The day on Earth will be 25 hours long as the planet slowly rotates

British scientists calculate in the future, a day on Earth will be 25 hours long because the rotation speed around the planet's axis is getting slower and slower.

British scientists calculate in the future, a day on Earth will be 25 hours long because the rotation speed around the planet's axis is getting slower and slower.

The ancient records of Babylon civilization, China, Greece and Arab pointed out that the Earth is turning slowly. Through a review of the natural phenomenon (including eclipses and eclipses) from 720 BC, scientists concluded that every 100 years, the day on Earth is becoming nearly two milliseconds ( 0.002 seconds), the International Business Times reported.

Scientists have long recognized that the Earth is slowing down. When the new planet was formed, one day was only 6 hours long. About 200 million years ago, under the dinosaurs, the day was 23 hours long. After 200 million years, scientists estimate that it will be 25 hours long.

To understand exactly how the Earth's rotation has changed over the past few thousand years, the research team from Durham University and Britain's HM Nautical Almanac Office of astronomical research reviewed the old records. date of 2,700 years.

Starting from the Babylonian record, the team explored how this ancient civilization measured the start and end time and location. They used documents collected from China, Greece, Europe in the Middle Ages and Arabs to create "the list of the most complete observations to study the difference in the rotation speed of the Earth from in 720 BC ".

Scientists compare this record with the computer model showing the real time and place of the nature thousands of years ago if the Earth's rotation did not change. The discovery published yesterday in the journal Proceedings of the Royal Society A indicates that the Earth's rotation slowed about 1.8 milliseconds after every century.

This slow rotation is partly due to tidal forces. Earth's rotation speed is faster than the Moon. The Moon's gravity acts on the tide, slowing down the Earth's rotation. "Assuming that the tidal force force measurement in the Earth-Moon-Sun system is accurate, we conclude that this mechanism alone is not sufficient to explain the observed slow rotation speed for 2,700 years. over, "the team said.
