A recent study has found a solution to the mystery of the “supermassive” black hole, which was announced last month, shooting through space at top speed, leaving behind a chain of stars 200,000 light-years away.
And it suggested that this hole is actually a chain of stars that the Hubble Space Telescope observed, and it is a relatively common type of galaxy known as “flat” or “thin” galaxies.
And the “Daily Mail” newspaper considered that this conclusion challenges the theory that the stars are the result of a massive black hole colliding with gas in front of it and leading to the formation of stars.
According to the conclusions of researchers from the American University of Yale, two galaxies may have merged about 50 million years ago, causing the rotation of two supermassive black holes around each other.
However, a third galaxy with its own black hole collided with this group, which led to the creation of an unstable and chaotic trio, which led to the expulsion of one of the black holes at a tremendous speed, as the hole observed by “Hubble” could travel the distance between the Earth and the Moon within 14 one minute.
Contrary to expectations that the cosmic monster devours the stars in front of it, however, the researchers observed the opposite results, as they spotted the stars behind it.
Analysis showed that these stars weigh as much as 20 million stars and span 200,000 light-years – twice the diameter of the Milky Way.

alternative theories
Although runaway black holes are believed to exist, they require a large number of exceptionally complex conditions for their occurrence.
That is why scientists around the world have begun to explore alternative, simpler theories that could explain what Hubble discovered.
This led researchers at the Canary Islands Institute of Astronomy to conclude that this unusual structure of stars may in fact be a galaxy without an edge-on bulge.
These are known as thin or flat galaxies and are scattered throughout the universe. It has a thin rotating disk of gas, dust, and stars at its center, and is shaped into two main types: spiral and lenticular.
Lead author Jorge Sánchez-Almeida said: “The motions, size and quantity of stars are consistent with what has been seen in galaxies within the local universe. It is a great satisfaction to find a solution to this mystery; The new proposed scenario is much simpler.”
“On the other hand, it is also unfortunate, because runaway black holes are expected, and this may be the first to be noticed,” he noted.

What did the results show?
The researchers reached their conclusion by comparing the impact of stars and their very narrow structure with a local galaxy called IC5249, which contains a mass of stars similar to what Hubble discovered, according to the study published in the “Astronomy and Astrophysics” journal.
“When we analyzed the velocities of this distant structure of stars, we realized that they were very similar to those obtained from the rotation of galaxies, so we decided to compare a much closer galaxy, and found it to be extraordinarily similar,” said study co-author Mireya Montes.
Researcher Ignacio Trujillo added: “We also looked at the relationship between the supposed galaxy’s mass and its maximum rotational speed, and discovered that it is indeed a galaxy behaving like a galaxy. It’s an interesting object, because it’s a very big galaxy at a very great distance from Earth, where the majority of galaxies are smaller.”
Despite the new theory, Yale researchers still hope to use NASA’s James Webb Space Telescope to study the structure further and confirm their own hypothesis.
But for now, this cosmic mystery appears to have a much simpler – if less exciting – explanation.
