The standard cosmology model can be the best explanation we have about why the universe is as it is and how everything happened. But this is not only Explanation.
Enter the cosmology of the black hole. This is a radical idea that the Big Bang offers – the rapid unraveling of an infinitely dense point that is thought to have given birth to space, as we know it – actually consisted in a black hole that formed in a more “parent” universe.
Ergo, all of us – and every star, planet, galaxy and the Internet Rando – we live inside one of these mysterious features.
Enrique Gactanaga, a leading author of New study Posted in the magazine Physical Review D and a professor at the Institute of Cosmology and Gravity at the University of Portsmouth isIt is not the first to offer this controversial idea. But the research of his team suggesting a new model to present how this hypothetical scenario took place.
“Our calculations suggest that the Big Bang was not the beginning of everything, but more recently the result of a gravitational crunch or a collapse that forms a very massive black hole – followed by a bounce inside it,” Gactanaga writes in essay for The conversation.
There are certainly many holes that you can push in the standard model. Why is it more important than anti-maturity when the universe should be the same? Why did the universe suffer a period of “space inflation” in which it expanded more than light speeds and then stopped? And why Is it today’s expansion rate that seems to be different depending on how we measure it?
Gactanaga’s main grip seems to be our present understanding of singularity. For him, the idea of the universe, which begins as a point of infinite density, is extremely unsatisfactory.
“This is not just a technical problem; it is a deep theoretical problem that suggests that we do not understand the beginning at all,” he writes.
Gaztanaga also strives for other comfortable cosmological structures such as Dark Energy, which aims to explain why the expansion of the universe is mysteriously accelerated. This hypothetical force is thought to make up 68 percent of the universe, but is completely imperceptible, leaving a place for different scientists to question its existence.
Rethinking the peculiarities can well solve many of these puzzles. We return to Gactanaga’s paper.
“The gravitational collapse should not end in singularity,” he writes about ConversationS “Our mathematics show that when we approach potential singularity, the size of the universe changes as a (hyperbolic) function of space time.”
This is a bold claim. The consensus is that the gravitational collapse – like a star that throws into a black hole – should lead to infinitely dense singularity. What is arguing Gactanagh is happening instead, that the collapse not only stops that it completely crushes the issue, but also turns the course – “rebound” to its terminology.
“What appears on the other side of the bounce is the universe as remarkably like our own,” Gactanaga explains. “Even more surprisingly, the bounce naturally produces the two separate phases of accelerated expansion – inflation and dark energy – led not by hypothetical fields, but by the physics of the rebound itself.”
This is a compelling explanation, but there are many things that remains to prove itself. It relies on discounting some very well -established physics behind the features. The standard model may not be perfect, but it is the standard for a reason. It will take a lot more to dethroned it, and Gaztanaga is an optimistic that future missions like Ararakihs of the European Space Agency, which will study the invisible structures of dark matter to test the model, can reveal the answers we are looking for.
