(ORDO NEWS) — Astrophysicists have suggested that our universe could exist inside a four-dimensional black hole.

Our cosmos began as a singularity, a point in space that was infinitely hot and dense. According to CERN researchers, black holes in our universe may have the same characteristics as those described by the scientific community.

#### How a black hole is formed

Black holes are formed when huge stars die and collapse into an incredibly dense mass from which not even light can escape. Scientists call the event horizon the limit of space where light cannot escape and no object can return.

In the first trillionth of a second after the Big Bang, the universe began to expand at a rate faster than the speed of light.

Until that time, space did not exist, therefore, there was no universal speed limit either. That is, the expansion of space slows down over time.

Einstein’s theory of relativity states that huge objects “curve” space-time, hence the space-time around a black hole is curved. It would be virtually impossible to see black holes were it not for the light and heat they draw in.

The more matter a black hole absorbs, the larger it and its event horizon become. As the black hole expands, the rate at which matter falls decreases.

To an outside observer, because of the strong gravity, it seems that nothing is moving. According to the theory of relativity, from the point of view of someone being sucked into a black hole, time seems to be normal.

#### Are we inside a black hole?

Space contains three-dimensional black holes with two-dimensional event horizons. According to this reasoning, if the universe is an event horizon, it must have originated from a four-dimensional black hole.

It is impossible to calculate what happens at the singularity of a black hole, so we get infinities, while the event horizon can be calculated using modern knowledge and equations.

Matter falls into a black hole and the event horizon encodes it. As the black hole grows, so does the event horizon, so the surface area is just the right size to contain all the information about everything that fell after the big bang.

This information is the information of the Universe. According to researchers at the Perimeter Institute and the University of Waterloo, mathematics provides solutions to the most important mysteries about our universe and black holes.

“The fact is that the big bang hypothesis has our relatively understandable, homogeneous and predictable universe emerging from the physics-destroying madness of the singularity. It seems incredible.”

It is hard to imagine that our universe is inside another cosmic black hole. The idea of a black hole seems to make sense and fills in the missing pieces that scientists and experts have been chasing all their lives, leading us to assume that the universe is much bigger and more mysterious than we previously thought.
