Reminds me of https://science.nasa.gov/asset/hubble/runaway-black-hole-nea... A supermassive blackhole drawing in dust on such a scale that it's creating new stars in its wake as it zips by. (The picture is my desktop background. I think it nicely illustrates three fundamental shapes of the universe: 1) spheres (gravity dominates), 2) disks (angular momentum winning over gravity), 3) straight lines (no gravity))
