newly, Astronomy scientists of the University of London, in England, stated that the Moon has a direct impact on terrestrial life due to its delicate gravitational relationship with the Earth. The star makes the days here longer. What’s more, research estimates that 4.5 billion years ago, days only lasted 13 hours! Strange isn’t it?!
Better understand the extension of days
According to SpacePlace, NASAThe rotation of our planet on its axis is known as the solar day.
Thus, depending on the gravitational relationship of the planets to the Sun and their natural satellites, each solar day has a different duration.
BBC science journalist Richard Gray said that the gravitational relationship between the Earth and the Moon also determines the movement of high and low tides.
“These tides are, in fact, ‘bulges’ of water that extend in an elliptical shape toward and away from the moon’s gravity,” said the reporter.
The moon exerts a gravitational force on the Earth, drawing water from the oceans toward itself. This drag causes water to swell on the part of the Earth facing the Moon, which causes high tides.
In other words, the moon’s gravity pulls Earth’s water toward the moon, causing the water to rise in some places (high tide) and sink in others (low tide) in a daily cycle.
But after all, how does the moon change our days?
The fact that the Earth is spinning on its axis much faster than the Moon does creates a great deal of friction in the ocean basins, which are moving below the surface.
In this way, when the Earth is moving a little faster than the Moon in its orbit, it tries to compensate for this difference.
This situation depletes the energy of the Earth’s rotation, slowing down the speed of the planet’s rotation around its axis. That is, the moon makes the days longer.
However, the research highlights that the Earth’s “curb” is imperceptible to living organisms, so we’ll continue to live 24 hours a day.
