Have you often complained about how there is so much to do but not enough time in a day to do it in?
Live to tell the tale of the days long enough and you would be able to surpass this issue if you are not willing to take any time management classes.
How? Well, in about a few million years you wouldn’t complain anymore because by then one day on Earth may potentially be 25 hours long!
Researchers have discovered that the distance between the moon and the Earth is also a determining factor when it comes to the movement of Earth.
The farther our moon moves away from us the more our days are lengthened.
Currently, the moon is inching away from us at a rate of 3.82 cm per year and as per calculations a single day on Earth maybe 25 hours long. In about 200 million years’ time.
According to a new study published in the Proceedings of the National Academy of Sciences, a day on Earth used to be only 18 hours long almost 1.4 billion years ago.
This was because the moon had been much closer to the Earth and had a great effect on how the Earth spins around its axis.
Stephen Meyers, a professor of geoscience at the University of Wisconsin-Madison and co-author of the study, explains,
“As the Moon moves away, the Earth is like a spinning figure skater who slows down as they stretch their arms out.”
This remarkable study was possible because of astrochronology which is a statistical method of finding commonalities between geological data and astronomical theories.
Think of it this way, every orbitary body around Earth exerts a force, in some part, on it. This force determines the speed with which Earth revolves around the Sun as well as the speed with which it spins around its own axis.
This force is forever changing because every single entity in space is in some kind of minuscule motion.
These variations, called Milankovich cycles, also decide a planet’s climatic and weather conditions.
These varying records of climatic and weather changes can be physically detected in rocks and soil from millions of years ago.
“One of our ambitions was to use astrochronology to tell time in the most distant past, to develop very ancient geological time scales.”
Dr. Meyers and his team are now aspiring to conduct a research study similar to the modren geological study of rocks but to study the rocks that are at least aeons old.
Previously scientific community and researchers believed that the distance from the Sun is the only determining factor.
Based on the distance from Sun scientists were able to determine a day’s length on Mars, Venus and other planets.
As science progressed it was found that not only the distance from the Sun but also the gravitational pull of the Earth is responsible for the phenomena.
The new research, however, has dug deeper than previous beliefs, however not to reject them but serves as an extension or sub-theory on the subject.
