Supermassive Black Holes: A Possible Source of Dark Energy

posted by Jason Kottke Feb 16, 2023

A group of astronomers say they have evidence that links supermassive black holes at galactic centers with dark energy, the mysterious force that accounts for roughly 68% of the energy in the universe. Here's the news release and the paper. From the Guardian:

Instead of dark energy being smeared out across spacetime, as many physicists have assumed, the scientists suggest that it is created and remains inside black holes, which form in the crushing forces of collapsing stars.

"We propose that black holes are the source for dark energy," said Duncan Farrah, an astronomer at the University of Hawaii. "This dark energy is produced when normal matter is compressed during the death and collapse of large stars."

The claim was met with raised eyebrows from some independent experts, with one noting that while the idea deserved scrutiny, it was far too early to link black holes and dark energy. "There's a number of counter-arguments and facts that need to be understood if this claim is going to live more than a few months," said Vitor Cardoso, a professor of physics at the Niels Bohr Institute in Copenhagen.

And here's a short video explainer:

It's a radical claim to be sure — it'll be interesting to see how it shakes out in the weeks and months to come as other scientists interpret the results.
