A citizen scientist validates General Relativity.

That's what I was thinking, although I haven't heard of applying dark matter to light bending.

Here is a recent article using 'micro-lensing' to map out the distribution of dark matter.

Here, the lensing is from the interaction of the light with gravity produced from the dark matter.

Previously, larger scale lesning has been used to detect dark matter in clusters of galaxies, which was one way we concluded that dark matter really exists (as opposed to a difference in the law of gravity causing the effects we see).

Thanks !
