TFNR - Matter and Antimatter

Brief definition / description of antimatter.

Why don't we observe equal quantities of matter and antimatter in the Universe? Where did all the "primordial" antimatter supposedly formed during the Big Bang go? Why did matter prevail over antimatter? So what is the key to the mystery of matter and antimatter?

Many hypotheses are being evaluated with extremely sophisticated experiments.

In the context of this work, in light of what has been said regarding the process of formation of ordinary matter and the entire Universe, the only hypothesis we can make is that antimatter has simply never been formed and that the very modest quantity of existing antimatter is produced in particular phenomena, in high-energy collisions.

Personally I think that the only plausible answer to this mystery is that "primordial" antimatter never formed, never existed, just like the Big Bang.
