Justin Khoury, Professor of Physics and Astronomy, has been featured in an article in Quanta Magazine regarding his research on Dark Matter. Prof. Khoury, together with former Penn postdoc Lasha Berezhiani, recently proposed that in the cold, dense environment of the galactic halo, dark matter condenses into a superfluid — an exotic quantum state of matter that has zero viscosity. If dark matter forms a superfluid in galaxies, it could give rise to a new force that would account for some observed properties of galaxies that remain unexplained in the standard dark matter framework.
