Liputan6.com, Hawaii – Scientists unravel a radical claim that energy from black holes is the cause of the universe’s expansion. The expansion comes from strength “dark energyor the dark energy at the core of the black hole.
Reported The GuardianThursday (16/2/2023), physicists actually assume that dark energy it is scattered in space-time, however, scientists from the University of Hawaii say dark energy actually form inside a black hole when there is power from a collapsing star.
Dark energy is a term to describe an unknown force acting against gravity. The reason is, gravity should slow down the expansion of the universe, then the question arises what can speed up the acceleration process, and scientists answer with dark energy.
Now, experts from the University of Hawaii say dark energy it comes from a black hole.
“We propose that black holes are the source of dark energy,” said Duncan Farrah, an astronomer at the University of Hawaii.
“Dark energy is produced when normal matter is compressed during the death and collapse of massive stars,” explains Farrah.
This research is published in The Astrophysical Journal and The Astrophysical Journal Letters.
For information, black holes can absorb stars that are too close.
The University of Hawaii’s claim was met with skepticism from some experts, although they acknowledged the idea was worth scrutinizing.
Vitor Cardoso, professor of physics at the Niehls Bohr Institute in Copenhagen, said there were a number of counter-arguments that could counter claims that black holes have dark energy.
“The relation that the work investigates is somewhat naive between the mass of a black hole and the expansion of the universe,” said Cardoso. “And not supported by fundamental principles.”
“What this study can also tell us is something as simple as ‘black holes develop differently today than billions of years ago,” Cardoso added. “It is premature to think that black holes are related dark energy.”
Farrah also admits that his studies haven’t proven much, but he says his studies are worth examining and testing.
Meanwhile, Ofer Lahav, professor of astronomy from University College London, gave a warmer response.
“Given the mysterious nature of dark energywhich has been thought to have had many incarnations over the last century, it is healthy to consider fresh ideas and think about how they can be refuted,” said the astronomer.
