Universe does seem to exist, though, doesn't it?
How would you explain that without CP symmetry violation?
- scotty79 9y ago> How would you explain that without CP symmetry violation? My preferred explanation is that areas dominated by matter and anti-matter got pushed away far apart by the energy of annihilation between them, universe is much larger than observable universe and our galaxy, neighbouring galaxies, possibly even whole observable universe belongs to region that was dominated by matter that is now separated from anti-matter dominated ones with sufficiently large and empty void. I don't exactly buy the idea that all of the matter was at the beginning in one geometrical point, and exactly uniform. Background radiation is not exactly uniform so imho not all places in space had exactly the same amounts of matter and anti-matter either.
- sethrin 9y agoThe geometrical point you refer to is a projection, not an empirical fact. PBS has an excellent YouTube series called Space Time, which describes the Big Bang cosmology in some detail, in several episodes. I'm not exactly sure which ones, but I could track them down if you like. However, I might recommend the entire series; you might be able to refine your speculation somewhat.
