The beginning of the current decade was marked by a very remarkable astronomical event - the legalization of the Nibiru theme, which before that official astronomers spoke only among themselves in smoking rooms and, mainly, in a whisper.
As a result, more and more people began to study the topic every year, some publications appeared in official scientific journals, and today there are hundreds of such articles.
According to the astronomers searching for Nibiru, the mysterious "Planet X" exists, since there is a lot of evidence of its existence. And the most important proof is the orbits of trans-Neptunian objects that form the Kuiper belt and the Oort cloud.
In view of the great remoteness of such objects, not very many have been discovered yet, nevertheless, the orbits of already discovered asteroids and minor planets do not fit into the mechanics of the known solar system. So there must definitely be something else here. And it's very hard.
On the subject of this “something else” there is a long and not very productive debate, although, according to most researchers, “Planet X” is most likely a twin star of the Sun, which did not gain at birth a mass sufficient to trigger thermonuclear fusion. That is, the star is dark and it is more difficult for her to find than a black cat in a dark room, which, perhaps, is not even in this room.
However, the twin star is only one of the theories, since “Planet X” can be a completely invisible, physically non-existent quantity, which in mechanics is called the CENTER OF MASS.
How the center of mass works is clearly seen in the example of the Earth-Moon system. Although most people believe that the Moon revolves around the Earth, this is actually not the case, since both the Earth and the Moon revolve around a common center of mass, which is 4500 km from the center of the Earth:

A similar situation occurs with the Sun, which also revolves not around itself, but around the center of mass of the solar system:
In light of these circumstances, some researchers of Nibiru suggested many years ago that Nibiru is, as it were, the real center of mass of the solar system, which for some reason from time to time begins to migrate, causing chaos in the planet's orbits and causing the Earth's lithosphere to tremble.
Although the theory itself turned out to be very interesting and almost wonderful, the problem with this theory is that we do not know anything about trans-Neptunian objects. That is, how far the Oort cloud extends and what is its mass. Therefore, the officials took the "known" to them the mass of the Oort cloud, which is, as it were, several masses of the Earth (which is very small) and recalculated the position of the center of mass of the solar system. They got something like this:
After such a result, which upset the nybirologists, the topic of the wandering center of mass was somehow almost not raised, however, as sciencealert reports, astrophysicists from the University of Cambridge in the UK also became interested in the topic of the center of mass.
To begin with, they loaded the generally accepted official data on the Oort cloud into a supercomputer. That is, the cloud is spherical and has a mass like several Earth masses. As a result, the center of mass of the solar system has moved quite a bit from the center of the sun.
However, further astrophysicists began to change the mass and shape of the Oort cloud, since in fact no one knows anything about its mass or its shape. The cloud may well be elongated or even in the form of a dumbbell. And its mass may not only exceed the mass of Jupiter, but be comparable to the mass of the Sun itself.
And as soon as the computer began to receive new data, all the strangeness of the transuranium objects immediately fell into place. That is, the Oort cloud can be viewed as a “virtual star” located somewhere in the region of Jupiter - where its center of mass is concentrated. This “star” brings dissonance into the solar system.
And if we further assume that some distant invisible force (for example, a black hole) begins to act on the Ooort cloud, it will begin to change its shape, which will result in an even larger and sharp shift of the cloud's center of mass. And all the planets of the system, including the Sun itself, will jerk from their places and will run after this center of mass like iron balls after a magnet.
It is impossible to say how realistic this version of the development of events is, since the center of mass is an invisible thing, and we do not know the exact mass of the Oort cloud. However, as computer modeling shows, this is exactly how everything can be in reality. That is, not some new mysterious planet Nibiru enters the solar system, but simply for some reason the center of mass of the solar system began to rapidly shift and all the planets now revolve around it in some completely unthinkable crazy orbit.
True, in order to see this, an observer in the Solar System will need some kind of bright and fixed reference point located in relative proximity, only against the background of which one can see the movement that has begun. So far, astronomers do not have such a reference point.
