He speculates it might be possible to exploit the phenomenon of gravitational lensing to see if there are any scattering effects, similar to how a crystal will scatter X-ray light that passes through it.

Such "weak" gravitational lensing can, though, be inferred by collecting data from many galaxies (the LSST will study billions) and measuring how their shapes are distorted on average by the effects of any intervening mass.
