Untestable hypotheses

The current theory is that matter and antimatter must be created in equal amounts, in pairs; however, in our universe matter vastly overwhelms antimatter. Was there a slight imbalance in the amounts created? Does antimatter decay faster than matter? Did all the antimatter get pushed to distant galaxies or sucked into a parallel universe?

Annihilation of an electron and a positron at rest produces two gamma ray photons; that is, annihilation produces pure energy; however, other types of matter-antimatter collisions are more complex. Annihilation of a proton and an antiproton produces mesons that decay into photons, positrons, electrons, and neutrinos.
