Light bends differently at different wavelengths and is scattered. Without a correction lens to reestablish focus, light is hopelessly scattered and defused. Shine a light into a curved mirror or a prism…
The new curved TVs scatter background reflections so it does not interfere with the movie picture.
Any gravity field strong enough to bend light, will also have a time distortion. This will change the lights frequency to a lower level. (Blue light will be made red. Speed or direction does not change the frequency of light, just its amplitude)
Magnetism also causes resistance. A galaxy with the strong magnetic field would also distort light near it.

One of Enstein’s truly beautiful predictions confirmed extensively.

This is quite an accomplishment. I’m wondering if they’re getting useful spectra of the initial blast.

It seems that gravitational lensing is a fairly well understood phenomena with some spectacular photos of the effect captured by Hubble. Dark matter on the other hand still seems very much a mystery.
