Matter, Antimatter, and Micro Black holes

In summary, the question of where all the antimatter has gone has been proposed by the book Moment of Creation by James Trefil. The theory that micro black holes produced during the big bang could have absorbed more antimatter than regular matter has been suggested as a possible explanation. However, this theory has not been disproved or confirmed by anyone and it remains a topic of discussion in the cosmology community. Further research and evidence is needed to determine its plausibility.

I have recently been reading Moment of Creation by James Trefil, and I have stumbled upon the question, where has all the antimatter gone? I asked myself, what if micro black holes produced by the tremendous energy at the big bang are the answer? If you have an understanding in hawking radiation then you know particle-antiparticle pairs are produced at balck holes. What if, by chance, antiparticles were absorbed by these micro black holes more than regular particles. It could explain why there is more matter than antimatter. Has this been dissproved by anyone? Is this a plausible theory?

I also posted this in the cosmology section, but it seems that not many people wander there.

Why would a BH prefer to absorb antimatter.

It doesn't even have to prefer, it could happen by chance. Even though there would be a 50/50 chance either way, it could just happen by chance that antimatter was absorbed more by a BH.

A mechanism for this prefence would be necessary to lend it credibility. Black holes are equal opportunity gravity wells according to existing theory.
 

1. What is the difference between matter and antimatter?

Matter and antimatter are two types of particles that have opposite properties. Matter is made up of particles with a positive charge, such as protons, neutrons, and electrons. Antimatter, on the other hand, is made up of particles with a negative charge, such as antiprotons, antineutrons, and positrons. When matter and antimatter come into contact, they annihilate each other, releasing a large amount of energy.

2. How are micro black holes different from regular black holes?

Micro black holes are much smaller than regular black holes. They are thought to be formed by the collapse of extremely small amounts of matter, such as a single particle. They also have a much shorter lifespan than regular black holes, as they evaporate due to Hawking radiation.

3. Can antimatter be used as a source of energy?

Yes, antimatter has the potential to be a very efficient source of energy. When matter and antimatter annihilate each other, the resulting energy can be harnessed for various purposes. However, since antimatter is currently very expensive and difficult to produce, it is not currently a practical source of energy.

4. Are micro black holes dangerous?

Micro black holes are not a significant danger. They are very small and have a short lifespan, so they do not have enough time to grow and become a threat. Additionally, they are constantly evaporating due to Hawking radiation, making them even less of a concern.

5. Can antimatter be used for space propulsion?

Yes, antimatter has the potential to be a very efficient fuel source for space propulsion. However, it is currently very difficult and expensive to produce and store, so it is not yet a practical option for space travel. Scientists are researching ways to produce and store antimatter more efficiently for future space missions.
