Slight preponderance of matter on antimatter

[cosmicpencil]

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

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.

some might even go so far as to claim that the 2008 Nobel Prize WAS awarded for the "answer" to this question.

yeah but CP violation alone can not solve it.

It is not your fault that some people say that 2008 nobel prize solves baryogenesis :-)
