According tomedia reports, the universe is expanding, and the expansion is accelerating, but exactly why this happened and how it happened is not yet known. There is a hypothesis that this expansion is driven by mysterious black hole-like objects made up of dark energy, and now astrophysicists have theoreticalized how these objects magicalize the universe — and where they all go.
For more than half a century, it has been known that the universe is not static — it is expanding. In 1998, two groups of astrophysicists each came to the surprising and Nobel Prize-winning conclusion that the expansion of the universe was accelerating.
The driving force behind this acceleration is called “dark energy”, which is calculated to account for about 68% of all things in the universe. But we still don’t know what it is.
An edge hypothesis holds that this unknown form of energy may lurk in a strange type of object called a common dark energy object (GEODE). To external observers, these objects are very much like black holes, but they are made up of dark energy cores surrounded by a rotating layer.
Now, a new study has come up with a new explanation. Researchers from the University of Hawaii calculated that the speed at which the outer layers turn changes the way they move relatively. If they rotate slowly, GEODE will come together very quickly — actually faster than a black hole. This is because of the incredible detail that GEODE will get mass from the expansion of the universe itself. But if the outer layer rotates much faster and approaches the speed of light, GEODE will begin to repel each other. The team says this rejection effect may be the main reason for the accelerated expansion of the universe.
“This reliance on spin is really quite unexpected,” said study co-author Duncan Farrah. If observed, this would be a completely new phenomenon. “
The researchers say the new study supports the idea that if GEODE exists, it could solve the dark energy problem quite subtly. By adjusting some of Einstein’s equations, the team worked out how it worked.
In the scenarios they describe, many of the first stars to be born may end up forming GEODEs rather than black holes in their lives. Over time, these GEODes absorb stars, dust, gases, and other substances, then slowly grow bigger and rotate faster. As they accelerate, they begin to repel each other, just like everything else in the universe — leading to accelerated expansion.
The team says the story is consistent with other cosmic observations. There are now enough ancient stars to produce enough GEODEs to explain the measured acceleration, and GEODE is not confused with the cosmic microwave background because they were born hundreds of millions of years after these radiations were sent out. Most importantly, they don’t destroy the shape of galaxies, because they push themselves away from glowing matter before they flash. In fact, these days it’s reflected in the huge voids that can still lurk between galaxies.
Of course, matching these objects to existing cosmic stories is one thing, and trying to find direct evidence is quite another. The team says it will be difficult to prove the existence of GEODE because they look very much like black holes, even when measured by gravitational wave observatories. But further investigation may help to find new clues.
The study was published in the Journal of Astronphysical.
