Protons & anti-protons appear to have same magnetic moment - why did matter dominate?

[gary]

In a 23 Oct 2017 article at Cosmos magazine, Cathal O'Connell reports that
researchers at CERN have made the most precise measurements to date
of the magnetic moment of an anti-proton.

The result - it appears to be identical to that of a proton.

So if antimatter didn't manage to annihilate matter at the Big Bang, it wasn't
because protons and anti-protons had different magnetic moments.

The work is also reported in an article in Nature :-

I call it 50-50 chance, it just happened to be in favour of matter over anti-matter

For us to be here one of them had to triumph. We happen to consider ourselves to be made of matter. The names are arbitrary and could just be reversed. Maybe we are actually anti-matter beings?
