So one theory is that all matter has an antimatter mirror and because the universe is not symetrical they don't destroy each other....

We also have a BB theory that says the universe started as extremely hot energy, it cooled a little and particles formed. Well this supposedly means matter and antimatter was created. So when they formed why didn't they destroy each other? I'm basing this on the experiment I saw where a photon collided with a particle to create an electron and positron, ie they were created in the same space and kept apart by electric charge. What would keep them apart during the BB particle formation process?

So is antimatter natural or just the result of artificial experiments?
