''Antimatter Explained'. CERN Research Finds “The Universe Should Not Actually Exist”

With exactly equal amounts of matter and antimatter, our universe is perfectly symmetrical. While that sounds beautiful, it creates a huge problem with existential consequences. Because it possesses this fundamental symmetry, our universe shouldn’t exist at all.

Matter would be the contents of an egg.
Antimatter would be the shell?
Together creating a single dimention.
11 eggs + 11 shells = String theory?

Why must more matter than antimatter have been produced? Suppose there is a small, non-electromagnetic force pushing them away from each other. Then electrically neutral aggregations just accelerated in different directions and separated. Hence, locally there'd always only be 1 kind of matter (that's where we started). There would also be huge parts with nothing (which we see) and almost no parts where matter+antimatter annihilate each other (which we don't see). This also explains the universe's ongoing expansion: antimatter is still there and pushing us.
