Researchers identified a star that got too close to the "dinner table" and was swallowed up as well
At the center of a distant galaxy, 300 million light-years away from Earth, a giant black hole was observed during a routine meal. It began to swallow gas from a huge disk that surrounds it, like water around a drain opening. As the gas is drawn into the black hole, it heats up and emits radiation from the visible to the X-ray range, clearly seen by the researchers here at the end of the telescope.
In most systems of this type, it is not uncommon for the intensity of the radiation to increase or decrease even by a factor of 10, this is due to the changes in the rate of material being swallowed by the black hole. But a research team led by Dr. Benny Terchentbrot and Dr. Yair Harkabi, both from the Department of Astrophysics at Tel Aviv University, detected a strange change in the behavior of the black hole known as 1ES 1927+654. They detected a disturbance in the black hole's material ingestion process. It is possible that a star that got too close to the "dining table" caused a disturbance, and was also swallowed up.
unusual behavior
The ASAS-SN sky survey measured a 50-fold increase in the intensity of radiation in the visible range, coming from the vicinity of the black hole. Observations made by the researchers using the robotic telescope network Las Cumbres, showed rapid changes in the form of the radiation and its source.
A few weeks later, the team pointed NASA's Swift, NuSTAR and NICER space telescopes, and the European Space Agency's XMM-Newton at the black hole. The researchers noticed a 10,000-fold decrease in the intensity of the X-ray radiation from around the hole. "We've never seen a black hole behave like this," says Dr. Trachtenbrot. "Usually, the intensity of radiation from the surroundings of a black hole is directly related to the rate at which it absorbs matter. Therefore, the sharp increase in radiation in the visible range told us that the rate of absorption was increasing, but on the other hand, the decrease in X-ray radiation signaled to us that the rate of absorption was actually decreasing."
Crossed the line of good taste
"It was so strange that at first we thought there might be something wrong with the data," says Dr. Claudio Ricci, of the University of Diego Portales in Santiago, Chile, who is now leading follow-up research on the black hole. In this study, the team of researchers investigates the possibility that a rogue star got too close to the black hole, disintegrating due to the strong gravitational forces that prevail there. In such a scenario, the remnants of the star may crash into the disc of material that was there before, heat it (thus increasing the intensity of radiation in the visible region), and scatter some of it (thus reducing the X-ray radiation). "We have already seen several times black holes disintegrating a star that gets too close to them, but we have never seen this happen next to a black hole that already had a disk of material around it, and the resulting collision," says Dr. Hakabi.
Almost every galaxy contains a supermassive black hole at its center. Such a black hole can reach a mass of a million or even a billion times the mass of the Sun, but it is still not entirely clear to scientists how they grow to these enormous masses. One possibility is that black holes do this by continuously absorbing matter that is orbiting around them. Recently, the possibility that accelerated ingestion of stars could supply a large enough amount of material to the black hole has begun to be explored. The current event in the 1ES 1927+654 system provides a first glimpse of the combination of the two processes.
Although a rogue star appears to be the main culprit, researchers note that this may not be the whole story. One of the mysteries associated with the event is that the weakening of the X-ray radiation did not occur "smoothly". The NICER space telescope, stationed on the International Space Station, detected dramatic increases and decreases in X-ray radiation, sometimes 100-fold within a few hours. Such rapid changes, which occur throughout the radiation weakening process over several months, have never been observed before. "There are still many puzzles in the data," says Dr. Ritchie, "but it's exciting, because it means we're learning something new about the universe."

What Eli and others think is probably true. There is a transition of matter and energy from one world to another. It's just that we don't have the mathematical tools to analyze and define the phenomenon. The dimensions of this phenomenon are enormous beyond imagination.
Summary of the theories presented here: In my opinion, the process of stars being swallowed by black holes is continuous and continues for billions of years until the black hole is no longer able to contain all the material it swallowed, collapses and explodes in what we know as the big bang, and the entire process of creating planets starts from the beginning. As mentioned, all this is in my opinion only.
Or some object passed between the hole and us and hid. At such a huge distance any object like a star or a cloud of dust or exotic matter can cause, and now also Musk's satellites...
By the way, the local black hole - its horizontal jets were discovered at the poles of the galaxy, in the form of a halo. It seems that it also emitted energy in the past (millions of years).
My question after the black hole swallows where what happens below it.
The article talks about 300 million light years how there is a telescope on earth that can see to such a distance.
It's a delusional soul, only a supercomputer can calculate such a distance.
This is not the end
And not the beginning.
...and it's not the beginning of the end either...
This is actually just the end of the beginning…….!
...there is no end to the universe..
And there is no beginning...
There is a formation!!!!
I wonder if this star will emerge somewhere else (a wormhole) or if it is digested...
Eli, an interesting thought but does not solve the question where did the first universe come from? A bit reminiscent of the 'simulation theory' which also does not answer the question where did the creators of the simulation come from? Perhaps considering all these, it is better to assume that our universe is the first and is the real one after all.
In my opinion, the big bang is the result of a black hole that swallowed/ate too much material/stars and reached monstrous dimensions that caused it to collapse and explode. In that case, there is no end to the universe or at least the end of the universe is not the end we know and apparently there are also an infinity of black holes and the process of the explosion of a black hole can also occur outside the "boundaries of the universe" we know.
