Main Question or Discussion Point
If equal amount of matter and anti-matter was created during the Big Bang, what is existing now? Matter?
... baryogenesis is the generic term for hypothetical physical processes that produced an asymmetry between baryons and antibaryons in the very early universe, resulting in the substantial amounts of residual matter that make up the universe today.
it is puzzling that the universe does not have equal amounts of matter and antimatter. .......There are two main interpretations for this disparity: either the universe began with a small preference for matter ....or the universe was originally perfectly symmetric, but somehow a set of phenomena contributed to a small imbalance in favour of matter over time.
The energies right after the big bang were so high that high radiation and matter/antimatter pairs were constantly being created and annihilated until the temperature of the universe dropped too low for matter/antimatter creation to take place. Conservation and symmetry laws require that matter and antimatter be created in equal amounts, so unless something violates one of these laws, there should have been equal amounts of matter and antimatter. Since we live in a matter dominated universe, we assume that some decay process violates one of these laws, we just don't know exactly how the occurs yet.Why do we have to assume the presence of antimatter in first place anyway? ( ive to admit i vent read any good books on big bang theory).
According to what i've read. There is a static solution of the bosonic sector of the electroweak standard model known as sphaleron that somehow converts quarks to 2 anti quarks and anti-lepton vice versa.So what you actually saying is that due to some unknown process which probably involves violation of some symmetry laws, antimatter very slowly but steady was converted to matter+ (perhaps ) energy?
