What Caused the Asymmetry Between Matter and Antimatter in the Early Universe?

In summary, the conversation discusses the significance of the number 10^9 and its relation to the creation of matter and antimatter. It is believed that there is an asymmetry between decaying X boson-anti X boson pairs, which resulted in one part of matter for every billion boson pairs that annihilated. This occurred about 10^-32 seconds after the Big Bang, when all virtual particles and antiparticles became real due to the separation of the Super Force. The reason for this asymmetry is still being researched and is known as baryogenesis.

To me 10^9 is more special than velocity of light..thats why we exist?

1. why there is one more baryon than 10^9 anti baryon? what is so special with this number?
2. at what time matter and antimatter created? is it at t=0 or few seconds after big bang?
3. at what time they started annihilating? why didn't annihilate before?

This is a rather complex version of how antimatter got the short end of the stick, so to speak. The quick version of the explanation is that there was an asymmetry between decaying X boson-anti X boson pairs that left something like one part of matter for every billion boson pairs that annihilated. This happened about 10^-32 seconds after the Big Bang. At this point in the early universe however, all the virtual particles and antiparticles were real because of the energy level created by the separation of the Super Force.

What is so special about 10^9?

10^9, or one billion, is a significant number in the scientific world for several reasons.

What is the significance of 10^9 in the metric system?

10^9 is equivalent to one gigabyte, which is a commonly used unit of measurement in the metric system for data storage and transmission.

Why is 10^9 often used in astronomy?

10^9 is equivalent to one billion years, which is a common unit of time used in astronomy to measure the age of objects in the universe.

How does 10^9 relate to the speed of light?

In meters per second, the speed of light is approximately 3 x 10^8. This means that light can travel 10^9 meters in approximately 3 seconds, making it a convenient unit for measuring astronomical distances.

What is the significance of 10^9 in genetics?

In genetics, 10^9 is often used to represent the number of base pairs in a human genome, which is approximately 3 billion base pairs.
