The universe is expanding, and that expansion is accelerating, but exactly why and how that’s happening remains unknown. One hypothesis suggests that this expansion is driven by mysterious, black hole-like objects made of dark energy, and now astrophysicists have theorized how these objects work their magic on the cosmos – and where they all went.
The driving force behind this acceleration has been given the descriptor “dark energy,” and it’s been calculated that this stuff makes up around 68 percent of everything in the universe. But we still don’t really know what it actually is.
One fringe hypothesis suggests that this unknown form of energy could be lurking inside an exotic class of objects referred to as Generic Objects of Dark Energy (GEODEs). These objects would look very much like black holes to outside observers, but they would be made up of a core of dark energy, surrounded by a spinning layer.
And now, a new study has suggested an explanation for how these GEODEs might be accelerating the expansion of the universe – and where we might find them.
Researchers from the University of Hawaii calculated that the speed at which the outer layers spin changes how they move relative to each other. If they spin slowly, the GEODEs would clump together very quickly – more quickly than black holes do, in fact. That’s because of the mind-bending detail that GEODEs would gain mass from the expansion of the universe itself.
But if the outer layers are spinning much faster, near the speed of light, then the GEODEs begin to repel each other. And this repelling effect, the team says, could be what largely drives the acceleration of the expansion of the universe.
In the scenario they describe, many of the first stars ever born could have formed GEODEs instead of black holes at the end of their lives. Over time, those GEODEs would have sucked up stars, dust, gas and other material, slowly growing bigger and spinning faster. As they sped up, they would instead begin to repel each other, as well as basically everything else in the universe – contributing to the accelerated expansion.
And most importantly, they wouldn’t have disrupted the formation of galaxies because they would have pushed themselves away from luminous matter before the galaxies were even a twinkle. In fact, that’s where these objects may still be lurking today – in the big empty voids between galaxies.
