> A special combination of physics led to a proton having roughly the same mass as a neutron; perhaps in the dark matter mirror, that combination of physics played out differently, causing the "dark proton" to evaporate and leave behind a sea of "dark neutrons" — what we identify as dark matter. I don't think I misread the article. Currently we expect dark matter to be neutral. So if we assume the statement is correct, what would then happen to the positrons and it's charge?
