The Tide Turns

We are now in the 21st century and we know that the earth is not the centre of the universe. 

We are sure that the whole universe does not revolve around our earth, as humanity once believed. 

While the earth revolves around itself, it also revolves around the sun. 

The moon continues to revolve around the earth as it has done for millions of years.

We also know that the earth's axis of rotation is tilted 23° 26′ 26′ 11.3″ compared to its orbit. 

So far, almost everyone is now familiar with this information. 

Although exactly how much the axis tilt is not always in mind, I think we all know that at least the earth has an axis tilt.

***

What is less well known is that this axis tilt has fluctuated between 22.1° and 24.5° for 41 thousand years due to the slight wobble of the earth's rotation around itself. 

This wobble is the kind of wobble that makes a spinning top shake its head slightly during its rotation.

I think we also know that the earth rotates around the sun on an elliptical axis.

Although many of us think that this elliptical orbit causes the seasons, the real cause of the seasons is the earth's axis tilt. When the sun's rays reach the earth's surface perpendicularly, it causes the surface temperature to rise, i.e. summer months, and when they reach obliquely, it causes winter months.

Therefore, there are both winter and summer months in the southern hemisphere. 

In addition, the elliptical orbit also has an effect, of course, since it coincides with the close part of the elliptical orbit, the winter months in the southern hemisphere are not as harsh as in the northern hemisphere. 

In other words, the elliptical orbit around the sun also has a small effect on the seasons.

This second stage information is generally known to those interested.

Well, the earth revolves around itself and the sun, but does anyone know the direction of its rotation on the orbit?

We all know that the earth's rotation is from west to east.

Because the sun rises in the east. Logically, since the sun does not revolve around the earth but the earth revolves around itself, the earth should rotate from west to east.

Until humanity reached a consciousness, they called the direction of sunrise east and the direction of sunset west. He thought that the sun rises and sets again and again every day.

This is the case in almost all languages.

The English word "east" comes from the Middle English word "est" and its Old English form "ēast" came into English from the German language. 

Yes, "aus-to" or "austra" means east in German, and Austria is actually a German name for the country in the east. 

I think Australia was given as a name with the same logic.

Again, "west" in English is a word from German, but the etymological dictionary states that this word came into German from the languages of the Roman Empire.

In French and Catalan languages, Italian and Spanish, this word exists in a very similar form. It means the setting of the sun. So it has the same meaning as ours. The words used in other European languages are various accents of the same word.

The ancients thought that the sun revolved around the earth, but Galileo somehow showed that this was not the case.

He concluded that if the sun rises in the east and sets in the west, it means that the direction of the earth's rotation is from west to east.

However, another question still haunts me in this regard. 

In what direction does the earth orbit around the sun?

This actually depends on where you look at the solar system. 

For example, if it rotates clockwise when you look at the system from the top, it will rotate anti-clockwise when you look at it from the bottom.

I think it is not possible to know the top and bottom since there is no benchmark we can take as a reference point to determine the concepts of top and bottom. 

In this case, it does not matter in which direction the earth rotates around the sun.

***

I'm still not convinced. 

Since the solar system is inside the Milky Way galaxy, it means that the whole system rotates together around the black hole at the centre of the Milky Way galaxy. 

In this case, according to the direction of rotation of the entire solar system, the concept of upper or lower can be considered.

Anyway, this issue is not very important, but there is another axis of the earth's rotation around the sun. 

That is the radial axis of the elliptical orbit.

When the earth rotates around the sun, does it rotate like a spinning top drawing a large circle on the ground during its rotation, or does it rotate around its elliptical axis, that is, does it make a radial rotation?

I'm more interested in the answer to this question.

Do not say what strange things interest you, human beings have reached this level by wondering such questions, the answer to a simple and strange question can be very complicated. It may open the way to other subjects that you have never noticed.

Yes, it seems to me that the moon is orbiting the earth, but is it also orbiting the elliptical orbit of the earth around the sun? 

In other words, could it be that the earth is travelling on its elliptical orbit and at the same time it's orbiting radially around itself?

Actually, we have a reference to understand this.

The north pole star!

If the earth were rotating radially on its orbit around the sun, there would be no star like the pole star, whose position from the earth is almost fixed.

So the earth must be spinning like a spinning top on a table in an orbit with the sun at its centre. If it had a radial rotation on its orbit, the direction we call north during the year would not turn towards the pole star, but towards another star.

Look how easily answers to questions are found when we use a little logic.

Do you know where such a question came to my mind?

In an artificial video, it was shown that the earth makes a radial rotation as it revolves around its orbit.

It stuck in my mind; until today, in the diagrams showing the solar system, our orbit was always shown in a plane like the plane of a tray. This video confused me.

No, the video is wrong! The rotation of the system should be in the horizontal plane, not like in the video!

As for the position of the pole star, no matter how big our orbit around the sun is, since the pole star is quite far away, it does not move much during the year.

In fact, the pole star appears in different places over a period of 25 thousand years, as if it regularly makes a certain circular rotation. But since this period is long enough, we see it in the direction we call north for now.

Anyway, I'm really relieved. 

The cycle keeps turning as we know it.

One day this cycle will turn again.

The wheel will turn, the handle will turn, the day will come when the reckoning will turn.

My love and respect to everyone from Moscow.
