In the future, it will be 25 hours long because the Earth slows down

Days are becoming longer. For amateur people, this means that in the northern hemisphere in the summer it will be longer than in winter. But geographers understand that this sentence is longer than k

Days are becoming longer. For amateur people, this means that in the northern hemisphere in the summer it will be longer than in winter. But geographers understand this sentence as the day will be longer not only in the spring.

The first and most important reason is the Moon. The attraction of the Moon creates stable waves for Earth's oceans and abyss. According to the German newspaper Suddeutsche Zeitung, our planet seems to be becoming more stagnant.

The earth is like a dancing skating artist. In order to reduce the rotation speed, the artist has to extend his or her hand. That is why in the future there will be 25 hours relatively far from a day on Earth. An English astronaut tried to prove that Earth's rotation had slowed since 700 BC. He studied clay engravings and historical documents that recorded information about eclipses and eclipses. He uses that information to calculate the transformation phase of the Earth.

When prehistoric creatures settled on Earth about 530 million years ago, it was 21 hours a day. The dinosaurs that lived 100 million years ago also took turns in turn after 23 hours. This can be observed from coral sediments very clearly. The coral marks the timeline and every year creates new layers of sediment. The thickness of the sediment varies depending on the season.

Thus scientists have calculated the time of the spring. This period has slowed down throughout the history process. Around 530 million years ago the Earth revolved around the axis faster than now, but revolved around the Sun at a steady speed. At that time, the number of hours in the year is the same as it is now but it is 420 days. Richard Stephenson of Durham University (United Kingdom) told History of Astronomy that according to reliable sources, history has seen the speed of the Earth's rotation slow.

Stephenson has drawn conclusions based on descriptions of hundreds of eclipses and eclipses over the past 2700 years. The Babylonian clay engravings during the pre-Christian period clearly demonstrated the slowing of the Earth's rotation. Babylon scientists used wedge-shaped characters to accurately record the time and place of astronomical phenomena.

Besides, Stephenson also studied more documents from China and Europe. Every 300 years, people everywhere can observe a total solar eclipse. When the Moon is between the Sun and Earth, a total solar eclipse will occur within minutes.

Accurate information about the start date and time as well as the end of the solar eclipse are recorded regularly. That is enough for astronomers to determine the exact location of the Sun thousands of years ago. The tables used to recalculate the Babylonian calendar were also useful at some point.
Astronomers use data about the position of the Sun in historical records to restore the picture of our planet's slowdown.

Because the orbits of the Earth around the Sun are not related to Earth's orbit around its axis, astronomers can calculate the independent time period - called Earth Time. The slowdown in the Earth's rotation can be seen if we compare Earth Time (TT) and Space Time (UT).

UT is a common time based on the Earth's rotation period and is determined by the Sun's position relative to the Greenwich Mean Time (GMT) standard (Greenwich is a UK city). It is necessary to calculate this time later because every few years during the transition period between this year and another year is a second more redundant.

Richard Stephenson used historical records to determine the relationship between two transfers. The difference between UT and TT depends on how long the eclipse or eclipse occurred. Therefore, every millennium a day will be longer than 2/1000 seconds. The measured and determined information from satellites has proved this. So every Babel ceremony will be shorter than 4/100 seconds a day.

However, Stephenson also tried to identify this tiny difference based on confusion about UT. Since 700 BC, there are about 1 million days shorter than the present time. So if we live in that time, we will have to shorten the clock to 7 hours.

The last few years are an exception. During this period, the day is almost no longer. The Earth rotates at a relatively stable speed. It is possible that the Earth's weight change accelerated it, compensating for the deceleration caused by the moon. The devastating earthquake in South Asia and the tsunami then accelerated the Earth's rotation at the end of 2004, and made the day short about 8 milliseconds.

According to the Earth Observation (IERS) Observatory, June 13, 2003 was the shortest day in the last 100 years. Compared to an average of 24 hours a day, it is about 1.5 parts per second shorter.
