What is the meaning of increasing or decreasing the speed of Earth’s rotation? How much reduction in speed of Earth’s rotation has been recorded by scientists? Has Earth’s rotation speed decreased earlier? If yes, when and how much? Among all this, an important question is that what will be the effect on the life of the common people due to the speed of rotation of the earth being fast or slow? All these questions have been in existence for some time now and the biggest reason is that scientists claim that the speed of rotation of the earth has increased. That means the earth is rotating a bit faster.
- The speed of rotation of the earth has increased. That means the earth is rotating a bit faster.
- A negative leap second can be added internationally to solve the formula for increasing Earth’s speed and shortening the length of day.
- 1.59 milliseconds was recorded across the day on June 29 due to the Earth’s rapid rotation.
What does increasing or decreasing the speed of rotation of the earth mean?
In the solar system the earth revolves around the sun and also rotates on its axis. One revolution of the earth around its axis is completed in 24 hours. However, on June 29 this year, a day on Earth was reduced to less than 24 hours. That is, the speed of rotation of the earth has suddenly increased.
A decrease of 1.59 milliseconds was recorded across the day on June 29 due to the rapid rotation of the Earth. Although this reduction is insignificant compared to 24 hours but its impact on human life is very high. One complete rotation of the Earth affects the entire duration of sunrise and sunset. In the long run, these major changes can affect humans as well as the surrounding environment.
What would be the effect on people’s lives if the earth’s rotation speeds up or slows down?
The more or less rotation of the Earth will cause a slight difference in the length of the day and will not make a big enough difference to be recognized in the lives of ordinary people. However, if the length of the day varies over many years, it can cause very large changes to the Earth in the long run.
- If the Earth’s speed is faster than before, it will affect the atomic clocks that measure the exact time on the planet. These clocks are used in GPS-linked satellites around the world and would be difficult to change if the time of day changes. The effect of this is that if the Earth rotates rapidly, the location of a person present at some location will be transmitted from the satellite a few seconds late. A difference of even half a millisecond can show a difference of up to 10 inches or 26 centimeters at the equator. If the speed of the Earth’s rotation continues for a long time, GPS satellites will gradually become useless.
- Another impact will be on the communication tools people use on a daily basis. Smartphones, computers and other communication systems keep themselves synchronized through Network Time Protocol (NTP) servers. The speed of the Earth’s rotation and even slight delays in satellite communication relays will cause time differences in different locations. If this process continues for many years, scientists may have to change the time system as well. Researchers say negative leap seconds can now be added internationally to solve the formula for speeding up the Earth and shortening the length of the day. This means that International Time may be reduced by one second every few years to compensate for the millisecond change in the length of the day.
Leap Year Formula
This type of arrangement has existed on Earth before. A year on earth is considered complete when the earth completes one orbit around the sun. This period is currently 365 days and six hours. But according to the English calendar, a year is considered to be 365 days. Now if the additional time of 6 hours taken by the earth is added 4 times, this time comes to one day. That is why the world has a leap year every four years. One day has been added in February and it is 29 days instead of 28 days.
