Physicists propose mechanism that explains the origins of both dark matter and 'normal' matter

Physicists propose mechanism that explains the origins of both dark matter and 'normal' matter: "'There are two problems in theoretical physics we are trying to address at once,' Sigurdson said. 'The baryon asymmetry (why do we have atoms but not antiatoms in the Universe?) has really been a problem since Paul Dirac proposed antimatter in 1928 and it was discovered in 1932. And what is the dark matter? Hints of dark matter have been around since Fritz Zwicky discovered missing mass in the Coma Cluster in 1933, but its identity is still unknown. This mechanism links the formation of atoms and dark matter and helps resolve the baryon asymmetry mystery, as the total dark plus visible baryon balance of the Universe is restored.'"
