Atomic Structure in Black Hole

TL;DR

This paper proposes a novel atomic-like internal structure for black holes using a mean field gravity approximation, explaining properties like entropy and quantization, and predicts baryon number violation as a testable consequence.

Contribution

It introduces a new atomic-structure model of black holes that explains their properties and predicts baryon number violation, differing from traditional horizon-based models.

Findings

Black holes have an internal structure similar to atoms.

The model predicts a minimum black hole size comparable to a hydrogen atom.

Black holes carry baryon number, which is rapidly violated.

Abstract

We propose that any black hole has atomic structure in its inside and has no horizon as a model of black holes. Our proposal is founded on a mean field approximation of gravity. The structure of our model consists of a (charged) singularity at the center and quantum fluctuations of fields around the singularity, namely, it is quite similar to that of atoms. Any properties of black holes, e.g. entropy, can be explained by the model. The model naturally quantizes black holes. In particular, we find the minimum black hole, whose structure is similar to that of the hydrogen atom and whose Schwarzschild radius is approximately 1.1287 times the Planck length. Our approach is conceptually similar to the Bohr's model of the atomic structure, and the concept of the minimum Schwarzschild radius is similar to that of the Bohr radius. The model predicts that black holes carry baryon number, and the baryon number is rapidly violated. This baryon number violation can be used as verification of the model.
