Can black holes hold the key to the origin of our universe?

In summary, the paper discusses the concept of a universe inside a black hole with spin and torsion, where the coupling between spin and torsion prevents singularities and creates a nonsingular, nearly flat, homogeneous, and isotropic universe on the other side of the event horizon. This could potentially explain the origin of our universe from within a black hole in another universe. However, this idea has been met with skepticism due to previous unconventional ideas proposed by the author.

Universe in a black hole with spin and torsion

The conservation law for the angular momentum in curved spacetime requires that the antisymmetric part of the affine connection (the torsion tensor) is a variable in the principle of least action. The coupling between spin and torsion generates gravitational repulsion in fermionic matter at extremely high densities and avoids the formation of singularities in black holes. We show that every black hole in the presence of torsion forms a nonsingular, closed, nearly flat, homogeneous, and isotropic universe on the other side of its event horizon. Quantum particle production in such a universe can generate a period of exponential expansion which creates an enormous amount of matter in that universe. Accordingly, our Universe may have originated from the interior of a black hole existing in another universe.

I thought the big bounce origin of our universe was disfavored, what do you think?

This is not the first idea by Poplawski that was 'out there'.
 

1. What is a black hole?

A black hole is a region in space where the gravitational pull is so strong that nothing, not even light, can escape from it. This is caused by the collapse of a massive star, resulting in a singularity – a point of infinite density.

2. Can the universe exist inside a black hole?

It is currently unknown if the universe can exist inside a black hole. Some theories suggest that the singularity at the center of a black hole may connect to another universe, but this is purely speculative and has not been proven.

3. How does time behave inside a black hole?

According to Einstein's theory of relativity, time slows down near massive objects due to their strong gravitational pull. Inside a black hole, where the gravitational pull is infinite, time would essentially stop. This means that anything that enters a black hole would appear to be frozen in time from an outside observer's perspective.

4. Can a black hole destroy the universe?

While black holes have incredibly strong gravitational pull, they are not capable of destroying the entire universe. However, they can have a significant impact on the surrounding space and objects, such as ripping apart stars and planets that come too close.

5. Is it possible to enter a black hole?

It is theoretically possible to enter a black hole, but it is not advisable. The intense gravitational pull would stretch and compress a person's body, ultimately leading to their demise. Additionally, the extreme conditions inside a black hole would make it impossible for anything to survive.
