Some astronomers propose that Earth may lie within a gigantic low-density region of space called a cosmic void.

The idea is controversial, but actively debated in modern cosmology. Cinematic visuals and audio generated with AI. Source: Astrophysical Journal • ESA • NASA • Royal Astronomical Society #Cosmic
