leave a second), which has never happened before.
In fact, scientists are skeptical about how risky this system can be. There have already been technical problems with positive leap seconds, especially with large technology and communication companies.
There is no straightforward answer to this question. The pull of the moon, the movement of molten metal inside the Earth, major earthquakes or melting ice, and even climate change also have an effect. Scientists believe that if the ice near the poles melts, the Earth's gravitational field changes slightly, which can cause the Earth's rotation to increase or decrease slightly at different times.
For those who work in sectors such as global borders, millions of communications, and financial transactions, these few milliseconds are also very important. If not done on time, millions of dollars can be lost or there can be technical disruptions. That is why scientists are paying extra attention to the matter and focusing on time.

The length of the day is changing slightly, the Earth is moving a little faster, this news has almost no adverse effect on the lives of ordinary people. But for the scientific world, it is quite exciting. Trying to understand the mystery behind these events, we can understand how changeable the nature of the world and the course of creation are. New calculations may come about with time in the future, perhaps our time-measuring technology will become more modern.
Everyone stay well, may you also enjoy this simple-complex change in the world!
