I have a couple of comments, if you allow me to do so.
If it had happened that antimatter won, there would be no element of our physical Universe (not even us), since both would have destroyed each other in whirlwinds of pure radiation, abandoning energy and a brilliant Universe, but without any characteristic trace.
This is not fully true. What you describe is what occurs if both are there in the same amount.
Dark matter does not emit or reflect any kind of light. It does not give off any type of radiation, neither visible nor invisible. That's why we cannot see it. And then, how do we know that it exists? Well, this is because it emits gravity and this if we can detect it.
We can detect dark matter. There are experiments targeting its directs detection through its interaction with usual matter, and other experiments aiming at indirect dark matter detection through the products of its annihilation elsewhere in the universe. Moreover, we are also trying to produce dark matter at colliders. The reason is that dark matter can be weakly interacting (other options exist but let's avoid them at the moment). It thus interacts much strongly than trough gravity with matter.
I believe that they are the same there, there is not an asymmetry between them, apart from that I think that this asymmetry is corrected in movement, in what is matter. I do not think that matter can be separated from antimatter, in matter no, the symmetry of them would lead us to photons, and to the symmetry of matter and antimatter, we would not have a balance point between asymmetries, it would be a point of equilibrium , there would be no internal electromagnetism, nor external to the point of equilibrium, there would be an apparently mobile medium.
This looks incorrect to me. Do you mind clarifying and proving your statements. How does matter motion matter here? Why can't matter be separated from antimatter (take a PET scan for instance or the LEP collider).
