wats the cause of the slight preponderance of matter on antimatter at the beginning of times,(big bang primordial soup) any relevant theory or explications? thanks

In summary, the cause of the slight preponderance of matter over antimatter at the beginning of times (big bang primordial soup) is still an open question. While there is experimental evidence of a slight difference between matter and antimatter reactions, known as C-P violation, it is not enough to fully explain the matter preponderance. Some suggest that the 2008 Nobel Prize was awarded for the "answer" to this question, but this is not entirely accurate. More research and theories are needed to fully understand baryogenesis.

Quantitatively it is an open question. Qualitatively there is experimental evidence that there is a slight difference (C-P violation) between matter and anti-matter reactions which give a hint as to what explains the matter preponderance.

if one has answer to this question, then a Nobel Prize is awaiting for you ;-)

If you are interested you can find a nice introduction to baryogenesis here:

yeah but CP violation alone can not solve it.

nor can the one CKM phase. i was just being obnoxious.

1. What is "slight preponderance of matter on antimatter"?
The concept refers to the fact that there is more matter than antimatter in the observable universe. This is a fundamental asymmetry in the laws of physics and remains a significant unanswered question in science.
2. How do scientists know that there is a preponderance of matter over antimatter?
Scientists have observed the decay of particles containing both matter and antimatter and have found that there is a slight excess of matter particles left over. This has been confirmed through various experiments and observations.
3. Why is there more matter than antimatter in the universe?
This is still a mystery in science and is an active area of research. One theory is that in the early universe, there was an imbalance in the production of matter and antimatter, leading to the preponderance of matter we observe today.
4. What would happen if there was an equal amount of matter and antimatter in the universe?
If there was an equal amount of matter and antimatter, they would annihilate each other, resulting in the complete destruction of both and leaving behind only energy. This is known as the "Big Bang" theory of the origin of the universe.
5. Can we create equal amounts of matter and antimatter in a laboratory?
Yes, scientists have been able to create small amounts of antimatter in laboratories through particle accelerators. However, it is challenging to produce equal amounts of matter and antimatter due to their tendency to annihilate each other quickly.
