In your Universe however, there was a tiny bit more of one substance (let's call it Matter 1) than there was of the other (Matter 2), and so after the neutralization, a little smidge of Matter 1 remained, whereas all the Matter 2 was gone forever. You humans call Matter 2 by the term 'anti-matter', and the Observable Universe is that smidge of Matter 1.
It's all rubbish of course, because it's all about thought wars and residual ideas. You can begin to understand how your Universe is structured and operated in the book series called UPWavers.
