Black Holes Could Be the Source of Dark Energy

Two new studies released this month have made some new claims about the source of the unsolved dark energy that drives the expansion of the universe. Accordingly, the source of dark energy may be black holes.

It has been talked about since the 1990s that dark energy, on which scientists have been working for many years, plays an important role in the expansion of the universe. However, the researchers were unable to point to a definitive source for the emergence of dark energy during this process.

Two recent articles have revealed some information about this mystery. According to international researchers black holesIt could be the source of dark energy that drives the expansion of the universe. The findings were published in The Astrophysical Journal and The Astrophysical Journal Letters on Feb. 2 and Feb. 15, respectively.

Studies say dark energy forms in black holes and stays there

Scientists from different countries say that if black holes continue to grow while the universe expands, these objects may be the source of dark energy. The relationship between the growth of black holes and the expansion of the universe depends on where dark energy was stored when it appeared. Previously, experts stated that dark energy spread throughout the universe, causing expansion.

But two new studies suggest that black holes themselves can contain dark energy says. Coming to the question of how black holes create dark energy, the researchers said: the death of the stars pointing out. Studies show that when a star dies and collapses, dark energy is created, and these deaths form the source and contribute to expansion. We know that black holes are formed by the collapse of stars.

Of course on this doubts too available. According to The Guardian, some astronomers are not sure about the findings and state that it is too early to connect black holes and dark energy, and that more research is needed. Regarding this, Vitor Cardoso of the Niels Bohr Institute in Denmark said:If this claim is to survive more than a few months, there are some counter-arguments and facts that must be taken into account.” uses expressions.

Are dark energy and dark matter the same thing?

Finally, dark energy and dark matter it’s not the same thingLet’s say we shouldn’t mix it up. Dark energy is the name given to the force that makes the universe expand. On the other hand, dark matter is believed to act as the pulling force that holds the universe together.

Dark energy is thought to accelerate the expansion of the universe, while dark matter slows it down. Let’s add that both qualify as invisible and yet to be fully identified.
