something must have happened in that primordial soup that caused the total amount of matter present to become slightly greater than the total amount of antimatter. Even a very small imbalance, if established early enough in our universe’s history, could explain the world we see all around us today. A primordial asymmetry as slight as 10 billion and 1 particles of matter for every 10 billion particles of antimatter would be enough to enable a small but adequate fraction of the matter to survive and escape the early universe intact.
