It's not about Antarctica, But, it does show some insight into just how Advanced or how  smart our ancestors were.

Slowing of Earth's spin revealed in ancient astronomers' tablets

The work of ancient astronomers reveals that the Earth's spin is slowing down — though not as much as scientists believed.

Ancient records
Morrison and his colleagues have been working on measuring the Earth's rotation for decades. The new study is perhaps the most comprehensive effort yet, Morrison said, mostly because the ancient Babylonians were so good at keeping records.


By 720 B.C., this civilization, located in what is now Iraq, was keeping records on clay tablets in a writing system called cuneiform. When archaeologists discovered some of these tablets in Babylonian ruins in the 1800s, the language had been lost; it took decades to decipher those original tablets.


Fortunately for modern-day Earth scientists, some of these tablets happened to contain records of eclipses, particularly solar eclipses, when the moon moves between the sun and the Earth, casting a shadow on this planet. These eclipses tended to make an impression on ancient people, Morrison told Live Science. The events also strengthened tides slightly, because the alignment between the Earth, moon and sun meant a stronger pull on the planet and its oceans.


"The descriptions of a total solar eclipse are so graphic," he said, including descriptions like, "When the days suddenly turn to night and the stars appear."

The researchers also collected eclipse observation records from ancient China, ancient Greece and the ancient Arab regions. The timing of the eclipses from these descriptions, however, conflicts with calculations of when the eclipses should have occurred if tidal friction alone explained the slowdown of the planet's rotation. In 720 B.C., Morrison said, the discrepancy was about 7 hours between what the tablets reported and what calculations based on the tidal models would have predicted.

"That discrepancy is the measure of how much the Earth has been changing over this period of time," Morrison said. Working backward from the discrepancy, the team calculated how long the days have lengthened over the centuries. He and his colleagues published their findings today (Dec. 6) in the journal Proceedings of the Royal Society A.
