Couldn't there be an equal amount of matter and antimatter in the universe. While from what I've read there is little antimatter in the universe as we see it. Isn't it a leap to assume that the universe at the Big Bang had slightly more matter than antimatter? Isn't it just as likely that there still is the same amount of antimatter and matter in the universe, but the reason were here is the lumpy nature of the early universe had it so our little observable corner of it had more matter than antimatter and now matter is just about all we can see? Couldn't there be another corner of the universe beyond our observable horizon where there are galaxies made of antimatter and living beings who call it matter and wonder why there isn't more antimatter? Just some food for thought.
