If real, dark fusion could help demystify this physics puzzle
The idea could reveal why galaxies have dark matter cores of even densities
DARK CLOUDS Galaxies and galaxy clusters are surrounded by dark matter (illustrated in blue over an image of the cluster Abell 2744; red indicates gas). Dark matter particles may undergo a process called dark fusion, one scientist suggests.
