In 1784, John Michell is believed to have first proposed the concept of the so-called "black hole" - a massive body whose gravitational attraction is so great that the speed required to overcome this attraction (the second cosmic speed) is equal to or exceeds the speed of light. For a long time, such objects were just a frightening fairytale theory, but with the development of astrophysics and the advent of new equipment for observing, black holes became an obvious fact for astronomers.
To date, many objects have already been discovered that astronomers, by indirect indications, consider black holes, including objects inside our galaxy. However, astronomers are most interested in the so-called supermassive black holes, which, according to the theory, are located in the center of galaxies.
In particular, in the center of the Milky Way lies a relatively compact source of radio emission, which astronomers call Sagittarius A *. This object is believed to have a mass of more than two and a half million times the mass of the Sun and its radius is approximately one light hour greater than the radius of Pluto's orbit. Thus, the diameter of this object is about 120 distances from the Earth to the Sun. And astronomers consider this object a supermassive black hole around which the galaxy revolves.
It is practically impossible to observe Sagittarius A *, since a huge amount of dust and gas has been collected in the region of the center of the galaxy, so astronomers have an insoluble task to see an object absorbing light as if through frosted glass. Nevertheless, by connecting 13 of the most powerful telescopes around the world to the study and combining the data they collected in a computer simulation, astronomers were able to obtain unprecedentedly detailed images of the area around the object of Sagittarius A.
However, despite such an impressive success, astronomers were very unpleasantly surprised.
After the discovery of black holes as objects, astronomers discovered that almost all black holes have so-called jets in their structure - compact multidirectional jets of energy and matter, which, for some unknown reason, are ejected from a black hole.

The most powerful and far visible jets are observed in black holes in the centers of galaxies. In this case, the direction of the jets is perpendicular to the plane of the galaxy and approximately coincides with their axis of rotation.
However, even using 13 telescopes and computer simulations, astronomers never found any jet in Sagittarius A *. The only explanation for the observed situation assumes that the black hole in the center of the Milky Way lies on its side relative to the axis of rotation of the galaxy and its jet is directed directly at us.
Since upon learning that we are under continuous concentrated radiation of such a powerful source, the public should be frightened - in the summary of their research, astronomers reassure the public that up to Sagittarius A * 30,000 light years and if something goes wrong there, nothing threatens the Earth right now … However, astronomers, as always and usually, do not say a lot.
First, not everything in this world spreads at the speed of light, and physics suggests even instantaneous interactions. In particular, no one knows for certain about the speed of propagation of gravity. Some physicists believe that gravity propagates with the speed of light, some continue to think that gravitational waves propagate with infinitely high speed, instantly. At the same time, no one knows what gravity is, just like no one knows what else in a black hole is besides gravity.
Second, the time for observing black holes is ridiculously short, and the time that black holes exist is hard to even imagine. Therefore, what the astronomers mean by the thesis “something goes wrong” is not entirely clear. Maybe everything is not the same there for at least 30,000 years, but light and other radiation are only now bringing to us the news of a terrible event.
The only thing that follows from this new discovery and that is well understood is that the solar system is many orders of magnitude more strongly associated with Sagittarius A * than all other objects in the Milky Way. An energy ray from the center of the galaxy is constantly beating at us, so any processes taking place there will inevitably affect us.
The officials, of course, will reassure everyone, talking about the colossal distances, but let's not forget that the mass of Sagittarius A * is generally unimaginable, there are hidden millions of suns, squeezed into the orbit of Pluto.
All terrestrial “civilization” is very, very fragile: it is enough for the Sun to sneeze - and the lithosphere will go through thousand-kilometer cracks. What will happen if a supermassive black hole begins to “cough hard”?
To date, numerous researchers have established that civilization on Earth develops in rather short cycles lasting about 500 years. Local aborigines breed, begin expansion, erect some kind of structures, after which the planet is covered with volcanic ash and a global flood. Those who survive the catastrophe begin to build everything from scratch, perhaps even with practically formatted brains.
The reason for these catastrophic cycles is unknown, but, according to the most logical theory, the cycles of catastrophes suggest Nibiru - that is, some kind of massive body that enters the solar system every 500 years and, as a reaction to its arrival, the continents begin to jump. However, now, in the light of, so to speak, new scientific data, cyclical cataclysms may have a slightly different model.
Suppose there is not only one supermassive black hole in the Sagittarius A * region, and so of them, which is a little smaller, with a period of 500 years, revolves around a more massive black hole. Will this somehow affect the jets ejected by Sagittarius A *?
Of course it will. As has long been shown by geologists - just a small drop in the surrounding flux of gamma radiation (for example, as a result of a distant supernova explosion) is enough for earthquakes to begin on Earth. And what will happen if drops begin in the emission of the jet?
Most likely, what our descendants will describe as “a mysterious global cataclysm that destroyed an apparently developed technological civilization” will begin. Moreover, judging by what is happening with volcanoes and in general with the planet around the world - this "mysterious cataclysm" will soon be in full swing, so we can only follow the development of events.
