Masses of dark matter could be traveling throughout galaxies

A new paper suggests that dark matter could collapse into small clusters that could represent up to 10% of our galaxy. The researchers estimate that the formation of these clusters in possible for small quantities of dark matter but large formations, the size of galaxies would not behave as such. The theory still needs to be confirmed by experimental data. For the moment this is an interesting find that may shed light on the mysteries of dark matter.
