how does cosmology explain that the creation of the universe was not a perfect uniform event in all directions type thing. I mean if you took a chunk of the universe and looked at it the density of matter wouldn't be uniform some planets are bigger than others and so forth. Maybe im looking at it the wrong way but the initial creation would have to be pretty bizzare i think to produce what exists. And does anti matter repel matter? since matter attracts matter I thought anti matter would attract anti matter and anti matter and matter would repel.
