Ever Wondered Why Days Are Dragging? Scientists Reveal That It Will Even Be An Hour Longer, What Does It Mean?
The latest study of the planet's tide has recently revealed that the 'tidal braking' is basically resulting in longer days. Astronomers who had allegedly gathered about 3,000 years of celestial records have noted that with every passing century, the day on Earth lengthens by two milliseconds as the planet's rotation gradually winds down. Experts believe that as the earth's rotation slows down, the moon's orbit consequently grows by about 4cm a year.
Can Longer Days Affect Various Time Zones?
According to reports revealed by Daily Mail, for them to have come up with their calculations, researchers at Durham University and the UK's Nautical Almanac Office gathered historical accounts of eclipses and other celestial events from 720BC to 2015. Study lead authors Catherine Hohenkerk, Leslie Morrison and FR Stephenson, had allegedly revealed that the oldest records they found came from Babylonian clay tablets written in cuneiform, with more added from ancient Greek texts, such as Ptolemy's 2nd century Almagest, and scripts from China, medieval Europe and the Arab dominions.
Furthermore, in order to find out how the Earth's rotation has differed from its previous records, The Guardian reveals that the team has compared the historical records with a computer model that calculated where and when people would have seen past events if Earth's spin had remained constant. However, although astronomers have long been aware that Earth's rotation is dragging, they highly emphasize that the primary braking effect comes from tides caused by the moon's gravity. Morrison explains that the heaping up of water drags on the Earth as it spins underneath.
Experts are now found to be convinced that the difference is made by the rebounding of the Earth's surface after the last Ice Age and to changes taking place deep underground at the planet's core. Morrison adds that while their findings can still be considered as unpolished, she claims that there are a number of consistent discrepancies between the calculations and where and when the eclipses were actually seen. Hence, from time immemorial, the Earth has been varying in terms of its state of rotation.
Earth's Days Are Slowly Getting Longer Every Century
Compared to 700 BC, our clocks today may be seven hours late. The Earth's rotation to its axis has slowed down due primarily to the Moon's tidal pull.
