A team of scientists proposes a new theory. that black holes may have a connection with the expansion of the universe Black holes are believed to have a source of ‘dark energy’.
One of the mysteries of the universe that scientists are still working to solve is “black hole” in the center of many galaxies It is the most gravitational object in the universe. It is caused by the extinction of a massive star. It is said to have such a strong gravitational force that it can absorb everything, even light. Except for the black hole itself.
But a recent study by a team of scientists has led to the assumption that Although black holes have very strong gravitational abilities, But at the same time, it also contributes to the expansion of the universe.

How rare are “water planets” in the vast universe?
Does the universe have an “end”? Is the end of the universe real or just a metaphor?
How does a strong gravitational force expand the universe? One team of researchers, from countries and institutions around the world, said: They compared the growth rates of black holes in different galaxies and found that there is a mass diffusion that is thought to be caused by the cores of galaxies. “Dark Energy (Dark Energy)” which is the mysterious energy behind the rapid expansion of the universe.
Researchers compare black hole masses in young galaxies where stars are still forming with the black hole masses in giant galaxies that are dormant (dormant), where no more stars are formed
in a young galaxy Black holes have been found to grow by consuming stars and other nearby objects. But in that ancient galaxy Leaving a few objects for them to absorb. and it turns out Black holes in dormant galaxies are 7-20 times more massive than expected, indicating that There is a process other than star-eating that causes black holes to grow.
They therefore assessed that The inside of a black hole is likely to contain some sort of energy. That is dark energy itself. Of course, if it can be proven that The growth of black holes is related to the expansion of the universe.
The team of scientists said Dark energy is likely generated and stored in the black hole. Not distributed throughout spacetime as many physicists have assumed.
Duncan Farrah, an astronomer at the University of Hawaii, said: “We assume that Black holes are the source of dark energy… This dark energy occurs when normal matter is compressed during the death and demise of a massive star.”
Chris Pearson of the RAL Institute of Astronomy in the UK. One of the researchers said “The significance of this work is to link the theory of black holes with dark energy cores for the first time to tangible observations of the universe … These black holes are expected to gain mass. up as the universe expands.”
If this study by the team of scientists is correct. This means that they will be able to solve the mystery of one of the most mysterious sources of power in the universe. But much more study is needed. before this theory was accepted. Especially the question that How can a black hole pull everything nearby towards itself and at the same time expand the universe apart?
Vitor Cardoso, a physics professor at the Niels Bohr Institute in Denmark, who was not involved in the research, said while the idea merits scrutiny, it is still in the works. But it’s still too early to associate black holes with dark energy.
“There are a number of arguments and facts that must be understood for this assumption to stand,” Carsodo said.
He adds, “The relationship this study studied between black hole mass and the rate of expansion of the universe is quite shallow. And not supported by fundamental principles … It is too early to think that black holes are related in any way to dark energy.”
Farrah agrees that There is still much to be studied. “Of course we didn’t prove anything here. The evidence we have found only makes this idea worthy of further investigation and testing. But more studies will be needed to confirm or disprove this assumption.”
