This is my own theory

Abstract
This paper explores the hypothesis that black holes may serve as conduits to alternate universes composed entirely of antimatter and other exotic matter forms beyond the standard baryonic matter known in observable physics. The theory proposes that the extreme gravitational and quantum conditions within black holes could invert matter properties, creating a mirror-like universe where antimatter dominates. This concept challenges conventional cosmological models and offers a speculative framework for understanding the relationship between matter, antimatter, and the multiverse.

Introduction
Black holes remain among the most enigmatic phenomena in astrophysics. Traditionally described as regions of spacetime where gravity is so intense that nothing, not even light, can escape, they represent the ultimate collapse of matter. However, the nature of what occurs beyond the event horizon remains unknown. Theoretical physics has long speculated about the possibility of black holes connecting to other regions of spacetime, such as wormholes or white holes. This paper extends that speculation by proposing that black holesmay lead to alternate universes composed of antimatter and other non-baryonic matter forms.

Theoretical Framework
The foundation of this hypothesis lies in the symmetry between matter and antimatter. According to quantum field theory, every particle has a corresponding antiparticle with opposite charge but identical mass. The observable universe, however, is overwhelmingly composed of matter, raising the question of where all the antimatter went after the Big Bang. One possible explanation is that antimatter was not annihilated but rather displaced into alternate universes through black hole singularities.

When matter collapses into a black hole, it experiences extreme compression and energy transformation. At the singularity, where density becomes infinite and known physics breaks down, it is conceivable that matter undergoes a phase inversion. This inversion could convert matter into antimatter or even into exotic forms such as dark matter or hypothetical “mirror matter.” The resulting output might not remain within our universe but instead emerge in a parallel universe governed by reversed physical constants.

Mechanism of Transition
The event horizon may act as a boundary between universes. As matter crosses this threshold, its quantum information could be restructured rather than destroyed. The Hawking radiation process, which slowly evaporates black holes, might represent a form of quantum leakage between universes, maintaining conservation of information across dimensions. In this model, the singularity functions as a bridge, not an endpoint, transferring matter-energy into an antimatter-dominated realm.

Implications for Cosmology
If black holes indeed connect to antimatter universes, this could explain the apparent imbalance between matter and antimatter in our cosmos. Each black hole could serve as a generator of new universes, each with inverted physical properties. This would align with multiverse theories suggesting that our universe is one of many, each with distinct constants and compositions. Furthermore, the existence of antimatter universes could provide insight into dark energy and the accelerating expansion of space, as interactions between universes might influence cosmic dynamics.

Potential Observational Evidence
While direct observation beyond an event horizon is impossible, indirect evidence could support this theory. For instance, unusual gamma-ray emissions or asymmetrical Hawking radiation signatures might indicate antimatter interactions at the quantum boundary. Additionally, if antimatter universes exert gravitational influence on our own through higher-dimensional connections, subtle anomalies in cosmic background radiation or gravitational wave patterns could reveal their presence.

Conclusion
The hypothesis that black holes serve as gateways to antimatter universes offers a speculative yet intriguing perspective on cosmic structure. By reimagining black holes as portals rather than endpoints, this theory provides a potential explanation for the matter-antimatter asymmetry and expands the conceptual boundaries of the multiverse. Further theoretical modeling and indirect observational studies could help determine whether these antimatter realms exist and how they interact with our own universe.

The science is in the details. What qualifies as an “unusual” gamma emission? How do you detect Hawking radiation and what constitutes “unusual” for it? What are the predicted anomalies in the CMB or gravitational waves?

Without an actual model, what you have is a narrative.

I’ll try finding that out soon, and update it

If this were an actual scientific hypothesis, these would be things you already know.

Unusual gamma emissions:

• Energy levels that don’t match known astrophysical sources (like excess photons above 100 GeV).

• Irregular timing or steady emissions where bursts are expected.

• Asymmetrical radiation patterns around black holes.

Hawking radiation detection:

• Direct detection is nearly impossible for large black holes — the signal’s too faint.

• Researchers look for evaporating micro‑black holes or use lab analogs (like Bose–Einstein condensates).

• “Unusual” Hawking radiation would show non‑thermal energy distributions, odd polarization, or particle ratios that suggest information leakage.

Predicted anomalies in the CMB or gravitational waves:

• CMB: unexpected hot/cold spots or polarization asymmetries that break mirror symmetry.

• Gravitational waves: phase distortions or missing energy inconsistent with general relativity, possibly hinting at cross‑dimensional energy transfer.

The fact that "we don't know" is not a license for guesswork.

I could just as easily propose that the current symmetry between matter/anti-matter wasn't always so, but was broken ( one extra matter per billion pairs during the early periods of the Big Bang ), allowing for excess of matter to dominate in the present day.
Such conditions might have arisen during the inflationary period, and then symmetry established when it ended.

We do have examples of symmetry breaks ( electro-weak break ); is a symmetry establishment so far fetched ?
( as far fetched as 'negative' universes on the other side of a BH ? )

Theories should be based on what we do know; such as observational evidence/experiment.

All of these things need to be quantified. You need math.
