Matter, Antimatter, and Micro Black holes

AI Thread Summary
The discussion explores the question of why there is more matter than antimatter in the universe, proposing that micro black holes formed during the Big Bang may have absorbed more antimatter than matter. The concept is linked to Hawking radiation, which involves the production of particle-antiparticle pairs near black holes. The theory suggests that, despite a 50/50 chance of absorption, a random preference for antimatter could explain the observed imbalance. However, the need for a credible mechanism to support this preference is emphasized, as current theories view black holes as neutral in their absorption capabilities. The plausibility of this theory remains open for further exploration and debate.

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.
 

Thread 'Does it make sense to build new radio telescopes?'

TL;DR Summary: In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation. In case of failure to detect alien signals, it will further expand the radius of the so-called silence (or rather, radio silence) of the Universe. Is there any sense in this or is blissful ignorance better? In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation.

Thread 'Could gamma-ray bursts have an intragalactic origin?'

Thread 'Could gamma-ray bursts have an intragalactic origin?'

This is indirectly evidenced by a map of the distribution of gamma-ray bursts in the night sky, made in the form of an elongated globe. And also the weakening of gamma radiation by the disk and the center of the Milky Way, which leads to anisotropy in the possibilities of observing gamma-ray bursts. My line of reasoning is as follows: 1. Gamma radiation should be absorbed to some extent by dust and other components of the interstellar medium. As a result, with an extragalactic origin, fewer...
