Scientists Say Black Holes May Be Hiding ‘Pure Dark Energy’

Space lovers have been hearing a lot of news about black holes in 2019, from the first official image of a black hole to the sound its producing. Now, scientists found something mysterious inside these already scary objects. 

A new study, published in The Astrophysical Journal, shows that black holes might contain cores of pure dark energy, which potentially are contributing to the expansion of the universe. The findings support the 50-year-old hypothesis about the existence of bodies called Generic Objects of Dark Energy (GEODEs).

Researchers said scientists have long believed that no material is triggering or contributing to the continuous expansion of the universe, ScienceAlert reported Thursday. The study suggests a correction to the assumption. 

"For 80 years, we've generally operated under the assumption that the universe, in broad strokes, was not affected by the particular details of any small region," Kevin Croker, one of the researchers and an astrophysicist at the University of Hawai'i, said. "It is now clear that general relativity can observably connect collapsed stars – regions the size of Honolulu – to the behavior of the universe as a whole, over a thousand billion billion times larger."

Initial ideas derived from Einstein's theory of general relativity suggested that any matter inside the universe is more or less made of the same materials and is just part of the expansion. This led scientists to ignore movements of stars and galaxies when studying the universe’s growing waistline.

However, researchers of the latest study said that there are things that could be contributing to the expanding space. It is similar to the idea that moving ducks could affect the lake's water. 

These ducks could be the dying stars and black holes that release vast amounts of energy. 

Black Holes and Dark Energy

In 1966, Russian physicist Erast Gliner proposed that there are objects that existed after the Big Bang that could counter the effects of gravity. These unseen objects appear like a black hole from the outside but a bubble of energy pushing the universe. 

Croker and partner mathematician Joel Weiner said that energy could be ancient stars that collapsed into GEODEs. Their calculations suggest that dark energy may really come from merging black holes.

However, the researchers noted more observations are needed to support their study. Astronomers also have yet to confirm the presence of dark energy or GEODEs.

"What we have shown is that if GEODEs do exist, then they can easily give rise to observed phenomena that presently lack convincing explanations," Croker and Weiner said. "We anticipate numerous other observational consequences of a GEODE scenario, including many ways to exclude it. We've barely begun to scratch the surface."
