In astronomy, Galaxy clusters are just areas where the density of galaxies is above average and voids are areas where the density is below average. Galaxies attract each other, so the material for Galaxy clusters has to come from somewhere, and that somewhere is voids.
Saw a video about this. Apparently galactic voids are pretty hard to enter for reasons that elude my 6am brain. Something to do with gravity.

I think it’s to do with the combined gravity of the “strings” of galaxies, stars, etc. being far stronger than nearly nothing.
So a black hill.
