Where did the moon come from and what is it?
Section: Astronomy and Astrology
The article presents the theories of the origin of the Moon, as well as lists simple reasons why it is worth studying this space object
What is the Moon?
A piece of Earth?
Or maybe an alien spaceship hidden from the human eye is a spy?
The moon is not a planet, it is just a space satellite of the Earth and it is the only one of its kind.
The moon is the second brightest object in the Earth's firmament after the Sun.
It is located between the Earth and Mars, that is, the fourth from the Sun.
Since the most distant times, the moon excites the imagination of people.
She was credited with a very strong, sometimes mystical, influence on the Earth and its inhabitants.
Now it is no secret that it has a certain effect – it is the force of gravity, thanks to which the tides occur.
However, it remains a mystery where our neighbor came from.
There are currently several versions on this score.
Theories of the origin of the Moon
The first of them says that the Moon is a huge fragment that broke off from the Earth about 4 billion years ago, which left in its place a huge depression where the Pacific Ocean is now located.
According to supporters of this theory, this happened as a result of the collision of a planet the size of Mars with Earth.
But if the Moon is a fragment of the Earth, then why is their composition so much different (it is known that there is absolutely no iron on the Moon, while the Earth's crust is very rich in iron ore).
It turns out that this theory explains this as well.
During the collision, molten iron flowed out of the core of an unknown planet, which spread over the surface of the Earth and absorbed into its crust, The moon, having broken off, remained without iron.
According to another theory, the Moon is a small lonely planet wandering through space, which was attracted by the gravity of the Earth.
However, this theory looks unlikely if we consider it from the standpoint of dynamics.
The moon is not so light as to be attracted by the Earth.
The gravity of the Earth would only change the trajectory of the moon.
Another hypothesis suggests that the Earth and the Moon were formed simultaneously, attracting objects surrounding and flying past them.
But this theory cannot explain the difference in the composition of the rocks of the Earth and the Moon.
And finally, the most fantastic theory.
She says that the Moon is an artificial disguised satellite of the Earth, launched from remote parts of space to observe the inhabitants of our planet.
The birth of this theory was caused by an unusual event recorded by a seismograph that was left on the moon by American astronauts.
It consisted in the following.
When the separated stages were dropped to the surface from the space probes, the Moon vibrated for several hours, which could only happen with a body having the shape of a hollow sphere.
Currently, the validity of none of these theories has been proven, but it has not been refuted, and now more and more countries are joining the study of the Moon.
And why do you need to study the moon?
Firstly, due to the fact that the gravity on the Moon is six times less than on Earth, it is an excellent launch pad for launching spacecraft exploring the far reaches of space.
Secondly, there are a lot of resources that will be completely depleted on Earth very soon.
Thirdly, the soil of the Moon is very fertile, even more so than on Earth, but no water has been found there yet and there is no atmosphere.
That is why it makes sense to study the moon, and maybe it's worth trying to build settlements or inhabited stations there with the necessary life support equipment.
But for now, these are just fantasies that may never become reality.

Conduct an experiment .
Say bad words to the moon and you will see what will happen to you .
It reacts to words addressed to it , which means it is a living organism, an extraterrestrial intelligence that we are looking for .
Life on earth was a long time ago , but with the arrival of the moon , the tides began to throw plankton ashore and under the influence of ultraviolet rays, cells began to divide, this is the beginning of intelligent life .
We are all her children, sleepwalkers .
She controls us .

Damn it, they've already found out that there's a spy.
