We have heard this time and again and yet again and no one seems have any mannerism of doing anything about it. Although, the fact remains that time as a concept is manmade and we could have had as many hours as we liked. But that’s for another discussion.
For decades Indian women have been praying to the moon for the longevity of their husband’s lifespan. Apparently the moon has heard. Husbands don’t celebrate as yet. The moon has decided to drift further away from the planet Earth in the paradigm of space, hence impacting the 24-hour day ritual we have all being groomed to believe as the paradigm of time. Our routine day is about to get a tad bit longer.
Researchers at Columbia University and the University of Wisconsin-Madison have figured that more than One Billion Years ago, the day used to last only 18 hours. And as the moon slowly paces away from the earth, the days tend to become longer. As the moon moves away, Earth’s rotation on its axis slows down like a spinning figure skater who slows down as their arms stretch out.
Today, the moon is at a distance of 3,84,000 kms from Earth but is moving away at a pace of 3.82 cms a year. And because Earth rotates around its axis three hours faster than the moon, the tide bulges created by the Moon’s gravity speed up the moon. And thus, moon’s own gravitational pull slow’s down Earth’s rotation. This interplay between the Earth and the Moon will continue for millions of years, extending the length of the day by 74,000th of a second per year. Well, if you are looking at adding another hour of sleep to your daily slumber, at that pace its not going to happen in our lifetime for sure.
But then, the paradigm of space and time is never in days, hours and seconds but in millions and billions of years. There are speculations that the moon was born about 4.5 billion years ago when a Mars sized body slammed into Earth.
