Black Holes Might Be Hiding Cores Of Dark Energy
Black holes, the enigmatic space objects that lurk at the center of all large galaxies, have always been surrounded with mystery. Scientists and space enthusiasts are constantly coming up with new research around black holes in the hope of uncovering something new. To that end, a pair of researchers, Kevin Croker, astrophysicist from the University of Hawaii and mathematician Joel Weiner, have come out with a theory that suggests Einstein's general theory of relativity might need some modification. They have identified an error that was made in Einstein’s equations surrounding growth of our universe, reports Phys.org.
“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. 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,” mentioned Croker.
Researchers state that Erast Gliner, a young physicist at the Ioffe Physico-Technical Institute in Leningrad, proposed an alternative hypothesis stating that very large stars should collapse into what is called Generic Objects of Dark Energy (GEODEs). These GEODEs look identical to black holes on the outside but consists of “dark energy” instead of singularity on the inside. Researchers made the required changes and showed that if fraction of old stars collapsed into GEODEs instead of black holes, then they would naturally become capable of producing the required uniform Dark Energy. However, it must be noted that not all black holes are GEODEs.They only fall under GEODEs if they output dark matter without any gravitational singularity.
However, researchers have separated their theoretical results from observational support of a GEODE scenario. “Black holes certainly aren't dead. What we have shown is that if GEODEs do exist, then they can easily give rise to observed phenomena that presently lack convincing explanations. We anticipate numerous other observational consequences of a GEODE scenario, including many ways to exclude it. We've barely begun to scratch the surface,” added the rese
