Why did the length of the day on earth become longer? Scientists are confused
According to atomic clocks and astronomical observations, Earth’s days have become surprisingly long and this situation has puzzled scientists.
Scientists believe that this change will have a profound impact on our accurate timekeeping and technologies such as GPS that are important in our daily lives.
According to scientists, over the past few decades, the speed of the Earth’s rotation in its orbit has accelerated, which determines how long our day will be, but if you remember, we had the shortest day in the last 50 years in June this year. has spent
Despite this record short day, this acceleration has slowed again in 2020 and Earth’s days have once again become longer.
The tidal friction caused by the Moon slowed the Earth’s rotation millions of years ago, and every 100 years the Earth’s speed increases by 2.3 milliseconds.
Earth’s fastest rotation breaks record for shortest day
According to scientists, the relationship between the inner and outer surface of the Earth is also very important because even a very powerful earthquake can cause a difference in the length of the day, as happened after the 2011 magnitude 8.9 earthquake in Japan that shook the Earth. The rotation speed was accelerated by 1.8 microseconds.
After scientists at the UK’s National Physical Laboratory identified the shortest day, there is concern about what effects a possible change in the speed of the Earth’s rotation on its orbit could have on the environment. At the same time, there is concern among technology companies that leap seconds could affect online platforms.
Recently, Mark Zuckerberg’s technology company Meta has also joined other companies in calling for the end of Leap Second, saying that it has already been used 27 times in recent years and that number is enough.
He says how many internet platforms have been affected by the recent leap second formula.
