why there is more matter than matter why there cant be a universe with more antimatte than matter

The question of the nonexistence of antimatter is one the open questions of current physics. The qualitative explanation has to do with nonconservation of parity under the weak force. However no one has worked out the details leading to the loss of anitmatter.

Note that if the universe was largely antimatter, rather than matter, then we would call that matter (and what we currently call matter would be antimatter).

Experts believe at the start there was a tiny bit more matter than antimatter, so when all the matter and antimatter cancelled out, there was only a tiny bit of matter left over, and that matter is all the matter in the observable universe.

Experts believe at the start there was a tiny bit more matter than antimatter, so when all the matter and antimatter cancelled out, there was only a tiny bit of matter left over, and that matter is all the matter in the observable universe.

Which would make sense in terms that there is only about 5% estimated total matter in the universe, the rest being made up of dark matter and energy.
