SUMMARY

The discussion centers on the asymmetry between matter and antimatter in the early universe, specifically addressing the phenomenon where one baryon exists for every billion antibaryons. This asymmetry is attributed to the decay of X boson-anti X boson pairs, which occurred approximately 10^-32 seconds after the Big Bang. The energy levels during this period were significant due to the separation of the Super Force, leading to the predominance of matter over antimatter.

PREREQUISITES
  • Understanding of baryogenesis and its implications in cosmology
  • Familiarity with particle physics concepts, specifically X bosons
  • Knowledge of the Big Bang theory and its timeline
  • Basic grasp of virtual particles and their role in particle interactions
NEXT STEPS

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.
