Our universe is so vast that it appears impossible for anything else to exist. Experts are beginning to suspect that our universe might exist inside a fourth-dimensional black hole.

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

## How Does A Black Hole Form

Black holes are created when enormous stars die and collapse into an impossibly dense mass from which even light cannot escape. Scientists refers to the space limit where light cannot leave and no object can return as the event horizon.

Obviously, this sounds familiar, since the cosmos can be seen as its own event horizon. In the first trillionth of a second after the Big Bang, the universe started to expand at a rate faster than the speed of light. Prior to this time, space did not exist, hence the universal speed restriction did not exist either. The expansion of the cosmos slows over time.

Einstein's theory of relativity states that enormous objects "warp" space-time, hence the space-time around a black hole is curved. Seeing black holes would be almost impossible if not for the light and heat that are pulled into them.

The more matter a black hole swallows, the larger it and its event horizon will get. As the black hole expands, the rate at which matter falls decreases. To an onlooker, extreme gravity makes it seem as though nothing is moving. According to the theory of relativity, from the viewpoint of someone sucked into a black hole, time seems normal.

## Are We Currently Inside A Black Hole?

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

Calculating what occurs at the singularity of a black hole is impossible, which is why we get infinities, while the event horizon can be calculated using current knowledge and equations. The matter falls into the 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 hold all the information for all the stuff that has fallen since the big bang.

This information is the universe's information. Surprisingly, the math adds up and provides solutions to crucial puzzles about our universe and black holes, according to researchers at the Perimeter Institute and the University of Waterloo.

"Is that the big bang hypothesis has our relatively comprehensible, uniform, and predictable universe arising from the physics-destroying insanity of a singularity. It seems improbable."

It is difficult to conceive our universe being inside another cosmic black hole. The black hole idea appears to make sense and fill in the missing parts that scientists and experts have been pursuing for a lifetime, leading us to assume that the universe is far larger and weirder than we had previously believed.
