Black holes could be making the universe expand using cores of pure dark energy
Event Horizon Telescope
- A new study states that
dark energyshould be taken into consideration when applying Einstein’s theory of general relativity.
- This means that dark energy within black holes could be pulling at the universe and making it expand.
- The study also implies that the 13.8 billion year old universe has been building up real estate over time.
If GEODEs are taken into account, so are the cores of dark energy inside black holes.
Not all black holes have them. But the ones that do, could be pushing the Universe apart.
"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," said Kevin Croker from the University of Hawaii and lead author of the paper published in The Astrophysical Journal.
"It is now clear that general relativity can observably connect collapsed stars – regions the size of Honolulu – to the behaviour of the Universe as a whole, over a thousand billion billion times larger," he added.
Rewriting the cosmological model
The cosmological model is a mathematical description of the universe. It explains why the universe is the way that it is, and has changed over time.
Currently it’s based on Einstein’s general theory of relativity, which isn’t wrong but may be in need of a little tweaking.
Because if dark energy does exist, it means that the universe has been expanding its real estate over the 13.8 billion years, according to the study.
There have already been two studies this year that point to the universe growing in size — so it’s not a far fetched notion.
The big deal about dark energy
The adjusted model presented in the study takes the impact of dark energy into account. As as result, it shows how our understanding of the universe can be different by applying it.
It would mean that every time a star died, it would have an effect on the universe’s expansion. The expansion, in turn, would also affect the GEODEs.
It should be noted that not all black holes are GEODEs. They’re only GEODEs if they result in dark matter and not a gravitational singularity.
One of the black holes that could possibly be a GEODE is Powehi. It is a supermassive compact object at the center of the M87 galaxy. Powehi was also the first
