[Curiosities] What if the Earth had no moon?

[LosT贼]

Humans have established a close relationship with the moon throughout the ages. The effect of this multi-faceted silver subordinate is clear on our different civilizations, whether in reference to its phases in the calendar, or its role in the ebb and flow and its relationship with global navigation. But let's imagine our planet Earth without a moon revolving around it.
Of course, our nights will be darker and "moon of fourteen" will not be a common term in human languages.
In fact, some scientists believe that had it not been for the moon, there would have been no life on Earth. And the explanation for this is due to the date of formation of the Earth and the moon.
The earth formed about four billion years ago. Scientists suggest that the moon will be between thirty and forty million years later. During that period of the Earth's life, its surface was a vast ocean of lava. There was no land or water. The moon was only twenty to thirty thousand kilometers from the surface of the earth.
The impact of the moon on the earth at that time depended on several factors. The proximity of the moon to the earth played a role in the speed of cooling the earth’s surface. And that by the tidal forces that the moon exerted on the lava. This added to the thermal energy produced by the nuclear radiation from the elements in the Earth's interior, and affected the composition of the surface of our planet as it cooled. And because tidal forces affect liquids more than solids, if the moon suddenly disappears from us, much of the ocean water will move from around the equator towards the poles. Scientists suggest that a similar effect will be an important factor in the formation of the Earth's surface during the solidification of liquid lava.
One of the most important aspects of the moon’s relationship with the earth today is that the moon is fixed to the tilt of the earth’s axis at an angle of twenty-three and a half. What scientists have noticed about the planets Mercury, Venus and Mars is that their axes are less stable than the Earth's. This is due to the absence of a moon, as in the case of Mercury and Venus, or to the small size of the moon compared to its planet, as in the case of Mars. For example, Mars' angle changes from fifteen to thirty-five degrees over the years. Were it not for the existence of our satellite with its current location and size, this would be our case. The seasons of the year would have changed throughout the ages, and the development of life on Earth would have taken a different course.
Finally, it is known that the length of the day is shortening at the rate of a fraction of a millisecond per year. Geophysicists calculate that the presence of the moon and its effect on the movement of the oceans and thus on the rate of the Earth's rotation reduced this rate. If it were not for the moon, the length of the day would have been six to eight hours instead of twenty-four hours, which means that the Earth’s year would have consisted of one thousand and one hundred days to one thousand four hundred days.
