The latest research estimates that the observable universe houses 200 billion galaxies spread over a wide variety of distances. The further a galaxy is, the faster it seems to move away from us as the fabric of space itself develops. This means that over time, the material continues to expand and become less dense as the volume of the Universe soars.
It also means that, looking back, the universe is reduced to a singularity, a cosmological model known as the Big Bang theory.
Maybe the uniqueness of the universe looks like the singularity at the center of a black hole
A team of radical astrophysicists from the University of Waterloo, Canada, proposed replacing the Big Bang with a different singularity: a black hole.
A black hole is a region of space-time with a gravitational acceleration so powerful that nothing, even light, can escape.
At the center of the black hole is a gravitational singularity, a one-dimensional point that contains an incredibly huge mass in an infinitely small space.

Density and gravity become infinite in a singularity and space-time curves in infinity, meaning that the laws of physics as we understand them cease to function.
But although black holes and the Big Bang share singularities, there is a significant difference between them.
The universe is protected from the chaos of the singularity of a black hole by its horizon of events, the cosmic catchment area from which nothing can escape.
Robert Mann, professor of physics and applied mathematics, explained to Express.co.uk why he and his team had offered to live in a four-dimensional black hole, formed by the collapse of a star at five dimensions.

He said: "This idea was raised about four years ago with Niayesh Afshordi, another teacher in Waterloo.
"The basic idea was that the singularity of the universe may be like the singularity in the center of a black hole.
"The idea was somehow motivated by the unification of the notion of singularity or what is incomplete in the general relativity between black holes and cosmology."
"And so was born the idea that the Big Bang would be analogous to the formation of a black hole, but somehow reversed."

One of the motivations of the University of Waterloo was to propose alternative ideas to conventional images of cosmology, related to inflation.
Professor Mann added, "We also want to connect to the ideas of holography, that gravitational physics in a dimension of space and time equates to non-gravitational physics in a smaller dimension. .
"While this was discussed, the idea was that we would be in the smallest dimension and that's a bigger dimension than we, in a five-dimensional universe, there might be some sort of thing." five-dimensional star that could collapse into a black hole.
"There is an explosion of a membrane of matter in the process and our universe is this membrane, so to speak.

"And this idea was the alternative to the inflationary universe scenario, which is the most common."
This means that our three-dimensional world is only a "membrane" in a much larger universe in four dimensions, according to the theory, using the advanced terminology of string theory.
He continued: "Instead of our universe experiencing a period of rapid expansion and comic inflation, its structure was dictated by gravitational collapse properties of larger dimensions.
"So it's an unconventional idea, but it's an idea that obviously can not be excluded. So we decided to explore it. "

It is important to note that, from the point of view of theoretical science, the proposal of astrophysicists makes it possible to test predictions.
One of them is that there should be fluctuations in microwave cosmic background radiation, the big bang echo.
However, this has not yet been detected in the latest data from the Planck Observatory of the European Space Agency.
