There will be 25 hours in a day reason will be moon

There will be 25 hours in a day reason will be moon

A study published in Proceedings of the National Academy of Sciences, shows that 1.4 billion years ago, a day on Earth lasted just over 18 hours.


A day lasted just 18 hours around 1.4 billion years ago because the planet rotated faster, experts calculated. This is at least partly because the moon was closer and it influences how Earth turns.

The moon is moving away from our planet at just 3.82cm a year, which is having a small, but measurable effect on Earth’s movement.

Small, initial variations in these moving parts can propagate into big changes millions of years later

Researchers said that In around 200 million years’ time, every day on our planet will be 25 hours long

It’s all to do with the moon moving away from our planet, researchers say.

The scientists studied evidence in Earth’s rock record to trace changes in Earth’s climate.

The researchers describe it as astrochronology, a statistical method that links astronomical theory with geological observation.

Stephen Meyers, a professor of geoscience at the University of Wisconsin-Madison and co-author of the study, explained: ‘As the Moon moves away, the Earth is like a spinning figure skater who slows down as they stretch their arms out.’

Dr Meyers said, ‘One of our ambitions was to use astrochronology to tell time in the most distant past, to develop very ancient geological time scales
‘We want to be able to study rocks that are billions of years old in a way that is comparable to how we study modern geologic processes.’

Earth day will not become 25 hour long in our life time, it may happen in around 200 million years time, if we humans do not destroy earth before that.
