Possible Explanation for Baryon Asymmetry

In summary, the imbalance between matter and anti-matter in the universe is a result of the direction of time. Reversing the direction of time would result in anti-matter being more prominent, and at singularity there is a balance between them. The interaction between them at singularity may lead to the release of Hawking radiation. The current asymmetry between matter and anti-matter is not fully understood, and it is speculated that there is a violation of T symmetry similar to the violation of CP. This violation may have caused the domination of matter in the early moments of the universe, and this phenomenon is still not fully understood.

The reason why there is far more matter than anti-matter in our universe is because we are going forward in time. But if we reverse the direction of time anti-matter will become more prominent and I believe that at singularity there is a balance between both of them. The interaction between them at singularity might release Hawking radiation.

About the time, you just make a speculation. Of course there "should" be a violation of T symmetry as there is a violation of CP (such that CPT would be conserved). But in any case we don't know what causes the current CP asymmetry which would allow matter abundances to be so great in comparison to antimatter. Once (if what we have verified so far) there should be #matter=#antimatter... For some reason (still unknown) this stopped working and you got a "matter" dominated universe. And this didn't happen throughout the history of the universe, but it happened during the very first moments of it.

What is baryon asymmetry?

Baryon asymmetry is a term used in physics to describe the unequal abundance of baryonic matter and antimatter in the universe.

Why is baryon asymmetry important?

Baryon asymmetry is important because it is one of the biggest unsolved mysteries in physics. It is crucial to understand how and why the universe contains more matter than antimatter, as this has implications for our understanding of the fundamental laws of nature.

What are some possible explanations for baryon asymmetry?

Some possible explanations for baryon asymmetry include processes such as baryogenesis, which involves the creation of more baryons than anti-baryons in the early universe, or leptogenesis, which involves the asymmetry between particles called leptons and their antiparticles.

How do scientists study baryon asymmetry?

Scientists study baryon asymmetry through various experiments and observations, including studying the cosmic microwave background radiation and conducting experiments at particle accelerators. They also use mathematical models and theories to try to explain the phenomenon.

Is there any evidence for baryon asymmetry?

Yes, there is evidence for baryon asymmetry in the observed universe. The current ratio of baryonic matter to antimatter is about one billion to one, which is a significant asymmetry. However, the exact cause of this asymmetry is still not fully understood.
