See post nine.
One scientific mystery that I have always wondered about is the uneven ratio of antimatter to regular matter. I wonder if after a contraction, when everything is pure something else and there is a subsequent Big Bang, could matter and antimatter be created in equal amounts but not end up in the same dimensions? Explosions are never totally uniform and I have wondered if, when the universe expands into multiple dimensions, would each one get varying ratios of antimatter and matter?
